Work On Issues

Work on Issues

Autonomous workflow: fetch triaged GitHub issues, pick the best candidate, implement changes in an isolated git worktree, and submit for review.

Prerequisites

• gh CLI authenticated with repo access
• Git worktrees supported (standard git)
• Repository has labels: triaged, priority:must/should/could, size:xs/s/m/l/xl, in-progress

Workflow

Step 1 — Fetch triaged issues

gh issue list --label "triaged" --state open --json number,title,labels,body,comments --limit 50

Skip any issue that:

• Does not have the triaged label (another agent handles triage)
• Already has in-progress label
• Has duplicate or wontfix or auto-dismissed label

Step 2 — Select the best issue

Rank by priority descending, then size ascending:

Score = priority_weight × 10 − size_weight. Pick the highest score. On tie, pick the lowest issue number (oldest).

Step 3 — Claim the issue

Create the in-progress label if it doesn't exist, then apply it:

gh label create "in-progress" --description "Being worked on by an agent" --color "1D76DB" --force
gh issue edit <NUMBER> --add-label "in-progress"

Step 4 — Deep-read the issue

1. Fetch issue body and all comments:

   gh issue view <NUMBER> --json body,comments,title,labels
   

2. Read all referenced files, related source code, and tests in the repository
3. Understand the UX intent, software design goals, and how this fits the product's USP (murmur = cron daemon for Claude Code, minimal building-block philosophy)
4. If the issue references other issues, read those too

Step 5 — Plan the implementation

Think through:

• What files need to change and why
• How to keep changes clean, readable, and minimal (Boy Scout Rule)
• Whether /effect-ts-patterns guidance applies
• What tests to add or update
• Potential edge cases

Do NOT start coding until the plan is solid.

Step 6 — Create a git worktree

Branch name: issue-<NUMBER>-<slug> where slug is a kebab-case summary (max 50 chars).

git worktree add -b "issue-<NUMBER>-<slug>" ../murmur-issue-<NUMBER> main
cd ../murmur-issue-<NUMBER>

Run bun install in the worktree.

Step 7 — Implement the changes

• Follow CLAUDE.md conventions (Bun, Conventional Commits, semantic naming)
• Use /effect-ts-patterns when writing Effect-TS code
• Write or update tests as needed
• Run bun test src/ after changes to verify unit tests pass
• Run bun run build to verify the build succeeds
• Run bun test test/ to verify e2e tests pass (requires the binary from the build step)

Step 8 — Commit with conventional format

git add <specific-files>
git commit -m "<type>(scope): <description>

Closes #<NUMBER>"

Step 9 — Run final review

Execute /final-review to get a comprehensive PR review and ensure quality gates pass.

Step 10 — Push and create PR

git push -u origin issue-<NUMBER>-<slug>

Create PR referencing the issue:

gh pr create --title "<type>(scope): <description>" --body "Closes #<NUMBER>

## Summary
<bullet points>

## Test plan
<checklist>"

Step 11 — Clean up on failure

If any step fails irrecoverably:

1. Remove in-progress label: gh issue edit <NUMBER> --remove-label "in-progress"
2. Add a comment explaining what went wrong: gh issue comment <NUMBER> --body "<explanation>"
3. Remove the worktree: git worktree remove ../murmur-issue-<NUMBER>

Important Notes

• This skill delegates to /effect-ts-patterns and /final-review — it does not reimplement them
• Never force-push or rewrite history on shared branches
• If the issue is ambiguous, leave a clarifying comment and move to the next candidate
• One issue at a time — finish or abandon before picking the next
