Tools & capabilities
PatchWarden tools 30
save_planSave an execution plan — ChatGPT writes the plan, PatchWarden stores it for local agent execution. Supports plan_ref to load a plan file already placed inside .patchwarden/plans.get_planRead a saved plan by its plan_id.health_checkCheck MCP catalog consistency, watcher freshness/supervisor state, workspace readiness, and configured agents. Use detail=self_diagnostic for expanded read-only evidence.list_agentsList configured local agents and check whether each executable currently exists. This does not start an agent or contact its model provider.create_taskCreate a repo-scoped task from exactly one source. For ChatGPT, prefer the guarded inspect_only, feature_small, or fix_tests template when it fits. A stale watcher preserves the task but returns execution_blocked and directs the client to health_check; otherwise call wait_for_task until terminal. Use execution_mode=assess_only to pre-assess risk and get an assessment_id without creating a task; then invoke the returned next_tool_call using only execution_mode=execute and the full assessment_id.get_task_statusCheck task status, execution phase, watcher health, pending reason, current command, timeout, and change evidence.get_resultRead result.md, or return structured availability and watcher evidence while the task is not terminal.get_result_jsonRead the structured result.json for deterministic task acceptance.get_diffRead task diff evidence, or return structured availability and watcher evidence while it is not ready.get_test_logRead test.log, or return structured availability and watcher evidence while it is not ready.list_workspaceList files and directories within the workspace (sensitive files excluded).read_workspace_fileRead a file within the workspace. Sensitive files (secrets, keys, tokens) are blocked. In Direct mode (with session_id), reads are scoped to the session's repo_path and return sha256.- +18 more on the listing page
