Sentry provides 6 tools with explicit schemas and descriptions. Naming follows verb-noun patterns appropriately (read_file, grep_search, fetch_docs, run_diagnostics, apply_patch, restart_service). All tools have descriptions and documented input schemas. However, there are significant gaps: descriptions are brief (averaging ~80 chars, below the 194-char production baseline), parameter descriptions lack detail on constraints and valid ranges, output schemas are not documented, and error handling lacks recovery guidance. The tools themselves are well-scoped (single responsibility) and composition is sound, tool chains work (e.g., read_file → apply_patch). Security considerations are present (non-root container, permission checks mentioned in Dockerfile), but not explicitly enforced in tool parameters. Overall, Sentry meets basic definition requirements but lacks the polish and depth of production-grade tools.

• Document output schemas for all tools. Specify fields, types, and examples. E.g., read_file should return {"content": string, "encoding": string, "size_bytes": integer}. grep_search should return {"matches": [{"file": string, "line": integer, "text": string}], "total_count": integer}.
• Expand parameter descriptions to include constraints and enums. For run_diagnostics, list the whitelisted commands or link to a discovery tool. For grep_search, specify regex flavor (Python re module). For fetch_docs, list approved domains and max response size.
• Add error recovery guidance to descriptions. E.g., read_file: 'If file is not found, returns error with code FILE_NOT_FOUND. Verify path is relative to project root.' apply_patch: 'If patch fails (conflict/invalid format), returns error with diff hunk line number. Inspect the file and provide corrected diff.'
• Extend descriptions to 100-200 chars following production baseline. Include WHEN to use (e.g., 'Use grep_search to find code patterns across the codebase before running diagnostics') and what makes this tool preferable to alternatives.
• Add tool annotations (readOnlyHint, destructiveHint, idempotentHint) to tool metadata. E.g., read_file and grep_search should have readOnlyHint: true. apply_patch should have destructiveHint: true (file modification). restart_service should have destructiveHint: true and idempotentHint: false (restart is not idempotent in all cases).
• For apply_patch and restart_service, document confirmation or dry-run modes. E.g., apply_patch could accept a 'dry_run' parameter to validate the patch without writing. restart_service could warn the agent of downtime and request confirmation.
