Tools
| Tool | Description | Behaviour |
|---|---|---|
| ecca_bts_divergence | Measures lexical and semantic divergence across candidate assertions to penalize sycophancy. | Read-only |
| ecca_claim_protocol_validate | Check one ecca.claim-protocol 1.0 document for shape: versioned, engine slots only (no vendor names), split causes from the published taxonomy, question text only with consent, seal present. Returns ok with the error list; validates shape, never the record behind it. | Read-only |
| ecca_decision_tournament | Evaluates multi-option decision matrix using minimax regret and Pareto ranking over candidate pathways. | Read-only |
| ecca_learning | Learning and study skills: refine the question, fetch studies, and show named claims before the verdict. Applies evidence and claims checks; spends one solve. | Changes data |
| ecca_money | Money and business: refine the question, fetch studies, and show named claims before the verdict. Applies evidence and claims checks; spends one solve. | Changes data |
| ecca_nutrition | Nutrition and supplements: refine the question, fetch studies, and show named claims before the verdict. Applies evidence and claims checks; spends one solve. | Changes data |
| ecca_pre_mortem | Executes an adversarial pre-mortem identifying failure modes and early warning indicators using empirical argument verification. | Read-only |
| ecca_psychology | Psychology research: refine the question, fetch studies, and show named claims before the verdict. Applies evidence and claims checks; spends one solve. | Changes data |
| ecca_refine | Use one keyed tier-quota slot to sharpen rough student questions without adding facts; return detected niches and refinement chips. A closed engine ceiling falls back locally. | Read-only |
| ecca_research | Use one keyed tier-quota slot and dispatch-ceiling reservation to fetch and grade studies from scholarly indexes; return fetched evidence and explicit gaps. | Read-only |
| ecca_synthesize | Compare answers from configured engines and inspect disagreement, with lexical similarity and final-answer agreement when measurable. | Changes data |
| ecca_verify | Independently answer a question and compare the candidate against deterministic panel agreement. Show named dissent; spends one solve. | Changes data |
