Two tools with basic descriptions and partial schemas. review_action has a clear purpose and documented parameters with types and descriptions, meeting baseline requirements. get_recent_decisions is simpler but adequate. However, output schemas are not explicitly documented in the code, return types are inferred from dict/list returns without formal schema declarations. No error handling guidance, no enum constraints, no pagination details for get_recent_decisions despite returning lists. Descriptions are functional (90-120 chars) but lack LLM-optimization patterns like 'when to use' or 'what happens next'. No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite both tools being read-only operations.

• Add formal output schema documentation for both tools. For review_action, document: {verdict: 'ALLOW'|'BLOCK'|'REVIEW', decided_by_stage: 1|2|3, reason: string, log_id: string}. For get_recent_decisions, document: [{verdict, decided_by_stage, reason, log_id, timestamp?}, ...].
• Enhance get_recent_decisions description: 'Returns up to [limit] most recent Sentinel review decisions from the audit log, ordered newest first. If more decisions exist, call again with a higher limit or implement cursor-based pagination.'
• Add error recovery hints: 'If review_action fails, the orchestrator may be unavailable, check logs or retry. If get_recent_decisions returns empty, the audit log may not have been initialized yet.'
• Annotate both tools with readOnlyHint: true in their schema definitions to signal to clients that these are safe, non-destructive operations.
• Clarify user_task behavior: 'Optional. If provided, Stage 3 LLM uses it to detect scope creep (e.g., agent trying to delete files when task is 'write a README'). If empty, Stage 3 skips scope validation.'
