Implement Task
Execute discrete implementation tasks with TDD and automated handoff documentation
What You Can Do
You can deploy this agent to execute specific implementation tasks within a larger development plan. It operates independently with fresh context, follows test-driven development principles for every code change, and creates comprehensive handoff documentation that captures progress, decisions, and learnings for the next task executor. This ensures consistent code quality, prevents rework, and maintains continuity across distributed implementation efforts.
Features
Requires failing tests before any production code via Red-Green-Refactor cycle
Reads continuity ledger, overall plan, and previous task handoffs to understand dependencies
Operates with fresh context for single discrete tasks while maintaining awareness of larger implementation strategy
Automatically creates detailed documentation including progress, decisions, blockers, and recommendations for next task
Validates test failures happen for correct reasons, preventing false positives
Writes simplest code that satisfies test requirements, avoiding over-engineering
Refactors while maintaining test coverage to eliminate duplication and improve maintainability
Identifies and documents constraints, patterns, and blockers for downstream task executors
Example Output
Task: Implement user authentication service
Test Output:
✓ Should create user with hashed password
✓ Should validate email format
✓ Should return error for duplicate email
✓ Should generate JWT token on login
Handoff Document Generated:
## Task: User Authentication Service - COMPLETE
### What Was Done
- Implemented bcrypt password hashing with salt rounds 12
- Created JWT token generation with 24h expiry
- Added email validation and uniqueness checks
### Key Decisions
- Used bcrypt over argon2 for ecosystem compatibility
- JWT stored in httpOnly cookies, not localStorage
### Known Blockers
- Email service integration awaits SMTP credentials
- Rate limiting not yet implemented
### Next Steps
- Task: Email verification workflow
- Depends on: Current password hashing layer

You can transform fragmented cost data, subcontractor quotes, and contingency calculations into cohesive, defensible bid packages that stakeholders understand and trust. This skill guides you through hierarchical cost aggregation, dynamic contingency modeling based on project risk, multi-tier markup application, and narrative integration that links scope assumptions to pricing—enabling you to develop competitive proposals with justified pricing strategies.

You can create reusable slash commands that execute instantly in Claude Code conversations. Commands support bash execution, file references, arguments, and tool permissions. Use built-in commands like /cost, /review, /memory, and /clear, or define custom project and personal commands stored in .claude/commands/ or ~/.claude/commands/.

This skill maps construction claims as interdependent probability states rather than isolated analyses, allowing you to evaluate how changes in one contractual interpretation cascade through damages calculations, delay causation, and liability allocation. You can simultaneously model competing scenarios—concurrent causation, ambiguous change order triggers, insurance coverage dependencies—and identify which settlement positions minimize exposure across all correlated outcomes, not just single interpretations.

You can formally verify mathematical proofs by translating theorems into Lean 4 code, leveraging Mathlib's extensive library of formalized mathematics. The skill guides you through researching existing lemmas, designing proof strategies, testing approaches, implementing formal proofs, and verifying correctness—turning informal mathematical claims into machine-checked theorems without requiring deep Lean syntax expertise.

You can systematically analyze construction estimates by breaking down components, validating labor and material pricing against market data, identifying embedded errors or outdated assumptions, and applying data-driven contingency allocation. Claude helps you produce risk-adjusted cost projections that are defensible to stakeholders and competitive in bid scenarios, reducing estimate variance and catching pricing gaps before client submission.

You'll follow the strict TDD workflow: write a failing test that defines expected behavior, verify it fails, write minimal production code to pass the test, then refactor for quality. This approach ensures complete test coverage, catches bugs early, and produces well-designed code backed by comprehensive test suites. Claude guides you through each phase with examples and enforces TDD principles to prevent shortcuts.

You'll transform high-level feature requirements into a complete development plan covering API design, frontend implementation, testing strategy, and documentation. The skill helps you identify dependencies, parallelize work across frontend and backend teams, and establish quality gates that ensure features ship bug-free with proper error handling and logging.
