otio-docs

otio-docs is a skill for Claude Code from damionrashford/media-os. It costs 198 tokens per session (2,405 once invoked), scanned A, original, MIT.

A reference tool for finding and reading official OpenTimelineIO documentation. OpenTimelineIO is a library and file format for describing video and audio editing timelines, including clips, tracks, transitions, and media references.

In plain words
What is it for?
Use it to look up timeline structures, time ranges and transforms, media references, Python reading and writing, file adapters, tutorials, and related API details.
Why use it?
It helps you verify the available Python classes, functions, adapters, tutorials, and command-line concepts before writing code that uses them.

Token cost

What it costs to keep this loaded

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.

Security

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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/otiodocs.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.Clip take?" 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 / otiostat CLI 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

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.

Changes

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.
