fastworkflow: Skill for Claude Code

.claude/skills/fastworkflow-run-and-operate/SKILL.md

fastworkflow-run-and-operate is a skill for Claude Code from radiantlogicinc/fastworkflow. It costs 208 tokens per session (6,986 once invoked), scanned B, original, Apache-2.0.

A runbook for operating fastWorkflow, a framework for running command-based AI workflows. It covers the command-line tool, bundled examples, runtime modes, servers, and generated runtime files.

In plain words
What is it for?
Use it to fetch examples, train and run workflows, choose agent or assistant mode, launch the HTTP/MCP server, interpret status codes, and identify removable runtime folders.
Why use it?
It helps you run workflows correctly and understand the files they create. This reduces errors when choosing a mode, starting a server, or cleaning temporary artifacts.

    Tool defaults are unsafe or overly permissive (e.g. disabled TLS verification, no authentication, world-writable permissions). Unsafe defaults widen the attack surface.
    Fix: Override unsafe defaults with secure settings (verify=True, auth required, restrictive permissions). Review and harden all tool configurations.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

fastworkflow-run-and-operate scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

fastWorkflow: Run and Operate

Runbook for operating fastWorkflow v2.22.2: the fastworkflow CLI, the bundled examples, the runtime artifacts on disk, and the FastAPI+MCP server. Every command, flag, path, and endpoint below was verified against the code on 2026-07-09 (see Provenance at the end).

When to use / when NOT to use

Use this skill when you are running things: fetching examples, training-then-running a workflow, choosing agent vs assistant mode, launching the HTTP/MCP server, interpreting its status codes, or deciding which ___* directory is safe to delete.

Use a sibling instead when:

Jargon used below, defined once:

  • Workflow — a directory with a _commands/ folder; the unit you build/train/run.
  • Command — one Python file in _commands/ wrapping a piece of app logic; the unit of intent.
  • Agent mode — an LLM ReAct agent plans and calls workflow commands as tools (default for run).
  • Assistant mode — deterministic: your message goes straight through intent detection → parameter extraction → execution, no agent loop.
  • Turn — one user message processed end-to-end, producing a TurnOutput.
  • Channel — the server's session identity (channel_id); one conversation stream per channel.
  • MCP — Model Context Protocol; the server auto-exposes selected endpoints as MCP tools at /mcp.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
