Measured tools (5)

• list_engines read-only

  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.

  Parameters:

  • category — string — Optional filter. Words are matched against the engine's category, id and skill title (for example "pricing", "retention" or "seo audit"), then against its summary.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• describe_engine read-only

  Shows one engine's input schema: required fields, units, alternative shapes, and a worked example. Engines reject bad input rather than guessing.

  Parameters:

  • engine (required) — string — Engine id.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• run_engine read-only

  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.

  Parameters:

  • engine (required) — string — Engine id.
  • input — ['object', 'string'] — The engine's configuration object. Some engines also accept a named mode as a plain string (for example 'design' or 'readout'). Omit for the demo.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• search_skills read-only

  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.

  Parameters:

  • query (required) — string — The problem, in plain words.
  • limit — integer — Max results, default 8.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_skill read-only

  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.

  Parameters:

  • skill (required) — string — Skill slug.

  Hints: read-only yes · destructive no · idempotent yes · open-world no
