# Shaktra TDD — Testing & Coding Knowledge This skill provides the knowledge base for writing tests and production code. It is loaded by agents during the TDD pipeline — it does not orchestrate any workflow. ## Boundary **This skill defines:** HOW to write tests (practices, patterns, anti-patterns) and HOW to write production code (implementation patterns, security, observability, resilience). **shaktra-quality defines:** HOW to evaluate code and tests (checks, review dimensions, gate logic). **shaktra-reference defines:** WHAT severity levels mean (`severity-taxonomy.md`), WHAT quality principles apply (`quality-principles.md`), and WHAT the handoff state machine looks like (`schemas/handoff-schema.md`). This skill never restates severity definitions, quality dimensions, or schema structures — it references them. ## Sub-Files | File | Purpose | |---|---| | `testing-practices.md` | 12 core testing principles — behavioral testing, TDD cycle, isolation, mocking, edge cases | | `coding-practices.md` | Implementation patterns, error handling, security, observability, resilience essentials | | `resilience-practices.md` | Retry with backoff+jitter, timeouts by operation type, circuit breaker, fallback hierarchy, failure mode table | | `concurrency-practices.md` | Idempotency patterns (3 types), optimistic locking, atomic operations, concurrent test harness | | `refactoring-smells.md` | 24 code smells in 6 categories with AI-detectable patterns and transform mappings | | `re
