SIOF has 8 tools with basic schemas and descriptions, but significant quality gaps prevent production use. All tools have descriptions (10-80 chars, mostly under the 194-char baseline), and input schemas are present with type definitions. However, descriptions are generic and lack LLM-optimized guidance on WHEN to use each tool or WHAT happens next. Parameter descriptions are minimal (e.g., 'Scope to analyze' for get_dead_paths lacks format/range guidance). No output schemas are documented, LLMs cannot plan downstream calls. Error handling is absent: no recovery guidance, no categorization of retryable vs fatal errors. The apply_patch_to_file tool is destructive but has no confirmation pattern, dry-run option, or audit trail documentation. Tool composition is weak: find_data_lineage and impact_of_change overlap semantically but lack clear disambiguation. No pagination support visible despite tools returning potentially large result sets (dead_paths, unhandled_exceptions). Security: no evidence of permission gates, audit logging, or secret injection patterns despite enterprise claims.

• Document output schemas for all 8 tools. Specify field names, types, and whether results are paginated. Example: 'Returns {lineage: [{node_id: string, depth: int, relation: string}], total_count: int, next_cursor?: string}'.
• Add confirmation/dry-run pattern to apply_patch_to_file. Require a separate confirm_patch(patch_id) call or add a 'dry_run: boolean' parameter. Document rollback guidance.
• Enhance parameter descriptions with format, range, and valid values. Replace 'Scope to analyze' with 'Scope to analyze (e.g., "src/", "tests/", or "*" for entire codebase; defaults to "*")'.
• Add error handling guidance to all tools. Document: (1) what errors are retryable (e.g., timeout), (2) what user action is needed (e.g., 'symbol not found, try search_symbols()'), (3) fatal errors with no recovery path.
• Clarify find_data_lineage vs impact_of_change in descriptions. E.g., 'find_data_lineage: trace how data flows INTO a symbol. impact_of_change: trace what breaks if a symbol changes.' Add examples.
