8 tools with explicit schemas and descriptions, but significant quality gaps. Tool names follow verb_noun convention (list_, create_, send_, etc.), which is good. However, descriptions are inconsistent: some are detailed (send_keys, run_shell_command), others are vague or repetitive ('Inspect tmux metadata' appears twice). Parameter descriptions exist but lack actionable constraints, e.g., 'Target pane identifier' without explaining the %[0-9]+ format requirement. No output schemas documented. Error handling is minimal; no recovery guidance. Security concerns: send_keys and run_shell_command accept arbitrary shell input with no sanitization warnings. Composition is reasonable (8 focused tools), but no pagination, no batch operations, and no idempotency guarantees stated.

• Document output schemas for all 8 tools. Example: list_sessions should return {sessions: [{id: string, name: string, window_count: number}], total: number}. This enables LLMs to chain calls and extract IDs for downstream operations.
• Enhance parameter descriptions with format constraints. Change 'Target pane identifier' to 'Target pane identifier (format: %[0-9]+, e.g., %0, %1)' so LLMs understand valid input without guessing.
• Add confirmation or dry-run support for destructive tools. send_keys and run_shell_command should document that they execute immediately with no undo. Consider a dry_run parameter or a separate preview_command tool.
• Distinguish list_sessions from get_session_info in descriptions. E.g., 'List all sessions with basic metadata' vs 'Get detailed info for a specific session (windows, panes, status)'. This prevents LLM confusion.
• Add error handling guidance. Document that 'session not found' is user-fixable (call list_sessions to find valid IDs), while 'tmux socket error' is retryable. Include recovery suggestions in error responses.
