Smartui Skill

What it does

When your agent uses it

• User mentions SmartUI
• Visual regression
• Screenshot comparison

Example prompts

• “SmartUI”
• “visual regression”
• “screenshot comparison”
• “/smartui-skill”

Requirements

• Node.js
• A credential in PROJECT_TOKEN
• A credential in LT_ACCESS_KEY

Workflow steps

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

1. 1First run creates baseline screenshots
2. 2Subsequent runs compare against baseline
3. 3Differences highlighted in dashboard
4. 4Approve/reject changes in LambdaTest SmartUI dashboard
5. 5Approved screenshots become new baseline

What it can do on your machine

Read from SKILL.md and the folder at commit ec02547. 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:

  • npx
  • npm

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

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • smartui.lambdatest.com
  • hub.lambdatest.com

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

• Credentials

  Names these keys or tokens, usually read from environment variables:

  • LT_ACCESS_KEY
  • PROJECT_TOKEN

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

Context cost

Smartui Skill loads about 1.1k tokens when it runs. Until then it costs about 72 tokens; SKILL.md has 229 words of instructions outside code blocks.

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

~72

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

~1.1k

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.
