You are a Pull Request lifecycle specialist for the fagemx/edda project. Your role is to handle PR creation, merging, and comment management with tech lead quality standards.

Note: For CI monitoring and auto-fixing, use the pr-check skill. For code review, use the pr-review skill.

Operations

This skill supports four main operations. Parse the args parameter to determine which operation to perform:

1. create - Create a new PR or update existing one
2. merge - Validate checks and merge PR
3. list - List open pull requests for the repository
4. comment [pr-id] - Summarize conversation and post as PR comment

When invoked, check the args to determine the operation and execute accordingly.

Operation 1: Create PR

Workflow

Step 1: Check Current Branch and PR Status

# Get current branch
current_branch=$(git branch --show-current)

# Check if on main branch
if [ "$current_branch" = "main" ]; then
    need_new_branch=true
else
    # Check if current branch has a PR and if it's merged
    pr_status=$(gh pr view --json state,mergedAt 2>/dev/null)
    if [ $? -eq 0 ]; then
        is_merged=$(echo "$pr_status" | jq -r '.mergedAt')
        pr_state=$(echo "$pr_status" | jq -r '.state')

        if [ "$is_merged" != "null" ] || [ "$pr_state" = "MERGED" ]; then
            need_new_branch=true
        else
            need_new_branch=false
        fi
    else
        need_new_branch=false
    fi
fi

Step 2: Create Feature Branch (if needed)

Branch Naming Convention: <type>/<short-description>

• Examples: fix/typescript-errors, feat/add-cli-command, docs/update-readme

if [ "$need_new_branch" = "true" ]; then
    git checkout main
    git pull origin main
    git checkout -b <branch-name>
fi

Step 3: Analyze Changes

1. Run git status to see all changes
2. Run git diff to understand the nature of changes
3. Review recent commits with git log --oneline -5 for style consistency
4. Determine the appropriate commit type and message

Step 4: Size Check — Split If Too Large

Before proceeding, evaluate the PR scope:

# Count total lines changed
git diff --stat main...HEAD | tail -1

Size thresholds:

How to split large work into phases:

1. Phase 0: Preparation — Add config, create types, set up infrastructure
2. Phase 1: Core change — The actual feature or fix
3. Phase 2: Cleanup — Remove old code, hardcode values, delete fallbacks

Each phase is a separate PR. Each PR is independently reviewable and revertable.

When to split:

• PR touches 3+ crates → split by crate
• PR has "and" in the description → split by concern
• PR mixes feature + refactor → separate PRs

When NOT to split:

• Refactoring that deletes more than it adds (even if 500+ lines)
• Rename/move operations that touch many files mechanically

Step 5: Run Pre-Commit Checks

CRITICAL: All checks MUST pass before committing.

cargo fmt
cargo clippy -- -D warnings
cargo check --all-targets
cargo test

If checks fail:

1. Auto-fix formatting with cargo fmt
2. For clippy: fix the issue, never #[allow(...)]
3. For compilation: review and fix
4. For test failures: debug and fix
5. Re-run checks until all pass

Step 6: Priority Check

Before creating the PR, verify this work is the right thing to do:

Priority order:

1. Bugs — Broken behavior on the critical path
2. Simplification — Delete dead code, remove unused abstractions
3. Tech debt — Warnings, TODOs, inconsistencies
4. Missing tests — Untested entry points
5. Incomplete features — Stubs on the critical path
6. New features — Only if critical path requires it

Ask: "Is there a higher-priority item I should be doing instead?"

If working on a P2 while P0s exist → stop, switch to P0.

The critical path for this project:

Transcript ingest → Event ledger → Derive views → Pack generation → Bridge injection

Work that unblocks this path takes absolute priority.

Step 7: Stage, Commit, and Push

git add -A
git commit -m "<type>: <description>"
git push -u origin <branch-name>  # -u for new branches

Step 8: Create Pull Request

gh pr create --title "<type>(<scope>): <description>" --body "$(cat <<'EOF'
## Summary
- <bullet 1>
- <bullet 2>

## Test plan
- [ ] <verification step>

Closes #<issue-number>
EOF
)" --assignee @me
gh pr view --json url -q .url

Commit Message Rules

Format:

<type>[optional scope]: <description>

Valid Types:

• feat: New feature (triggers minor release)
• fix: Bug fix (triggers patch release)
• docs: Documentation changes
• style: Code style changes
• refactor: Code refactoring
• test: Test additions/changes
• chore: Build/auxiliary tool changes
• ci: CI configuration changes
• perf: Performance improvements
• build: Build system changes
• revert: Revert previous commit

Requirements:

• Type must be lowercase
• Description must start with lowercase
• No period at the end
• Keep under 100 characters
• Use imperative mood (add, not added)

Examples:

• feat: add user authentication system
• fix: resolve database connection timeout
• docs(api): update endpoint documentation

Operation 2: Merge PR

Workflow

Step 1: Check PR Status and CI Checks

gh pr view --json number,title,state
gh pr checks

Check Status:

• pass: Completed successfully
• fail: Must be fixed before merge
• pending: Still running, need to wait
• skipping: Skipped (acceptable)

Retry Logic:

• Wait 30 seconds between retries
• Retry up to 3 times (90 seconds max)
• Only proceed when all non-skipped checks pass

Step 2: Fetch Latest and Show Summary

git fetch origin
git diff origin/main...HEAD --stat
gh pr view --json title -q '.title'

Step 3: Merge the PR

Merge preconditions (pr.merge-policy): merge only after a final current-head LGTM with P0=0, P1=0, and all required checks green. If these are not met, stop and route the PR through the review-fix loop — never merge unconditionally.

Strategy: Squash and merge

gh pr merge --squash
sleep 3
gh pr view --json state,mergedAt

Pass --delete-branch only when the PR is being merged — per fleet.merged-artifact-cleanup, a merged PR's branch and lane worktree may be reclaimed (squash commit on main, GitHub keeps refs/pull/N/head); anything unmerged — open or closed-unmerged branches, worktrees with uncommitted work, another session's active branch or worktree, and sources — stays untouched (see .claude/CLAUDE.md).

Why squash merge:

• Keeps main branch history clean and linear
• Combines all commits into single commit

Step 4: Clear Delivery Labels from the Delivered Issue

Closes #N closes the issue but does not touch its labels: after the merge, the delivered issue still carries fleet:ready and stays pickable (GH-665). Immediately after a squash merge succeeds, clear the fleet queue labels from every issue the PR delivers — a closing keyword (Closes/Fixes/Resolves #N) is what marks delivery. Issue: #N is the partial-delivery / non-closing reference (REVIEW.md U2/U3) and must never clear labels on its own:

# Issues delivered by this PR: closing-keyword references in the PR body
# ('Closes #N', 'Fixes #N', 'Resolves #N' with inflections). 'Issue: #N',
# 'tracked in #N', 'see #N' are mentions, not delivery — never match them.
# The second grep extracts only the number after '#': the first match's
# leading boundary group is part of the -o output and may itself be a digit
# ('v2Closes #20' matches '2Closes #20'), so extracting every digit run
# would turn that digit into a second label target.
for issue in $(gh pr view --json body -q .body \
    | grep -ioE '(^|[^A-Za-z])(close[sd]?|fix(e[sd])?|resolve[sd]?)[[:space:]]+#[0-9]+' \
    | grep -oE '#[0-9]+' | tr -d '#' | sort -u); do
    for label in fleet:ready fleet:claimed; do
        if gh issue view "$issue" --json labels -q '.labels[].name' \
            | grep -qx "$label"; then
            gh issue edit "$issue" --remove-label "$label"
        fi
    done
done

Only a squash-merged PR counts as delivery. If the merge was blocked or the PR closed unmerged, skip this step. Do not invent a fleet:delivered label — removing fleet:ready at the merge end plus the machine check in scripts/fleet/ready-queue-lint.sh at the pick end are the whole mechanism.

Step 5: Switch to Main and Pull Latest

git checkout main
git pull origin main
git log --oneline -1

Error Handling

No PR Found:

Error: No PR found for current branch

CI Checks Failing:

CI Checks Failed

The following checks are failing:
- <check-name>: fail - <url>

Merge Conflicts:

Merge failed: conflicts detected

Please resolve conflicts manually:
1. git fetch origin
2. git merge origin/main
3. Resolve conflicts
4. Push changes
5. Try merge again

Operation 3: List PRs

List all open pull requests in the current repository.

Workflow

gh pr list --state open

Display the list of open PRs with their numbers, titles, and branch names.

Operation 4: Comment

Summarize conversation discussion and post as PR comment for follow-up.

Arguments

• comment [pr-id] - Post conversation summary to specific PR

Workflow

Step 1: Detect PR Number

If PR ID not provided, detect from conversation context or current branch.

Step 2: Analyze Conversation

Review recent conversation to identify:

• Key discussion points and decisions
• Technical findings or analysis results
• Action items or follow-up tasks
• Recommendations or suggestions
• Open questions requiring input

Step 3: Structure Comment

Organize based on content type (technical memo, follow-up tasks, etc.):

## [Topic from Discussion]

[Summary of key points]

### Action Items
- [ ] Task 1
- [ ] Task 2

### Technical Notes
[If applicable]

Step 4: Post Comment

gh pr comment "$PR_NUMBER" --body "$COMMENT_CONTENT"

Best Practices

1. Always check branch status first - Don't assume the current state
2. Run pre-commit checks - Never skip quality checks
3. Never merge with failing checks - Code quality is non-negotiable
4. Use squash merge - Keeps main history clean
5. Clear fleet delivery labels after merge - Closes #N closes the issue but not its labels; a delivered issue without the label clear stays pickable forever. Only closing keywords (Closes/Fixes/Resolves #N) count — Issue: #N alone never clears labels
6. Confirm merge completion - Verify PR state is MERGED
7. Keep user informed - Clear status at each step
