GemCode exposes 13 tools with mixed quality. Naming is generally verb-first and clear (semantic_search_files, synthesize_tool, org_delegate). Descriptions are present and substantive (avg ~150 chars), explaining WHAT and WHEN. However, input schemas are incomplete: many parameters lack type definitions or descriptions. For example, synthesize_tool's 'script_content' has no length limits or format guidance. Output schemas are entirely undocumented, callers cannot predict response structure. Error handling is minimal; no recovery guidance or actionable error messages visible. Tool composition is reasonable (single responsibility mostly observed), but parameter relationships (e.g., trigger_kind determining which of at_hhmm/every_seconds/cron apply) are documented only in descriptions, not enforced. Security concerns: org_delegate and org_spawn accept arbitrary task strings with no sanitization visible; synthesize_tool accepts bash/python scripts with no validation. No audit logging, permission gates, or scope declarations evident.

• Document output schema for every tool. Example for semantic_search_files: {"query": string, "matches": [{"path": string, "score": float, "snippet": string}], "backend": string}. Use JSON Schema format.
• Add input validation and sanitization to synthesize_tool and run_synthesized_tool. Reject scripts containing dangerous patterns (e.g., 'rm -rf', 'sudo', '$(...)'); document allowed script patterns.
• Wrap org_delegate and org_spawn task strings through a sanitizer (similar to query_sanitizer in semantic_search_files). Reject or escape shell metacharacters and prompt injection patterns.
• Add regex patterns or enums to parameter descriptions. For synthesize_tool name: 'Lowercase alphanumeric and dashes only, 1-50 chars (regex: ^[a-z0-9-]+$)'. For automations_init cron: 'Valid cron expression (5 fields: minute hour day month weekday)'.
• Implement error classification and recovery guidance. Return {"error": "...", "code": "not_found|invalid_input|permission_denied|timeout", "recovery": "Try search_users() first"} instead of bare error strings.
