Adding a Plugin

Each plugin lives in its own directory under plugins/:

plugins/your-plugin/
├── .claude-plugin/
│   └── plugin.json              # Required: name, description, author
├── commands/                    # Optional: slash commands
├── agents/                      # Optional: agent definitions
├── skills/                      # Optional: skill definitions
└── README.md                    # Plugin documentation

Then add an entry in .claude-plugin/marketplace.json:

{
    "name": "your-plugin",
    "description": "What it does",
    "source": "./plugins/your-plugin",
    "category": "productivity"
}

Browser QA Testing

The ac plugin includes /ac:browser-qa — a browser-based QA testing command with 4 modes:

Mode	Trigger	Description
Ad-hoc	URL or instructions	Navigate and test freeform
Bug repro	--bug <path>	Reproduce bugs from a document
Plan verify	--plan <path>	Verify plan acceptance criteria
Re-check	--recheck	Re-run previously failed tests

Evidence Persistence

Test evidence is saved by default to .ac/qa/ in the project directory:

.ac/qa/{testName}/
  {YYYYMMDD}-{HHmmss}-{pagePath}.png    # Screenshots (on FAIL)
  {YYYYMMDD}-{HHmmss}-{pagePath}.html   # Page HTML snapshots
  {YYYYMMDD}-{HHmmss}-{pagePath}.json   # Console + network errors
  report.md                              # Latest report

Disable with --no-evidence flag.

Required: Playwright CLI

npm install -g @playwright/cli@latest
