windsurf

A setup guide for using Watch Skill inside Windsurf, a coding assistant with an MCP server connection. It covers installation, configuration, refreshing the connection, and a short video test.

In plain words
What is it for?
Use it to add Watch Skill to Windsurf's MCP settings, confirm that its tools appear in the Cascade panel, and ask Windsurf about a YouTube video.
Why use it?
It removes the uncertainty around adding video understanding to Windsurf. It also notes that the documented setup was not run on the guide's machine.

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.

Clone the repo
git clone --depth 1 https://github.com/oxbshw/watch-skill
Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 429 The whole file, excluding the scripts and references it only reads on demand.

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

windsurf 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 2d 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 Windsurf

Status: config verified against official docs, not machine-tested ☑ (Windsurf is not installed on the development machine — please report issues.)

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

Windsurf → Settings → Cascade → MCP Servers → Add ServerAdd custom server, or edit ~/.codeium/windsurf/mcp_config.json directly:

{
  "mcpServers": {
    "watch-skill": {
      "command": "uvx",
      "args": ["--from", "watch-skill[standard]", "watch-skill", "serve"]
    }
  }
}

Press the refresh button in the MCP panel after saving.

Smoke test (3 steps)

  1. The Cascade MCP panel should list watch-skill with its 39 tools.
  2. Cascade prompt: "Use watch-skill to watch https://www.youtube.com/watch?v=aqz-KE-bpKQ and tell me what happens at 0:10."
  3. Follow up: "search my indexed videos for 'bunny'"search_videos.
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.

windsurf is an agent published in the GitHub repository oxbshw/watch-skill (320 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 429 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.
