In plain words
What is it for?

Why use it?
It removes leftover browsers, servers, blocked ports, and optionally test data that can interfere with the next test run.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is rm -f ./test-output/.dev-server.json.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

web-test-cleanup scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/cleanup.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Test Cleanup

Clean up test sessions by closing browsers, stopping dev servers, freeing ports, and optionally removing test data.

When to Use This Skill

  • BEFORE starting new tests - Run without --keep-data to get a clean slate
  • AFTER completing tests - Run with --keep-data to preserve test artifacts for review
  • When tests are stuck - Kill hanging browser or server processes
  • When ports are blocked - Free common dev ports (3000, 5173, 8080, 4200, 4321)

Quick Start

SKILL_DIR="<path-to-this-skill>"

# Full cleanup (removes test-output folder)
$SKILL_DIR/scripts/cleanup.sh

# Keep test data (screenshots, wallet config, etc.)
$SKILL_DIR/scripts/cleanup.sh --keep-data

What Gets Cleaned Up

Dev Server Stopped

  • Reads test-output/.dev-server.json to find and stop the dev server process started by web-test
  • Only kills the specific process we started, NOT other processes on common ports

Processes Killed

  • Test browser processes (Chrome/Chromium using test-output profile)
  • Browsers using remote-debugging-port 9222

Ports Freed

  • The port used by our dev server (as recorded in .dev-server.json)
  • Does NOT kill other processes on common ports to avoid affecting unrelated services

State Files Cleaned

  • .browser-cdp.json - Browser CDP connection info
  • .browser-state.json - Browser state
  • .dev-server.json - Dev server process info

Files Removed (unless --keep-data)

├── screenshots/                      # Test screenshots

Instructions

Pre-Test Cleanup (Fresh Start)

Before starting a new test session, run full cleanup:

SKILL_DIR="<path-to-this-skill>"

# Kill all processes and remove test data
$SKILL_DIR/scripts/cleanup.sh

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
