chrome-browser-control: Skill for Claude Code

.cursor/skills/npm-release/SKILL.md

npm-release is a skill for Claude Code, Cursor from vKongv/chrome-browser-control. It costs 66 tokens per session (2,025 once invoked), scanned A, original, MIT.

A release skill for the chrome-browser-control npm package, a JavaScript package distributed through npm. It checks the package, updates its semantic version, and prepares an npm publication and a matching GitHub release.

In plain words
What is it for?
Use it to prepare a new package version, run pre-publish checks, update release files, prepare a version tag, and draft the corresponding GitHub release.
Why use it?
It gives maintainers a repeatable release checklist and keeps the package version aligned across its manifest files. Publishing and two-factor authentication still require a human maintainer.

Skill for Claude CodeCursor

Written for Claude Code and Cursor: disable-model-invocation in frontmatter, but also installed under .cursor/.

This is vKongv/chrome-browser-control's own configuration. It tells Claude Code and Cursor how to work on chrome-browser-control itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything chrome-browser-control configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node /tmp/cbc-pack-smoke/package/dist/cli/main.js --help.

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

npm-release 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 5d 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 — 205 lines — stays where its author put it; the contents beside it link to each section on GitHub.

chrome-browser-control — npm release

Manual semver release for the public npm package chrome-browser-control. Agents prepare and verify; humans run npm login, 2FA, and npm publish.

Detailed maintainer checklist: docs/publish-checklist.md

When to use / when NOT to use

Use this skill Do NOT use pbstack github-release
npm package chrome-browser-control Web-app production deploys (gusto-be, admin FE, etc.)
Semver tags vX.Y.Z (e.g. v0.1.1) Date tags YYYYMMDD-NNN
npm publish from maintainer laptop Draft GitHub releases from merged-PR changelogs
Published (non-draft) GitHub Release after npm succeeds Linear/client deployment summaries

github-release compares master to last release, builds PR changelogs, and drafts releases. This repo publishes to npm first, tags vX.Y.Z on main, and ships a published GitHub Release — a different contract entirely.

Version bump checklist

Bump both files to the same semver before opening a release prep PR:

File Field
package.json "version"
extension/manifest.json "version"

Also keep package-lock.json and docs/publish-checklist.md “Current release target” aligned.

Choosing the bump

Use a minor release for small changes; use a major release for large ones.

Maintainer label Typical scope Semver on 0.x Example
Minor release Default tweaks, skill/docs, small fixes, narrow behavior polish Bump patch (0.Y.Z0.Y.Z+1) 0.3.00.3.1
Major release New tool surfaces, architecture shifts, broad breaking defaults Bump minor (0.Y.Z0.Y+1.0) 0.3.x0.4.0

Reserve semver major (1.0.0) for a stability / public API contract milestone. When unsure, prefer a minor (patch) release.

Confirm package.json "files" still excludes skills/ (only dist, extension, package.json, README.md). The agent skill under skills/chrome-browser-control/ is not in the npm tarball — install from git or skills.sh separately.

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.
