22 tools with mixed quality. Naming is generally strong (verb_noun pattern, clear intent). Descriptions present but often generic or incomplete, many lack context on WHEN to use the tool or what it returns. Schemas visible for most tools but parameter descriptions are sparse or missing. Critical gaps: no output schemas documented, no error handling guidance, no security/permission declarations. Composition is reasonable (tools are single-purpose) but many lack chaining metadata (e.g., delegate_task returns what IDs? How does delegate_handoff consume them?). Backward-compatible aliases (agy_run_task, agy_chat, agy_plan) add cognitive load without clear value.

• Document output schemas for all 22 tools. Example: delegate_task should return {session_id: string, diff: string, files_modified: string[], status: 'success'|'timeout'|'error', error_message?: string}. This enables chaining.
• Remove backward-compatible aliases (agy_run_task, agy_chat, agy_plan). Keep only primary tools (agy_task, agy_ask). Reduces cognitive load and clarifies intent.
• Expand parameter descriptions with context. E.g., 'thinking: Effort level for reasoning. Use "low" for simple tasks, "high" for complex logic, "max" for critical decisions.' Add constraints: 'mode: edit (modifies files), plan (architectural only), explain (read-only analysis)'.
• Add error handling guidance to WRITE tools. E.g., delegate_task: 'If timeout occurs, check agent logs via agents_status. If permission denied, ensure dangerouslySkipPermissions=true or grant workspace write access.'
• Declare security scopes for each tool. E.g., delegate_task: 'Requires: write:workspace, read:git. Audit: all file modifications logged to session.' Add permission gates in implementation.
