Complete Feature

Feature Completion Workflow

Run this skill when you believe a feature is complete. It runs comprehensive checks across six areas.

Usage

/complete-feature "focus-timer-widget"
/complete-feature "category-ai-classification"

Parallel Dispatch

Phases 1–4 run as three parallel subagents to maximize speed. Dispatch all three simultaneously, then aggregate results before continuing to Phase 5.

Coordinator (you)
├─► Agent A — Build + Test          [Fast tier: claude-haiku-4-5 / gpt-4.1-mini / gemini-3.0-flash]
├─► Agent B — Code Quality          [Standard tier: claude-sonnet-4-6 / gpt-4.1 / gemini-3.1-pro]
└─► Agent C — Accessibility Audit   [Standard tier: claude-sonnet-4-6 / gpt-4.1 / gemini-3.1-pro]
         │
         ▼ (all three complete)
Coordinator — Phase 5: Documentation + Phase 6: App Store Readiness

Checkpoint Compaction

Before aggregating subagent results, before Phase 5 documentation, and before any manual or automatic context reset, write a durable checkpoint in the feature plan, issue, or completion report. Include completed work, remaining steps, changed files, decisions made, verification already run, failures, and the next exact command. After compaction or a new session, re-read the checkpoint and git status before continuing.

Agent A — Build + Test (Fast tier)

Spawn as apple-dev-skills:build-agent (or apple-dev-skills:explore). Prompt:

Run build and test verification for the iOS feature being completed.

1. Debug build (simulator):
   xcodebuild -scheme  -destination 'platform=iOS Simulator,name=iPhone 17 Pro Max' build 2>&1 | grep -E "error:|BUILD SUCCEEDED|BUILD FAILED"

2. Archive build (CRITICAL — catches MainActor isolation errors debug misses):
   xcodebuild -scheme  -configuration Release -destination 'generic/platform=iOS' archive 2>&1 | grep -E "error:|ARCHIVE SUCCEEDED|ARCHIVE FAILED"

3. Unit tests:
    2>&1 | tail -10

Report:
- BUILD: PASS/FAIL + first 3 errors if failed
- ARCHIVE: PASS/FAIL + first 3 errors if failed
- TESTS: X passed, Y failed + failing test names

Agent B — Code Quality (Standard tier)

Spawn as apple-dev-skills:code-reviewer. Prompt:

Run code quality checks on the changed files for this iOS feature.

Changed files: 

1. Apple patterns check — apply the apple-patterns-check skill rules:
   - Force unwraps, try!, fatalError() in production code
   - print() statements not in #if DEBUG
   - Missing @preconcurrency imports for EventKit/ActivityKit/CoreData/AVFoundation/SwiftData/Speech/Vision/HealthKit
   - Task { [weak self] without @MainActor
   - Missing nonisolated deinit on @MainActor classes
   - Hardcoded isAvailable=true for FoundationModels (must use SystemLanguageModel.default.isAvailable)
   - MainActor.assumeIsolated from background queue callbacks
   - @Model properties without default values
   - Sheet onDismiss + continuation double-resume risk

2. Code cleanliness:
   - TODO:/FIXME: without issue links
   - Commented-out code blocks (>5 lines)
   - Dead code (unreachable, unused variables)

Report each issue as: [SEVERITY] File:Line — Description
Severity: CRITICAL | HIGH | MEDIUM

Agent C — Accessibility Audit (Standard tier)

Spawn as apple-dev-skills:code-reviewer. Prompt:

Run accessibility audit on the SwiftUI views changed in this feature.

Changed Swift files with views: 

Apply ios-accessibility skill rules:
1. VoiceOver: .accessibilityLabel on all interactive elements (Button, Toggle, custom controls)
2. Dynamic Type: font(.body) not hardcoded sizes; no fixed frame heights on text containers
3. Reduce Motion: withAnimation guarded by accessibilityReduceMotion where used
4. Color contrast: no color-only distinction for meaning; check against WCAG AA

Report each issue as: [SEVERITY] File:Line — Description
If no views changed, report: N/A

Completion Checklist

1. Build Verification

• [ ] Debug build passes (simulator)
• [ ] Archive build passes -- CRITICAL: catches MainActor isolation errors debug misses
• [ ] No Swift 6 strict concurrency warnings
• [ ] If the app embeds any app extension (.appex): every one carries NSExtension.NSExtensionPointIdentifier -- run verify-appex-infoplist.sh --ipa . Missing it builds & uploads fine but fails Apple's async processing (error 90348) and silently drops from TestFlight. See ios-build → "App Extension Info.plist".

2. Test Verification

• [ ] All unit tests pass
• [ ] New code has corresponding test coverage
• [ ] UI tests pass if views changed

3. Code Quality

Delegate to apple-patterns-check for detailed pattern validation, then verify:

• [ ] No TODO: or FIXME: without issue links
• [ ] No force unwraps, try!, or fatalError() in production code
• [ ] No print() statements in production code

4. Accessibility

Delegate to ios-accessibility for detailed audit, then verify:

• [ ] VoiceOver labels on all interactive elements
• [ ] Dynamic Type support verified
• [ ] Reduce Motion respected
• [ ] Color contrast meets WCAG AA

5. Documentation

• [ ] ADR written if architectural decision made
• [ ] Project roadmap updated with completion status
• [ ] Feature plan moved to completed folder
• [ ] Project documentation updated if patterns changed

6. App Store Readiness (if applicable)

• [ ] App Store Connect metadata updated
• [ ] Screenshots generated if UI changed
• [ ] What's New text drafted
• [ ] Privacy manifest updated if new data collected

Entitlements Audit (common App Store rejection cause):

# All targets sharing data must have the SAME App Group identifier
grep -r "group\."  --include="*.entitlements"

# Verify PrivacyInfo.xcprivacy exists for each extension target
find  -name "PrivacyInfo.xcprivacy" -not -path "*/build/*"

# Verify no unused entitlements
grep -r "com.apple.developer"  --include="*.entitlements"

Post-Completion Actions

After all checks pass:

1. Stage changes: git add -A
2. Commit: Follow conventional commits (feat:, fix:, docs:, etc.)
3. Push: Only after all checks pass

Integration with Other Skills

This skill coordinates with:

• apple-patterns-check — code pattern validation (Phase 3)
• ios-accessibility — VoiceOver/contrast verification (Phase 4)
• verify-against-spec — if the feature was spec-driven, run this first
• merge-check — run after completing, before merging to main
