# "Look at It" Skills: Closing the Verification Loop — Claude Code Skills & SKILL.md

> Give Claude a way to observe the result of its own work.

## Stop asking the human what the screen says

A powerful pattern is a skill that lets Claude **observe the effect of its changes** instead of asking you to look: a **browser skill** that loads a page headlessly and reports console errors, failed network requests, the title and optional DOM checks or a screenshot; a **game or app runner** that starts the program and returns the log; a **test-and-report** skill that runs the suite and summarises failures; an **API smoke test** that calls an endpoint and prints status and a trimmed body. This closes the loop **edit, run, observe, fix** that otherwise needs the human to describe what happened. Design such skills so that they print **concise, structured findings** (not megabytes of logs), have a **timeout**, clean up processes they start, and make clear what was and was not verified. The description should say when to use it ("use to verify your own web changes").

## The verification loop

Each step produces something Claude can read.

```text
edit code
  -> run (start app / load page / run tests)       <- a skill script, with a timeout
  -> observe: console errors? failed requests? failing test? status code?
  -> concise structured findings back to Claude   <- JSON or short labelled lines
  -> fix and repeat until the findings are clean
  -> final report states exactly what was verified (and what was not)
```

## Put a timeout on every run

An app or browser that hangs should not freeze the whole session.

**Quiz:** What does a "look at it" skill remove from the workflow?

- [ ] The need for a computer
- [ ] The need for code
- [ ] The need for tests
- [x] Asking the human to describe what is on the screen or in the log

*Answer:* Asking the human to describe what is on the screen or in the log. Claude can observe results itself and iterate without waiting for a human.
