Returns structured `{title, body}` for the caller to apply — this skill never invokes `gh pr edit` or `gh pr create`, and never prompts for interactive confirmation. + +Why a separate skill: several callers need the same writing logic without the single-PR interactive scaffolding that lives in `git-commit-push-pr`. `ce-pr-stack`'s splitting workflow runs this once per layer as a batch; `git-commit-push-pr` runs it inside its full-flow and refresh-mode paths. Extracting keeps one source of truth for the writing principles. + +**Naming rationale:** `ce-pr-description`, not `git-pr-description`. Stacking and PR creation are GitHub features; the "PR" in the name refers to the GitHub artifact. Using the `ce-` prefix matches the future convention for plugin skills; sibling `git-*` skills will rename to `ce-*` later, and this skill starts there directly. + +--- + +## Inputs + +Callers pass one of the two input forms below, plus an optional focus hint. If invoked directly by the user with no explicit form, infer from context (an existing open PR on the current branch -> `pr:`; a branch with no PR yet -> `range:..HEAD`). + +- **`pr: `** -- generate description for an existing PR. The skill reads title, body, and commit list via `gh pr view`, and derives the diff from the PR's commit range. +- **`range: ..`** -- generate description for an arbitrary range without requiring an existing PR. Useful before a PR is created, or as a dry-run for a branch being prepared for stack submission. +- **`focus: `** (optional) -- a user-provided steering note such as "include the benchmarking results" or "emphasize the migration safety story". Incorporate alongside the diff-derived narrative; do not let focus override the value-first principles. + +## Output + +Return a structured result with two fields: + +- **`title`** -- conventional-commit format: `type: description` or `type(scope): description`. Under 72 characters. Choose `type` based on intent (feat/fix/refactor/docs/chore/perf/test), not file type. Pick the narrowest useful `scope` (skill or agent name, CLI area, or shared label); omit when no single label adds clarity. +- **`body`** -- markdown following the writing principles below. + +The caller decides whether to apply via `gh pr edit`, `gh pr create`, or discard. This skill does NOT call those commands itself. + +--- + +## What this skill does not do + +- No interactive confirmation prompts. If the diff is ambiguous about something important (e.g., the focus hint conflicts with the actual changes), surface the ambiguity in the returned output or raise it to the caller — do not prompt the user directly. +- No branch checkout or assumption that HEAD is the target branch. Work from the input (`pr:` or `range:`) only. +- No compare-and-confirm narrative ("here's what changed since the last version"). The description describes the end state; the caller owns any compare-and-confirm framing. +- No auto-apply via `gh pr edit` or `gh pr create`. Return the output and stop. + +Interactive scaffolding (confirmation prompts, compare-and-confirm, apply step) is the caller's responsibility. + +--- + +## Step 1: Resolve the diff and commit list + +### If input is `pr: ` + +Fetch PR metadata and commit list: + +```bash +gh pr view --json number,state,title,body,baseRefName,headRefName,headRepositoryOwner,headRepository,commits,url +``` + +If the returned `state` is not `OPEN`, report "PR is (not open); cannot regenerate description" and exit gracefully without output. Callers expecting `{title, body}` must handle this empty case. + +Resolve the base remote and base branch from the PR metadata. Fall back to `origin` as the remote when match detection is ambiguous. Derive the diff range as `/...`. + +Verify the base remote-tracking ref exists; fetch if needed: + +```bash +git rev-parse --verify / 2>/dev/null || git fetch --no-tags +``` + +Gather merge base, commit list, and full diff: + +```bash +MERGE_BASE=$(git merge-base / ) && echo "MERGE_BASE=$MERGE_BASE" && echo '=== COMMITS ===' && git log --oneline $MERGE_BASE.. && echo '=== DIFF ===' && git diff $MERGE_BASE... +``` + +Also capture the existing PR body for evidence preservation in Step 3. + +### If input is `range: ..` + +Validate both endpoints resolve: + +```bash +git rev-parse --verify 2>/dev/null && git rev-parse --verify 2>/dev/null +``` + +If either fails, report "Invalid range: .. -- does not resolve" and exit gracefully without output. + +Gather merge base, commit list, and full diff: + +```bash +MERGE_BASE=$(git merge-base ) && echo "MERGE_BASE=$MERGE_BASE" && echo '=== COMMITS ===' && git log --oneline $MERGE_BASE.. && echo '=== DIFF ===' && git diff $MERGE_BASE... +``` + +If the commit list is empty, report "No commits between and " and exit gracefully. + +--- + +## Step 2: Classify commits before writing + +Scan the commit list and classify each commit: + +- **Feature commits** -- implement the PR's purpose (new functionality, intentional refactors, design changes). These drive the description. +- **Fix-up commits** -- iteration work (code review fixes, lint fixes, test fixes, rebase resolutions, style cleanups). Invisible to the reader. + +When sizing the description, mentally subtract fix-up commits: a branch with 12 commits but 9 fix-ups is a 3-commit PR. + +--- + +## Step 3: Decide on evidence + +Decide whether evidence capture is possible from the full branch diff. + +**Evidence is possible** when the diff changes observable behavior demonstrable from the workspace: UI, CLI output, API behavior with runnable code, generated artifacts, or workflow output. + +**Evidence is not possible** for: +- Docs-only, markdown-only, changelog-only, release metadata, CI/config-only, test-only, or pure internal refactors +- Behavior requiring unavailable credentials, paid/cloud services, bot tokens, deploy-only infrastructure, or hardware not provided + +**This skill does NOT prompt the user** to capture evidence. The decision logic is: + +1. **Input was `pr:` and the existing body contains a `## Demo` or `## Screenshots` section with image embeds:** preserve it verbatim unless the `focus:` hint asks to refresh or remove it. Include the preserved block in the returned body. +2. **Otherwise:** omit the evidence section entirely. If the caller wants to capture evidence, the caller is responsible for invoking `ce-demo-reel` separately and splicing the result in, or for asking this skill to regenerate with an updated focus hint after capture. + +Do not label test output as "Demo" or "Screenshots". Place any preserved evidence block before the Compound Engineering badge. + +--- + +## Step 4: Frame the narrative before sizing + +Articulate the PR's narrative frame: + +1. **Before**: What was broken, limited, or impossible? (One sentence.) +2. **After**: What's now possible or improved? (One sentence.) +3. **Scope rationale** (only if 2+ separable-looking concerns): Why do these ship together? (One sentence.) + +This frame becomes the opening. For small+simple PRs, the "after" sentence alone may be the entire description. + +--- + +## Step 5: Size the change + +Assess size (files, diff volume) and complexity (design decisions, trade-offs, cross-cutting concerns) to select description depth: + +| Change profile | Description approach | +|---|---| +| Small + simple (typo, config, dep bump) | 1-2 sentences, no headers. Under ~300 characters. | +| Small + non-trivial (bugfix, behavioral change) | Short narrative, ~3-5 sentences. No headers unless two distinct concerns. | +| Medium feature or refactor | Narrative frame (before/after/scope), then what changed and why. Call out design decisions. | +| Large or architecturally significant | Full narrative: problem context, approach (and why), key decisions, migration/rollback if relevant. | +| Performance improvement | Include before/after measurements if available. Markdown table works well. | + +When in doubt, shorter is better. Match description weight to change weight. + +--- + +## Step 6: Apply writing principles + +### Writing voice + +If the repo has documented style preferences in context, follow those. Otherwise: + +- Active voice. No em dashes or `--` substitutes; use periods, commas, colons, or parentheses. +- Vary sentence length. Never three similar-length sentences in a row. +- Do not make a claim and immediately explain it. Trust the reader. +- Plain English. Technical jargon fine; business jargon never. +- No filler: "it's worth noting", "importantly", "essentially", "in order to", "leverage", "utilize." +- Digits for numbers ("3 files"), not words ("three files"). + +### Writing principles + +- **Lead with value**: Open with what's now possible or fixed, not what was moved around. The subtler failure is leading with the mechanism ("Replace the hardcoded capture block with a tiered skill") instead of the outcome ("Evidence capture now works for CLI tools and libraries, not just web apps"). +- **No orphaned opening paragraphs**: If the description uses `##` headings anywhere, the opening must also be under a heading (e.g., `## Summary`). For short descriptions with no sections, a bare paragraph is fine. +- **Describe the net result, not the journey**: The description covers the end state, not how you got there. No iteration history, debugging steps, intermediate failures, or bugs found and fixed during development. This applies equally when regenerating for an existing PR: rewrite from the current state, not as a log of what changed since the last version. Exception: process details critical to understand a design choice. +- **When commits conflict, trust the final diff**: The commit list is supporting context, not the source of truth. If commits describe intermediate steps later revised or reverted, describe the end state from the full branch diff. +- **Explain the non-obvious**: If the diff is self-explanatory, don't narrate it. Spend space on things the diff doesn't show: why this approach, what was rejected, what the reviewer should watch. +- **Use structure when it earns its keep**: Headers, bullets, and tables aid comprehension, not mandatory template sections. +- **Markdown tables for data**: Before/after comparisons, performance numbers, or option trade-offs communicate well as tables. +- **No empty sections**: If a section doesn't apply, omit it. No "N/A" or "None." +- **Test plan — only when non-obvious**: Include when testing requires edge cases the reviewer wouldn't think of, hard-to-verify behavior, or specific setup. Omit when "run the tests" is the only useful guidance. When the branch adds test files, name them with what they cover. + +### Visual communication + +Include a visual aid only when the change is structurally complex enough that a reviewer would struggle to reconstruct the mental model from prose alone. + +**When to include:** + +| PR changes... | Visual aid | +|---|---| +| Architecture touching 3+ interacting components | Mermaid component or interaction diagram | +| Multi-step workflow or data flow with non-obvious sequencing | Mermaid flow diagram | +| 3+ behavioral modes, states, or variants | Markdown comparison table | +| Before/after performance or behavioral data | Markdown table | +| Data model changes with 3+ related entities | Mermaid ERD | + +**When to skip:** +- Sizing routes to "1-2 sentences" +- Prose already communicates clearly +- The diagram would just restate the diff visually +- Mechanical changes (renames, dep bumps, config, formatting) + +**Format:** +- **Mermaid** (default) for flows, interactions, dependencies. 5-10 nodes typical, up to 15 for genuinely complex changes. Use `TB` direction. Source should be readable as fallback. +- **ASCII diagrams** for annotated flows needing rich in-box content. 80-column max. +- **Markdown tables** for comparisons and decision matrices. +- Place inline at point of relevance, not in a separate section. +- Prose is authoritative when it conflicts with a visual. + +Verify generated diagrams against the change before including. + +### Numbering and references + +Never prefix list items with `#` in PR descriptions — GitHub interprets `#1`, `#2` as issue references and auto-links them. + +When referencing actual GitHub issues or PRs, use `org/repo#123` or the full URL. Never use bare `#123` unless verified. + +### Applying the focus hint + +If a `focus:` hint was provided, incorporate it alongside the diff-derived narrative. Treat focus as steering, not override: do not invent content the diff does not support, and do not suppress important content the diff demands simply because focus did not mention it. When focus and diff materially disagree (e.g., focus says "include benchmarking" but the diff has no benchmarks), note the conflict in a way the caller can see (leave a brief inline note or raise to the caller) rather than fabricating content. + +--- + +## Step 7: Compose the title + +Title format: `type: description` or `type(scope): description`. + +- **Type** is chosen by intent, not file extension. `feat` for new functionality, `fix` for a bug fix, `refactor` for a behavior-preserving change, `docs` for doc-only, `chore` for tooling/maintenance, `perf` for performance, `test` for test-only. +- **Scope** (optional) is the narrowest useful label: a skill/agent name, CLI area, or shared area. Omit when no single label adds clarity. +- **Description** is imperative, lowercase, under 72 characters total. No trailing period. +- If the repo has commit-title conventions visible in recent commits, match them. + +Breaking changes use `!` (e.g., `feat!: ...`) or document in the body with a `BREAKING CHANGE:` footer. + +--- + +## Step 8: Compose the body + +Assemble the body in this order: + +1. **Opening** -- the narrative frame from Step 4, at the depth chosen in Step 5. Under a heading (e.g., `## Summary`) if the description uses any `##` headings elsewhere; a bare paragraph otherwise. +2. **Body sections** -- only the sections that earn their keep for this change: what changed and why, design decisions, tables for data, visual aids when complexity warrants. Skip empty sections entirely. +3. **Test plan** -- only when non-obvious per the writing principles. Omit otherwise. +4. **Evidence block** -- only the preserved block from Step 3, if one exists. Do not fabricate or placeholder. +5. **Compound Engineering badge** -- append a badge footer separated by a `---` rule. Skip if the existing body (for `pr:` input) already contains the badge. + +**Badge:** + +```markdown +--- + +[![Compound Engineering](https://img.shields.io/badge/Built_with-Compound_Engineering-6366f1)](https://github.com/EveryInc/compound-engineering-plugin) +![HARNESS](https://img.shields.io/badge/MODEL_SLUG-COLOR?logo=LOGO&logoColor=white) +``` + +**Harness lookup:** + +| Harness | `LOGO` | `COLOR` | +|---------|--------|---------| +| Claude Code | `claude` | `D97757` | +| Codex | (omit logo param) | `000000` | +| Gemini CLI | `googlegemini` | `4285F4` | + +**Model slug:** Replace spaces with underscores.

This applies equally to description updates: rewrite from the current state, not as a log of what changed since the last version.

Spend space on things the diff doesn't show: why this approach, what was rejected, what the reviewer should watch. -- **Use structure when it earns its keep**: Headers, bullets, and tables aid comprehension, not mandatory template sections. -- **Markdown tables for data**: Before/after comparisons, performance numbers, or option trade-offs communicate well as tables. -- **No empty sections**: If a section doesn't apply, omit it. No "N/A" or "None." -- **Test plan -- only when non-obvious**: Include when testing requires edge cases the reviewer wouldn't think of, hard-to-verify behavior, or specific setup.

Parse feedback targets + +For each comment being addressed, extract the file path and line range under discussion. This already happens in the parent skill's fetch/triage phases -- reuse the `path`, `line`, and thread/comment body it produced. Do not re-fetch. + +If a comment has no file/line context (e.g., a top-level `pr_comment` or `review_body` without a thread anchor), it cannot be attributed to a specific layer by blame. Fall back to the non-stack flow for that comment: apply the fix on the current (commented) branch and reply there. + +### 2. Identify the owning layer + +This is the one nontrivial step. For each comment that has file/line context: + +1. Run `git blame` scoped to the lines under discussion: + + ```bash + git blame -L <start>,<end> -- <file> + ``` + +2. Capture the commit SHAs that introduced those lines. + +3. Map each SHA to a stack layer by cross-referencing the stack's commits. Use `gh stack view --json` to get machine-readable layer information: + + ```bash + gh stack view --json + ``` + + Walk each layer's commits and match against the SHAs from blame. (If `--json` is unavailable in the current gh-stack version, parse the human output from `gh stack view` -- the `--help`-first pattern covers this.) + +4. Classify the result: + + - **Single owning layer** -- all blamed SHAs map to one layer. That layer is the fix target. + - **Multiple layers** -- blamed SHAs span two or more layers in the stack. Ask the user which layer to fix in, defaulting to the earliest (most upstream) layer. If the user declines the default and picks "apply in multiple layers", this is the V1-deferred multi-layer case -- stop the automated workflow, explain the limitation, and hand off for manual resolution. + - **Outside the stack** -- blamed SHAs map to a commit that is not in any stack layer (typically the base branch). Fall back to the non-stack flow: treat this as normal feedback on the current (commented) branch. Note the fall-back in the reply so the reader understands why the fix landed there. + - **Owning layer already merged and removed from the stack** -- the blamed commit belongs to a layer that has since been merged (its branch is gone from `gh stack view`). Fall back to applying the fix on the current (commented) layer, and include a short note in the reply: "Fixed on the current layer; the originally-owning layer has already merged." + +### 3. Navigate to the owning layer + +If the owning layer is a layer in the current stack (the common happy path), switch to it: + +```bash +gh stack checkout <owning-layer-branch> +``` + +If the fix target is the current branch already (owning layer is the commented PR's layer), skip this step. + +### 4. Apply the fix + +Apply the fix using the parent skill's fix-application logic. The content of the fix is not stack-specific -- read the code, decide the right change, edit the files. The difference is only which branch the edits happen on. + +### 5. Commit + +Stage and commit with a conventional message referencing the review: + +```bash +git add <files-changed> +git commit -m "fix: address review feedback on <aspect>" +``` + +Do NOT invoke `git-commit-push-pr` or any other shipping skill -- the parent skill and this reference handle the stack-specific push via `gh stack push` in step 7 below. + +### 6. Cascade via `gh stack rebase` + +Run a cascading rebase so each layer on top of the owning layer re-applies on the new commit: + +```bash +gh stack rebase +``` + +Documented behavior: "Pull from remote and do a cascading rebase across the stack. Ensures that each branch in the stack has the tip of the previous layer in its commit history." This also pulls from the remote as part of the rebase, so upstream changes to other layers made while the user was working on feedback are incorporated. + +Classify the result: + +- **Clean success** -- no conflicts, no unexpected remote content. Continue to step 7. +- **Rebase conflicts** -- halt. Report which layer conflicted. Do not push. Provide manual resolution guidance: + + > Rebase conflicted on `<layer-name>`. Resolve the conflict manually, then run one of: + > - `gh stack rebase --continue` to resume the cascade after resolving, or + > - `gh stack rebase --abort` to restore all branches to their pre-rebase state. + > + > Once the rebase completes, re-run this skill (or push manually with `gh stack push`) and I'll pick up from the reply step. + + Exit the workflow. Do not attempt to push a partially-rebased stack. + +- **Unexpected remote content pulled in** -- the remote had changes on sibling layers that the user had not seen locally, and the rebase incorporated them. Before pushing, summarize what changed (which layers gained commits, what those commits are about if visible from `gh stack view`) and ask the user whether to proceed. Do NOT silently push surprise content. + +- **Top-of-stack with no layers above** -- rebase is effectively a no-op for cascading (there is nothing to cascade into). Proceed to push normally. + +### 7. Push + +Push all layers: + +```bash +gh stack push +``` + +`gh stack push` uses `--force-with-lease` to safely update rebased branches without clobbering concurrent remote changes. + +If the push fails with a force-with-lease rejection (remote has commits the local stack does not), advise the user: + +> Push was rejected because the remote stack has changes your local stack does not. Run `gh stack sync` to pull remote changes, then re-run this skill to apply and re-push. + +Exit. Do not retry blindly; `gh stack sync` is the recovery path. + +### 8. Reply on the correct PR + +Post the reply to the **original commented PR** -- not the owning layer's PR if they differ. This keeps the conversation on the thread the reviewer started. + +Use the parent skill's reply mechanism (`scripts/reply-to-pr-thread` for review threads, `gh pr comment` for top-level comments and review bodies). + +When the fix landed on a different layer than the commented PR, prefix the reply's resolution text with a short owning-layer note. Example: + +```markdown +> [quoted relevant part of original feedback] + +Fixed in the `<layer-branch-name>` layer (PR #NNNN), which owns this code in the stack. + +Addressed: [brief description of the fix] +``` + +When the fix landed on the commented PR's own layer (the common case), the reply is unchanged from the non-stack flow. + +When the fall-back branches fired (blame outside the stack, or owning layer already merged), include the corresponding note from step 2 so the reader understands why the fix landed where it did. + +After replying, resolve the thread as in the non-stack flow (except for `needs-human` verdicts, which remain open). + +--- + +## After the workflow + +Return control to the parent skill for the verification step (re-fetch threads) and summary. The only stack-specific addition to the summary is a brief line per fix noting the owning layer when it differs from the commented PR -- the parent skill's summary format accommodates this as extra context in the per-item description.
