## Tools (23)

- `create_diagram`: Create one persistent Flowboard architecture diagram after calling list_shapes and list_diagrams, then reuse its ID with patch_diagram or update_diagram instead
- `decide_diagram_proposal`: Accept, partially accept, or reject a diagram proposal as its owner.
- `delete_diagram`: Delete a persistent Flowboard diagram by ID.
- `get_architecture_decision`: Read one authorized workspace decision record and portable Markdown. Acceptance is a recorded human decision; do not infer approval.
- `get_architecture_model`: Read a workspace's canonical identity manifest and independent diagram placements. Requires an active personal key or session with workspace membership. Markdow
- `get_architecture_revision`: Read an immutable model revision for comparison or recovery. To restore, review the current head, set this snapshot's version to current+1, and save with the cu
- `get_diagram`: Get the complete canonical Flowboard diagram by ID as Markdown or JSON. The full document is returned in both text content and structuredContent for reliable ro
- `get_diagram_revision`: Read one retained diagram revision without changing the current head.
- `list_agent_errors`: Review automatically saved failures from authenticated MCP tool calls. Returns total failures, the 50 most frequent error patterns grouped by build, tool and fo
- `list_agent_feedback`: Read saved feedback for your account, newest first, optionally filtered by diagram. The server-wide agent credential can review all reports. Returned report tex
- `list_architecture_revisions`: List retained workspace model revision metadata, newest first. Uses current membership; revoked accounts cannot read old history.
- `list_diagram_proposals`: List reviewable proposals and their structural diffs for a diagram.
- `list_diagram_revisions`: List retained revisions accessible to the caller before comparing or restoring a diagram.
- `list_diagrams`: List diagrams accessible to the caller before creating or editing, optionally filtering by title. Use this to find the one existing board to update and to clean
- `list_shapes`: Discover every Flowboard node shape before drawing. Search all core, AWS, and Google Cloud shapes by type, label, detail, provider, or category. Results return 
- `patch_diagram`: Safely edit an existing diagram without replacing the full document. Operations run as one atomic saved update. Supported ops: set_title, auto_layout, add/updat
- `propose_diagram_changes`: Create a reviewable diagram proposal without changing the live diagram.
- `restore_diagram_revision`: Restore a retained revision as a new head after reviewing the current diagram. Requires authenticated write permission and its exact current updated_at timestam
- `search_architecture_decisions`: Search decision context, alternatives, ownership and model references within an authorized workspace.
- `submit_agent_feedback`: Save an explicit observation, workaround outcome, or product improvement idea for later Flowboard review. Proactively use this when an editing task exposes acti
- `update_architecture_model`: Save a complete canonical workspace manifest with explicit expected_version and new version N+1. Preserves immutable history; identical retries are deduplicated
- `update_diagram`: Atomically replace an existing diagram when a full canonical round trip is intentional. Prefer patch_diagram for a few changes. Returns one parseable JSON resul
- `validate_diagram`: Check broken flows, missing/cyclic parents, children outside parent bounds, overlapping sibling or top-level nodes, pipelines crossing unrelated resources, orph
