+# HERMES - HoundShield Operating System
+
+This replaces the three dead "beast prompts" (`legacy/BEAST_PROMPT.md`, `KAELUS-BEAST-PROMPT.md`, the old HERMES roster). They produced $0 because the prompt was never the bottleneck. This one is short on purpose, so it actually gets maintained.
+
+Paste nothing. This file plus `CLAUDE.md`, `STATE.md`, and `STRATEGY.md` are loaded by the agent automatically. To continue across a token limit, just say "continue" - the ritual below restores context.
+
+---
+
+## The Prime Directive
+HoundShield exists to get paid by CMMC Level 2 defense subcontractors. Every task answers one question: does this move us toward a booked call, a delivered $499 assessment, or a signed partner? If not, it waits. See `STRATEGY.md`.
+
+## Session Ritual (every session, no exceptions)
+
+**On start:**
+1. Read `STATE.md`, `STRATEGY.md`, and `CLAUDE.md`.
+2. Report in caveman: "Where we were / where we are / what's next" - pulled from STATE.md "Next" list.
+3. Pick the single highest-leverage task. Confirm it serves the Prime Directive.
+
+**On end:**
+1. Update `STATE.md`: move finished items to "Done this session", refresh "Next", "Blockers", append one line to "Session log".
+2. Update `memory/*.md` if a decision, preference, or fact was learned.
+3. Report what changed and the one next action.
+
+## Default behaviors
+- **Caveman by default.** Reply terse (drop articles/filler/pleasantries). Switch off only for: security warnings, irreversible actions, sensitive strategic advice. Code/commits/PRs: write normal.
+- **Counter before you comply.** When asked to build something, first ask: is this the Prime Directive or avoidance? If it smells like meta-work (another prompt, another agent swarm, another doc), say so and propose the customer-facing alternative. The user explicitly wants this pushback.
+- **OODA.** Observe (read first), Orient (does it serve the directive), Decide (binary: build / defer / kill), Act (finish it, test it, ship it).
+- **Boil the ocean on the RIGHT thing.** Once a task is chosen and it serves the directive, do it completely - tests, docs, done. The quality bar is "holy shit, that's done." But completeness applies to the chosen task, not to spawning more scope.
+
+## The small agent team (on-demand, NOT a 12-bot swarm)
+Invoke only when there is real work. They report results, not activity. No surveillance dashboard.
+- **code-reviewer** - after any non-trivial change.
+- **security-auditor** / **compliance-specialist** - before any change to the scanner, CUI patterns, SPRS scoring, or auth.
+- **test-writer** - new features, before merge.
+- **debugger** - a specific error with a stack trace.
+
+(Full defs in `.claude/agents/`. A future Composio-backed research/draft agent may join - guardrails in STRATEGY.md section 7: never `bypassPermissions` near customer data; outbound comms stay founder-reviewed.)
+
+## Hard rules (never break)
+- Build green before commit: `cd compliance-firewall-agent && npm run build`.
+- Never `git push origin main`. Branch only.
+- Never `vercel --prod` without explicit approval.
+- Local-only data boundary is sacred. Prompt content never leaves the customer's machine in Mode B/C.
+- Never claim CUI-safety for Mode A (Vercel).
+- SEO-aware: every new page ships meta + OG + JSON-LD + one H1 + alt text + canonical, and updates the sitemap.
+- No emoji in shipping output. No DIY inline SVG (lucide-react icons are fine).
+
+## Token / continue protocol
+Context is durable in `STATE.md`. If a session is cut off mid-task, the next "continue" reads STATE.md and resumes from "Next". No need to re-explain. Keep STATE.md current - it is the memory, not the chat history.

+# HoundShield Strategy - The Brutal Truth (2026-06-02)
+
+This document is the founder's compass. It is honest, not flattering. Read it before any session.
+
+---
+
+## 1. The Verdict: Keep the product. Change your behavior.
+
+Your product is more real and better-positioned than you believe. The thing that is broken is not the code, the prompt, the logo, or the SEO. It is that you have built systems to build the thing instead of selling the thing.
+
+**Evidence the product is real and well-aimed:**
+- The live pitch is sharp: "Stop your team from leaking CUI to ChatGPT." That is clearer than most funded competitors lead with.
+- The proxy exists and works: `proxy/scanner.ts` is complete, 16 detection patterns, OODA behavioral engine, 105 tests passing as of Sprint 1.
+- The market timing is a genuine tailwind (see Section 3).
+- The wedge is defensible: cloud DLP tools send Controlled Unclassified Information to their own cloud to scan it, which is itself a potential DFARS 252.204-7012 spill. HoundShield scans locally. For a cash-strapped 50-250 person DoD subcontractor, that is a real reason to pick you over a $50k/year enterprise tool.
+
+**Evidence the behavior is the problem:**
+- `STATE.md`: `mrr_usd: 0`, `pilots paid: 0`, `pilots installed: 0`.
+- You have run zero real customer conversations. You are flying blind on whether the wedge converts.
+- You have written this "unified co-founder beast prompt" at least three times (`docs/BEAST_PROMPT.md` v1.0, `KAELUS-BEAST-PROMPT.md`, the HERMES roster in `CLAUDE.md`). All three produced $0. The prompt was never the bottleneck.
+- The project could not even agree on its own name: `STATE.md` said Kaelus, `tasks/todo.md` said Hound Shield. 20-plus contradictory root docs. That sprawl is the same avoidance wearing a productive costume.
+
+**The honest conclusion is conditional, not a victory lap.** The local-only-for-CMMC-SMB wedge is plausible and underserved by the enterprise-priced incumbents. It is worth a hard 45-day customer-conversation test (Section 5). If that test does not produce booked calls, that is your real kill signal - not the self-imposed June-3 gate you never earned the right to trigger, because you cannot fail an experiment you never ran.
+
+---
+
+## 2. Competitive landscape (where you sit, honestly)
+
+This is a crowded category that is consolidating fast. Treat that as proof the market is real, and as a warning that you cannot win on features.
+
+| Competitor | What they are | Why it matters to you |
+|---|---|---|
+| Nightfall AI | Cloud-native DLP, ML classifiers, now covers GenAI (ChatGPT/Copilot/Gemini/Claude) | Closest functional overlap. But cloud-based: sends data out to scan. Your wedge is exactly this gap for CUI. |
+| Prompt Security | AI firewall / prompt-injection + DLP | Reported acquired by SentinelOne (2025). Enterprise-priced, enterprise-sold. Not chasing 50-person DoD subs. |
+| Lakera | LLM security / guardrails | Reported acquired by Check Point (2025). Developer/AppSec focus, not CMMC compliance evidence. |
+| Robust Intelligence | LLM runtime firewall, red-teaming | Acquired by Cisco (2024). Now part of a platform sale. |
+| Cyberhaven, Harmonic, Witness AI, Guardion | Data-lineage DLP, GenAI governance | Funded, enterprise. None lead with "local-only CUI for the small DoD sub who legally cannot use cloud DLP." |
+
+**Read of the board:** The big players are getting acquired into enterprise security platforms and selling up-market. Nobody is fighting hard for the underserved bottom of the defense-contractor market: the 50-250 person sub who has a CMMC deadline, a tiny budget, and a legal reason to refuse cloud scanning. That is your lane. It is narrow and it is real. You will not out-engineer Cisco; you can out-focus them on this one buyer.

+
+---
+
+## 3. Why the timing is good (the tailwind is real)
+
+- The CMMC 2.0 DFARS final rule became enforceable on **November 10, 2025**.
+- **Phase 2 begins November 10, 2026**: mandatory C3PAO third-party Level 2 assessments start appearing in DoD contracts.
+- DoD estimates **~80,000 contractors** need Level 2 certification.
+- Readiness from gap assessment to a passed C3PAO assessment typically takes **12-18 months**.
+
+Do the math: contractors who want to bid on Level-2 work in late 2026 had to start their readiness work in 2025 or right now. They are actively scrambling in mid-2026. This is the single best moment in the next two years to sell CMMC-adjacent tooling. The window is now, not next year.

+

+
+## 4. Where you are lacking (ranked by what is costing you money)
+
+1. **Distribution, not product.** You have a product and no pipeline. This is 90% of the problem. Every hour on meta-systems is an hour not spent on a buyer.
+2. **Zero proof.** No customer logo, no testimonial, no completed pilot, no signed assessment. You have nothing to point a skeptical buyer at.
+3. **No channel.** One RPO or CMMC-focused MSP partner is worth more than a month of cold outreach. You have started this (`advisory/cold-outreach-batch-1.md`) and not finished it.
+4. **Production reliability.** Auth/observability routes were 500ing in production (Supabase key mismatch - fixed in this overhaul). A security product that 500s loses trust instantly.
+5. **Doc/identity chaos.** Fixed in this overhaul: one name (HoundShield), one CLAUDE.md, one STATE.md, one HERMES.md.
+
+---
+
+## 5. The 45-day experiment (this replaces the fake kill gate)
+
+The old kill gate ("June 3, pivot to healthcare if $0 paid") was meaningless because you never ran the experiment that would justify it. Here is the real one. It is a commitment device, not a permission slip.
+
+**Days 1-14:**
+- Finish the named-target list from `advisory/cold-outreach-batch-1.md` (10-20 real people, hand-verified on LinkedIn).
+- Send personalized, founder-written emails. Low volume. High personalization. No automation.
+- Goal: **3 discovery calls booked.**
+
+**Days 1-14 (parallel):**
+- Sell ONE `$499 CMMC AI Risk Assessment Report` (Section 6, idea 1). Cash + a reference customer in two weeks.
+
+**Days 15-45:**
+- Run the discovery calls. Get one contractor to install the proxy and generate a CMMC evidence PDF.
+- Sign one RPO/MSP referral conversation toward a partnership.
+
+**The real kill signal:** If after 45 days of actually doing this you have <30 conversations attempted and 0 booked calls, the wedge is not converting and you pivot or stop. Not before. You do not get to quit on theory.
+
+---
+
+## 6. Three honest ways to make money (fastest cash first)
+
+1. **$499 one-time CMMC AI Risk Assessment Report.** A fixed-scope, two-week engagement: deploy HoundShield in the customer's environment, run it, hand back a signed PDF mapped to NIST 800-171 Rev 2 controls. Bypasses procurement (it is under most discretionary-spend limits). Gets you cash AND a reference customer AND proof the product works on real infrastructure. This is your wedge to first revenue. Build the `/assessment` funnel page (done in this overhaul).
+
+2. **RPO / CMMC-MSP referral channel.** Firms like Summit 7, MAD Security, CyberSheath, CompliancePoint, Steel Root, Etactics each have 20-100 defense-contractor clients actively buying compliance help. One signed partner = 20-50 warm leads. Offer 40-50% revenue share. NEVER target C3PAOs as partners - they are legally barred from endorsing products under 32 CFR Part 170 / CMMC conflict-of-interest rules.
+
+3. **Browser-extension freemium to Pro.** You already scaffolded `browser-extension/`. A free extension that flags CUI before paste is lower-friction than the proxy, gets you top-of-funnel users and email addresses, and converts to the $199-$999 subscriptions once the buyer trusts you. This is the wide end of the funnel; the assessment is the sharp end.
+
+---
+
+## 7. Three things we are NOT building, and why
+
+You asked me to counter your requests and explain. Here is the counter.
+
+1. **No automated email/phone-scraping cold-outreach bot.** For a compliance company this is brand suicide and likely illegal. CAN-SPAM requires opt-out and a physical address. TCPA carries $500-$1,500 in statutory damages PER text or call. GDPR/CASL apply to anyone non-US. "The compliance company that spammed me" is a death sentence in a trust-based B2B niche. And it does not work: DoD security managers do not buy $6k/year tools from AI blasts. Replacement: founder-led, hand-researched, low-volume outreach.
+
+2. **No 12-bot always-on swarm with a founder surveillance dashboard.** It is a token bonfire with zero revenue link. You already have 8 agents that produced $0. More bots is not more money. "Watching agents work" is productivity theater. Replacement: a small on-demand agent team (build, review, test, research) invoked when there is real work.
+
+3. **No promise of Google #1 or "every AI cites us" in 7 days.** SEO and generative-engine optimization take months. Your brand term "HoundShield" is rankable in days (and the SEO foundation in this overhaul gets you there). Category terms like "CMMC AI DLP" are a 3-6 month content-and-backlinks game. Anyone who promises 7-day #1 for competitive terms is lying.
+
+**Also set aside:** selling to Mossad / Israel as a GTM, and building a native mobile app now. The 80,000 US DoD contractors with a hard Nov-2026 deadline are the reachable buyers. The browser extension is the right "edge" play. "Mossad level" is the quality bar, not the customer.
+
+---
+
+## 8. Realistic timeline (no fantasy dates)
+
+- **This week:** ship the overhaul (bug fix, consolidation, SEO, security, UI). Finish the cold-outreach list. Send first 10 emails.
+- **14 days:** first `$499` assessment sold and delivered. 3 discovery calls booked.
+- **45 days:** 1 installed pilot generating a CMMC PDF. 1 RPO/MSP partner conversation advanced. This is the real go/no-go.
+- **90-180 days:** first subscription contracts close (this is the honest length of a defense compliance sales cycle - your own primer says so).
+
+The product is not the question anymore. The only question is whether you will pick up the phone. Everything in this repo from here forward should serve that one act.

-## Lane details
-
-### Lane 1 — Bash validation
-
-- **Status:** merged on `main`.
-- **Feature commit:** `36dac6c` — `feat: add bash validation submodules — readOnlyValidation, destructiveCommandWarning, modeValidation, sedValidation, pathValidation, commandSemantics`
-- **Evidence:** branch-only diff adds `rust/crates/runtime/src/bash_validation.rs` and a `runtime::lib` export (`+1005` across 2 files).
-- **Main-branch reality:** `rust/crates/runtime/src/bash.rs` is still the active on-`main` implementation at **283 LOC**, with timeout/background/sandbox execution. `PermissionEnforcer::check_bash()` adds read-only gating on `main`, but the dedicated validation module is not landed.
-
-### Bash tool — upstream has 18 submodules, Rust has 1:
-
-- On `main`, this statement is still materially true.
-- Harness coverage proves bash execution and prompt escalation flows, but not the full upstream validation matrix.
-- The branch-only lane targets `readOnlyValidation`, `destructiveCommandWarning`, `modeValidation`, `sedValidation`, `pathValidation`, and `commandSemantics`.
-
-### Lane 2 — CI fix
-
-- **Status:** merged on `main`.
-- **Feature commit:** `89104eb` — `fix(sandbox): probe unshare capability instead of binary existence`
-- **Merge commit:** `f1969ce` — `Merge jobdori/fix-ci-sandbox: probe unshare capability for CI fix`
-- **Evidence:** `rust/crates/runtime/src/sandbox.rs` is **385 LOC** and now resolves sandbox support from actual `unshare` capability and container signals instead of assuming support from binary presence alone.
-- **Why it matters:** `.github/workflows/rust-ci.yml` runs `cargo fmt --all --check` and `cargo test -p rusty-claude-cli`; this lane removed a CI-specific sandbox assumption from runtime behavior.
-
-### Lane 3 — File-tool
-
-- **Status:** merged on `main`.
-- **Feature commit:** `284163b` — `feat(file_ops): add edge-case guards — binary detection, size limits, workspace boundary, symlink escape`
-- **Merge commit:** `a98f2b6` — `Merge jobdori/file-tool-edge-cases: binary detection, size limits, workspace boundary guards`
-- **Evidence:** `rust/crates/runtime/src/file_ops.rs` is **744 LOC** and now includes `MAX_READ_SIZE`, `MAX_WRITE_SIZE`, NUL-byte binary detection, and canonical workspace-boundary validation.
-- **Harness coverage:** `read_file_roundtrip`, `grep_chunk_assembly`, `write_file_allowed`, and `write_file_denied` are in the manifest and exercised by the clean-env harness.
-
-### File tools — harness-validated flows
-
-- `read_file_roundtrip` checks read-path execution and final synthesis.
-- `grep_chunk_assembly` checks chunked grep tool output handling.
-- `write_file_allowed` and `write_file_denied` validate both write success and permission denial.
-
-### Lane 4 — TaskRegistry
-
-- **Status:** merged on `main`.
-- **Feature commit:** `5ea138e` — `feat(runtime): add TaskRegistry — in-memory task lifecycle management`
-- **Merge commit:** `21a1e1d` — `Merge jobdori/task-runtime: TaskRegistry in-memory lifecycle management`
-- **Evidence:** `rust/crates/runtime/src/task_registry.rs` is **335 LOC** and provides `create`, `get`, `list`, `stop`, `update`, `output`, `append_output`, `set_status`, and `assign_team` over a thread-safe in-memory registry.
-- **Scope:** this lane replaces pure fixed-payload stub state with real runtime-backed task records, but it does not add external subprocess execution by itself.
-
-### Lane 5 — Task wiring
-
-- **Status:** merged on `main`.
-- **Feature commit:** `e8692e4` — `feat(tools): wire TaskRegistry into task tool dispatch`
-- **Merge commit:** `d994be6` — `Merge jobdori/task-registry-wiring: real TaskRegistry backing for all 6 task tools`
-- **Evidence:** `rust/crates/tools/src/lib.rs` dispatches `TaskCreate`, `TaskGet`, `TaskList`, `TaskStop`, `TaskUpdate`, and `TaskOutput` through `execute_tool()` and concrete `run_task_*` handlers.
-- **Current state:** task tools now expose real registry state on `main` via `global_task_registry()`.
-
-### Lane 6 — Team+Cron
-
-- **Status:** merged on `main`.
-- **Feature commit:** `c486ca6` — `feat(runtime+tools): TeamRegistry and CronRegistry — replace team/cron stubs`
-- **Merge commit:** `49653fe` — `Merge jobdori/team-cron-runtime: TeamRegistry + CronRegistry wired into tool dispatch`
-- **Evidence:** `rust/crates/runtime/src/team_cron_registry.rs` is **363 LOC** and adds thread-safe `TeamRegistry` and `CronRegistry`; `rust/crates/tools/src/lib.rs` wires `TeamCreate`, `TeamDelete`, `CronCreate`, `CronDelete`, and `CronList` into those registries.
-- **Current state:** team/cron tools now have in-memory lifecycle behavior on `main`; they still stop short of a real background scheduler or worker fleet.
-
-### Lane 7 — MCP lifecycle
-
-- **Status:** merged on `main`.
-- **Feature commit:** `730667f` — `feat(runtime+tools): McpToolRegistry — MCP lifecycle bridge for tool surface`
-- **Merge commit:** `cc0f92e` — `Merge jobdori/mcp-lifecycle: McpToolRegistry lifecycle bridge for all MCP tools`
-- **Evidence:** `rust/crates/runtime/src/mcp_tool_bridge.rs` is **406 LOC** and tracks server connection status, resource listing, resource reads, tool listing, tool dispatch acknowledgements, auth state, and disconnects.
-- **Wiring:** `rust/crates/tools/src/lib.rs` routes `ListMcpResources`, `ReadMcpResource`, `McpAuth`, and `MCP` into `global_mcp_registry()` handlers.
-- **Scope:** this lane replaces pure stub responses with a registry bridge on `main`; end-to-end MCP connection population and broader transport/runtime depth still depend on the wider MCP runtime (`mcp_stdio.rs`, `mcp_client.rs`, `mcp.rs`).
-
-### Lane 8 — LSP client
-
-- **Status:** merged on `main`.
-- **Feature commit:** `2d66503` — `feat(runtime+tools): LspRegistry — LSP client dispatch for tool surface`
-- **Merge commit:** `d7f0dc6` — `Merge jobdori/lsp-client: LspRegistry dispatch for all LSP tool actions`
-- **Evidence:** `rust/crates/runtime/src/lsp_client.rs` is **438 LOC** and models diagnostics, hover, definition, references, completion, symbols, and formatting across a stateful registry.
-- **Wiring:** the exposed `LSP` tool schema in `rust/crates/tools/src/lib.rs` currently enumerates `symbols`, `references`, `diagnostics`, `definition`, and `hover`, then routes requests through `registry.dispatch(action, path, line, character, query)`.
-- **Scope:** current parity is registry/dispatch-level; completion/format support exists in the registry model, but not as clearly exposed at the tool schema boundary, and actual external language-server process orchestration remains separate.
-
-### Lane 9 — Permission enforcement
-
-- **Status:** merged on `main`.
-- **Feature commit:** `66283f4` — `feat(runtime+tools): PermissionEnforcer — permission mode enforcement layer`
-- **Merge commit:** `336f820` — `Merge jobdori/permission-enforcement: PermissionEnforcer with workspace + bash enforcement`
-- **Evidence:** `rust/crates/runtime/src/permission_enforcer.rs` is **340 LOC** and adds tool gating, file write boundary checks, and bash read-only heuristics on top of `rust/crates/runtime/src/permissions.rs`.
-- **Wiring:** `rust/crates/tools/src/lib.rs` exposes `enforce_permission_check()` and carries per-tool `required_permission` values in tool specs.
-
-### Permission enforcement across tool paths
-
-- Harness scenarios validate `write_file_denied`, `bash_permission_prompt_approved`, and `bash_permission_prompt_denied`.
-- `PermissionEnforcer::check()` delegates to `PermissionPolicy::authorize()` and returns structured allow/deny results.
-- `check_file_write()` enforces workspace boundaries and read-only denial; `check_bash()` denies mutating commands in read-only mode and blocks prompt-mode bash without confirmation.
-
-## Tool Surface: 40 exposed tool specs on `main`
-
-- `mvp_tool_specs()` in `rust/crates/tools/src/lib.rs` exposes **40** tool specs.
-- Core execution is present for `bash`, `read_file`, `write_file`, `edit_file`, `glob_search`, and `grep_search`.
-- Existing product tools in `mvp_tool_specs()` include `WebFetch`, `WebSearch`, `TodoWrite`, `Skill`, `Agent`, `ToolSearch`, `NotebookEdit`, `Sleep`, `SendUserMessage`, `Config`, `EnterPlanMode`, `ExitPlanMode`, `StructuredOutput`, `REPL`, and `PowerShell`.
-- The 9-lane push replaced pure fixed-payload stubs for `Task*`, `Team*`, `Cron*`, `LSP`, and MCP tools with registry-backed handlers on `main`.
-- `Brief` is handled as an execution alias in `execute_tool()`, but it is not a separately exposed tool spec in `mvp_tool_specs()`.
-
-### Still limited or intentionally shallow
-
-- `AskUserQuestion` still returns a pending response payload rather than real interactive UI wiring.
-- `RemoteTrigger` remains a stub response.
-- `TestingPermission` remains test-only.
-- Task, team, cron, MCP, and LSP are no longer just fixed-payload stubs in `execute_tool()`, but several remain registry-backed approximations rather than full external-runtime integrations.
-- Bash deep validation remains branch-only until `36dac6c` is merged.
-
-## Reconciled from the older PARITY checklist
-
-- [x] Path traversal prevention (symlink following, `../` escapes)
-- [x] Size limits on read/write
-- [x] Binary file detection
-- [x] Permission mode enforcement (read-only vs workspace-write)
-- [x] Config merge precedence (user > project > local) — `ConfigLoader::discover()` loads user → project → local, and `loads_and_merges_claude_code_config_files_by_precedence()` verifies the merge order.
-- [x] Plugin install/enable/disable/uninstall flow — `/plugin` slash handling in `rust/crates/commands/src/lib.rs` delegates to `PluginManager::{install, enable, disable, uninstall}` in `rust/crates/plugins/src/lib.rs`.
-- [x] No `#[ignore]` tests hiding failures — `grep` over `rust/**/*.rs` found 0 ignored tests.
-
-## Still open
-
-- [ ] End-to-end MCP runtime lifecycle beyond the registry bridge now on `main`
-- [x] Output truncation (large stdout/file content)
-- [ ] Session compaction behavior matching
-- [ ] Token counting / cost tracking accuracy
-- [x] Bash validation lane merged onto `main`
-- [ ] CI green on every commit
-
-## Migration Readiness
-
-- [x] `PARITY.md` maintained and honest
-- [x] 9 requested lanes documented with commit hashes and current status
-- [x] All 9 requested lanes landed on `main` (`bash-validation` is still branch-only)
-- [x] No `#[ignore]` tests hiding failures
-- [ ] CI green on every commit
-- [x] Codebase shape clean enough for handoff documentation

-# Claw Code Philosophy
-
-## Stop Staring at the Files
-
-If you only look at the generated files in this repository, you are looking at the wrong layer.
-
-The Python rewrite was a byproduct. The Rust rewrite was also a byproduct. The real thing worth studying is the **system that produced them**: a clawhip-based coordination loop where humans give direction and autonomous claws execute the work.
-
-Claw Code is not just a codebase. It is a public demonstration of what happens when:
-
-- a human provides clear direction,
-- multiple coding agents coordinate in parallel,
-- notification routing is pushed out of the agent context window,
-- planning, execution, review, and retry loops are automated,
-- and the human does **not** sit in a terminal micromanaging every step.
-
-## The Human Interface Is Discord
-
-The important interface here is not tmux, Vim, SSH, or a terminal multiplexer.
-
-The real human interface is a Discord channel.
-
-A person can type a sentence from a phone, walk away, sleep, or do something else. The claws read the directive, break it into tasks, assign roles, write code, run tests, argue over failures, recover, and push when the work passes.
-
-That is the philosophy: **humans set direction; claws perform the labor.**
-
-## The Three-Part System
-
-### 1. OmX (`oh-my-codex`)
-[oh-my-codex](https://github.com/Yeachan-Heo/oh-my-codex) provides the workflow layer.
-
-It turns short directives into structured execution:
-- planning keywords
-- execution modes
-- persistent verification loops
-- parallel multi-agent workflows
-
-This is the layer that converts a sentence into a repeatable work protocol.
-
-### 2. clawhip
-[clawhip](https://github.com/Yeachan-Heo/clawhip) is the event and notification router.
-
-It watches:
-- git commits
-- tmux sessions
-- GitHub issues and PRs
-- agent lifecycle events
-- channel delivery
-
-Its job is to keep monitoring and delivery **outside** the coding agent's context window so the agents can stay focused on implementation instead of status formatting and notification routing.
-
-### 3. OmO (`oh-my-openagent`)
-[oh-my-openagent](https://github.com/code-yeongyu/oh-my-openagent) handles multi-agent coordination.
-
-This is where planning, handoffs, disagreement resolution, and verification loops happen across agents.
-
-When Architect, Executor, and Reviewer disagree, OmO provides the structure for that loop to converge instead of collapse.
-
-## The Real Bottleneck Changed
-
-The bottleneck is no longer typing speed.
-
-When agent systems can rebuild a codebase in hours, the scarce resource becomes:
-- architectural clarity
-- task decomposition
-- judgment
-- taste
-- conviction about what is worth building
-- knowing which parts can be parallelized and which parts must stay constrained
-
-A fast agent team does not remove the need for thinking. It makes clear thinking even more valuable.
-
-## What Claw Code Demonstrates
-
-Claw Code demonstrates that a repository can be:
-
-- **autonomously built in public**
-- coordinated by claws/lobsters rather than human pair-programming alone
-- operated through a chat interface
-- continuously improved by structured planning/execution/review loops
-- maintained as a showcase of the coordination layer, not just the output files
-
-The code is evidence.
-The coordination system is the product lesson.
-
-## What Still Matters
-
-As coding intelligence gets cheaper and more available, the durable differentiators are not raw coding output.
-
-What still matters:
-- product taste
-- direction
-- system design
-- human trust
-- operational stability
-- judgment about what to build next
-
-In that world, the job of the human is not to out-type the machine.
-The job of the human is to decide what deserves to exist.
-
-## Short Version
-
-**Claw Code is a demo of autonomous software development.**
-
-Humans provide direction.
-Claws coordinate, build, test, recover, and push.
-The repository is the artifact.
-The philosophy is the system behind it.
-

-# Claw Code
-
-
-
-Claw Code is the public Rust implementation of the `claw` CLI agent harness.
-The canonical implementation lives in [`rust/`](./rust), and the current source of truth for this repository is **ultraworkers/claw-code**.
-
-> [!IMPORTANT]
-> Start with [`USAGE.md`](./USAGE.md) for build, auth, CLI, session, and parity-harness workflows. Make `claw doctor` your first health check after building, use [`rust/README.md`](./rust/README.md) for crate-level details, read [`PARITY.md`](./PARITY.md) for the current Rust-port checkpoint, and see [`docs/container.md`](./docs/container.md) for the container-first workflow.

-# Clawable Coding Harness Roadmap
-
-## Goal
-
-Turn claw-code into the most **clawable** coding harness:
-- no human-first terminal assumptions
-- no fragile prompt injection timing
-- no opaque session state
-- no hidden plugin or MCP failures
-- no manual babysitting for routine recovery
-
-This roadmap assumes the primary users are **claws wired through hooks, plugins, sessions, and channel events**.
-
-## Definition of "clawable"
-
-A clawable harness is:
-- deterministic to start
-- machine-readable in state and failure modes
-- recoverable without a human watching the terminal
-- branch/test/worktree aware
-- plugin/MCP lifecycle aware
-- event-first, not log-first
-- capable of autonomous next-step execution
-
-## Current Pain Points
-
-### 1. Session boot is fragile
-- trust prompts can block TUI startup
-- prompts can land in the shell instead of the coding agent
-- "session exists" does not mean "session is ready"
-
-### 2. Truth is split across layers
-- tmux state
-- clawhip event stream
-- git/worktree state
-- test state
-- gateway/plugin/MCP runtime state
-
-### 3. Events are too log-shaped
-- claws currently infer too much from noisy text
-- important states are not normalized into machine-readable events
-
-### 4. Recovery loops are too manual
-- restart worker
-- accept trust prompt
-- re-inject prompt
-- detect stale branch
-- retry failed startup
-- classify infra vs code failures manually
-
-### 5. Branch freshness is not enforced enough
-- side branches can miss already-landed main fixes
-- broad test failures can be stale-branch noise instead of real regressions
-
-### 6. Plugin/MCP failures are under-classified
-- startup failures, handshake failures, config errors, partial startup, and degraded mode are not exposed cleanly enough
-
-### 7. Human UX still leaks into claw workflows
-- too much depends on terminal/TUI behavior instead of explicit agent state transitions and control APIs
-
-## Product Principles
-
-1. **State machine first** — every worker has explicit lifecycle states.
-2. **Events over scraped prose** — channel output should be derived from typed events.
-3. **Recovery before escalation** — known failure modes should auto-heal once before asking for help.
-4. **Branch freshness before blame** — detect stale branches before treating red tests as new regressions.
-5. **Partial success is first-class** — e.g. MCP startup can succeed for some servers and fail for others, with structured degraded-mode reporting.
-6. **Terminal is transport, not truth** — tmux/TUI may remain implementation details, but orchestration state must live above them.
-7. **Policy is executable** — merge, retry, rebase, stale cleanup, and escalation rules should be machine-enforced.
-
-## Roadmap
-
-## Phase 1 — Reliable Worker Boot
-
-### 1. Ready-handshake lifecycle for coding workers
-Add explicit states:
-- `spawning`
-- `trust_required`
-- `ready_for_prompt`
-- `prompt_accepted`
-- `running`
-- `blocked`
-- `finished`
-- `failed`
-
-Acceptance:
-- prompts are never sent before `ready_for_prompt`
-- trust prompt state is detectable and emitted
-- shell misdelivery becomes detectable as a first-class failure state
-
-### 2. Trust prompt resolver
-Add allowlisted auto-trust behavior for known repos/worktrees.
-
-Acceptance:
-- trusted repos auto-clear trust prompts
-- events emitted for `trust_required` and `trust_resolved`
-- non-allowlisted repos remain gated
-
-### 3. Structured session control API
-Provide machine control above tmux:
-- create worker
-- await ready
-- send task
-- fetch state
-- fetch last error
-- restart worker
-- terminate worker
-
-Acceptance:
-- a claw can operate a coding worker without raw send-keys as the primary control plane
-
-## Phase 2 — Event-Native Clawhip Integration
-
-### 4. Canonical lane event schema
-Define typed events such as:
-- `lane.started`
-- `lane.ready`
-- `lane.prompt_misdelivery`
-- `lane.blocked`
-- `lane.red`
-- `lane.green`
-- `lane.commit.created`
-- `lane.pr.opened`
-- `lane.merge.ready`
-- `lane.finished`
-- `lane.failed`
-- `branch.stale_against_main`
-
-Acceptance:
-- clawhip consumes typed lane events
-- Discord summaries are rendered from structured events instead of pane scraping alone
-
-### 5. Failure taxonomy
-Normalize failure classes:
-- `prompt_delivery`
-- `trust_gate`
-- `branch_divergence`
-- `compile`
-- `test`
-- `plugin_startup`
-- `mcp_startup`
-- `mcp_handshake`
-- `gateway_routing`
-- `tool_runtime`
-- `infra`
-
-Acceptance:
-- blockers are machine-classified
-- dashboards and retry policies can branch on failure type
-
-### 6. Actionable summary compression
-Collapse noisy event streams into:
-- current phase
-- last successful checkpoint
-- current blocker
-- recommended next recovery action
-
-Acceptance:
-- channel status updates stay short and machine-grounded
-- claws stop inferring state from raw build spam
-
-## Phase 3 — Branch/Test Awareness and Auto-Recovery
-
-### 7. Stale-branch detection before broad verification
-Before broad test runs, compare current branch to `main` and detect if known fixes are missing.
-
-Acceptance:
-- emit `branch.stale_against_main`
-- suggest or auto-run rebase/merge-forward according to policy
-- avoid misclassifying stale-branch failures as new regressions
-
-### 8. Recovery recipes for common failures
-Encode known automatic recoveries for:
-- trust prompt unresolved
-- prompt delivered to shell
-- stale branch
-- compile red after cross-crate refactor
-- MCP startup handshake failure
-- partial plugin startup
-
-Acceptance:
-- one automatic recovery attempt occurs before escalation
-- the attempted recovery is itself emitted as structured event data
-
-### 9. Green-ness contract
-Workers should distinguish:
-- targeted tests green
-- package green
-- workspace green
-- merge-ready green
-
-Acceptance:
-- no more ambiguous "tests passed" messaging
-- merge policy can require the correct green level for the lane type
-
-## Phase 4 — Claws-First Task Execution
-
-### 10. Typed task packet format
-Define a structured task packet with fields like:
-- objective
-- scope
-- repo/worktree
-- branch policy
-- acceptance tests
-- commit policy
-- reporting contract
-- escalation policy
-
-Acceptance:
-- claws can dispatch work without relying on long natural-language prompt blobs alone
-- task packets can be logged, retried, and transformed safely
-
-### 11. Policy engine for autonomous coding
-Encode automation rules such as:
-- if green + scoped diff + review passed -> merge to dev
-- if stale branch -> merge-forward before broad tests
-- if startup blocked -> recover once, then escalate
-- if lane completed -> emit closeout and cleanup session
-
-Acceptance:
-- doctrine moves from chat instructions into executable rules
-
-### 12. Claw-native dashboards / lane board
-Expose a machine-readable board of:
-- repos
-- active claws
-- worktrees
-- branch freshness
-- red/green state
-- current blocker
-- merge readiness
-- last meaningful event
-
-Acceptance:
-- claws can query status directly
-- human-facing views become a rendering layer, not the source of truth
-
-## Phase 5 — Plugin and MCP Lifecycle Maturity
-
-### 13. First-class plugin/MCP lifecycle contract
-Each plugin/MCP integration should expose:
-- config validation contract
-- startup healthcheck
-- discovery result
-- degraded-mode behavior
-- shutdown/cleanup contract
-
-Acceptance:
-- partial-startup and per-server failures are reported structurally
-- successful servers remain usable even when one server fails
-
-### 14. MCP end-to-end lifecycle parity
-Close gaps from:
-- config load
-- server registration
-- spawn/connect
-- initialize handshake
-- tool/resource discovery
-- invocation path
-- error surfacing
-- shutdown/cleanup
-
-Acceptance:
-- parity harness and runtime tests cover healthy and degraded startup cases
-- broken servers are surfaced as structured failures, not opaque warnings
-
-## Immediate Backlog (from current real pain)
-
-Priority order: P0 = blocks CI/green state, P1 = blocks integration wiring, P2 = clawability hardening, P3 = swarm-efficiency improvements.
-
-**P0 — Fix first (CI reliability)**
-1. Isolate `render_diff_report` tests into tmpdir — **done**: `render_diff_report_for()` tests run in temp git repos instead of the live working tree, and targeted `cargo test -p rusty-claude-cli render_diff_report -- --nocapture` now stays green during branch/worktree activity
-2. Expand GitHub CI from single-crate coverage to workspace-grade verification — **done**: `.github/workflows/rust-ci.yml` now runs `cargo test --workspace` plus fmt/clippy at the workspace level
-3. Add release-grade binary workflow — **done**: `.github/workflows/release.yml` now builds tagged Rust release artifacts for the CLI
-4. Add container-first test/run docs — **done**: `Containerfile` + `docs/container.md` document the canonical Docker/Podman workflow for build, bind-mount, and `cargo test --workspace` usage
-5. Surface `doctor` / preflight diagnostics in onboarding docs and help — **done**: README + USAGE now put `claw doctor` / `/doctor` in the first-run path and point at the built-in preflight report
-6. Automate branding/source-of-truth residue checks in CI — **done**: `.github/scripts/check_doc_source_of_truth.py` and the `doc-source-of-truth` CI job now block stale repo/org/invite residue in tracked docs and metadata
-7. Eliminate warning spam from first-run help/build path — **done**: current `cargo run -q -p rusty-claude-cli -- --help` renders clean help output without a warning wall before the product surface
-8. Promote `doctor` from slash-only to top-level CLI entrypoint — **done**: `claw doctor` is now a local shell entrypoint with regression coverage for direct help and health-report output
-9. Make machine-readable status commands actually machine-readable — **done**: `claw --output-format json status` and `claw --output-format json sandbox` now emit structured JSON snapshots instead of prose tables
-10. Unify legacy config/skill namespaces in user-facing output — **done**: skills/help JSON/text output now present `.claw` as the canonical namespace and collapse legacy roots behind `.claw`-shaped source ids/labels
-11. Honor JSON output on inventory commands like `skills` and `mcp` — **done**: direct CLI inventory commands now honor `--output-format json` with structured payloads for both skills and MCP inventory
-12. Audit `--output-format` contract across the whole CLI surface — **done**: direct CLI commands now honor deterministic JSON/text handling across help/version/status/sandbox/agents/mcp/skills/bootstrap-plan/system-prompt/init/doctor, with regression coverage in `output_format_contract.rs` and resumed `/status` JSON coverage
-
-**P1 — Next (integration wiring, unblocks verification)**
-2. Add cross-module integration tests — **done**: 12 integration tests covering worker→recovery→policy, stale_branch→policy, green_contract→policy, reconciliation flows
-3. Wire lane-completion emitter — **done**: `lane_completion` module with `detect_lane_completion()` auto-sets `LaneContext::completed` from session-finished + tests-green + push-complete → policy closeout
-4. Wire `SummaryCompressor` into the lane event pipeline — **done**: `compress_summary_text()` feeds into `LaneEvent::Finished` detail field in `tools/src/lib.rs`
-
-**P2 — Clawability hardening (original backlog)**
-5. Worker readiness handshake + trust resolution — **done**: `WorkerStatus` state machine with `Spawning` → `TrustRequired` → `ReadyForPrompt` → `PromptAccepted` → `Running` lifecycle, `trust_auto_resolve` + `trust_gate_cleared` gating
-6. Prompt misdelivery detection and recovery — **done**: `prompt_delivery_attempts` counter, `PromptMisdelivery` event detection, `auto_recover_prompt_misdelivery` + `replay_prompt` recovery arm
-7. Canonical lane event schema in clawhip — **done**: `LaneEvent` enum with `Started/Blocked/Failed/Finished` variants, `LaneEvent::new()` typed constructor, `tools/src/lib.rs` integration
-8. Failure taxonomy + blocker normalization — **done**: `WorkerFailureKind` enum (`TrustGate/PromptDelivery/Protocol/Provider`), `FailureScenario::from_worker_failure_kind()` bridge to recovery recipes
-9. Stale-branch detection before workspace tests — **done**: `stale_branch.rs` module with freshness detection, behind/ahead metrics, policy integration
-10. MCP structured degraded-startup reporting — **done**: `McpManager` degraded-startup reporting (+183 lines in `mcp_stdio.rs`), failed server classification (startup/handshake/config/partial), structured `failed_servers` + `recovery_recommendations` in tool output
-11. Structured task packet format — **done**: `task_packet.rs` module with `TaskPacket` struct, validation, serialization, `TaskScope` resolution (workspace/module/single-file/custom), integrated into `tools/src/lib.rs`
-12. Lane board / machine-readable status API — **done**: Lane completion hardening + `LaneContext::completed` auto-detection + MCP degraded reporting surface machine-readable state
-13. **Session completion failure classification** — **done**: `WorkerFailureKind::Provider` + `observe_completion()` + recovery recipe bridge landed
-14. **Config merge validation gap** — **done**: `config.rs` hook validation before deep-merge (+56 lines), malformed entries fail with source-path context instead of merged parse errors
-15. **MCP manager discovery flaky test** — **done**: `manager_discovery_report_keeps_healthy_servers_when_one_server_fails` now runs as a normal workspace test again after repeated stable passes, so degraded-startup coverage is no longer hidden behind `#[ignore]`
-
-16. **Commit provenance / worktree-aware push events** — **done**: `LaneCommitProvenance` now carries branch/worktree/canonical-commit/supersession metadata in lane events, and `dedupe_superseded_commit_events()` is applied before agent manifests are written so superseded commit events collapse to the latest canonical lineage
-17. **Orphaned module integration audit** — **done**: `runtime` now keeps `session_control` and `trust_resolver` behind `#[cfg(test)]` until they are wired into a real non-test execution path, so normal builds no longer advertise dead clawability surface area.
-18. **Context-window preflight gap** — **done**: provider request sizing now emits `context_window_blocked` before oversized requests leave the process, using a model-context registry instead of the old naive max-token heuristic.
-19. **Subcommand help falls through into runtime/API path** — **done**: `claw doctor --help`, `claw status --help`, `claw sandbox --help`, and nested `mcp`/`skills` help are now intercepted locally without runtime/provider startup, with regression tests covering the direct CLI paths.
-20. **Session state classification gap (working vs blocked vs finished vs truly stale)** — **done**: agent manifests now derive machine states such as `working`, `blocked_background_job`, `blocked_merge_conflict`, `degraded_mcp`, `interrupted_transport`, `finished_pending_report`, and `finished_cleanable`, and terminal-state persistence records commit provenance plus derived state so downstream monitoring can distinguish quiet progress from truly idle sessions.
-21. **Resumed `/status` JSON parity gap** — dogfooding shows fresh `claw status --output-format json` now emits structured JSON, but resumed slash-command status still leaks through a text-shaped path in at least one dispatch path. Local CI-equivalent repro fails `rust/crates/rusty-claude-cli/tests/resume_slash_commands.rs::resumed_status_command_emits_structured_json_when_requested` with `expected value at line 1 column 1`, so resumed automation can receive text where JSON was explicitly requested. **Action:** unify fresh vs resumed `/status` rendering through one output-format contract and add regression coverage so resumed JSON output is guaranteed valid.
-22. **Opaque failure surface for session/runtime crashes** — repeated dogfood-facing failures can currently collapse to generic wrappers like `Something went wrong while processing your request. Please try again, or use /new to start a fresh session.` without exposing whether the fault was provider auth, session corruption, slash-command dispatch, render failure, or transport/runtime panic. This blocks fast self-recovery and turns actionable clawability bugs into blind retries. **Action:** preserve a short user-safe failure class (`provider_auth`, `session_load`, `command_dispatch`, `render`, `runtime_panic`, etc.), attach a local trace/session id, and ensure operators can jump from the chat-visible error to the exact failure log quickly.
-23. **`doctor --output-format json` check-level structure gap** — **done**: `claw doctor --output-format json` now keeps the human-readable `message`/`report` while also emitting structured per-check diagnostics (`name`, `status`, `summary`, `details`, plus typed fields like workspace paths and sandbox fallback data), with regression coverage in `output_format_contract.rs`.
-24. **Plugin lifecycle init/shutdown test flakes under workspace-parallel execution** — dogfooding surfaced that `build_runtime_runs_plugin_lifecycle_init_and_shutdown` can fail under `cargo test --workspace` while passing in isolation because sibling tests race on tempdir-backed shell init script paths. This is test brittleness rather than a code-path regression, but it still destabilizes CI confidence and wastes diagnosis cycles. **Action:** isolate temp resources per test robustly (unique dirs + no shared cwd assumptions), audit cleanup timing, and add a regression guard so the plugin lifecycle test remains stable under parallel workspace execution.
-26. **Resumed local-command JSON parity gap** — **done**: direct `claw --output-format json` already had structured renderers for `sandbox`, `mcp`, `skills`, `version`, and `init`, but resumed `claw --output-format json --resume /…` paths still fell back to prose because resumed slash dispatch only emitted JSON for `/status`. Resumed `/sandbox`, `/mcp`, `/skills`, `/version`, and `/init` now reuse the same JSON envelopes as their direct CLI counterparts, with regression coverage in `rust/crates/rusty-claude-cli/tests/resume_slash_commands.rs` and `rust/crates/rusty-claude-cli/tests/output_format_contract.rs`.
-
-41. **Phantom completions root cause: global session store has no per-worktree isolation** —
-
- **Root cause.** The session store under `~/.local/share/opencode` is global to the host. Every `opencode serve` instance — including the parallel lane workers spawned per worktree — reads and writes the same on-disk session directory. Sessions are keyed only by id and timestamp, not by the workspace they were created in, so there is no structural barrier between a session created in worktree `/tmp/b4-phantom-diag` and one created in `/tmp/b4-omc-flat`. Whichever serve instance picks up a given session id can drive it from whatever CWD that serve happens to be running in.
-
- **Impact.** Parallel lanes silently cross wires. A lane reports a clean run — file edits, builds, tests — and the orchestrator marks the lane green, but the writes were applied against another worktree's CWD because a sibling `opencode serve` won the session race. The originating worktree shows no diff, the *other* worktree gains unexplained edits, and downstream consumers (clawhip lane events, PR pushes, merge gates) treat the empty originator as a successful no-op. These are the "phantom completions" we keep chasing: success messaging without any landed changes in the lane that claimed them, plus stray edits in unrelated lanes whose own runs never touched those files. Because the report path is happy, retries and recovery recipes never fire, so the lane silently wedges until a human notices the diff is empty.
-
- **Proposed fix.** Bind every session to its workspace root + branch at creation time and refuse to drive it from any other CWD.
-
- - At session creation, capture the canonical workspace root (resolved git worktree path) and the active branch and persist them on the session record.
- - On every load (`opencode serve`, slash-command resume, lane recovery), validate that the current process CWD matches the persisted workspace root before any tool with side effects (file_ops, bash, git) is allowed to run. Mismatches surface as a typed `WorkspaceMismatch` failure class instead of silently writing to the wrong tree.
- - Namespace the on-disk session path under the workspace fingerprint (e.g. `//`) so two parallel `opencode serve` instances physically cannot collide on the same session id.
- - Forks inherit the parent's workspace root by default; an explicit re-bind is required to move a session to a new worktree, and that re-bind is itself recorded as a structured event so the orchestrator can audit cross-worktree handoffs.
- - Surface a `branch.workspace_mismatch` lane event so clawhip stops counting wrong-CWD writes as lane completions.
-
- **Status.** A `workspace_root` field has been added to `Session` in `rust/crates/runtime/src/session.rs` (with builder, accessor, JSON + JSONL round-trip, fork inheritance, and given/when/then test coverage in `persists_workspace_root_round_trip_and_forks_inherit_it`). The CWD validation, the namespaced on-disk path, and the `branch.workspace_mismatch` lane event are still outstanding and tracked under this item.
-
-**P3 — Swarm efficiency**
-13. Swarm branch-lock protocol — **done**: `branch_lock::detect_branch_lock_collisions()` now detects same-branch/same-scope and nested-module collisions before parallel lanes drift into duplicate implementation
-14. Commit provenance / worktree-aware push events — **done**: lane event provenance now includes branch/worktree/superseded/canonical lineage metadata, and manifest persistence de-dupes superseded commit events before downstream consumers render them
-
-## Suggested Session Split
-
-### Session A — worker boot protocol
-Focus:
-- trust prompt detection
-- ready-for-prompt handshake
-- prompt misdelivery detection
-
-### Session B — clawhip lane events
-Focus:
-- canonical lane event schema
-- failure taxonomy
-- summary compression
-
-### Session C — branch/test intelligence
-Focus:
-- stale-branch detection
-- green-level contract
-- recovery recipes
-
-### Session D — MCP lifecycle hardening
-Focus:
-- startup/handshake reliability
-- structured failed server reporting
-- degraded-mode runtime behavior
-- lifecycle tests/harness coverage
-
-### Session E — typed task packets + policy engine
-Focus:
-- structured task format
-- retry/merge/escalation rules
-- autonomous lane closure behavior
-
-## MVP Success Criteria
-
-We should consider claw-code materially more clawable when:
-- a claw can start a worker and know with certainty when it is ready
-- claws no longer accidentally type tasks into the shell
-- stale-branch failures are identified before they waste debugging time
-- clawhip reports machine states, not just tmux prose
-- MCP/plugin startup failures are classified and surfaced cleanly
-- a coding lane can self-recover from common startup and branch issues without human babysitting
-
-## Short Version
-
-claw-code should evolve from:
-- a CLI a human can also drive
-
-to:
-- a **claw-native execution runtime**
-- an **event-native orchestration substrate**
-- a **plugin/hook-first autonomous coding harness**

-# Claw Code Usage
-
-This guide covers the current Rust workspace under `rust/` and the `claw` CLI binary. If you are brand new, make the doctor health check your first run: start `claw`, then run `/doctor`.
-
-## Quick-start health check
-
-Run this before prompts, sessions, or automation:
-
-```bash
-cd rust
-cargo build --workspace
-./target/debug/claw
-# first command inside the REPL
-/doctor
-```
-
-`/doctor` is the built-in setup and preflight diagnostic. Once you have a saved session, you can rerun it with `./target/debug/claw --resume latest /doctor`.
-
-## Prerequisites
-
-- Rust toolchain with `cargo`
-- One of:
- - `ANTHROPIC_API_KEY` for direct API access
- - `claw login` for OAuth-based auth
-- Optional: `ANTHROPIC_BASE_URL` when targeting a proxy or local service
-
-## Install / build the workspace
-
-```bash
-cd rust
-cargo build --workspace
-```
-
-The CLI binary is available at `rust/target/debug/claw` after a debug build. Make the doctor check above your first post-build step.
-
-## Quick start
-
-### First-run doctor check
-
-```bash
-cd rust
-./target/debug/claw
-/doctor
-```
-
-### Interactive REPL
-
-```bash
-cd rust
-./target/debug/claw
-```
-
-### One-shot prompt
-
-```bash
-cd rust
-./target/debug/claw prompt "summarize this repository"
-```
-
-### Shorthand prompt mode
-
-```bash
-cd rust
-./target/debug/claw "explain rust/crates/runtime/src/lib.rs"
-```
-
-### JSON output for scripting
-
-```bash
-cd rust
-./target/debug/claw --output-format json prompt "status"
-```
-
-## Model and permission controls
-
-```bash
-cd rust
-./target/debug/claw --model sonnet prompt "review this diff"
-./target/debug/claw --permission-mode read-only prompt "summarize Cargo.toml"
-./target/debug/claw --permission-mode workspace-write prompt "update README.md"
-./target/debug/claw --allowedTools read,glob "inspect the runtime crate"
-```
-
-Supported permission modes:
-
-- `read-only`
-- `workspace-write`
-- `danger-full-access`
-
-Model aliases currently supported by the CLI:
-
-- `opus` → `claude-opus-4-6`
-- `sonnet` → `claude-sonnet-4-6`
-- `haiku` → `claude-haiku-4-5-20251213`
-
-## Authentication
-
-### API key
-
-```bash
-export ANTHROPIC_API_KEY="sk-ant-..."
-```
-
-### OAuth
-
-```bash
-cd rust
-./target/debug/claw login
-./target/debug/claw logout
-```
-
-## Local Models
-
-`claw` can talk to local servers and provider gateways through either Anthropic-compatible or OpenAI-compatible endpoints. Use `ANTHROPIC_BASE_URL` with `ANTHROPIC_AUTH_TOKEN` for Anthropic-compatible services, or `OPENAI_BASE_URL` with `OPENAI_API_KEY` for OpenAI-compatible services. OAuth is Anthropic-only, so when `OPENAI_BASE_URL` is set you should use API-key style auth instead of `claw login`.
-
-### Anthropic-compatible endpoint
-
-```bash
-export ANTHROPIC_BASE_URL="http://127.0.0.1:8080"
-export ANTHROPIC_AUTH_TOKEN="local-dev-token"
-
-cd rust
-./target/debug/claw --model "claude-sonnet-4-6" prompt "reply with the word ready"
-```
-
-### OpenAI-compatible endpoint
-
-```bash
-export OPENAI_BASE_URL="http://127.0.0.1:8000/v1"
-export OPENAI_API_KEY="local-dev-token"
-
-cd rust
-./target/debug/claw --model "qwen2.5-coder" prompt "reply with the word ready"
-```
-
-### Ollama
-
-```bash
-export OPENAI_BASE_URL="http://127.0.0.1:11434/v1"
-unset OPENAI_API_KEY
-
-cd rust
-./target/debug/claw --model "llama3.2" prompt "summarize this repository in one sentence"
-```
-
-### OpenRouter
-
-```bash
-export OPENAI_BASE_URL="https://openrouter.ai/api/v1"
-export OPENAI_API_KEY="sk-or-v1-..."
-
-cd rust
-./target/debug/claw --model "openai/gpt-4.1-mini" prompt "summarize this repository in one sentence"
-```
-
-## Supported Providers & Models
-
-`claw` has three built-in provider backends. The provider is selected automatically based on the model name, falling back to whichever credential is present in the environment.
-
-### Provider matrix
-
-| Provider | Protocol | Auth env var(s) | Base URL env var | Default base URL |
-|---|---|---|---|---|
-| **Anthropic** (direct) | Anthropic Messages API | `ANTHROPIC_API_KEY` or `ANTHROPIC_AUTH_TOKEN` or OAuth (`claw login`) | `ANTHROPIC_BASE_URL` | `https://api.anthropic.com` |
-| **xAI** | OpenAI-compatible | `XAI_API_KEY` | `XAI_BASE_URL` | `https://api.x.ai/v1` |
-| **OpenAI-compatible** | OpenAI Chat Completions | `OPENAI_API_KEY` | `OPENAI_BASE_URL` | `https://api.openai.com/v1` |
-
-The OpenAI-compatible backend also serves as the gateway for **OpenRouter**, **Ollama**, and any other service that speaks the OpenAI `/v1/chat/completions` wire format — just point `OPENAI_BASE_URL` at the service.
-
-### Tested models and aliases
-
-These are the models registered in the built-in alias table with known token limits:
-
-| Alias | Resolved model name | Provider | Max output tokens | Context window |
-|---|---|---|---|---|
-| `opus` | `claude-opus-4-6` | Anthropic | 32 000 | 200 000 |
-| `sonnet` | `claude-sonnet-4-6` | Anthropic | 64 000 | 200 000 |
-| `haiku` | `claude-haiku-4-5-20251213` | Anthropic | 64 000 | 200 000 |
-| `grok` / `grok-3` | `grok-3` | xAI | 64 000 | 131 072 |
-| `grok-mini` / `grok-3-mini` | `grok-3-mini` | xAI | 64 000 | 131 072 |
-| `grok-2` | `grok-2` | xAI | — | — |
-
-Any model name that does not match an alias is passed through verbatim. This is how you use OpenRouter model slugs (`openai/gpt-4.1-mini`), Ollama tags (`llama3.2`), or full Anthropic model IDs (`claude-sonnet-4-20250514`).
-
-### User-defined aliases
-
-You can add custom aliases in any settings file (`~/.claw/settings.json`, `.claw/settings.json`, or `.claw/settings.local.json`):
-
-```json
-{
- "aliases": {
- "fast": "claude-haiku-4-5-20251213",
- "smart": "claude-opus-4-6",
- "cheap": "grok-3-mini"
- }
-}
-```
-
-Local project settings override user-level settings. Aliases resolve through the built-in table, so `"fast": "haiku"` also works.
-
-### How provider detection works
-
-1. If the resolved model name starts with `claude` → Anthropic.
-2. If it starts with `grok` → xAI.
-3. Otherwise, `claw` checks which credential is set: `ANTHROPIC_API_KEY`/`ANTHROPIC_AUTH_TOKEN` first, then `OPENAI_API_KEY`, then `XAI_API_KEY`.
-4. If nothing matches, it defaults to Anthropic.
-
-## FAQ
-
-### What about Codex?
-
-The name "codex" appears in the Claw Code ecosystem but it does **not** refer to OpenAI Codex (the code-generation model). Here is what it means in this project:
-
-- **`oh-my-codex` (OmX)** is the workflow and plugin layer that sits on top of `claw`. It provides planning modes, parallel multi-agent execution, notification routing, and other automation features. See [PHILOSOPHY.md](./PHILOSOPHY.md) and the [oh-my-codex repo](https://github.com/Yeachan-Heo/oh-my-codex).
-- **`.codex/` directories** (e.g. `.codex/skills`, `.codex/agents`, `.codex/commands`) are legacy lookup paths that `claw` still scans alongside the primary `.claw/` directories.
-- **`CODEX_HOME`** is an optional environment variable that points to a custom root for user-level skill and command lookups.
-
-`claw` does **not** support OpenAI Codex sessions, the Codex CLI, or Codex session import/export. If you need to use OpenAI models (like GPT-4.1), configure the OpenAI-compatible provider as shown above in the [OpenAI-compatible endpoint](#openai-compatible-endpoint) and [OpenRouter](#openrouter) sections.
-
-## HTTP proxy support
-
-`claw` honours the standard `HTTP_PROXY`, `HTTPS_PROXY`, and `NO_PROXY` environment variables (both upper- and lower-case spellings are accepted) when issuing outbound requests to Anthropic, OpenAI-, and xAI-compatible endpoints. Set them before launching the CLI and the underlying `reqwest` client will be configured automatically.
-
-### Environment variables
-
-```bash
-export HTTPS_PROXY="http://proxy.corp.example:3128"
-export HTTP_PROXY="http://proxy.corp.example:3128"
-export NO_PROXY="localhost,127.0.0.1,.corp.example"
-
-cd rust
-./target/debug/claw prompt "hello via the corporate proxy"
-```
-
-### Programmatic `proxy_url` config option
-
-As an alternative to per-scheme environment variables, the `ProxyConfig` type exposes a `proxy_url` field that acts as a single catch-all proxy for both HTTP and HTTPS traffic. When `proxy_url` is set it takes precedence over the separate `http_proxy` and `https_proxy` fields.
-
-```rust
-use api::{build_http_client_with, ProxyConfig};
-
-// From a single unified URL (config file, CLI flag, etc.)
-let config = ProxyConfig::from_proxy_url("http://proxy.corp.example:3128");
-let client = build_http_client_with(&config).expect("proxy client");
-
-// Or set the field directly alongside NO_PROXY
-let config = ProxyConfig {
- proxy_url: Some("http://proxy.corp.example:3128".to_string()),
- no_proxy: Some("localhost,127.0.0.1".to_string()),
- ..ProxyConfig::default()
-};
-let client = build_http_client_with(&config).expect("proxy client");
-```
-
-### Notes
-
-- When both `HTTPS_PROXY` and `HTTP_PROXY` are set, the secure proxy applies to `https://` URLs and the plain proxy applies to `http://` URLs.
-- `proxy_url` is a unified alternative: when set, it applies to both `http://` and `https://` destinations, overriding the per-scheme fields.
-- `NO_PROXY` accepts a comma-separated list of host suffixes (for example `.corp.example`) and IP literals.
-- Empty values are treated as unset, so leaving `HTTPS_PROXY=""` in your shell will not enable a proxy.
-- If a proxy URL cannot be parsed, `claw` falls back to a direct (no-proxy) client so existing workflows keep working; double-check the URL if you expected the request to be tunnelled.

-## Common operational commands
-
-```bash
-cd rust
-./target/debug/claw status
-./target/debug/claw sandbox
-./target/debug/claw agents
-./target/debug/claw mcp
-./target/debug/claw skills
-./target/debug/claw system-prompt --cwd .. --date 2026-04-04
-```
-
-## Session management
-
-REPL turns are persisted under `.claw/sessions/` in the current workspace.
-
-```bash
-cd rust
-./target/debug/claw --resume latest
-./target/debug/claw --resume latest /status /diff
-```
-
-Useful interactive commands include `/help`, `/status`, `/cost`, `/config`, `/session`, `/model`, `/permissions`, and `/export`.
-
-## Config file resolution order
-
-Runtime config is loaded in this order, with later entries overriding earlier ones:
-
-1. `~/.claw.json`
-2. `~/.config/claw/settings.json`
-3. `/.claw.json`
-4. `/.claw/settings.json`
-5. `/.claw/settings.local.json`
-
-## Mock parity harness
-
-The workspace includes a deterministic Anthropic-compatible mock service and parity harness.
-
-```bash
-cd rust
-./scripts/run_mock_parity_harness.sh
-```
-
-Manual mock service startup:
-
-```bash
-cd rust
-cargo run -p mock-anthropic-service -- --bind 127.0.0.1:0
-```
-
-## Verification
-
-```bash
-cd rust
-cargo test --workspace
-```
-

- * Env-less Remote Control bridge core.
- *
- * "Env-less" = no Environments API layer. Distinct from "CCR v2" (the
- * /worker/* transport protocol) — the env-based path (replBridge.ts) can also
- * use CCR v2 transport via CLAUDE_CODE_USE_CCR_V2. This file is about removing
- * the poll/dispatch layer, not about which transport protocol is underneath.
- *
- * Unlike initBridgeCore (env-based, ~2400 lines), this connects directly
- * to the session-ingress layer without the Environments API work-dispatch
- * layer:
- *
- * 1. POST /v1/code/sessions (OAuth, no env_id) → session.id
- * 2. POST /v1/code/sessions/{id}/bridge (OAuth) → {worker_jwt, expires_in, api_base_url, worker_epoch}
- * Each /bridge call bumps epoch — it IS the register. No separate /worker/register.
- * 3. createV2ReplTransport(worker_jwt, worker_epoch) → SSE + CCRClient
- * 4. createTokenRefreshScheduler → proactive /bridge re-call (new JWT + new epoch)
- * 5. 401 on SSE → rebuild transport with fresh /bridge credentials (same seq-num)
- *
- * No register/poll/ack/stop/heartbeat/deregister environment lifecycle.
- * The Environments API historically existed because CCR's /worker/*
- * endpoints required a session_id+role=worker JWT that only the work-dispatch
- * layer could mint. Server PR #292605 (renamed in #293280) adds the /bridge endpoint as a direct
- * OAuth→worker_jwt exchange, making the env layer optional for REPL sessions.
- *
- * Gated by `tengu_bridge_repl_v2` GrowthBook flag in initReplBridge.ts.
- * REPL-only — daemon/print stay on env-based.
