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 | $0.00045 | $0.00700 |
| Opus 5 | $0.00023 | $0.00350 |
| Sonnet 5 | $0.00009 | $0.00140 |
| Haiku 4.5 | $0.00005 | $0.00070 |
Grade A, and why
blog-content-auditor 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 12d 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 — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Blog Content Auditor
Use this skill to audit individual blog posts or a wider blog library and produce a prioritised improvement plan.
Scope options
The skill can handle:
- A single post supplied as text or a URL.
- A list of posts supplied by the user.
- A blog index if the agent has suitable web or content access.
- Draft posts before publication.
- Existing thought-leadership libraries that need rationalisation.
Evidence rules
- Audit only posts that are supplied or accessible.
- Do not invent traffic, ranking, engagement, conversion, recency, or SEO performance data.
- If the user wants performance analysis and no analytics are available, state that analytics were not available and assess editorial quality only.
- Quote or reference specific observed features when justifying recommendations.
Default audit dimensions
Score each post from 0 to 5 for:
- Reader promise - Is the post clear about why the reader should care?
- Opening strength - Does the opening create relevance quickly?
- Argument shape - Is there a coherent point of view, not just a list of observations?
- Evidence and examples - Are claims supported by examples, experience, references, or practical detail?
- Structure and scanability - Is the post easy to navigate?
- Distinctiveness - Does it avoid generic commentary?
- Next action - Does the post help the reader think or act differently?
Workflow
- Identify the available posts and the audit objective.
- Read each accessible post fully enough to assess the dimensions.
- Score each dimension with evidence.
- Identify content that should be kept, refreshed, merged, expanded, or retired.
- Produce a prioritised editorial backlog.
- If relevant, identify themes missing from the current library.

What ships with it
2 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.

blog-content-auditor is a skill published in the GitHub repository microsoft/cat-agent-skills (69 stars, last pushed today), licensed MIT. It adds 45 tokens to every session and 700 once invoked, about $0.0002 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.
