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 | $0.00198 | $0.02405 |
| Opus 5 | $0.00099 | $0.01203 |
| Sonnet 5 | $0.00040 | $0.00481 |
| Haiku 4.5 | $0.00020 | $0.00241 |
Grade A, and why
otio-docs 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 11d 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 — 191 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OTIO Docs
Context: $ARGUMENTS
Quick start
- Find an OTIO class / function / adapter: → Step 2 (
search --query <term>) - Read the full API section: → Step 3 (
section --page <page> --id <anchor>) - Grab a whole tutorial / API page: → Step 4 (
fetch --page <name>) - Prime cache for offline use: → Step 5 (
index)
When to use
- User asks "what does
otio.schema.Cliptake?" or "how do I subclass Track?" - Need to confirm an adapter exists (EDL, FCP7-XML, FCPXML, AAF, ALE, XGES, SVG) before recommending.
- Need the
otioconvert/otiotool/otiostatCLI surface (CLIs are documented via--help, not readthedocs — this skill pulls the tutorials + Python-API pages instead). - Need to cite the canonical readthedocs URL or GitHub source of truth.
- Before writing OTIO Python code: verify API surface (classes, methods, serialization fields).
Step 1 — Know the page catalog
uv run ${CLAUDE_SKILL_DIR}/scripts/otiodocs.py list-pages
Common picks:
| Question | Page |
|---|---|
| "How do I read/write OTIO from Python?" | tut-quickstart |
| "What's Stack vs Track vs Timeline?" | tut-timeline-structure |
| "How do RationalTime and TimeRange work?" | tut-time-ranges |
| "Which adapters ship natively vs via OpenTimelineIO-Plugins?" | tut-adapters |
| "How do I author a custom schema?" | tut-schemadef |
| "Python API reference root" | api-py-root |
| "opentime module (RationalTime/TimeRange)" | api-opentime |
| "core module (SerializableObject, SerializableCollection)" | api-core |
| "schema module (Timeline/Clip/Gap/Track/Stack)" | api-schema |
| "algorithms module (stack_algo, track_algo, timeline_postprocess)" | api-algorithms |
| "media_linker module" | api-media-linker |
| "hooks module" | api-hooks |
| "README / repo root" | github-readme |
| "OpenTimelineIO-Plugins meta-package (community adapters)" | plugins-readme |
Read references/adapters.md for the full adapter matrix + references/pages.md for the URL catalog.
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.

otio-docs is a skill published in the GitHub repository damionrashford/media-os (18 stars, last pushed 3mo ago), licensed MIT. It adds 198 tokens to every session and 2,405 once invoked, about $0.0010 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…
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…
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…
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 →…
