What it does

Wxt Browser Extensions is an agent skill from vantezzen/skip-silence. WXT browser extension performance optimization guidelines. This skill should be used when writing, reviewing, or refactoring WXT browser extension code to ensure optimal performance patterns. Triggers on tasks involving WXT, browser extensions, content scripts, service workers, messaging, and extension APIs.

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 55 other files, including reference files and assets (for example `README.md`, `assets/templates/_template.md` and `references/_sections.md`).

It sits in Development, covering Browser extensions. It works with Chrome Extensions. The repository describes itself as: 🔇 Browser extension to skip silent parts in videos and audio files on any webpage. The licence is MIT.

When your agent uses it

  • Tasks involving WXT
  • Browser extensions
  • Content scripts
  • Service workers

Example prompts

  • “/wxt-browser-extensions”

Workflow steps

8 steps, taken from the step headings in SKILL.md.

  1. Service Worker Lifecycle (CRITICAL)
  2. Content Script Injection (CRITICAL)
  3. Messaging Architecture (HIGH)
  4. Storage Patterns (HIGH)
  5. Bundle Optimization (MEDIUM-HIGH)
  6. Manifest Configuration (MEDIUM)
  7. UI Performance (MEDIUM)
  8. TypeScript Patterns (LOW-MEDIUM)

What it can do on your machine

Read from SKILL.md and the folder at commit 0506b01. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Wxt Browser Extensions loads about 1.9k tokens when it runs, and up to ~27k if it reads all its reference files. Until then it costs about 83 tokens; SKILL.md has 493 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~83
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~27k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
