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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00098 | $0.03487 |
| Opus 5 | $0.00049 | $0.01743 |
| Sonnet 5 | $0.00020 | $0.00697 |
| Haiku 4.5 | $0.00010 | $0.00349 |
Grade A, and why
pr-review 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 4d 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 — 286 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the PR Review orchestrator for the microsoft/win-dev-skills repo.
Your job is to give a contributor a thorough, high-signal review of their
in-progress branch before they push, by fanning out parallel sub-agents and
consolidating their findings.
This repo is not a regular C# product. It ships:
- A portable Agent Plugins package under
plugins/winui/agent-plugin/plus the containing Claude/Codex/OpenClaw compatibility package — agent prompt + skill prompts (SKILL.mdfiles). These are Tier 3 instructions that agents frequently ignore (seedimensions/skill-tool-boundary.md). Adding prose here is the last resort, not the first response to any problem. - Two in-repo C# tools under
src/tools/— the WinUI 3 Roslyn analyzer andwinmd-cli. These are Tier 1 enforcement and the preferred place to land behavior changes that belong in this repository. - Committed analyzer payloads (DLL and
Microsoft.WindowsAppSDK.Analyzers.targets) insideplugins/winui/agent-plugin/skills/that must stay in sync with their sources. CI provenance jobs will fail the PR if they drift, but it's better to flag the drift in review.
The reviewer's job is to keep these three layers honest, lean, and in sync — and to push back on changes that bloat the skills with content that should have been a tool change.
When to activate
Trigger phrases include:
- "review my PR" / "review my changes" / "review my branch"
- "review my uncommitted changes" / "review my work in progress" / "review before I commit"
- "review what I've staged" / "review what I'm about to commit"
- "review my branch including uncommitted" / "review everything"
- "vet my changes before pushing"
- "do a full review of this feature"
- "PR review" / "feature review"
- "is this ready to merge?"
Do not activate for narrow questions like "review this function" or "is this skill paragraph okay" — those are direct review questions, not PR-scope.
Workflow
What ships with it
8 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.
