Telaios provides 6 tools with clear action-verb naming (search_*, read_*, write_*, run_*, finish). All tools have descriptions (avg ~120 chars, within baseline 34-392 range). Input schemas are present with typed parameters. However, parameter descriptions are minimal or absent in several tools (search_repository's 'collection' param lacks detail; run_shell has no guidance on command format/safety). Output schemas are not documented. Error handling is implicit rather than explicit, no recovery guidance or categorization. Tool composition is reasonable but finish() is a meta-tool that doesn't fit standard patterns. Security concerns: run_shell is DESTRUCTIVE with no rate limiting, confirmation, or audit trail visible in the code.

• Document output schemas for all tools. For search_documents and search_repository, specify: { results: [{ snippet: string, source: string, score: number }], total: number }. For read_file: { content: string, path: string, size: number }.
• Add explicit error handling to run_shell: categorize errors as retryable (timeout, transient failure) vs fatal (command not found, permission denied). Return actionable messages: 'Command timed out after 30s. Try a simpler command or increase timeout.'
• Enhance search_repository description: list available collections or explain how to discover them. Add: 'If collection is omitted, searches the main repositories collection. Available collections: [list or discovery method].'
• Add command validation to run_shell. Reject or warn on dangerous patterns (rm -rf, dd, >, |). Document allowed command families in the description.
• Replace finish() with protocol-level completion. Use MCP's result field with a structured completion message instead of a callable tool. This aligns with MCP semantics and prevents agents from calling finish() mid-task.
