Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].
dry_run_workflowPreview what a workflow would do without executing any task. Give a `workflow` (a name from list_workflows or a file path) and optional `params`; returns `{status, outputs, preview}` where `preview` is a human-readable list of the steps that would run with their resolved inputs (the same information as the CLI's --dry-run). Use this to inspect side effects (shell commands, file writes, HTTP calls) before running for real. It does not execute any task — no shell or Python runs and none of the workflow's own side effects occur; only ephemeral logs are written to a temporary workspace.
list_workflowsList the workflows available in this server's workflow directory. Returns an object with `count` and `workflows` (one entry per workflow, each containing `name` (its declared name), `description`, `path` (the YAML file), and `parameters` (declared inputs with types and defaults)). Call this first to discover which workflows exist and what inputs each accepts before calling dry_run_workflow or run_workflow. Read-only: it only reads YAML files and never executes anything. Takes no arguments.
run_workflowExecute a workflow and return its results. Give a `workflow` (a name from list_workflows or a file path) and optional `params`; runs it to completion and returns `{status, workflow, outputs}` where `outputs` maps each step name to its result. DESTRUCTIVE: a workflow may run arbitrary shell commands and Python, write files, and make HTTP requests — call dry_run_workflow first if you need to preview side effects, and only run workflows you trust.
validate_workflowValidate a single workflow YAML file without running it. Give the file `path`; returns `{valid, error_count, warning_count, issues[]}`, where each issue has a level (error/warning/info), message, and optional line, step, and hint. Use this to check a workflow the agent authored or edited before running it, or to explain why a workflow is malformed. Read-only: no tasks run and nothing is written.
