Two tools with minimal documentation. Both have descriptions (good), but input schemas lack parameter-level descriptions entirely. trustline.simulate accepts 'policy' and 'transcript' objects with only type and high-level descriptions; trustline.verify accepts 'audit' with minimal context. No output schemas documented. Parameter descriptions do not explain format, constraints, or expected structure. Naming is domain-specific but not action-verb-based (simulate/verify are verbs, but lack clarity on what data structures they operate on). No error handling guidance, no examples of valid inputs, no recovery paths.

• Add parameter-level descriptions to both tools. For trustline.simulate: describe what a valid 'policy' object looks like (reference the trustline.policy/v1 schema), explain the 'transcript' array format (JSON-RPC request strings), and state the expected output (audit trail with hash chain). For trustline.verify: describe the 'audit' bundle structure and what validation checks are performed.
• Document output schemas explicitly. State what fields trustline.simulate returns (e.g., audit_trail, hash_chain, policy_digest, tamper_evidence) and their types. Same for trustline.verify (e.g., valid: boolean, errors: array, hash_chain_valid: boolean).
• Expand tool descriptions to 100 - 200 characters. Include: (1) What the tool does, (2) When to call it (e.g., 'Call after generating a transcript to produce a tamper-evident audit'), (3) Prerequisites (e.g., 'Requires a valid trustline.policy/v1 object'), (4) Key output (e.g., 'Returns a deterministic audit trail with SHA-256 hash chain').
• Add error handling guidance. Document common failure modes: invalid policy schema, malformed transcript, hash chain mismatch. For each, provide a recovery hint (e.g., 'If policy validation fails, check that the policy conforms to trustline.policy/v1 schema').
• Rename tools to follow verb_noun_object convention: 'simulate_trustline_policy' and 'verify_audit_bundle' to make the subject and action explicit, improving LLM tool selection clarity.
