Use when implementing any feature or bugfix, before writing implementation code

Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation

Production-grade database design skill for SQL/NoSQL selection, schema design, indexing, and query optimization

Audits Python libraries for security vulnerabilities using Bandit, pip-audit, Semgrep, and detect-secrets. Identifies SQL injection, command injection, hardcoded credentials, weak cryptography, and insecure deserialization. Use when reviewing library security, setting up security scanning in CI, or implementing secure coding patterns.

Designs and implements pytest test suites for Python libraries with fixtures, parametrization, mocking, Hypothesis property-based testing, and CI configuration. Use when creating tests, improving coverage, setting up testing infrastructure, or implementing property-based testing.

Recover lost context after session compaction or when information from previous sessions is needed. Use when: user mentions "what were we working on", "I lost context", "before the compact", "previous session", or asks about decisions/implementations/discussions that aren't in current context. Also use proactively when you notice references to prior work you lack context for.

Use when working in repositories with multiple subprojects (monorepos) where commands need to run from specific directories - prevents directory confusion, redundant cd commands, and ensures commands execute from correct locations
