## Tools (as reported by the server, not verified)

- `list\_engines`: Lists every AAJ marketing engine: its id, the question it answers, and its category. Engines cover unit economics, pipeline forecast, budget allocation, retention, A/B significance, SEO/GEO scoring, ad spend and pricing.
- `describe\_engine`: Shows one engine's input schema: required fields, units, alternative shapes, and a worked example. Engines reject bad input rather than guessing.
- `run\_engine`: Runs an AAJ engine and returns its verdict. Give \`input\` as an object of the engine's fields. Omit \`input\` to run the engine's built-in worked example. Engines are deterministic, offline, and validate their input — a wrong unit is reported as an error, not absorbed into a confident answer.
- `search\_skills`: Finds AAJ marketing skills by the problem they solve — 'churn is rising', 'we're launching next month', 'not showing up in AI answers'. Returns matching methods and marks which have a runnable engine.
- `get\_skill`: Returns the full method for one skill: when to use it, the steps, the quality bar, and how to run its engine if it has one.
