microsoft/cat-agent-skills is a static website that catalogs reusable instruction sets and related packages for AI agents. People use it to search, filter, rate, and download skills for Cowork, Copilot Studio, and Scout, along with Copilot plugins and Scout automations. The catalogue entries are the skills, instructions, plugins, and settings displayed by the site.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 5.1 | $0.00153 | $0.03428 |
| Opus 5.5 | $0.00061 | $0.01371 |
| Sonnet 5.5 | $0.00031 | $0.00686 |
| Haiku 4.5 | $0.00015 | $0.00343 |
Grade A, and why
create-playbook 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.
How it starts
The opening of the file, as written. The whole thing — 262 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create playbook
Build a reviewable draft contract review playbook from documents the user
identifies as precedents — signed or executed agreements, approved templates, or
drafts carrying the user's own side's negotiation markup — and deliver it as one
.docx. Never modify a
source precedent.
This workflow is evidence synthesis, not contract review. It identifies recurring positions across the precedents; it does not turn frequency into policy, assert enforceability, or make unresolved legal and commercial decisions for counsel.
When NOT to Use
- Producing a new agreement, clause set or template from one precedent. This skill writes guidance about instruments, not the instrument itself.
- Reviewing, redlining or advising on a single agreement — use
review-contract. - Explaining what changed between marked-up versions — use
summarize-redlines. - Field-by-field tabular extraction across documents — use
compare-key-terms. - Obligations and deadlines into a tracker — use
extract-obligations-and-deadlines. - A written memorandum of advice — use
draft-legal-memo. - Any request for legal advice, enforceability opinions or risk scoring, and any document the user has not identified as a precedent for this exercise.
Hand-off rule. If a request, or part of one, matches an item above that names
another skill, do not do that part here — even when the documents are already open
and the work looks quick. Name the skill that handles it (for example, "That part
is a job for review-contract") and stop that part; finish only what belongs to
this skill. If the named skill is not installed, say so plainly and do not attempt
it here.
Known limitations
There is no live Word surface and no in-place editing or commenting: sources are
read as files and the deliverable is a new .docx. There is no block-id citation
mechanism — evidence is cited by exact filename plus a reader-facing locator and a
short verbatim quotation.
Step 1: Scope the corpus
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

create-playbook is a skill published in the GitHub repository microsoft/cat-agent-skills (101 stars, last pushed yesterday), licensed MIT. It adds 153 tokens to every session and 3,428 once invoked, about $0.0006 per session on Opus 5.5. 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 2026-11-06.
