microsoft/win-dev-skills is a collection of AI-agent instructions and tools for creating native Windows applications with WinUI 3 and the Windows App SDK. Windows developers use it to guide agents through app development tasks from scaffolding and design to testing, packaging, and release. The catalogue entries are its agents, skills, and plugin components.
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 5.1 | $0.00058 | $0.00948 |
| Opus 5.5 | $0.00023 | $0.00379 |
| Sonnet 5.5 | $0.00012 | $0.00190 |
| Haiku 4.5 | $0.00006 | $0.00095 |
Grade A, and why
windbg-kernel-irp-lifecycle-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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
IRP Lifecycle Triage
Load windbg-diagnostic-method first if it is not already loaded in this
conversation, and apply it throughout for evidence ranking, hypothesis testing,
confidence calibration, independent review, and report validation. This skill
adds the bug-family-specific commands and evidence requirements.
Scope
Investigate I/O Request Packets in a kernel dump or authorized live kernel
session. Examples include 0x9F power failures and hangs where progress
depends on a driver request. Apply the parameter table for the specific
bugcheck subtype rather than assuming every 0x9F identifies the same object.
For 0x9F with P1 equal to 3, P4 is the blocked IRP. Inspect that directly
before running a system-wide search.
Workflow
1. Decode the known request
!analyze -v
!irp <irp-address>
When no request address is known and the dump has the required pool data:
!irpfind
!irpfind can be expensive in a live session and incomplete in a limited dump.
Use supported filters where appropriate. No result does not prove there are
no outstanding requests.
2. Follow the stack and ownership
Record the major/minor operation, current stack location, device/driver stack, completion routine, pending flags, cancellation state, and any relevant thread. Use the available device stack and driver source to establish which component is expected to advance or complete the request.
Do not identify an offending driver solely by the last name printed in the IRP stack. A completion routine, downstream dependency, or framework-owned request may change the responsible path.
3. Correlate dependencies
| Evidence | Next investigation |
|---|---|
| I/O verifier violation or available shadow history | windbg-kernel-verifier-triage |
| Owner/waiter kernel lock chain | windbg-kernel-lock-deadlock-triage |
| Exception or trap during request handling | windbg-kernel-bugcheck-triage |
Preserve evidence between skills; avoid repeatedly handing the same unchanged IRP back and forth.
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.

windbg-kernel-irp-lifecycle-triage is a skill published in the GitHub repository microsoft/win-dev-skills (472 stars, last pushed 2d ago), licensed MIT. It adds 58 tokens to every session and 948 once invoked, about $0.0002 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 2026-10-08.
