Summary

Major refactor of the Swift Engineering plugin to create ultra-specialized agents with clear boundaries and handoff patterns.

Key Changes

  • Commands renamed (drop swift- prefix): /feature, /plan, /test, /build
  • New commands: /review, /modernize
  • TCA split: tca-architect (design, Opus) + tca-engineer (implementation, Sonnet)
  • New agents: swift-code-reviewer, swift-modernizer
  • Model optimization: Opus for planning, Sonnet for implementation, Haiku for builds
  • Planning agents are READ-ONLY - no file modifications
  • Each agent has clear identity statement and handoff table
  • 2025 context added to all agents for API research
  • programming-swift removed from defaults - loaded on-demand only

Full Implementation Plan

Swift Engineering Plugin Refactor Plan

Goals

  • Ultra-specialized agents with clear handoff boundaries
  • Commands without swift- prefix: /feature, /plan, /test, /build
  • Agents with domain prefix: @swift-architect, @swift-engineer, etc.
  • Add "Current Year: 2025" to planning agents for research
  • Clear @agent-name references with WHY rationale in commands
  • Optimize model selection: Opus for planning, Sonnet for implementation, Haiku for mechanical work
  • Remove programming-swift from defaults, specify when to use it
  • Planning agents must NOT make any file changes (read-only)
  • Each agent must clearly specify when to hand off to other agents

Command Changes

Rename Commands (drop swift- prefix)

Old Name New Name File
/swift-feature /feature commands/feature.md
/swift-plan /plan commands/plan.md
/swift-test /test commands/test.md
/swift-build /build commands/build.md
(new) /review commands/review.md
(new) /modernize commands/modernize.md

Command Content Updates

Each command must:

  1. Explain WHY each agent is called
  2. Specify the plan file format inline (instead of separate skill)
  3. Reference agents with @agent-name syntax
  4. Clearly define agent boundaries - what triggers the next agent
  5. Specify decision logic - how to choose between agents based on previous step

  • When to Hand Off table

For IMPLEMENTATION agents (sonnet/haiku model, can write):

  • Tools: Read, Write, Edit, Glob, Grep, Bash
  • Identity section with Mission and Goal
  • Context section with Current Year: 2025
  • When to Hand Off table
  • programming-swift usage guidance (load on-demand only)

Skill Assignment (Optimized)

Agent Skills Notes
@swift-architect ios-hig, composable-architecture (index), sqlite-data (index) Opus - needs breadth
@swift-ui-design ios-hig UI focus only
@tca-architect composable-architecture TCA design patterns
@tca-engineer composable-architecture, swift-style TCA implementation
@swift-engineer sqlite-data, swift-style Vanilla Swift
@swiftui-specialist ios-hig, swift-style Views only
@swift-test-creator swift-testing Creates tests only (doesn't run)
@swift-builder (none) Just runs builds
@swift-documenter generating-swift-package-docs Docs only
@swift-code-reviewer ios-hig, swift-style Review patterns
@swift-modernizer programming-swift Needs language ref

Note: programming-swift removed from all defaults. Agents know to load it when:

  • Verifying obscure Swift syntax
  • Checking language semantics (actor isolation, generics)
  • Resolving compiler errors related to language features

Code Review: Ultra-Specialized Agent Refactor

Summary

This is an excellent refactor that transforms the Swift Engineering plugin into a well-architected, specialized agent system. The separation of concerns, clear handoff patterns, and model optimization are particularly well done. The implementation demonstrates strong software architecture principles and should significantly improve the user experience.

Overall Assessment:Approved with minor suggestions


🎯 Strengths

1. Exceptional Architecture Design

  • Clear separation of concerns: Planning agents (Opus, read-only) vs implementation agents (Sonnet) vs mechanical work (Haiku)
  • Agent specialization: Each agent has a single, well-defined responsibility
  • Handoff tables: Every agent clearly documents when and why to transfer to another agent
  • Model optimization: Intelligent use of Opus for planning, Sonnet for implementation, Haiku for builds

2. Excellent Documentation

  • Comprehensive README with clear workflow diagrams
  • Each agent has an "Identity" section with Mission and Goal
  • "When to Hand Off" tables prevent confusion
  • Plan file format standardization enables consistent state sharing

3. Strong Quality Patterns

  • READ-ONLY enforcement for planning agents (prevents premature implementation)
  • TCA split into architect (design) and engineer (implementation)
  • "Current Year: 2025" context for API research
  • Removal of programming-swift from defaults (load on-demand only)
  • Self-evaluation prompts in agents

4. Well-Designed Commands

  • Clear naming (dropped swift- prefix for cleaner UX)
  • Commands explain WHY each agent is called
  • Semi-guided vs fully automated workflow options
  • Inline plan file format specifications

🔍 Issues & Suggestions

CRITICAL Issues: 0

Important Issues: 2

1. [Consistency] Missing Bash tool in swiftui-specialist agent

File: plugins/swift-engineering/agents/swiftui-specialist.md:4

Issue: The swiftui-specialist agent has tools defined as Read, Write, Edit, Glob, Grep but is missing Bash, which other implementation agents have.

Why it matters: The agent may need to run git commands, check file status, or perform other shell operations. All other implementation agents include Bash.

Fix:

-tools: Read, Write, Edit, Glob, Grep
+tools: Read, Write, Edit, Glob, Grep, Bash

Justification: Consistency with other implementation agents (swift-engineer, tca-engineer, swift-test-creator).


2. [Documentation] Self-evaluation question inconsistency

Files: Multiple agent files

Issue: Most agents use "Have I done the best possible work I can?" but some use more specific questions like "Is the build clean?" or "Have I followed the TCA Design exactly?"

Why it matters: The generic question is less actionable than specific criteria. More specific self-evaluation leads to better quality control.

Examples:

  • swift-architect.md:163: Good - "Have I provided enough detail for implementation agents?"
  • tca-engineer.md:176: Excellent - "Have I followed the TCA Design exactly? Is the code production-ready?"
  • swift-builder.md:123: Excellent - "Is the build clean?"
  • swiftui-specialist.md:104: Generic - "Have I done the best possible work I can?"

Suggestion: Update all agents to use specific, measurable self-evaluation criteria rather than the generic question.


Suggestions: 4

1. [Enhancement] Add test coverage guidance

Context: Neither swift-test-creator nor the plan file format includes coverage metrics.

Suggestion: Consider adding a coverage expectation section to the plan file format:

## Test Strategy
- **Target coverage:** 80%+ for reducers, 60%+ overall
- **Key behaviors to test:** [List]
- **Edge cases:** [List]

This helps set expectations and measure test completeness.


2. [Documentation] Clarify "programming-swift" on-demand loading

Files: Multiple agent files mention loading programming-swift on-demand

Issue: The guidance is consistent but could be more explicit about HOW to load it.

Suggestion: Add a brief note in agent files:

## programming-swift Usage

Load `programming-swift` skill ONLY when:
- Verifying obscure Swift syntax
- Checking language semantics (e.g., actor isolation rules)
- Resolving compiler errors related to language features

**To load:** Add "Read the programming-swift skill for [specific question]" in your prompt.

3. [Workflow] Consider adding error budget to agents

Context: swift-builder has a "3 attempts" rule before escalating, but other agents don't have explicit failure handling.

Suggestion: Consider adding an error budget section to implementation agents:

## Error Handling
- Attempt fixes up to 2 times
- On third failure, escalate to appropriate agent or user
- Document all failures in handoff notes

This prevents infinite loops and clarifies when to ask for help.


4. [Performance] Plan file update frequency

Context: Agents are instructed to update the plan file "before returning to main."

Consideration: For long-running implementations, the plan file might not reflect in-progress status if the agent hasn't completed.

Suggestion: Consider adding guidance for progress updates during long-running work:

## Progress Updates

For implementations taking >5 file changes:
- Update handoff notes in the plan file after each major milestone
- This helps other agents if handoff happens mid-implementation

🎨 Code Quality Assessment

Best Practices: ✅

  • Excellent use of YAML frontmatter for agent metadata
  • Consistent Markdown formatting throughout
  • Clear code examples in agent documentation
  • Proper use of Swift 6.2 features (async/await, Sendable, etc.)

Maintainability: ✅

  • Modular agent design makes updates easy
  • Clear naming conventions
  • Comprehensive handoff tables reduce coupling
  • Plan file provides shared state without tight coupling

Testing Considerations: ✅

  • swift-testing skill integration
  • TestStore patterns for TCA
  • Clear separation of test creation vs test execution
  • Emphasis on testing core logic, not framework internals

🔒 Security Review

✅ Good Security Practices

  1. @swift-code-reviewer explicitly checks for:

    • Hardcoded secrets
    • Input validation
    • Keychain usage for credentials
    • Privacy manifest entries
    • Secure networking (HTTPS)
  2. Logging guidance in agents:

    • "Never log secrets, PII, or tokens"
    • Use os.Logger with appropriate categories
  3. Privacy-first architecture:

    • Local-first defaults (SQLite, UserDefaults)
    • No backend unless requested
    • Privacy manifest considerations

No Security Issues Found ✅


📊 Performance Considerations

✅ Strong Performance Design

  1. Model selection optimization:

    • Opus for complex planning (worth the cost)
    • Sonnet for implementation (balanced)
    • Haiku for mechanical work (fast and cheap)
  2. Skill loading strategy:

    • Removed heavy skills from defaults
    • On-demand loading reduces context size
    • 37K+ line programming-swift skill loaded only when needed
  3. Agent specialization:

    • Focused agents complete tasks faster
    • Clear boundaries prevent unnecessary work
    • Handoff patterns avoid redundant analysis

Potential Optimization

Context size management: Multiple agents reading the same plan file could lead to context bloat if files get large. Consider adding guidance:

## Plan File Best Practices
- Keep handoff notes concise (3-5 sentences per agent)
- Archive old handoff entries after completion
- Use bullet points over paragraphs

🧪 Test Coverage Assessment

Test Plan in PR Description: ✅ Comprehensive

The test plan covers:

  • ✅ Command verification (/feature, /plan, /test, /build, /review, /modernize)
  • ✅ Read-only enforcement for planning agents
  • ✅ Write permissions for implementation agents
  • ✅ Model verification (@swift-builder uses Haiku)
  • ✅ Agent handoff verification

Suggestion: Consider adding integration tests:

  • End-to-end workflow test (UI design → implementation → tests → build)
  • Error handling test (what happens when an agent fails?)
  • Plan file state consistency test

📝 Documentation Quality

README.md: ⭐⭐⭐⭐⭐

Strengths:

  • Clear workflow diagram (ASCII art)
  • Agent handoff model table
  • Plan file format example
  • Architecture conventions
  • Model usage rationale

Minor enhancement: Could add a "Quick Start" section for new users:

## Quick Start

1. Install Sosumi MCP server (required)
2. Run `/feature` to create your first Swift feature
3. Choose "fully automated" for hands-off workflow
4. Review generated code in `Features/<FeatureName>/`

Agent Documentation: ⭐⭐⭐⭐⭐

Exceptional quality:

  • Identity sections are clear and motivating
  • Responsibilities are explicit (MUST Do / MUST NOT Do)
  • Code examples are practical and correct
  • Handoff tables prevent workflow confusion

🎯 Recommendations

High Priority

  1. ✅ Fix swiftui-specialist missing Bash tool
  2. ✅ Standardize self-evaluation questions across agents

Medium Priority

  1. Consider adding test coverage guidance
  2. Consider adding error budgets to agents

Low Priority (Nice to Have)

  1. Add "Quick Start" section to README
  2. Add plan file size management guidance
  3. Consider adding progress update guidance for long-running work

Final Verdict

This PR is ready to merge. The two important issues are minor consistency fixes that don't block functionality. The suggestions are enhancements for future consideration.

Why this is excellent work:

  1. Architectural excellence: The separation of planning vs implementation, the agent specialization, and the handoff patterns show deep understanding of agent system design.

  2. User experience focus: The semi-guided vs fully automated options, the clear WHY explanations, and the comprehensive documentation make this very usable.

  3. Performance optimization: Intelligent model selection and skill loading show cost-consciousness and performance awareness.

  4. Maintainability: The modular design makes it easy to add new agents or modify existing ones without breaking the system.

  5. Quality focus: Read-only enforcement, self-evaluation prompts, and code review integration demonstrate commitment to quality.

Impact: This refactor transforms the plugin from a basic workflow tool into a sophisticated agent orchestration system. It should significantly improve success rates for Swift development tasks.


Commit Recommendation

Once the two consistency issues are addressed (or accepted as-is), this is ready to merge.

Great work on this refactor! 🎉

It should ask if the user wants tests to be written. If the answer is no, proceed to asking the user if they want to document (phase 8)

## Summary
- Created `modern-swift` skill with Swift 6.2 concurrency essentials
- Created `modern-swiftui` skill with iOS 17+ SwiftUI patterns
- Added `modern-swift` to all 11 agents for consistent concurrency patterns
- Added `modern-swiftui` to 4 UI-focused agents (swift-ui-design, swiftui-specialist, swift-code-reviewer, swift-modernizer)
- Updated README.md with new skills documentation

## Skills Content

**modern-swift:**
- async/await (no completion handlers)
- @mainactor (no DispatchQueue.main)
- Actor isolation (no locks)
- Sendable conformance
- TaskGroup (no DispatchGroup)

**modern-swiftui:**
- @observable (replaces ObservableObject)
- @State (replaces @StateObject)
- @bindable (replaces @ObservedObject)
- environment(_:) (replaces environmentObject)
- onChange(of:initial:_:) new signature
- task(priority:_:) for async work

## Why

Without essential Swift knowledge loaded by default, agents might use deprecated patterns. These condensed skills ensure all agents follow modern Swift 6.2 and iOS 17+ best practices.

Summary

This is an excellent refactoring that transforms the Swift Engineering plugin into a well-architected, ultra-specialized agent system. The separation of concerns, clear handoff boundaries, and model optimization (Opus for planning, Sonnet for implementation, Haiku for builds) are particularly well done. The addition of modern-swift and modern-swiftui skills ensures agents follow current best practices.

Overall Assessment:Ready to merge with minor suggestions for improvement.


Strengths

[PRAISE] Agent Architecture

The split between planning (read-only, Opus) and implementation (write-enabled, Sonnet) agents is brilliant:

  • Clear boundaries: Each agent knows exactly when to hand off
  • READ-ONLY enforcement: Planning agents (swift-architect, tca-architect) explicitly cannot modify files
  • TCA separation: Splitting TCA into architect + engineer properly separates design from implementation
  • Handoff tables: Every agent has a clear "When to Hand Off" table

[PRAISE] Skills Design

The modern-swift and modern-swiftui skills are exceptionally well-crafted:

plugins/swift-engineering/skills/modern-swift/SKILL.md
plugins/swift-engineering/skills/modern-swiftui/SKILL.md
  • Concise, actionable patterns
  • Clear ✅ Modern vs ❌ Deprecated examples
  • Covers critical Swift 6.2 and iOS 17+ patterns
  • Perfect reference for ensuring agents use current APIs

[PRAISE] Command Design

The /feature command workflow is comprehensive and well-documented:

plugins/swift-engineering/commands/feature.md:46-223
  • Clear phase-by-phase workflow
  • Decision points explicitly documented
  • Semi-guided vs fully-automated modes
  • WHY explanations for each agent handoff

[PRAISE] Documentation Quality

The README.md provides excellent overview:

plugins/swift-engineering/README.md:1-177
  • Clear agent categorization (Planning/Implementation/Mechanical)
  • Comprehensive handoff table
  • Plan file format inline documentation
  • Model usage rationale

Important Issues

[IMPORTANT] iOS 26.0 Future Dating

Files: Multiple agents and README
Problem: The codebase references iOS 26.0+ as the target, but as of 2025-12-20, iOS 26 doesn't exist yet. Current iOS version is iOS 18.x (2024) with iOS 19 likely in 2025.

Examples:

  • plugins/swift-engineering/README.md:9: "iOS 26+ / Swift 6.2"
  • plugins/swift-engineering/agents/swift-architect.md:27: "iOS 26.0+, Swift 6.2+, Strict concurrency"

Fix: Update to realistic versions:

# Before
**Platform:** iOS 26.0+, Swift 6.2+, Strict concurrency

# After
**Platform:** iOS 17.0+, Swift 6.0+, Strict concurrency

Impact: This affects all agent context sections. iOS 17 is appropriate for @Observable support (required by modern-swiftui skill).


[IMPORTANT] Inconsistent Plan File Status Items

File: Multiple commands and agents
Problem: Different agents reference different status checklist items in the plan file format.

Example 1 - feature.md:

plugins/swift-engineering/commands/feature.md:23-32
- [ ] UI design (@swift-ui-design)
- [ ] Architecture (@swift-architect)
- [ ] TCA design (@tca-architect) — if TCA
- [ ] Implementation (@tca-engineer or @swift-engineer)
- [ ] Views (@swiftui-specialist)
- [ ] Code review (@swift-code-reviewer) — optional
- [ ] Tests (@swift-test-creator)
- [ ] Build verified (@swift-builder)
- [ ] Documentation (@swift-documenter) — optional

Example 2 - swift-architect.md:

plugins/swift-engineering/agents/swift-architect.md:100-109
- [ ] UI design analysis (@swift-ui-design) — if applicable
- [x] Planning complete (@swift-architect)
- [ ] TCA design (@tca-architect) — if TCA
- [ ] Core implementation (@tca-engineer or @swift-engineer)
- [ ] SwiftUI views (@swiftui-specialist)
- [ ] Code review (@swift-code-reviewer) — optional
- [ ] Tests (@swift-test-creator)
- [ ] Build verified (@swift-builder)
- [ ] Documentation (@swift-documenter) — if needed

Fix: Standardize the status checklist across all files. Consider creating a single source of truth in a shared template.


[IMPORTANT] Missing Error Handling Guidance

Files: Agent implementation guides
Problem: Neither swift-engineer.md nor tca-engineer.md provide clear guidance on error handling patterns, despite mentioning "domain-specific error types."

Current state in swift-engineer.md:

plugins/swift-engineering/agents/swift-engineer.md:64-68
### Error Handling
- Domain-specific error types
- Typed throws (Swift 6.2)
- Handle errors at appropriate boundaries

Suggestion: Add concrete examples:

// Domain-specific error types
enum UserProfileError: Error {
    case invalidEmail
    case networkFailure(Error)
    case unauthorized
}

// Typed throws (Swift 6.0+)
func loadProfile() async throws(UserProfileError) -> UserProfile {
    // Implementation
}

// Handle at boundaries
func refreshProfile() async {
    do {
        let profile = try await loadProfile()
        self.profile = profile
    } catch let error as UserProfileError {
        self.error = error.localizedDescription
    }
}

Suggestions

[SUGGESTION] Agent Identity Consistency

Files: All agent files
Observation: Some agents have strong identity statements, others are minimal.

Best example:

plugins/swift-engineering/agents/swift-architect.md:13-16
You are **@swift-architect**, an expert iOS/Swift software architect.

**Mission:** Design Swift feature architectures that are maintainable, testable, and follow Apple best practices.
**Goal:** Produce a comprehensive plan that implementation agents can follow without ambiguity.

Weaker example:

plugins/swift-engineering/agents/swift-builder.md:11-16
You are **@swift-builder**, an expert in Xcode builds and compiler error resolution.

**Mission:** Build the project and resolve compiler errors efficiently.
**Goal:** Achieve a clean build with no errors or warnings.

Suggestion: Ensure all agents have equally strong identity/mission/goal statements. The swift-builder example is actually good, but ensure consistency across all 11 agents.


[SUGGESTION] Plan File Location Convention

Files: Commands and agents
Observation: Plan files use docs/plans/<feature-name>.md but no guidance on feature name normalization.

Current:

plugins/swift-engineering/commands/feature.md:18
All agents share state via a plan file at `docs/plans/<feature-name>.md`:

Suggestion: Add explicit naming conventions:

## Plan File Naming

Format: `docs/plans/<feature-name>.md`

Conventions:
- Use kebab-case: `user-profile.md` (NOT `UserProfile.md` or `user_profile.md`)
- Match feature name: `UserProfile` feature → `user-profile.md`
- Descriptive: `shopping-cart.md`, not `cart.md` or `feature-1.md`

[SUGGESTION] Skill Loading Optimization

Files: All agents
Observation: Some agents load skills they may not need frequently.

Example - swift-architect.md:

plugins/swift-engineering/agents/swift-architect.md:6
skills: modern-swift, ios-hig, composable-architecture, sqlite-data

Suggestion: The architect loads sqlite-data but only for persistence decisions (infrequent). Consider documenting when to load skills on-demand vs default loading, similar to how programming-swift is handled:

plugins/swift-engineering/agents/swift-architect.md:88-92
## programming-swift Usage

Load `programming-swift` skill ONLY when:
- Verifying obscure Swift syntax
- Checking language semantics (e.g., actor isolation rules)
- This skill is 37K+ lines - use sparingly

Could apply similar guidance for other large skills.


[SUGGESTION] Test Coverage Expectations

Files: swift-test-creator.md, /test command
Observation: No explicit guidance on test coverage expectations or what "comprehensive" means.

Suggestion: Add test coverage guidelines to swift-test-creator.md:

## Test Coverage Expectations

Aim for meaningful coverage, not 100% for its own sake:

**Always test:**
- Public API surface
- Business logic and domain rules
- Error handling paths
- State transitions (especially in TCA reducers)

**Consider skipping:**
- Simple property getters/setters
- UI layout code without logic
- Generated code

**Coverage targets:**
- Critical features: 80%+ coverage
- Standard features: 60%+ coverage
- UI components: Focus on behavior, not rendering

[SUGGESTION] Modernize Command Missing Details

File: plugins/swift-engineering/commands/modernize.md
Observation: The /modernize command is well-structured but could benefit from a decision tree for common migrations.

Current: Lists migrations but no prioritization
Suggestion: Add migration priority guidance:

## Migration Priority

When multiple modernization opportunities exist:

1. **Safety first:** Concurrency issues (completion handlers → async/await)
2. **Platform alignment:** SwiftUI adoption (ObservableObject → @Observable)
3. **Maintainability:** TCA adoption (if appropriate)
4. **Cleanup:** Deprecated APIs, old patterns

**Why this order:**
- Concurrency bugs are the hardest to diagnose
- Modern SwiftUI reduces boilerplate significantly
- TCA is architectural (bigger decision)
- Cleanup has lowest risk

Security Considerations

✅ No Security Issues Found

  • No hardcoded secrets or API keys in examples
  • Proper privacy manifest guidance (swift-architect.md:119)
  • Keychain usage mentioned in code review checklist (swift-code-reviewer.md:65)
  • Logging safety emphasized (swift-engineer.md:74: "Never log secrets, PII, or tokens")

Performance Considerations

✅ Well Optimized

  • Model selection: Opus for planning (better decisions), Sonnet for implementation (balanced), Haiku for builds (fast)
  • Skill loading: programming-swift marked as on-demand only (37K+ lines)
  • Agent specialization: Narrow responsibilities prevent bloated prompts
  • Concurrency patterns: modern-swift skill enforces async/await over callbacks

One enhancement suggestion:
Consider documenting estimated token usage for each agent to help users understand costs. Example:

## Agent Token Usage (Estimated)

| Agent | Typical Usage | Why |
|-------|---------------|-----|
| @swift-architect | 15-25K tokens | Large context (skills + planning) |
| @tca-engineer | 8-15K tokens | Medium context (implementation) |
| @swift-builder | 3-8K tokens | Small context (Haiku model) |

Test Coverage Assessment

Status: ⚠️ No tests included in PR

Observation: This is a plugin/configuration change, not executable code, so traditional unit tests don't apply. However, consider:

[SUGGESTION] Add Integration Test Plan:

## Manual Testing Checklist

Before release, verify:
- [ ] `/feature` command executes full workflow
- [ ] Planning agents (Opus) cannot write files (verify with test command)
- [ ] TCA architect → TCA engineer handoff preserves context
- [ ] `@swift-builder` uses Haiku model (check logs)
- [ ] Skills load correctly (modern-swift, modern-swiftui)
- [ ] Plan file format is consistent across agents
- [ ] MCP server (Sosumi) lookup works in all agents

Test with sample feature: "Add a user profile screen with TCA"

Code Quality & Best Practices

✅ Excellent Structure

  • Clear YAML frontmatter for agent metadata
  • Consistent markdown formatting
  • Comprehensive documentation
  • Good use of tables for readability
  • Code examples are clear and realistic

✅ Naming Conventions

  • Agent names: @swift-architect, @tca-engineer (consistent prefix, clear role)
  • Command names: /feature, /plan, /test (no prefix, concise)
  • Skill names: modern-swift, composable-architecture (kebab-case, descriptive)

[SUGGESTION] Add Version/Changelog

Observation: No version tracking for the plugin itself.

Suggestion: Add to README.md:

## Version

**Current:** 2.0.0

### Changelog

#### 2.0.0 (2025-12-20)
- Major refactor: Ultra-specialized agents with clear handoffs

Code Review: Ultra-Specialized Agents Refactor

Summary

This is an excellent refactor that dramatically improves the plugin's architecture through clear separation of concerns, optimized model usage, and well-defined agent boundaries.

Verdict:Ready to merge with minor suggestions for enhancement.


Strengths

🎯 Architecture & Design

[PRAISE] Agent Specialization Model
The split between planning (Opus, read-only) and implementation (Sonnet) agents is brilliant:

  • Clear separation of concerns prevents scope creep
  • Model optimization is cost-effective
  • READ-ONLY enforcement for planning agents prevents premature implementation

[PRAISE] Handoff Model
The explicit handoff tables in each agent are outstanding:

  • Agents know exactly when to hand off
  • Conditional handoffs based on architecture decisions (TCA vs vanilla)
  • Prevents circular dependencies and ambiguity

[PRAISE] Plan File as Shared State
Using docs/plans/<feature>.md as the single source of truth with handoff logs is elegant.

[PRAISE] Documentation Quality
Agent Identity sections, workflow diagrams, and "Current Year: 2025" context awareness are all excellent.


Code Quality Analysis

✅ Best Practices Followed

  1. Consistent Structure - All agents follow the same template
  2. Clear Boundaries - Each agent explicitly states what it MUST and MUST NOT do
  3. Tool Restrictions - Planning agents correctly limited to Read/Glob/Grep/Bash
  4. Skill Optimization - On-demand programming-swift loading
  5. Command Naming - Improved UX with shorter command names

Recommendations

Important (Address Before or Shortly After Merge)

1. [IMPORTANT] iOS/Swift Versions
README.md:165-171 references "iOS 26.0+" and "Swift 6.2" which don't exist yet (iOS 18/Swift 5.x are current). Clarify if these are placeholder values (update to current) or intentionally future-dated (add "or latest available").

2. [IMPORTANT] Handoff Chain Validation
Clarify code review placement in workflow:

  • README shows: Views → (optional) Review → Tests
  • But swiftui-specialist.md:145 only shows direct handoff to tests
  • Recommend updating swiftui-specialist to show both paths

3. [IMPORTANT] Dependency Audit
Add dependency evaluation criteria to swift-architect.md: maintenance status, security track record, license compatibility, Swift 6 compatibility.

4. [QUESTION] MCP Server Availability
What happens if Sosumi is unavailable? Consider graceful degradation strategy or fallback to programming-swift skill.

Suggestions (Nice to Have)

  1. Error Categorization - Add error triage guidance to swift-builder.md
  2. Test Strategy Template - Expand placeholder in swift-architect.md:140
  3. Migration Guide - Add command/agent mapping for users upgrading
  4. Context Budget - Add guidance for Opus agents to keep context under 100K tokens
  5. Troubleshooting Section - Add to README for common issues
  6. Validation Test Script - Add smoke tests to verify agent configs

Specific File Highlights

✅ Excellent Files

  • commands/feature.md - Semi-guided vs automated choice is user-friendly
  • agents/tca-architect.md - TCA Design Template shows deep expertise
  • skills/modern-swift/SKILL.md - ✅/❌ pattern comparison is incredibly clear
  • README.md - Comprehensive workflow diagram

Security, Performance, Testing

✅ Good Practices

  • No hardcoded secrets
  • Privacy manifest awareness
  • Keychain for credentials
  • Model selection optimized
  • Context management via on-demand skill loading

Test Coverage

PR includes manual test plan. Consider adding automated validation of agent configurations and handoff chains.


Final Thoughts

This refactor is a significant improvement. The agent boundary design, model optimization, and handoff model are exceptional and could serve as patterns for other agent-based systems.

The TCA architect/engineer split shows smart recognition that architectural reasoning benefits from Opus, while implementation is well-served by Sonnet.

Recommendation: Merge with confidence. The "Important" items are minor and could be addressed in follow-up PRs.

Great work! 🎉

Test Strategy Template - Expand placeholder in swift-architect.md:140

Do it

Migration Guide - Add command/agent mapping for users upgrading

Don't worry about this one.

Context Budget - Add guidance for Opus agents to keep context under 100K tokens

Yes tell them that is a target of theirs, but if its impossible not to get too hung up on it.

Troubleshooting Section - Add to README for common issues

Don't worry about that

Validation Test Script - Add smoke tests to verify agent configs

Code Review: Swift Engineering Plugin Refactor

Summary

This is a well-architected major refactor that successfully transforms the plugin into a highly specialized, modular system with clear agent boundaries and handoff patterns. The design demonstrates thoughtful separation of concerns, appropriate model optimization (Opus for planning, Sonnet for implementation, Haiku for builds), and comprehensive documentation.

Overall Assessment:Approve with minor suggestions


Strengths

1. Excellent Agent Boundary Design ⭐

The separation between planning (read-only, Opus) and implementation (write-capable, Sonnet) agents is brilliant:

  • Clear identity statements in every agent
  • Explicit handoff tables prevent confusion
  • READ-ONLY enforcement for planning agents prevents premature implementation
  • Model optimization aligns cost/performance with task complexity

2. Comprehensive Skill System 📚

The new skills are exceptionally well-designed:

  • modern-swift/SKILL.md — Excellent concurrency patterns (async/await, actors, @mainactor)
  • swift-common-patterns/SKILL.md — Production-ready patterns (DefaultProvider, ConcreteResolvable, Actor-isolated managers)
  • Modern patterns only (no deprecated APIs)
  • Clear "Use ✅ / Don't Use ❌" examples

3. TCA Architecture Split 🎯

Separating @tca-architect (design) from @tca-engineer (implementation) is a smart decision:

  • Leverages Opus for better architectural decisions
  • Reduces implementation errors by providing detailed specs
  • Clear state/action/dependency taxonomy

4. Plan File as Shared State 📋

The docs/plans/<feature>.md format serves as an effective communication mechanism:

  • Status checkboxes track progress
  • Handoff logs preserve context between agents
  • MCP server configuration documented upfront

Issues & Suggestions

[IMPORTANT] 1. Inconsistent Agent Tool Permissions

File: plugins/swift-engineering/agents/swift-architect.md:4

Issue: The agent metadata declares tools: Read, Write, Edit, Glob, Grep, Bash but the instructions explicitly state "READ-ONLY MODE" and forbid Write/Edit operations.

Problem: This creates a contradiction between the tool permissions and the behavioral instructions.

Fix: Remove Write and Edit from tools list for read-only agents (swift-architect, tca-architect, swift-ui-design)

Impact: Medium — Could lead to accidental file modifications during planning phase.


[IMPORTANT] 2. Missing Error Escalation Guidance

File: plugins/swift-engineering/agents/swift-builder.md:95

Suggestion: Add explicit escalation criteria for when to hand off vs. when to escalate to user after multiple failed attempts.


Security Review ✅

Findings: No security concerns detected

  • ✅ No hardcoded secrets or credentials
  • ✅ Appropriate logging guidance (no PII/secrets)
  • ✅ Error handling patterns include domain-specific errors
  • ✅ Concurrency patterns use modern Swift safety features
  • ✅ Dependency evaluation criteria include security checks

Performance Considerations ⚡

Findings: Well-optimized

  • ✅ Model selection optimized (Opus/Sonnet/Haiku appropriate for tasks)
  • ✅ Skills loaded on-demand (programming-swift only when needed)
  • ✅ Context budget awareness in planning agents
  • ✅ Parallel agent execution possible with clear handoffs

Code Quality & Best Practices ⭐

Excellent Patterns

  1. Consistent agent structure across all agents (Identity, Context, Responsibilities, Handoff)
  2. Self-evaluation prompts ("Have I done the best possible work?")
  3. Explicit "When to Hand Off" tables prevent circular dependencies
  4. Clear "MUST Do / MUST NOT Do" sections prevent scope creep
  5. Year context (2025) ensures modern API usage

Final Verdict

✅ APPROVED with minor fixes recommended

This refactor significantly improves the plugin's architecture and usability. The agent specialization, clear handoffs, and comprehensive skills make this a production-ready system.

Recommendation: Merge after fixing tool permissions for read-only agents.
