|---|---|---|
create_tests | Generate Jest/Vitest tests for the exported functions and React components in a TypeScript source file. Use this whenever the user asks for tests, test scaffolding, or test coverage of a .ts or .tsx f | typed |
create_spec | Generate a functional-requirements spec (`.3tg.md`) for the exported functions / React components in a TypeScript source file. This is "Flow A" — the human-editable Markdown table that lists each test | typed |
create_tests_from_spec | Compile a hand-edited functional-requirements spec (`.3tg.md`) into actual Jest/Vitest tests. This is "Flow B" — the user has already authored or reviewed the `.3tg.md` and is ready to materialise the | typed |
create_spec_for_function | Generate a functional-requirements spec (`.3tg.md`) scoped to a single exported function or React component. Same shape as `create_spec` but restricts the output to one symbol — useful when iterating | typed |
create_mock_for_function | Generate a Jest manual mock file for a specific exported function. 3TG writes the mock to `<srcDir>/__mocks__/<basename>.<ext>` per the Jest convention — the path is fixed and not affected by `creatio | typed |
validate_spec | Lint a `.3tg.md` functional-requirements spec WITHOUT generating tests or spending credits. Run this before `create_tests_from_spec` to catch the mistakes that would otherwise silently produce broken | typed |
validate_config | Validate a 3TG configuration object (`.3tg.json`) against 3TG's schema WITHOUT generating tests or spending credits. Use this whenever you or the user has hand-edited `.3tg/config.3tg.json` (or a per- | typed |
get_client_info | Look up account info for a 3tg.dev clientId WITHOUT consuming any credits. Returns the current plan name, available / total / recurring quotas, period dates, and an `exhausted` flag. Credit-consumpti | typed |
create_agent_instructions | AUTHORITATIVE source for "install / create / set up 3TG agent instructions" requests. You MUST call this tool — do NOT write the instructions from your training data — whenever the user asks anything | typed |
