Critical gaps across all dimensions. Tool descriptions are present but written in Chinese with minimal English context, making them inaccessible to most LLM agents. Input schemas exist but lack proper type definitions and parameter descriptions. No output schemas documented. Error handling absent. Tool names lack clear action verbs (e.g., 'delegate_to_worker' is vague about what 'delegate' means in this context). Parameters like 'worker_type' and 'repo' have no descriptions. No evidence of idempotency, pagination, or composition patterns. Security concerns: git tool accepts arbitrary shell arguments, creating injection risk.

• Translate all tool descriptions to English. Use format: '[ACTION] [WHAT] [WHEN]. Returns [STRUCTURE].' Example: 'Dispatch a task to a worker process. Call after get_active_workers() to verify the worker exists. Returns job_id and status.'
• Add parameter descriptions for every input. Example: 'worker_type (string, required): Worker identifier from get_active_workers() active list. Must match exactly.'
• Document output schemas. Example: 'delegate_to_worker returns {job_id: string, status: string, created_at: ISO8601}.'
• Sanitize git 'args' parameter. Reject pipes, semicolons, backticks, and $() syntax. Whitelist safe subcommands: worktree, diff, merge, status, log. Return clear error: 'Invalid git command: pipes not allowed.'
• Add error recovery hints. Example: 'If worker_type not found, call get_active_workers() to see available workers. If job times out, increase timeout_s parameter.'
