Claude Video is an agent add-on that lets Claude analyze videos by obtaining captions, downloading media, extracting frames, and producing timestamped transcripts. It is used to answer questions about online or local videos, including their visual content, audio, structure, and opening moments. Catalogue add-ons provide the commands, hooks, instructions, and skill that enable this workflow.
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 | $0.00916 | $0.00916 |
| Opus 5 | $0.00458 | $0.00458 |
| Sonnet 5 | $0.00183 | $0.00183 |
| Haiku 4.5 | $0.00092 | $0.00092 |
Grade A, and why
claude-video AGENTS.md 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 6d 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 — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.
claude-video / watch skill
Agent Skills package that gives an agent a video input. Installable across Claude Code (most common host), Codex, Cursor, GitHub Copilot, and 50+ other Agent Skills hosts. Pure-stdlib Python that orchestrates yt-dlp + ffmpeg and an optional Whisper API.

Orientation
- The product is the slash-command-invoked skill (
/watch <url-or-path> [question]), not a CLI.scripts/watch.pyis implementation. Features must work across every harness the skill installs into, not just Claude Code. - The skill is one self-contained folder:
skills/watch/. SKILL.md andscripts/are siblings inside it. This is what letsnpx skills addcopy a working skill as a unit — do NOT move SKILL.md orscripts/back to the repo root, or non-Claude installers will copy SKILL.md without the scripts. - Path resolution is harness-agnostic. SKILL.md resolves
SKILL_DIRas the directory of the SKILL.md the model just Read, then runs${SKILL_DIR}/scripts/.... Do NOT reintroduce${CLAUDE_SKILL_DIR}(Claude-Code-only) — it is unset on Codex/Cursor/agents and breaks every script call there. - No
commands/wrapper./watchis derived from SKILL.md frontmatter (name: watch+user-invocable: true). A separate command file creates a duplicate slash command.
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.

claude-video AGENTS.md is an instructions file published in the GitHub repository bradautomates/claude-video (16,806 stars, last pushed 2mo ago), licensed MIT. It adds 916 tokens to every session, about $0.0046 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.
