Need help deploying YAML Workflow?
Chalk Labs sets up agents like this inside real teams: connected to your tools, tested on your data, with a human in the loop where it matters.
Install
Works with Claude Code, Codex, VS Code, Cursor, Windsurf, Claude Desktop. Read the repository before you give any tool access to your data.
npx agentmarket install connector/orieg-yaml-workflow
Asks which of your tools to add it to (Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI, Claude Desktop) and shows the change first. See https://agentmart.dev/cli.

Tools (4)
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.
