Dead code cleanup and consolidation specialist for Go, Python, and JS/TS. Use PROACTIVELY when unused code, duplication, or a large mechanical refactor is suspected. Detects with stack-native tools, proves semantic equivalence, removes in reviewable batches.

Strict Go code reviewer that enforces evidence-based principles and project-specific rules from CLAUDE.md/AGENTS.md/LEARNINGS.md. Use for any Go change. Reports only findings backed by a cited rule and a concrete fix — never taste calls.

Performance analysis and optimization specialist for Go, Python, and Node services. Use PROACTIVELY when a hot path, latency budget, memory growth, or perf regression is raised. Profiles first, benchmarks before/after, wires regression budgets into CI.

Strict Python code reviewer that enforces evidence-based principles and project-specific rules from CLAUDE.md/AGENTS.md/LEARNINGS.md. Use for any Python change. Reports only findings backed by a cited rule and a concrete fix — never taste calls.

Proportional proof guide for new features, bug fixes, and refactors. Selects Surgical, Targeted, or Full verification before editing; uses RED → GREEN → REFACTOR only when the selected profile calls for behavior or regression coverage. Stack-aware: speaks scoped Make, Go, Python, and Node proof commands.

TypeScript/Node conventions — strict compiler settings, parse-don't-cast boundaries, Result-style domain errors, floating-promise hygiene, ESM. Use when writing or reviewing TypeScript.

FastAPI service-layer architecture, dependency injection, domain-error handling, SQLAlchemy 2.0 async, and Alembic conventions. Use when building or modifying FastAPI apps, in addition to python-patterns.

Use when choosing a branching strategy, hunting a regression with git bisect, running multi-worktree development, or configuring CODEOWNERS and merge queues — falsifiable conventions, not a git tutorial.

Use when designing or reviewing an HTTP/RPC API surface — resource modeling, pagination, error envelopes, versioning, idempotency. Falsifiable contracts, not style preferences.

Use for GitHub repo operations via the gh CLI — issue triage, PR and CI management, releases, Dependabot — plus CODEOWNERS, reusable workflows, and monorepo path filtering. For operational tasks beyond plain git.
