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 | $0.00172 | $0.03214 |
| Opus 5.5 | $0.00069 | $0.01286 |
| Sonnet 5.5 | $0.00034 | $0.00643 |
| Haiku 4.5 | $0.00017 | $0.00321 |
Grade A, and why
compare-across-jurisdictions 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 — 242 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Compare across jurisdictions
Answer one question for a litigator or in-house lawyer: on this specific legal point, what does each named jurisdiction say, and where do they diverge? Produce a neutral comparative research memo for counsel review. Never recommend a forum, predict an outcome, choose governing law, or assert that doctrines are equivalent.
Use one of two modes, both on a single frozen framework:
- Requirements comparison — statutory or regulatory entitlements, thresholds, notice, eligibility, filing duties, penalties.
- Litigation treatment — source of law, controlling authority, test, burden and standard of proof, procedure, evidence, remedies, limitation.
When NOT to Use
- Testing a document against legal or regulatory standards — use
identify-regulatory-gaps. If the user asks how the law differs and a document is merely attached, run this skill and state that the document was not tested. - Comparing contract wording across agreements — use
compare-key-terms. - Deriving positions from precedent — use
create-playbook. - A single-jurisdiction question or a reasoned advice memo — use
legal-reasoningordraft-legal-memo. - Drafting or redlining — use
edit-contract. - General non-legal research — use Cowork's built-in in-depth web research.
- Recommending a forum or governing law, or predicting an outcome — declined
outright and recorded under
Not answered.
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 identify-regulatory-gaps") 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: Delivery default
Deliver the complete cited comparison In chat unless the user explicitly requests Word, Excel or another format. Do not ask a delivery format question. A later request to convert completed research into a file does not require repeating the research. If another format is requested, proceed only where an available creation path can produce and validate it; otherwise explain and offer Chat, Word or Excel.
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.

compare-across-jurisdictions is a skill published in the GitHub repository microsoft/cat-agent-skills (101 stars, last pushed yesterday), licensed MIT. It adds 172 tokens to every session and 3,214 once invoked, about $0.0007 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.
