speckit-workflow-step

A command-line tool for managing workflow step types in Spec Kit. Step types are the reusable building blocks that workflow files refer to.

In plain words
What is it for?
Use it to list, search, inspect, install, remove, or manage catalog sources for built-in and custom workflow steps.
Why use it?
It helps ensure a workflow has the step types it needs and lets you inspect or manage the available catalog sources.

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 A, and why

speckit-workflow-step scanned grade A with 0 findings 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 2d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Spec Kit — workflow step types

Manage the step types that workflows are composed of, using the Specify CLI specify workflow step command group. (Requires Specify CLI >= 0.11.)

Prerequisite: needs the specify CLI. If specify --version fails, install it with the speckit-cli-setup skill first.

When to use

  • Inspect which step types (built-in or custom) are available to workflows.
  • Install or remove a custom step type, or manage step-type catalog sources.

How to invoke

# Discover step types
specify workflow step list
specify workflow step search <query>
specify workflow step info <step-id>

# Install / remove custom step types
specify workflow step add <step-id>            # from the step catalog
specify workflow step remove <step-id>

# Manage step catalog sources
specify workflow step catalog list
specify workflow step catalog add <url>
specify workflow step catalog remove <index>   # by index

Notes

  • Step types are the building blocks referenced by workflow YAML; install the step types a workflow needs before running it (see the speckit-workflow skill).
  • list shows both built-in and custom step types; only custom ones can be removed.
Changes

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.

speckit-workflow-step is a skill published in the GitHub repository github/spec-kit-copilot (11 stars, last pushed 7d ago), licensed MIT. It adds 84 tokens to every session and 401 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
