Adds a new deterministic scoring check in src/scoring/checks/. Follows the Check[] return pattern, uses constants from src/scoring/constants.ts, and integrates in src/scoring/index.ts. Use when user says 'add scoring check', 'new check', 'modify scoring logic'. Do NOT use for display/UI changes, test modifications, or scoring display formatting.
Write Vitest tests following Caliber patterns: tests in __tests__/ directories, use vi.mock() for modules, leverage global LLM mock from src/test/setup.ts, save/restore env vars. Trigger: user says 'write tests', 'add tests', 'test this', or creates *.test.ts files. Do NOT use for non-test code or when user is debugging existing tests.
Writes Vitest tests following project patterns: __tests__/ directories, vi.mock() for module mocking with vi.hoisted() for test-time factories, global LLM mock from src/test/setup.ts, environment variable save/restore in beforeEach/afterEach, vi.clearAllMocks() lifecycle, and test file organization. Use when user says 'write tests', 'add test coverage', 'test this', creates *.test.ts files, or when test failures appear in CI. Do NOT use for non-test code or for debugging without writing tests.

Use when user says 'write tests', 'add tests', 'test this', or creates *.test.ts files. Do NOT use for non-test code or documentation.
Create a new CLI command following Commander.js pattern. Handles command file in src/commands/, registration in src/cli.ts, telemetry tracking via tracked() wrapper, and option parsing. Use when user says 'add command', 'new CLI command', 'create subcommand', or adds files to src/commands/. Do NOT use for modifying existing commands or refactoring command structure.
Creates a new CLI command following the Commander.js pattern in src/commands/. Handles command registration in src/cli.ts, telemetry tracking via tracked() wrapper, and option parsing. Use when user says 'add command', 'new CLI command', 'create subcommand', or asks to add files to src/commands/. Do NOT use for modifying existing commands or refactoring command logic.
Creates a new CLI command following the Commander.js pattern in src/commands/. Handles command registration in src/cli.ts, telemetry tracking via tracked() wrapper, and option parsing. Use when user says add command, new CLI command, create subcommand, or adds files to src/commands/. Do NOT use for modifying existing commands or fixing bugs in existing commands.
Adds a new platform writer in src/writers/ following existing patterns (claude, cursor, codex). Returns string[] of generated file paths. Integrates with writeSetup() orchestration. Use when implementing 'add platform', 'new writer', 'support new agent'. Do NOT use for refactoring existing writers or modifying writers/index.ts exports.
Adds a new platform writer in src/writers/ following existing patterns (claude, cursor, codex). Generates platform-specific CLAUDE.md, .cursor/rules/, or AGENTS.md configs and integrates with writeSetup(). Use when adding support for a new agent platform or AI tool. Trigger phrases: 'add platform', 'new writer', 'support new agent', 'integrate with X'. Do NOT use for modifying existing writers or one-off file generation.
Captures and analyzes performance traces to identify slow queries and N+1 problems. Use when analyzing performance or optimizing database queries.
Manages database migrations and model changes. Use when creating migrations, running migrations, or modifying models.
Provides Tailwind CSS patterns for Plain templates. Use when styling templates or working with conditional CSS classes.
Installs Plain packages and guides through setup steps. Use when adding new packages to a project.
Upgrades Plain packages and applies required migration changes. Use when updating to newer package versions.
Runs Python with Plain configured and database access. Use for scripts, one-off commands, or interactive sessions.
Retrieves detailed documentation for Plain packages. Use when looking up package APIs or feature details.
Runs pre-commit checks before finalizing changes. Use this when you've finished making code changes to verify everything passes before committing.
