Slice C of the #534 resplit: the eight fix commits you named, replayed onto current main (64e66369). No rename, no add_session rewrite, no workflow.md.

5a1d59e0 path containment · c0d7cb7f create/archive/link collisions · 1cf22b51 JSON read/write failures · cf8cb25c lifecycle hooks + config parsing · e1a17984 empty title/description rejection · a95e7483 archive index.lock retry · 9c88fec5 hook process-tree kill · c9489ce8 non-list children + advisory stat() guards

Conflict resolutions worth your eyes

Path containment (5a1d59e0) — 7 hunks. main had independently landed a weaker version of this check: resolve, then relative_to(repo_root). I took the fork side, which is a strict superset — it resolves both operands (so it still covers the symlink case main's version was written for), rejects the tasks directory itself as a target, and requires containment in tasks_dir rather than merely repo_root. Worth a close look since it's the one place I overrode existing main behaviour rather than adding to it.

regression.test.ts (three separate conflicts). Each incoming side dragged in the "shipped markdown carries no trailing whitespace" block from e77af366 — your "Also" bucket, not slice C, not on main. Took the HEAD side all three times, so that block stays out and lands with whatever slice you eventually want it in.

Dropped, not resolved: task artifacts carried along by the picks (08-08-*, 08-09-*, 08-19-*), and the workflow.md hunks from e1a17984.

One contradiction in the split, and how I handled it

task-children-normalization.integration.test.ts arrives with c9489ce8 — squarely slice C — but it drives task.py with TRELLIS_DEVELOPER: "tester". That env var is implemented by 0740d1d6, which you put in slice E, "only after C". So C's own test cannot pass on C as written.

Rather than pull E's feature forward, setupRepo now writes .trellis/.developer with name=tester — which get_developer() on current main already reads. The TRELLIS_DEVELOPER env in runTask is left untouched, so the test keeps passing unchanged once E lands. Happy to do it differently if you'd rather the test move to E.

Scope hygiene

Vendored .trellis/scripts and packaged templates/trellis/scripts verified byte-identical (diff -rq -x __pycache__). No .trellis/tasks/, no .trellis/workspace/sven/, no workflow.md, no marketplace gitlink, no -sd.N (stays 0.6.15).

Dogfood skill copies under .agents/, .claude/, .cursor/, .omp/, .opencode/, .pi/ are included so their docs match the new create-time validation — drop them if you'd rather refresh via trellis update.

Summary by CodeRabbit

  • New Features

    • Task creation now requires a non-empty description and supports --force for intentional overwrites.
    • Git operations automatically retry transient index-lock failures.
    • Added clearer diagnostics for invalid task data, configuration, JSON files, and lifecycle actions.
  • Bug Fixes

    • Improved task path safety, archive collision handling, parent-child linking, and malformed task recovery.
    • Prevented context validation failures when referenced files disappear.
    • Improved lifecycle hook timeout and cleanup behavior.
  • Documentation

    • Updated task creation examples and guidance to reflect required descriptions and validation rules.

Eight fix commits from the runtime-hardening audit, replayed onto current
main. No new commands: `rename`, the `add_session` rewrite and the
workflow.md changes are deliberately not here.

- path containment chokepoint in `resolve_task_dir`: candidate and tasks
  directory are both resolved before comparing, the tasks directory
  itself is rejected, and `find_task_by_name` refuses separators and
  ambiguous suffixes. Replaces a check that only required containment in
  the repo root.
- task create / archive / link collisions fail safely instead of
  silently overwriting or nesting
- JSON read and write failures are surfaced throughout the task runtime,
  with a strict/tolerant read split in `io.py`
- lifecycle hooks gain a timeout and full failure diagnostics; on
  timeout the whole hook process tree is killed, not just its leader
- config parsing consolidated with unified truthy semantics
- empty title or description is rejected at `task.py create` before any
  filesystem write
- archive auto-commit retries on a transient `index.lock`
- non-list `children` and the advisory `stat()` in validate are guarded

`task-children-normalization.integration.test.ts` sets `.trellis/.developer`
in its setup instead of relying on TRELLIS_DEVELOPER, which is part of the
worktree-identity change that is not in this PR.

📝 Walkthrough

Walkthrough

Task handling now validates descriptions, paths, metadata, archive destinations, hooks, configuration, and Git lock contention. Shared JSON and YAML helpers provide diagnostics. Regression tests cover failure and recovery paths. Task creation examples now include descriptions.

Changes

Task system hardening

Layer / File(s) Summary
Task lifecycle validation and mutation
.trellis/scripts/common/task_store.py, .trellis/scripts/common/task_utils.py, .trellis/scripts/common/task_context.py, .trellis/scripts/task.py
Task creation requires non-empty descriptions. Task paths, slugs, parents, archive destinations, child links, and metadata writes now receive validation and failure reporting.
Shared runtime reliability
.trellis/scripts/common/io.py, .trellis/scripts/common/config.py, .trellis/scripts/common/trellis_config.py, .trellis/scripts/common/git.py, .trellis/scripts/common/active_task.py, .trellis/scripts/common/safe_commit.py
JSON reads distinguish failure reasons. Writes use shared atomic I/O. YAML parsing reports unsupported constructs. Boolean configuration uses shared coercion. Git commands retry index-lock failures. Hooks enforce timeouts and capture diagnostics.
Regression coverage
packages/cli/test/regression.test.ts, packages/cli/test/scripts/*
Tests cover path containment, malformed task data, atomic mutations, hook behavior, configuration parsing, Git-lock retries, disappearing files, child-list normalization, and updated task creation arguments.
Documentation and templates
.agents/skills/..., .claude/skills/..., .cursor/skills/..., .omp/skills/..., .opencode/skills/..., .pi/skills/..., .trellis/spec/..., packages/cli/src/templates/...
Task creation examples now pass --description, and guidance describes non-empty title and description validation.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to f091d

The PR hardens task creation and hook execution, but the current head can still leave a timed-out hook process unreaped and retains documentation, consent-gating, and markdown-lint follow-ups. It is mergeable with explicit owner awareness, with bounded runtime cleanup and maintenance risks remaining.

Pull request overview

This PR hardens the Trellis Python task-script runtime (both the vendored .trellis/scripts copy and the shipped CLI templates), focusing on safer path handling, more diagnosable JSON/config failures, and more reliable lifecycle hooks—plus updated integration tests and documentation to match the new runtime behavior.

Changes:

  • Makes task.py create require a non-empty --description and updates tests/docs/prompts accordingly.
  • Introduces stricter task-dir containment + safer task linking/archiving behavior (collision handling, children normalization, write-failure handling).
  • Consolidates and strengthens runtime robustness: checked JSON reads with actionable diagnostics, YAML parsing centralized + warning on unsupported constructs, hook execution bounded by timeout with best-effort process-tree kill and captured output.

This skill creates task directories immediately, but it does not require explicit task-creation consent. The new --description arguments make the commands satisfy the hardened CLI and therefore make the filesystem writes executable. Add the same task-creation consent gate used by the other brainstorm skill copies before creating the parent or child task.

Also applies to: 457-458

In @.omp/skills/trellis-brainstorm/SKILL.md at line 70, Update the brainstorm
skill’s task-creation workflow around the TASK_DIR command to require explicit
task-creation consent before invoking task.py create, including both parent and
child task creation paths; reuse the consent gate established in the other
brainstorm skill copies and ensure no task directories are created before
consent is granted.

Comment thread packages/cli/src/templates/trellis/scripts/common/task_utils.py Outdated
- run_task_hooks relied on Popen's context manager, whose exit calls wait()
  with no timeout. If _kill_hook_tree failed outright the lifecycle command
  would block there forever -- the exact hang the timeout exists to prevent.
  Cleanup is now explicit and bounded by HOOK_KILL_GRACE_SECONDS.

- read_json_checked caught FileNotFoundError and OSError. UnicodeDecodeError
  is neither, so a task.json that is not UTF-8 escaped both handlers and
  surfaced as a traceback. It now reports JSON_READ_UNDECODABLE, named as an
  encoding problem rather than a parse error.

- cmd_start printed a generic 'Task not found' on stdout after
  resolve_task_dir had already named the exact reason on stderr, splitting one
  diagnosis across two streams and burying the specific message.

Two regression tests added; both fail without their fix. Also rewords a test
fixture comment that asserted TRELLIS_DEVELOPER is unimplemented -- true on
this branch, misleading once the lifecycle PR stacks on it.

413-476: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Add bounded process cleanup in both run_task_hooks copies. If the follow-up communicate() call times out, the timeout branch continues without closing the pipes or reaping the hook. Add a finally block that calls _release_hook_process(proc) when proc is not None.
