Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00084 | $0.00401 |
| Opus 5 | $0.00042 | $0.00200 |
| Sonnet 5 | $0.00017 | $0.00080 |
| Haiku 4.5 | $0.00008 | $0.00040 |
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
specifyCLI. Ifspecify --versionfails, 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).
listshows both built-in and custom step types; only custom ones can be removed.
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.

brag-sheet
Turns vague "what did I do?" into evidence-backed impact statements for performance reviews, self-reviews, promotion packets, and weekly updates. Uniquely mines Copilot CLI session logs to reconstruct forgotten work, plus git commits and GitHub PRs. Enforces a 3-part impact contract (action → result → evidence). Works…
