14 tools with domain-specific governance focus. Tool names follow verb_noun pattern (build_, collect_, classify_, sign_, verify_, b1_ - b6_, tcs, sensitivity_, evaluate). Descriptions present and substantive (100 - 200 chars typical), explaining WHAT and WHEN. Input schemas visible in type annotations (Path, string, Attestation, etc.), but JSON Schema format not directly inspectable from source. Parameters have type hints and descriptions in docstrings. No critical naming conflicts. However, schema completeness cannot be fully verified without seeing actual JSON Schema registration; parameter descriptions are embedded in Python type hints rather than explicit schema descriptions. Error handling and output schemas not visible in provided code excerpt.

• Rename breakpoint tools from abbreviated form (b1_change, b2_thirdparty) to action-verb names (detect_tool_changes, check_thirdparty_exposure, detect_exfiltration_paths, evaluate_privilege_exposure, emit_audit_record, detect_capability_drift). This improves LLM discoverability and intent inference.
• Document output schemas for all tools. For each tool, provide a structured description of return fields, types, and examples. E.g., build_attestation returns {attestation: Attestation, tcs_score: float, timestamp: string}. Include pagination guidance for list-returning tools.
• Add error handling examples and recovery guidance. E.g., 'If verify_attestation fails with "invalid_signature", the attestation may be corrupted or signed by an untrusted issuer. Call verify_attestation with allow_unsigned=true to inspect the unsigned payload, or request a fresh attestation from the server operator.'
• Clarify tool composition in evaluate() docstring. Document that evaluate() internally calls b1 - b6 and returns a combined policy verdict. Explain when to call individual breakpoints (e.g., for detailed diagnostics) vs evaluate() (for a single pass/fail decision).
• Add parameter constraints to schema. For allow_unsigned (bool), document that production callers MUST set this to false. For max_tcs (float), specify valid range (0.0 - 100.0). For limit parameters, enforce min/max bounds (e.g., page_size 1 - 100). Use JSON Schema minLength, maxLength, pattern, enum, minimum, maximum.
