Dev Finish - Quality Gate & Close

Complete a dev-cycle session: QA Gate → Code Review → Fix Issues → Commit → PR → Learn → Archive

Key principle: We ship quality. The project's own checks must exit 0 first, then Bob and Garry review before we close. Arlo joins when data/analytics are involved.

Agent Roles in Review

• Bob: Code quality, bugs, security, performance, tests
• Garry: Requirements match, architecture, completeness
• Arlo: Data logic, calculations, patterns, analytics accuracy (when applicable)

Flow

1. Find Active Session

ls ~/.claude/dev-cycles/active/ | grep "$(basename $(pwd))"

If no active session:

• "No active dev-cycle found for this project. Nothing to finish."
• Exit

If found:

• Read session file
• Show summary of what was done

2. Generate Diff for Review

Save the full diff to a file for thorough review:

# Create review directory if needed
mkdir -p ~/.claude/dev-cycles/reviews

# Get project and branch info
PROJECT=$(basename $(pwd))
BRANCH=$(git branch --show-current)
TIMESTAMP=$(date +%Y%m%d-%H%M%S)

# Save full diff to file
git diff main...HEAD > ~/.claude/dev-cycles/reviews/${PROJECT}--${BRANCH}--${TIMESTAMP}.diff

# Also save stat summary
git diff main...HEAD --stat > ~/.claude/dev-cycles/reviews/${PROJECT}--${BRANCH}--${TIMESTAMP}.stat

Present summary to the user:

• Files changed
• Lines added/removed
• Diff saved to: {path}

3. QA Gate (objective, runs first)

Run the checks before any opinion. Use the dev-qa skill: the project's own tests, linter, type checker and build. Pass = exit code 0. Not "looks fine" — zero.

If anything exits non-zero:

QA gate failed:
- tests: exit 1 (2 failures)
- lint: exit 0
- build: exit 0

Options:
1. Fix now (Bob fixes, then the gate runs again)
2. Fix manually, then run /dev-finish again
3. Abandon this session

This skill does not offer to commit while the gate is red. If the user wants to ship a red build anyway, they can commit by hand — that is their call to make, not this skill's to offer.

If the project has no tests or checks, say so explicitly ("QA gate: nothing to run — no test suite found") and record Review Status: no-checks in the session file. Loop until the gate is green, then move to review.

4. Code Review

Checks prove it runs. Review checks it's right.

Step 1: Bob Reviews Code Quality

Delegate to Bob:

"Bob, review this diff file: {diff-path}

Check for:
- Code quality and readability
- Potential bugs or edge cases
- Security issues
- Performance concerns
- Missing error handling
- Test coverage gaps

Be thorough. List issues by severity:
- CRITICAL: Must fix before merge
- WARNING: Should fix
- SUGGESTION: Nice to have"

Step 2: Arlo Reviews Data Logic (if applicable)

Include Arlo when the session involves data/analytics/numbers.

Check session file for Involves Data/Analytics: yes or detect from diff:

• Database queries, aggregations
• Calculations, statistics
• Charts, dashboards, reports
• Data transformations
• Financial logic

If data is involved, delegate to Arlo:

"Arlo, review the data/analytics aspects of this diff: {diff-path}

Check for:
- Data logic correctness
- Edge cases: nulls, zeros, negatives, empty sets
- Calculation accuracy
- Aggregation logic
- Query efficiency and correctness
- Numbers telling the right story
- Pattern detection logic (if any)

List issues by severity:
- CRITICAL: Data bug, wrong calculations
- WARNING: Edge case not handled
- SUGGESTION: Could be more efficient"

Step 3: Garry Validates Completeness

Then delegate to Garry:

"Garry, review Bob's findings{, Arlo's findings,} and the diff: {diff-path}

Validate:
- Does this match the original requirements from the session?
- Any architectural concerns?
- Anything the reviewers missed?
- Is this ready to ship?"

5. Address Review Findings

If CRITICAL or WARNING issues found:

Code review found issues:

CRITICAL:
- [Issue 1]
- [Issue 2]

WARNING:
- [Issue 3]

Options:
1. Fix issues now (Bob will fix, then re-review)
2. Fix issues manually, then run /dev-finish again
3. Abandon this session

If "Fix issues now":

• Bob fixes each issue
• Re-run the QA gate and review on the new diff
• Loop until clean

If review passes:

• "QA gate green, code review passed. Ready to commit."

6. Commit Question

Ask the user:

Ready to commit these changes?

Options:
1. Yes, single commit with message I'll provide
2. Yes, help me write the commit message
3. Yes, multiple commits (per logical change)
4. No, leave uncommitted
5. Already committed during build

If committing:

• Follow commit conventions from branch-workflow
• NO Co-Authored-By lines (no AI attribution in commits)
• Use conventional commit format

7. Pull Request Question

Ask the user:

Create a Pull Request?

Options:
1. Yes, create PR now (I'll help write description)
2. Yes, create PR with message I'll provide
3. No, just push the branch
4. No, don't push anything

If creating PR:

# Push branch first
git push -u origin $(git branch --show-current)

# Create PR
gh pr create --title "{title}" --body "{body}"

PR body template:

## Summary
{Brief description of changes}

## Changes
{Key changes from git diff --stat}

## Testing
{How this was tested}

## Review Notes
{Any context for reviewers}

---
Dev cycle session: {session-file}

8. Learning Extraction

Analyze the session:

1. Read the session file (discoveries, decisions, blockers)
2. Look at the git diff
3. Review findings from Bob/Garry
4. Consider what went well/poorly

Ask the user:

Let's capture what we learned. I noticed:

- [Observation 1 from session/diff/review]
- [Observation 2]
- [Observation 3]

Questions:
1. What worked well in this session?
2. Any gotchas or things to avoid next time?
3. Any patterns worth remembering?

Which learnings should I save?
- Project-specific → goes to .megg/knowledge.md
- General (applies everywhere) → goes to ~/.megg/knowledge.md

For each learning, use megg:

mcp__megg__learn with:
- title: Short descriptive title
- type: decision | pattern | gotcha | context
- topics: [relevant tags]
- content: The learning in markdown
- path: Project path for project-specific, or home for global

9. Archive Session

Move session to completed:

mv ~/.claude/dev-cycles/active/{session-file} ~/.claude/dev-cycles/completed/

Update session file with completion metadata:

## Completion
- **Finished**: {timestamp}
- **Final Branch**: {branch-name}
- **Commits**: {commit hashes or "uncommitted"}
- **PR**: {PR URL or "none"}
- **Review Status**: passed | passed-with-warnings | no-checks | skipped
- **Learnings Captured**: {count}
- **Final Status**: completed | partial | abandoned

## Code Review Summary
{Summary of Bob/Garry findings and resolutions}

## Git Summary
{Output of git diff --stat}

## Learnings Saved
1. [Project] "JWT refresh token pattern" - pattern
2. [Global] "Always test auth flows in isolation" - pattern

Clean up review files:

rm ~/.claude/dev-cycles/reviews/${PROJECT}--${BRANCH}--*.diff
rm ~/.claude/dev-cycles/reviews/${PROJECT}--${BRANCH}--*.stat

10. Final Summary

Present to the user:

Dev cycle complete!

Summary:
- Session: {description}
- Duration: {start} to {end}
- Branch: {branch}
- Changes: {files changed}, {lines added/removed}
- QA gate: {green (all exit 0) / no-checks}
- Review: {passed/passed-with-warnings}
- Commits: {commit info}
- PR: {PR URL or "not created"}
- Learnings: {count} captured ({N} project, {M} global)

Session archived to ~/.claude/dev-cycles/completed/

Edge Cases

Partial Completion

If not all tasks done:

• Ask: "Not all tasks completed. Finish anyway or continue working?"
• If finish: Still do full review, mark status as "partial"
• If continue: Stay in dev-cycle, don't archive

Review Finds Major Issues

If review finds architectural problems:

• Stop and discuss with the user
• May need to revisit the plan
• Option to abandon and start fresh

No Changes Made

If git shows no changes:

• Skip the QA gate and code review (nothing to check)
• Skip commit/PR questions
• Still capture learnings (discovery learnings are valuable)
• Archive normally

Already Has PR

If PR already exists for this branch:

gh pr view --web  # Show existing PR

• Skip PR creation
• Ask if want to update PR description
