Implements a multi-agent security review pipeline: shard planning, parallel scanning agents, false-positive triage with persisted state, and SARIF output. Reusable as a reference for any security-audit automation that needs to split work across sub-agents and track findings deterministically.

Catalog of 8 concrete test optimization patterns (DB transactions, mocks, parallelization) with before/after code. Self-contained and adaptable to any language/test framework; demonstrates non-obvious testing techniques rather than framework boilerplate.

Provides a structured method for analyzing state transitions in a codebase, useful for debugging and impact analysis. The pattern is tool-agnostic and can be extracted into a standalone static-analysis checklist.

Core AITDD implementation skill that enforces a disciplined Red-Green-Refactor-Validation loop with confidence signals. The workflow rules are written as agent instructions and can be reused as a template for AI-driven TDD processes in other agent frameworks.
