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.

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 | $0.00162 | $0.02581 |
| Opus 5.5 | $0.00065 | $0.01032 |
| Sonnet 5.5 | $0.00032 | $0.00516 |
| Haiku 4.5 | $0.00016 | $0.00258 |
Grade A, and why
check-execution-readiness 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 — 225 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Check execution readiness
Review the complete supplied document and give the user a clear, read-only assessment of whether it appears ready for execution. Identify document-completion issues involving parties, dates, signature blocks and unresolved drafting, each carried by an exact quotation attributed to its clause, field, schedule or signature block.
Do not suggest, draft or stage edits. Do not modify the document and do not provide replacement wording.
This is an execution readiness check focused on document completion. It does not provide assurance that the agreement is legally valid, commercially acceptable, properly authorized, or compliant with execution requirements in every applicable jurisdiction.
When NOT to Use
- A defined terms audit or a cross-reference audit of one document — use
check-defined-termsorcheck-cross-references. - Explaining what the open tracked changes actually say or who moved which way —
use
summarize-redlines. This skill flags only that unresolved changes exist. - The current operative position across a master agreement and its amendments —
use
analyze-related-contracts. - A field-by-field key terms table — use
compare-key-terms. - Obligations, deadlines or a post-signature tracker — use
extract-obligations-and-deadlines. - A general question about what a clause says or does — use
legal-reasoning; a written memorandum — usedraft-legal-memo. - Producing or editing a file — a Word document, workbook, deck or PDF — use
docx,xlsx,pptxorpdf. This skill creates no file and changes none. - Advising whether the agreement is enforceable, validly executed, properly authorized, or should be signed — out of scope entirely; see Guardrails.
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 check-defined-terms") 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.
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.

check-execution-readiness is a skill published in the GitHub repository microsoft/cat-agent-skills (101 stars, last pushed yesterday), licensed MIT. It adds 162 tokens to every session and 2,581 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.
