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 | $0.00163 | $0.02995 |
| Opus 5.5 | $0.00065 | $0.01198 |
| Sonnet 5.5 | $0.00033 | $0.00599 |
| Haiku 4.5 | $0.00016 | $0.00299 |
Grade A, and why
draft-legal-memo 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 — 231 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Draft legal memo
Produce a formal legal memorandum that answers a defined legal issue for a named audience, from the perspective of a named represented party, grounded in at least one document the user supplied. It is a draft for counsel review — never legal advice, never a final opinion, never an enforceability determination.
When NOT to Use
- Drafting, negotiating or redlining clause wording — use
edit-contract. This skill never writes contractual language. - Producing a new agreement from a precedent — use
draft-new-contract. - Pulling obligations, rights or deadlines into a tracker — use
extract-obligations-and-deadlines. - A dated timeline of events in a dispute — use
build-case-chronology. - Explaining what changed between marked-up versions — use
summarize-redlines. - Compiling a signing bundle — use
check-execution-readiness. - A short reasoned answer with no memo deliverable — use
legal-reasoning. - Plain file format conversion or general research with no legal question — use Cowork's built-in Word, PDF, document question answering or in-depth web research capabilities.
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 edit-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.
Step 1: Required delivery decision
The output medium defines the deliverable and the execution path; it is not a formatting preference and must not be inferred. If the user already stated one, honor it. Otherwise your first action is a question card, whose first question is Where would you like the output delivered? offering In chat, As a Word document (recommended) and Another file format (type it below). Stop and wait. Words such as "draft", "prepare", "memo" or "report" do not themselves select a medium. If a requested format cannot be produced and validated by an available creation path, say so and offer the supported choices.
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.
