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 | $0.00087 | $0.01492 |
| Opus 5 | $0.00044 | $0.00746 |
| Sonnet 5 | $0.00017 | $0.00298 |
| Haiku 4.5 | $0.00009 | $0.00149 |
Grade A, and why
onenote-desktop 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 — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OneNote Desktop
Use desktop OneNote COM directly. Prefer scripts/Invoke-OneNoteCom.ps1 for known operations, but do not treat it as a limit: when the task needs a capability the helper lacks, write a focused one-off PowerShell COM script and run it with Windows PowerShell STA.
Always use this shell shape for COM:
powershell.exe -NoProfile -STA -ExecutionPolicy Bypass -Command '<OneNote COM code>'
or:
powershell.exe -NoProfile -STA -ExecutionPolicy Bypass -File .\scripts\Invoke-OneNoteCom.ps1 <args>
Do not use pwsh for OneNote COM unless you just smoke-tested the exact call. Office COM is apartment-sensitive; powershell.exe -STA is the reliable baseline.
Quick Start
Check desktop OneNote and COM:
powershell.exe -NoProfile -STA -ExecutionPolicy Bypass -File .\scripts\Invoke-OneNoteCom.ps1 -Operation check-install
List visible notebooks, sections, and pages:
powershell.exe -NoProfile -STA -ExecutionPolicy Bypass -File .\scripts\Invoke-OneNoteCom.ps1 -Operation hierarchy -Scope pages
Read a page:
powershell.exe -NoProfile -STA -ExecutionPolicy Bypass -File .\scripts\Invoke-OneNoteCom.ps1 -Operation get-page -PageId "<page-id>"
Export a page to PDF:
powershell.exe -NoProfile -STA -ExecutionPolicy Bypass -File .\scripts\Invoke-OneNoteCom.ps1 -Operation publish -PageId "<page-id>" -TargetPath ".\exports\page.pdf" -PublishFormat pdf
Create a page:
powershell.exe -NoProfile -STA -ExecutionPolicy Bypass -File .\scripts\Invoke-OneNoteCom.ps1 -Operation create-page -SectionId "<section-id>" -Title "Agent note" -Text "Written by an agent through OneNote COM."
Extract audio/media from a page:
powershell.exe -NoProfile -STA -ExecutionPolicy Bypass -File .\scripts\Invoke-OneNoteCom.ps1 -Operation extract-media -PageId "<page-id>" -OutputDir ".\media-export"
Workflow
- Run
check-install. - Run
hierarchy -Scope pagesand identify the target notebook/section/page. - If hierarchy is empty, COM is working but no notebooks are open in this OneNote profile/session. Ask the user to open the notebook or create a local section with
demo-write. - Use helper operations for routine tasks.
- Use raw COM for anything not yet wrapped. Read
references/raw-com.mdbefore writing new COM code. - For page edits, read existing XML first and preserve namespaces, IDs, timestamps, object IDs, and unknown elements.
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.

onenote-desktop is a skill published in the GitHub repository Takhoffman/onenote-desktop-agent (5 stars, last pushed 2mo ago), licensed MIT. It adds 87 tokens to every session and 1,492 once invoked, about $0.0004 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 2026-08-31.
