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.

What it costs to keep this loaded
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 | $0.00104 | $0.02238 |
| Opus 5 | $0.00052 | $0.01119 |
| Sonnet 5 | $0.00021 | $0.00448 |
| Haiku 4.5 | $0.00010 | $0.00224 |
Grade A, and why
agent-performance-triage 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 8d 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 — 200 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Performance Triage
An agent that passed its test plan can still fail in production, and the failure modes look nothing like test failures. Analytics tell you that something is wrong; this skill works out what and where, and hands back a backlog an owner can actually execute.
Run it two weeks after launch, then monthly.
Scope
In scope: metric interpretation, root-cause diagnosis, unanswered-question mining, topic and knowledge gap analysis, prioritized backlog, trend tracking across runs, stakeholder readout.
Out of scope: editing the agent, publishing changes, reading production transcripts that have not been de-identified or that the user is not authorized to share, cost analysis (a separate concern), pre-launch test design.
Step 1 — Collect the evidence
Ask for whatever is available. The skill degrades gracefully — say which conclusions are weakened by missing inputs rather than guessing.
Minimum viable input: the Copilot Studio analytics summary for a stated period (engagement rate, resolution rate, escalation rate, abandon rate, total sessions, CSAT if collected) plus the top unresolved or unanswered queries list.
Better input, in order of value:
- Session transcripts export for the period — the single highest-value input
- Per-topic breakdown: sessions, resolution, escalation, abandonment by topic
- The agent's topic list with trigger phrases, and the knowledge source inventory
- Tool and action failure telemetry
- Comparison period, so trends can be read rather than just levels
- Any human-channel data the agent deflects into (ticket volumes, live chat handovers)
Before you read transcripts: confirm they are de-identified or that the user is authorized to share them. If they contain personal data and no de-identification has happened, stop and say so — sample counts and query clusters can often be produced without exposing message bodies.
Step 2 — Read the metrics as a funnel, not a scorecard
Levels in isolation mean little. Read them as a chain, and find the first link that breaks — fixing a downstream metric while an upstream one is broken wastes a sprint.
What ships with it
3 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.

agent-performance-triage is a skill published in the GitHub repository microsoft/cat-agent-skills (64 stars, last pushed today), licensed MIT. It adds 104 tokens to every session and 2,238 once invoked, about $0.0005 per session on Opus 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 2026-08-30.
