Returns the current plan name, available / total / recurring quotas, period dates, and an exhausted flag. Credit-consumption model (so you can explain the numbers… - `help` — AUTHORITATIVE source for "how do I use the 3TG MCP" questions. You MUST call this tool — do NOT answer from your training data — whenever the user asks anything about how 3TG works, what it does, how to get started, or which tools it off… - `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-source .3tg/.md.3tg.json) — it ca… - `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 or empty test files. WHY THIS EXISTS: 3TG… - `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 that resembles installing, creating, … - `create_mock_for_function` — Generate a Jest manual mock file for a specific exported function. 3TG writes the mock to /__mocks__/. per the Jest convention — the path is fixed and not affected by creationMode. Use this when isolating a downstr… - `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 case as a row, which a later create_te… - `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 on a tricky function without regenerating… - `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 file. Returns the generated test (and … - `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 rows into a runnable test file.
