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 | $0.00212 | $0.03628 |
| Opus 5 | $0.00106 | $0.01814 |
| Sonnet 5 | $0.00042 | $0.00726 |
| Haiku 4.5 | $0.00021 | $0.00363 |
Grade A, and why
audio-wasapi 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 10d 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.

The opening of the file, as written. The whole thing — 347 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Audio WASAPI
Context: $ARGUMENTS
Quick start
- List all audio endpoints: → Step 1 (
winaudio.py list-devices) - Check current default: → Step 2 (
winaudio.py get-default) - Change default output/input/communications: → Step 3 (
winaudio.py set-default) - Mute / unmute / change volume: → Step 4 (
winaudio.py mute/unmute/volume) - Check if exclusive mode is allowed on a device: → Step 5 (
winaudio.py exclusive-test) - Install VB-Cable virtual cable: → Step 6 (
winaudio.py vbcable-install) - Set up VoiceMeeter virtual mixer: → Step 7 (
winaudio.py voicemeeter-config)
When to use
- User is on Windows and needs terminal / PowerShell-driven audio control.
- User wants to change the default playback/recording/communications device without clicking through Sound settings.
- User wants bit-perfect exclusive-mode output for audiophile playback, or to diagnose why an app can't grab the device in exclusive mode.
- User wants to install a virtual audio cable (VB-Cable, VoiceMeeter) to route system audio into OBS / streaming tools.
- User is debugging a shared-mode vs exclusive-mode mismatch (pops, silence, format negotiation errors).
Not for: macOS (use audio-coreaudio), Linux (use audio-pipewire).
The script exits 2 with a helpful message if run on non-Windows.
Read references/exclusive-vs-shared.md
when the user asks about latency, bit-perfect playback, or
IAudioClient::Initialize errors.
Read references/virtual-cable.md when the user
asks about OBS system-audio capture or VoiceMeeter routing.
Step 1 — List devices
uv run ${CLAUDE_SKILL_DIR}/scripts/winaudio.py list-devices
uv run ${CLAUDE_SKILL_DIR}/scripts/winaudio.py list-devices --kind playback
uv run ${CLAUDE_SKILL_DIR}/scripts/winaudio.py list-devices --kind recording
Calls Get-AudioDevice -List (from the AudioDeviceCmdlets PowerShell module).
If the module isn't installed the PowerShell errors out — install with:
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.

audio-wasapi is a skill published in the GitHub repository damionrashford/media-os (18 stars, last pushed 3mo ago), licensed MIT. It adds 212 tokens to every session and 3,628 once invoked, about $0.0011 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.

loudcheck
Loudness compliance verdicts against formal published standards — EBU R 128, ATSC A/85, or BS.1770 measure-only. Use it when audio or video has to pass a delivery gate: "is this file broadcast-legal?", "will this mix get rejected?", "how far off target is it and what's the exact fix?", batch-checking a delivery…
slideshow
Author a HyperFrames slideshow — a presentation, pitch deck, or interactive deck with discrete slides, fragment reveals, branching, hotspot navigation, and built-in presenter mode with speaker notes; also converts an existing page into a deck. Output is a navigable deck, not a rendered MP4. If the user didn't…
faceless-explainer
Turn arbitrary text — an article, notes, a topic, a brief — into a faceless explainer video: there is no site or footage to capture, so the visuals are invented per scene (typography, abstract graphics, diagrams, data-viz). Use for topic explainers, concept breakdowns, how-tos, listicles. Not a video built from a…
figma
Import Figma content into a HyperFrames composition — rendered assets, brand tokens, components, storyboard sections → reconstructed motion (frames read as states, not slides) (REST/CLI), connector-assisted motion when available, and shaders from a connector or native export. Use when the user pastes a figma.com link…
general-video
Author or edit a custom HyperFrames composition when no specialized workflow fits, or when BRIEF.md sets flow: companion. Use for longer or multi-scene pieces, brand and sizzle reels, montages, static loops, static title cards, footage remixes, and freeform builds. Use motion-graphics instead for a short unnarrated…

Port an existing Remotion (React) composition's source to HyperFrames HTML. Use ONLY on an explicit ask to port/convert/migrate/translate a Remotion source — one-way, Remotion-only. A passing Remotion mention, reference-only code, or "make something like my Remotion video" is a fresh build (/general-video). Unclear →…
