Implementing features or writing code. TDD is opt-in via --tdd / MEOWKIT_TDD=1. Provides code patterns, skill loading, and coding standards.From its SKILL.md

Development Toolkit

Reference guides for implementation: code patterns, TDD enforcement (opt-in), and skill lazy-loading.

When to Use

During Phase 3 (Build) for implementation guidance
When the developer agent needs coding pattern references
For TDD enforcement rules during red/green/refactor cycle (TDD mode only)

Workflow Integration

Operates in Phase 2 (Test) and Phase 3 (Build). Output supports the developer and tester agents.

TDD enforcement (tdd-enforcement.md reference) is OPT-IN as of the TDD-optional migration. Default mode skips RED-phase enforcement; enable with --tdd or MEOWKIT_TDD=1.

References

Reference	When to load	Content
code-patterns.md	During implementation	Coding patterns, architecture patterns, file organization
tdd-enforcement.md	Phase 2-3	RED/GREEN/REFACTOR cycle, test-first rules, coverage requirements

Gotchas

TDD enforcement blocking exploratory prototyping: Strict red-green cycle slows rapid iteration → Default mode (TDD off) is now the right choice for prototypes; opt into --tdd only when shipping production-quality work
200-line file rule on generated code: Auto-generated files (migrations, schemas) exceed limit by design → Exempt generated files explicitly in plan constraints
