Initialize a new project workflow graph with task nodes, phase milestones, dependencies, and validation commands.

Retrieve current workflow graph state, including visual ASCII progress table, Mermaid diagram, phase progress, nodes, error logs, and execution timeline.

Get phase progress summary, completion percentages, phase gate statuses (BLOCKED, IN_PROGRESS, COMPLETED), and blocking reasons.

Get all task nodes whose dependencies and phase gates are satisfied and are ready to be worked on.

Mark a task node as IN_PROGRESS to start working on it. Enforces phase gates before allowing execution.

Execute the validation command for a task node with duration tracking and attempt error logging. Streams live output via progress notifications when supported.

Run validation commands for multiple READY/IN_PROGRESS tasks concurrently with atomic sequential state accumulation (race-condition free).

Add a new task node dynamically into the active workflow graph with optional phase and category. Validates dependency references and checks for cycles before inserting.

Update an existing task node properties, phase, status, or validation command. Re-validates dependency references and cycle-checks after update.

Reset a task node status to PENDING and clear its error logs, allowing a fresh retry from the beginning.

Reset all FAILED (and optionally IN_PROGRESS) nodes in a phase back to PENDING, skipping COMPLETED nodes.

Get chronological execution timeline for a node, including timestamped attempts, exit codes, error logs, and duration in milliseconds.

Persist the current workflow state to disk using atomic write (write-to-temp then rename) to prevent corruption.

Load a workflow graph state from a JSON file on disk with full Zod schema validation.

Switch the active project context to a different project that was previously initialized with init_project_graph. Lists available projects if the requested one is not found.

Generate standard project documentation files (Architecture/ER Diagram, Phase-wise Tasks, and Test Cases) in the project workspace based on provided project requirements. Useful for initializing a project plan before creating the graph.
