14 tools with complete input schemas and descriptions, but quality is uneven. Most descriptions are terse (10-50 chars), below the 50-200 char baseline for LLM optimization. Parameter descriptions are minimal or absent in many cases. No output schemas documented. Error handling and recovery guidance missing. Tools like send_mail, claim_path, and work_acquire lack sufficient context for LLM selection. Naming is verb-first and clear, but descriptions do not explain WHEN to use each tool or what it returns.

• Expand all descriptions to 50-200 characters. Include WHAT the tool does, WHEN to use it, and WHAT it returns. E.g., 'Claim exclusive access to a file or directory to prevent concurrent modifications. Use before reading/writing shared files. Returns a claim ID; release with release_claim() when done.'
• Document output schemas for all tools. Specify field names, types, and what data is returned. E.g., list_sessions should return [{sessionId, name, status, capabilities}].
• Add parameter descriptions that explain format, constraints, and how to obtain values. E.g., 'to: Session name (from list_sessions), session ID, or "all" for broadcast. Returns error if session not found.'
• Add error handling guidance to descriptions. E.g., 'claim_path: Returns error if path already claimed by another session. Call list_claims() to see active claims and release_claim() to free a path.'
• Distinguish coordination tools with clearer names and descriptions. Consider renaming work_* to lease_* or adding a 'coordination_type' parameter to unify the interface.
