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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00514 |
| Opus 5 | $0.00000 | $0.00257 |
| Sonnet 5 | $0.00000 | $0.00103 |
| Haiku 4.5 | $0.00000 | $0.00051 |
Grade A, and why
goose 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 3d 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.
What it actually says
Watch Skill in Goose
Status: doc-verified ☑ — config matches Block's official Goose docs; not executed here.
Goose calls MCP servers "extensions"; a command-line extension is exactly our stdio server.
Install
uvx --from "watch-skill[standard]" watch-skill doctor
uvx fetches the package on first use and needs no checkout. Prefer a
permanent install? pipx install "watch-skill[standard]", then use
"command": "watch-skill", "args": ["serve"] in the config below.
git clone https://github.com/oxbshw/watch-skill && cd watch-skill
uv sync --extra all
uv run watch-skill doctor
Then run watch-skill setup, which writes the config pointing at your
checkout rather than the published package.
Configure
Either run goose configure → Add Extension → Command-line Extension
and enter the command below, or add the block to
~/.config/goose/config.yaml yourself:
extensions:
watch-skill:
name: Watch Skill
type: stdio
enabled: true
cmd: uvx
args: ["--from", "watch-skill[standard]", "watch-skill", "serve"]
timeout: 300
timeout: 300 matters: a first watch_video on a long clip is a real
pipeline (download, frames, OCR, transcription), not a quick lookup.
Smoke test (3 steps)
goose session, then: "Watch https://www.youtube.com/watch?v=aqz-KE-bpKQ and tell me what happens at 0:10."- Approve the
watch_videocall. - Follow up: "what color is the bird?" — should call
ask_video, no re-processing.
Notes
- Goose is model-agnostic; Watch Skill's report is plain text + image blocks, so any model Goose drives can read at least the text. Frame paths are in the text for models without vision.
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.

goose is an agent published in the GitHub repository oxbshw/watch-skill (320 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 514 tokens. 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.
