Local Testing

What it does

When your agent uses it

• Verify component
• Test in browser
• Screenshot demo

Example prompts

• “/local-testing”

Workflow steps

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

1. 1Open the canonical documentation path and confirm the expected title.
2. 2Confirm the current sidebar entry through [aria-current="page"].
3. 3Open the manifest-backed standalone route and confirm [data-standalone-demo] exists.
4. 4Exercise every changed interaction using accessible control names.
5. 5Verify relevant light and dark appearance states through [data-demo-appearance].
6. 6Verify desktop and mobile viewport behavior when layout is affected.
7. 7Capture a screenshot for visual evidence and inspect semantic state with eval.
8. 8Drain captured browser errors and inspect the development-server log.

What it can do on your machine

Read from SKILL.md and the folder at commit 6b4ecd3. 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

  Shell commands in SKILL.md call:

  • pnpm
  • jq
  • curl
  • rg

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

• Network

  No URLs in SKILL.md. Its commands use pnpm and curl, which can reach the network depending on how they are called.

  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

Local Testing loads about 2.1k tokens when it runs. Until then it costs about 93 tokens; SKILL.md has 526 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~93

When it runs · the whole SKILL.md, loaded when a task matches

~2.1k

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

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.

description

Local browser verification for the lobe-ui component library and documentation site. Uses agent-browser against the React Router and Vite development server, including component pages, manifest-backed standalone demos, theme states, and responsive layouts. Trigger on local test, UI test, verify component, test in browser, visual check, or screenshot demo.
