Issue To Pr Workflow

Issue-to-PR Workflow ⚙️

From open issue to merged PR -- the engineering agent's implementation loop.

Use this skill when you've picked an issue from the patrol queue and need to turn it into working code with a reviewed PR.

Philosophy

• Understand before you build. Read the issue, the codebase, the architecture -- then code.
• Small increments. One issue = one branch = one PR. No scope creep.
• Tests are not optional. New logic gets tests. Period.
• Reviews are respected. When the reviewer says REQUEST_CHANGES, fix it -- don't argue (much).
• Ship results, not status updates. Progress lives in Git, not in chat messages.

Prerequisites

• gh CLI authenticated (gh auth status)
• Write access to the target repo
• Familiarity with github-workflow skill (branch/PR conventions)
• Reviewer configured (default: YyRemy for Yesterday repos)

The Workflow

Phase 1: Understand the Issue

REPO="Yesterday-AI/clawrag"
ISSUE=42

# Read the full issue
gh issue view $ISSUE --repo $REPO --json title,body,labels,assignees,comments

# Check for linked PRs (avoid duplicate work)
gh pr list --repo $REPO --search "closes:#$ISSUE OR fixes:#$ISSUE"

Before writing any code, answer these questions:

1. What exactly needs to change? -- Can you describe the change in one sentence?
2. Where in the codebase? -- Which files/modules are affected?
3. What are the edge cases? -- Empty input? Auth failure? Race conditions?
4. How will you test it? -- Unit test? Integration test? Manual verification?
5. Are there dependencies? -- Does this need another PR to land first?

If you can't answer #1 or #2, the issue needs clarification -- don't start coding.

Phase 2: Prepare the Branch

cd <repo-directory>
git checkout main && git pull --rebase origin main

# Branch naming: type/short-description
# Use the issue number for traceability
git checkout -b feat/issue-42-retry-logic

Branch naming conventions:

Phase 3: Implement

Work loop:

1. Explore -- Read existing code around the change area
2. Plan -- Sketch the approach mentally (or in a comment if complex)
3. Build -- Write the code in small, focused commits
4. Test -- Run tests after each meaningful change
5. Commit -- Conventional Commits, reference the issue

# Good commit messages
git commit -m "feat: add exponential backoff to API client

Implements retry with exponential backoff for transient failures.
Max 3 retries, initial delay 1s, backoff factor 2.

Closes #42"

Implementation rules:

• Follow existing patterns. Match the repo's code style, not your preference.
• No debug artifacts. Remove console.log, print() debugging before commit.
• No secrets. Ever. Not even "as an example". Use placeholders like your-token-here.
• Handle errors. New code paths need error handling. Silent failures are bugs.
• Update docs if needed. Changed an API? Update the README.

Phase 4: Create the PR

# Rebase before pushing
git pull --rebase origin main

# Push
git push origin feat/issue-42-retry-logic

# Create PR with structured body
gh pr create \
  --repo $REPO \
  --title "feat: add exponential backoff to API client" \
  --body "## Context (Why)
Transient API failures cause data loss. Issue #42 reports intermittent 503s
from the upstream service.

## Changes (What)
- Added \`RetryClient\` wrapper with exponential backoff
- Default: 3 retries, 1s initial delay, 2x backoff factor
- Configurable via environment variables

## Outcome (Impact)
API calls survive transient failures without manual intervention.
Error rate expected to drop significantly.

## Testing
- Unit tests for retry logic (happy path + max retries exceeded)
- Integration test with mock 503 responses
- Manual test against staging

Closes #42" \
  --reviewer YyRemy

After creating the PR:

PR_NUMBER=<returned PR number>

# Self-assign
gh api repos/$REPO/issues/$PR_NUMBER/assignees \
  -X POST -f 'assignees[]=YyScotty'

# Label based on type
gh api repos/$REPO/issues/$PR_NUMBER/labels \
  -X POST -f 'labels[]=enhancement'

Phase 5: Notify the Reviewer

Don't rely solely on GitHub notifications. Ping the reviewer directly:

# Via agent messaging (if available)
"Hey Remy, PR #<N> auf <repo> ist ready for review. <one-line summary>"

Phase 6: Handle Review Feedback

When the reviewer submits REQUEST_CHANGES:

# 1. Read the review
gh pr view $PR_NUMBER --repo $REPO --json reviews --jq '.reviews[-1]'

# 2. Read inline comments
gh api repos/$REPO/pulls/$PR_NUMBER/comments \
  --jq '.[] | {id, path, line: .original_line, body}'

# 3. Fix the issues
# ... make changes ...
git add -A && git commit -m "fix: address review feedback

- Added null check per reviewer suggestion
- Improved error message clarity"
git push origin feat/issue-42-retry-logic

# 4. Reply to each comment
gh api repos/$REPO/pulls/$PR_NUMBER/comments/<COMMENT_ID>/replies \
  -X POST -f body="Fixed -- added the null check as suggested."

# 5. Request re-review
gh api repos/$REPO/pulls/$PR_NUMBER/requested_reviewers \
  -X POST -f 'reviewers[]=YyRemy'

Review feedback rules:

• Read every comment. Don't skip any.
• Fix blocking issues immediately. No "I'll do it in a follow-up".
• Disagree respectfully. If you think the reviewer is wrong, explain why -- on the comment thread, not in a new commit message.
• Don't force-push. Regular push so the reviewer can see the incremental diff.
• Ping after fixing. Always request re-review after pushing fixes.

Phase 7: Post-Merge

After the PR is approved and merged (by a human):

# Clean up local branch
git checkout main && git pull origin main
git branch -d feat/issue-42-retry-logic

Update patrol state:

• Set issue to closed in issue-patrol-state.json
• Remove from inProgressQueue

Flowchart

Issue picked from readyToImplementQueue
  │
  ├─ Read issue → Can implement?
  │   ├─ NO → Comment for clarification → Move to needsClarificationQueue
  │   └─ YES ↓
  │
  ├─ Create branch (feat/fix/docs/chore)
  ├─ Implement (small commits, tests, no secrets)
  ├─ Create PR (structured body, reviewer assigned)
  ├─ Notify reviewer
  │
  ├─ Review result?
  │   ├─ APPROVE → Wait for human merge → Clean up
  │   ├─ REQUEST_CHANGES → Fix → Push → Re-request review → Loop
  │   └─ COMMENT → Address if needed → Continue
  │
  └─ Done ✅

Quality Gates (Self-Check Before PR)

Run through this checklist before creating the PR:

• Code does what the issue asks for
• No secrets/credentials anywhere (code, comments, commit messages)
• Tests exist for new/changed logic
• No breaking changes without documentation
• PR description has Context/Changes/Outcome/Testing
• Conventional Commit messages
• No leftover debug code (console.log, print, TODO: remove)
• Rebased on latest main

Common Pitfalls

Integration with Issue Patrol

This skill is the "action" companion to issue-patrol-routine:

1. Patrol classifies issues into queues
2. Agent picks from readyToImplementQueue
3. This workflow executes the implementation
4. Patrol tracks the issue as inProgressQueue via linked PR
5. After merge, patrol marks it closed

Update issue-patrol-state.json when:

• Starting work: set linkedPR + linkedBranch
• PR merged: issue will auto-close if Closes #N is in PR body
