What it does

Website Devtools is an agent skill from oocx/tfplan2md. Use browser tools to inspect rendering and troubleshoot website issues with the Maintainer.

Its SKILL.md is about 390 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. The repository describes itself as: Convert terraform plans (json) into human readable markdown for easier review of changes in pull requests. The licence is MIT.

When your agent uses it

  • Development work in your project

Example prompts

  • “/website-devtools”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Ensure the site is available via the VS Code preview server (http://127.0.0.1:3000/website/dist/), then open the relevant page with…
  2. Use browser/readPage, browser/clickElement, browser/hoverElement, browser/typeInPage, browser/runPlaywrightCode, and screenshots as needed…
  3. When a shared layout, component, partial, or client-side module is under investigation, validate more than one consuming page.
  4. Share findings with the Maintainer and propose the smallest fix.

What it can do on your machine

Read from SKILL.md and the folder at commit 88d5240. 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

Website Devtools loads about 391 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 159 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~27
When it runs · the whole SKILL.md, loaded when a task matches
~391

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.

Skill Instructions

Purpose

Provide a repeatable way to use browser tools during website work to validate rendering, diagnose layout or CSS issues, and troubleshoot together with the Maintainer.

Hard Rules

Must
  • Use the browser/* tools when diagnosing rendering, layout, or interaction issues.
  • Capture concrete findings (console errors, computed styles, DOM structure) and summarize them in the PR/issue.
Must Not
  • Do not guess at rendering behavior when you can verify it in the browser preview.

Golden Example

text
Use browser tools to:
- Inspect computed styles and layout for a problematic element
- Check console for errors
- Verify responsive behavior by simulating viewports

Actions

  1. Ensure the site is available via the VS Code preview server (http://127.0.0.1:3000/website/dist/), then open the relevant page with browser/openBrowserPage.
  2. Use browser/readPage, browser/clickElement, browser/hoverElement, browser/typeInPage, browser/runPlaywrightCode, and screenshots as needed to inspect:
    • DOM structure and element attributes
    • Computed CSS and layout metrics
    • Console logs and runtime errors
    • Network requests (if applicable)
  3. When a shared layout, component, partial, or client-side module is under investigation, validate more than one consuming page.
  4. Share findings with the Maintainer and propose the smallest fix.
