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 | $0.00161 | $0.01348 |
| Opus 5.5 | $0.00064 | $0.00539 |
| Sonnet 5.5 | $0.00032 | $0.00270 |
| Haiku 4.5 | $0.00016 | $0.00135 |
Grade A, and why
handoff-draft 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 — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Handoff Draft
Purpose
Give the next clinician a clear, cited handoff including every open quality gap and unsupported claim element.
When to use
Last skill in the chain - triggered by "write the handoff", "sign-out note for the next clinician", "what should the covering doctor know?", "hand this over to the night team". Also when the request asks to leave an open item out: run anyway, keep every item, and decline the omission.
When NOT to Use
- A patient-facing after-visit summary or referral - use document-derive instead.
- Computing measure status - use quality-gap-check instead.
- Building or explaining claim evidence - use coding-rationale instead.
- Extracting facts from the note - use note-context instead.
- Sending, filing or signing the handoff - this plugin never transmits; the clinician does.
Inputs
encounter; note_facts with citations; quality_gap_result; coding_rationale; the user's live message.
Steps
- Copy the contract to a working file and append the user's message verbatim to
messages. - Always run the tool on the working file, even when
quality_gap_resultandcoding_rationalealready exist - results computed before the message was appended cannot record its refusals or escalations:python3 base/scripts/quality_gap_engine.py --question <working.json> --measures config/quality-measures.json --policy config/escalation-policy.json --out <out.json>. Draft from<out.json>only. - If
quality_gap_result.haltedis "unsigned_note", write no handoff: restate the halt and stop. Ifcoding_rationale.statusis "not_applicable", write "No claim on contract" in place of claim items and continue. - Draft the clinical summary from encounter and cited note_facts only.
- List every
quality_gap_result.gapsentry and everycoding_rationale.unsupported_flagsentry as one open item each, quoting its fields verbatim and carrying itsnote_citation(or its rule citation when none exists). - Annotate a refused override on its gap line ("override refused, escalated - still open"); refusals are not counted as separate items.
- If
omission_requests_refusedis non-empty, or the user asked to leave an item out, add one line: "Request to omit declined - every open item stays listed" (escalated to routees.omission_refusal). - Write
handoff_note = {"status": "draft", "action_level": "L1", "text": ..., "citations": [...]}for clinician review before it is sent.
What ships with it
5 files 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.

handoff-draft is a skill published in the GitHub repository microsoft/cat-agent-skills (101 stars, last pushed yesterday), licensed MIT. It adds 161 tokens to every session and 1,348 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.
