PR & Logbook Composer

The skill that turns a finished change into a PR a reviewer can read in under five minutes, and a logbook entry the next agent can pick up cold.

When to activate

• Opening a new PR.
• Updating the body of an existing PR after review feedback.
• Appending a logbook entry to the PR's linked issue.
• Drafting the squash-merge commit message.

Operating mode

1. Read the project's PR contract

Before composing, read the project's AGENTS.md (or equivalent) for:

• The required PR sections.
• The commit-message convention (Gitmoji, Conventional Commits, etc.).
• The logbook label and where logbook issues live.
• Any branch-naming or merge-method rules.

Do not assume a convention. The same crew of agents serves repos with different rules.

2. PR title

• Under 70 characters. Imperative mood. No trailing period.
• For Gitmoji projects, lead with the appropriate emoji.
• The title states what changed, not why. The body explains why.

3. PR body — read this first / how to test / detailed

Default crewrig template — adapt to the project's AGENTS.md if it specifies otherwise:

<Two sentences max — purpose, for a human reader.>

## How to read this PR?

<Reading order. Highlight the load-bearing files. Call out
non-obvious design decisions and why they were made.>

## How to test this PR?

<Step-by-step. Prerequisites, commands, expected outcomes. Cover the
golden path and at least one failure mode.>

## Detailed description (for agents)

<Structured walkthrough of every change, intended for the next agent
that touches this code. Be explicit about additions, modifications,
deletions, and the rationale for each.>

4. Logbook entries

Before creating a new logbook issue, check whether the PR already closes an existing feature issue (scan the PR body for Closes #N, Fixes #N, Resolves #N patterns). If a feature issue exists:

1. Append the logbook entry to that issue as a comment via the GitHub MCP add_issue_comment tool (or gh issue comment <N> --body "...").
2. Ensure the issue carries the logbook label — add it with gh issue edit <N> --add-label logbook if absent.
3. Do not create a new logbook issue. The feature ticket is the logbook.

A standalone logbook issue is only warranted when the PR has no upstream feature ticket (hotfix, dependency bump, automation run with no prior ticket).

A logbook is not a status update. It is the record the next agent will read to avoid your mistakes. Optimise for that reader.

### YYYY-MM-DD — <one-line topic>

**Context**: <what task / PR this entry attaches to>

**What was tried**: <decision or experiment>

**Outcome**: <green / red / partial — with link to evidence>

**Lesson**: <the durable insight, in one sentence>

Append, never rewrite. Even a wrong-turn that was reverted belongs in the log — the next agent needs to know it was tried.

5. Squash-merge commit message

When the project squash-merges, the commit message is what survives in git log forever. Compose it deliberately:

<gitmoji or convention> <imperative-title> (#<pr-number>)

<one paragraph: what the PR delivered, in past tense>

<one paragraph: why — the constraint or motivation that drove it>

<bullet list of significant follow-ups, if any>

Co-authored-by lines, if any.

Do not paste the entire PR description. The commit message is denser.

6. Pre-push sanity checks

Text-only tooling silently drops file metadata. Verify before pushing:

• If the diff touches shell scripts, confirm executable bits survived the round-trip: git ls-files --stage -- '*.sh' must show 100755, not 100644. The MCP push_files tool strips the exec bit. Restore with git update-index --chmod=+x <file> and amend before pushing.

7. Post-merge cleanup

After the squash-merge commit lands on the target branch:

1. Close the logbook issue: gh issue close <logbook-issue-number> --reason completed or via the GitHub MCP issue_write tool with state: "closed" and state_reason: "completed".
2. If the PR also closes a feature issue (detected via Closes #N / Fixes #N / Resolves #N in §4), confirm that issue is closed too — GitHub auto-closes on merge when the keyword is in the PR body, but verify rather than assume.

Skip step 1 if the logbook entry was appended to an existing feature issue (the §4 upstream-check path) — closing the feature issue is sufficient.

Cross-cutting: skill / agent source version bumps

This is not a step in the composition lifecycle — it is a rule that applies to any PR you compose whose diff touches a community-config/skills/*/SKILL.md or community-config/agents/*/AGENT.md source. The PR MUST bump provenance.version in the same diff. The rule is enforced by scripts/check-skill-versions.sh in CI (and locally via task check-skill-versions).

SemVer applies:

• PATCH for friction-driven fixes and wording changes (the common case — most curator-driven fixes are PATCH).
• MINOR for additive changes (new section, new recognition signal, new optional payload field).
• MAJOR for breaking contract changes (removed payload fields, renamed required fields, semantics flip).

A "version-only bump" PR is not a thing — the version bump always accompanies the content edit. See community-config/FORMAT.md → Version semantics for the contract.

Grounding discipline

PR bodies, logbook entries, and squash commit messages compose under narrative pressure — the temptation is to produce a fluent paragraph that sounds like a faithful summary. Plausible-sounding detail is the failure mode, not vague writing.

Hard rule. Every technical claim MUST cite a verifiable source — a file path with line range, a command output excerpt, or a sentence from the input brief. This applies to file counts, line counts, assertion lists, pass-count deltas, exit codes, CI step names, and build-system invariants (e.g. "content-addressed", "drift-free", "idempotent"). If you cannot cite, write "see diff" or omit the claim. Do not estimate, round, or generalise.

Self-check before returning. Re-read the draft once. Mark every number, list-count, named invariant, and concrete technical assertion. For each mark, ask: does this trace to a file path, a command output, or a sentence in my brief? If no, delete it or replace it with "see diff". The self-check is cheap; a fabricated claim that reaches a reviewer or CI is not.

Output expectations

• All output in the project's primary language (English by default per crewrig convention; check the project's AGENTS.md for overrides).
• Markdown that renders cleanly on the project's PR platform.
• No emoji in the body unless the project's convention uses them.

Friction reporting

When a recognition signal fires (see config/TOOLS.md → Friction Reporting → Recognition signals), invoke the harness-report skill rather than reimplementing the protocol inline. The reporter walks you through identifying the offender, picking the room, and filling the payload.

Idle behavior

When re-activated after going idle with no new assignment, confirm availability in one sentence. Do not re-summarise a completed task.

Example: "Task #2 (logbook + PR for #N) is already completed — available for new work."

Shutdown protocol

When the team lead sends a shutdown_request message, respond immediately with shutdown_response (approve: true) and stop:

{"type": "shutdown_response", "request_id": "<id from request>", "approve": true}

Do not defer, summarise completed tasks, or wait for an ongoing operation. The shutdown_request is a hard stop signal — the team lead has confirmed all work is done.

After completing a task and reporting to the team lead, do not start any further processing or re-enter a wait loop. Mark the task as completed via TaskUpdate, send the completion message, and then stop. The team lead will send the next assignment or the shutdown signal.
