Mux docs discovery

Mux publishes its entire documentation as agent-ready markdown, auto-generated from the same source as the real docs site. For any Mux question, fetch the relevant page and answer from it — never answer Mux API questions from memory, because API shapes and guidance change.

Workflow

1. Route. Pick the most specific starting point:
   • A known page URL (see collection indexes below to find one).
   • A collection index for the topic area (small, fast to scan).
   • An API reference bundle or spec (below) for exact request/response shapes.
   • The Mux Robots guides (below) for AI video workflows — summaries, moderation, captions, chapters, and more.
   • https://www.mux.com/llms.txt — the master index of every docs page — when you don't know where the topic lives.
2. Fetch the page's markdown. Every docs page has a markdown version: append .md to its URL (e.g. https://www.mux.com/docs/guides/start-live-streaming.md).
3. Answer from the fetched content and cite the page URL.

Collection indexes

Collection	URL
Core concepts	https://www.mux.com/docs/core.txt
Video: upload, encode, manage assets	https://www.mux.com/docs/guides/video.txt
Uploader: handle user uploads	https://www.mux.com/docs/guides/uploader.txt
Player: embed video playback	https://www.mux.com/docs/guides/player.txt
Data: playback quality and analytics	https://www.mux.com/docs/guides/data.txt
Data integrations: third-party player monitoring	https://www.mux.com/docs/guides/data-integrations.txt
Framework integrations and SDKs	https://www.mux.com/docs/integrations.txt
Example implementations	https://www.mux.com/docs/examples.txt
Pricing and billing	https://www.mux.com/docs/pricing.txt

https://www.mux.com/llms-full.txt is the entire documentation in one file — very large; prefer per-page fetches.

Mux Robots (AI video workflows)

Robots — Mux's AI-powered video workflows — don't have their own collection index; their guides are part of the video collection and the master llms.txt index. Start here:

Resource	URL
Robots overview	https://www.mux.com/docs/guides/robots.md
Robots directives reference	https://www.mux.com/docs/guides/robots-directives.md

Task-specific guides follow the pattern https://www.mux.com/docs/guides/robots-<task>.md, where <task> is one of: summarize, moderate, generate-chapters, ask-questions, find-key-moments, find-scenes, find-best-thumbnails, translate-captions, translate-audio, generate-premium-captions, edit-captions, generate-engagement-insights.

API references and specs

For exact endpoint, parameter, and webhook shapes, prefer these over prose guides:

Resource	URL
Video API reference	https://www.mux.com/docs/api-reference/video.txt
Data API reference	https://www.mux.com/docs/api-reference/data.txt
System API reference	https://www.mux.com/docs/api-reference/system.txt
Full API spec (OpenAPI JSON)	https://www.mux.com/api-spec.json
Webhook spec (JSON)	https://www.mux.com/webhook-spec.json
Mux Player web component API	https://raw.githubusercontent.com/muxinc/elements/refs/heads/main/packages/mux-player/REFERENCE.md
Mux Player React component API	https://raw.githubusercontent.com/muxinc/elements/refs/heads/main/packages/mux-player-react/REFERENCE.md

All of these resources are also discoverable from the docs site itself: every docs page links to "Docs for LLMs" (https://www.mux.com/docs/core/llms-txt), the canonical page describing Mux's llms.txt files and machine-readable bundles. If this skill's URL lists ever drift from reality, that page is the source of truth.

Self-healing

If a docs URL 404s, the docs have likely been reorganized. Do not give up after one 404: fetch https://www.mux.com/llms.txt, search it for the topic, and use the current URL.

Staying in sync

• This skill is distributed from the muxinc/mux-skills repository and ships embedded in the mux CLI. Updating the CLI (brew upgrade mux / npm update -g @mux/cli) updates the embedded skills, and mux skills update refreshes all local copies (including ~/.claude/skills) to match the installed version. For skills decoupled from CLI releases, install the mux@mux Claude Code plugin or pull directly from https://github.com/muxinc/mux-skills.
• The CLI embeds only skill instruction files, never docs content — always fetch docs live using the workflow above. Check mux skills --help for what the installed version offers.

Guardrails

• Cite the docs page URL you answered from.
• If the network is unavailable, say you could not verify against current docs — never guess API request/response shapes from memory.
