Every session.

Code review orchestrator. Detects the language of changed files and routes to the appropriate specialist reviewer (typescript-reviewer, go-reviewer, python-reviewer, java-reviewer, swift-reviewer, ruby-reviewer, elixir-reviewer, rust-reviewer, cpp-reviewer). Falls back to universal security and quality checks when no specialist exists. Use immediately after writing or modifying code.

Test-Driven Development specialist enforcing write-tests-first methodology. Use PROACTIVELY when writing new features, fixing bugs, or refactoring code. Ensures 80%+ test coverage (configurable — check project's `.nycrc`, `vitest.config.ts`, or `pytest.ini` for the project's actual threshold).

Task decomposition and implementation planning specialist. Use PROACTIVELY when users need WHAT tasks to execute — produces PRDs, task breakdowns, timelines, and dependency maps. For HOW to structure the system (component design, ADRs, C4 diagrams), use the architect agent instead.

Security vulnerability detection and remediation specialist. Use PROACTIVELY after writing code that handles user input, authentication, API endpoints, or sensitive data. Flags secrets, SSRF, injection, unsafe crypto, and OWASP Top 10 vulnerabilities.

System design and architecture specialist. Use PROACTIVELY when users need HOW to structure the system — component boundaries, ADRs, C4/arc42 diagrams, scalability decisions. For task lists and implementation timelines (WHAT to build), use the planner agent instead.

Build error resolution specialist for any language — TypeScript, Go, Python, Java, and more. Use PROACTIVELY when builds fail, type errors occur, or compilation breaks. Fixes errors only with minimal diffs, no architectural edits. Focuses on getting the build green quickly.
