What this skill does


# Playwright Bowser

## Purpose

Automate browsers using `playwright-cli` — a token-efficient CLI for Playwright. Runs headless by default, supports parallel sessions via named sessions (`-s=`), and doesn't load tool schemas into context.

## Key Details

- **Headless by default** — pass `--headed` to `open` to see the browser
- **Parallel sessions** — use `-s=<name>` to run multiple independent browser instances
- **Persistent profiles** — cookies and storage state preserved between calls
- **Token-efficient** — CLI-based, no accessibility trees or tool schemas in context
- **Vision mode** (opt-in) — set `PLAYWRIGHT_MCP_CAPS=vision` to receive screenshots as image responses in context instead of just saving to disk

## Sessions

**Always use a named session.** Derive a short, descriptive kebab-case name from the user's prompt. This gives each task a persistent browser profile (cookies, localStorage, history) that accumulates across calls.

```bash
# Derive session name from prompt context:
# "test the checkout flow on mystore.com" → -s=mystore-checkout
# "scrape pricing from competitor.com"    → -s=competitor-pricing
# "UI test the login page"               → -s=login-ui-test

playwright-cli -s=mystore-checkout open https://mystore.com --persistent
playwright-cli -s=mystore-checkout snapshot
playwright-cli -s=mystore-checkout click e12
```

Managing sessions:
```bash
playwright-cli list                                     # list all sessions
playwright-cli close-all                                # close all sessions
playwright-cli -s=<name> close                          # close specific session
playwright-cli -s=<name> delete-data                    # wipe session profile
```

## Quick Reference

```
Core:       open [url], goto <url>, click <ref>, fill <ref> <text>, type <text>, snapshot, screenshot [ref], close
Navigate:   go-back, go-forward, reload
Keyboard:   press <key>, keydown <key>, keyup <key>
Mouse:      mousemove <x> <y>, mousedown, mouseup, mousewheel <dx> <dy>
Tabs:       tab-list, tab-new [url], tab-close [index], tab-select <index>
Save:       screenshot [ref], pdf, screenshot --filename=f
Storage:    state-save, state-load, cookie-*, localstorage-*, sessionstorage-*
Network:    route <pattern>, route-list, unroute, network
DevTools:   console, run-code <code>, tracing-start/stop, video-start/stop
Sessions:   -s=<name> <cmd>, list, close-all, kill-all
Config:     open --headed, open --browser=chrome, resize <w> <h>
```

## Workflow

1. Derive a session name from the user's prompt and open with `--persistent` to preserve cookies/state. Always set the viewport via env var at launch:
```bash
PLAYWRIGHT_MCP_VIEWPORT_SIZE=1440x900 playwright-cli -s=<session-name> open <url> --persistent
# or headed:
PLAYWRIGHT_MCP_VIEWPORT_SIZE=1440x900 playwright-cli -s=<session-name> open <url> --persistent --headed
# or with vision (screenshots returned as image responses in context):
PLAYWRIGHT_MCP_VIEWPORT_SIZE=1440x900 PLAYWRIGHT_MCP_CAPS=vision playwright-cli -s=<session-name> open <url> --persistent
```

3. Get element references via snapshot:
```bash
playwright-cli snapshot
```

4. Interact using refs from snapshot:
```bash
playwright-cli click <ref>
playwright-cli fill <ref> "text"
playwright-cli type "text"
playwright-cli press Enter
```

5. Capture results:
```bash
playwright-cli screenshot
playwright-cli screenshot --filename=output.png
```

6. **Always close the session when done.** This is not optional — close the named session after finishing your task:
```bash
playwright-cli -s=<session-name> close
```

## Configuration

If a `playwright-cli.json` exists in the working directory, use it automatically. If the user provides a path to a config file, use `--config path/to/config.json`. Otherwise, skip configuration — the env var and CLI defaults are sufficient.

```json
{
  "browser": {
    "browserName": "chromium",
    "launchOptions": {
      "headless": true,
      "args": [
        "--disable-save-password-bubble",
        "--disable-password-manager-reauthentication",
        "--password-store=basic"
      ]
    },
    "contextOptions": { "viewport": { "width": 1440, "height": 900 } }
  },
  "outputDir": "./screenshots"
}
```

The `args` array disables Chrome's password save prompts that can interfere with automation.

## Full Help

Run `playwright-cli --help` or `playwright-cli --help <command>` for detailed command usage.

contribute

Included

Local-only OSS contribution command center. Auto-refreshes the user's in-flight PR and issue state on invoke so conversations start with full context — no need to brief Claude on what's in flight. Helps the user find issues to contribute to on GitHub, builds per-repo dossiers of what each upstream expects (CLA, DCO, branch convention, AI policy, draft-first, review bots, issue templates), runs deterministic gates before any external action so AI-assisted contributions don't reach maintainers as slop. State is markdown-only: candidate files at ~/.contribute-system/candidates/, repo dossiers at ~/.contribute-system/research/, append-only event log at ~/.contribute-system/log.jsonl. No database, no cloud calls. Use when the user asks about their PRs / issues / contributions, wants to find new work to take on, claim an issue, build/refresh a repo's dossier, or draft a Design Issue or PR. Trigger with "/contribute", "what's my PR status", "find a contribution", "claim issue X", "draft a Design Issue for Y", "refresh dossier for Z".

architectural-analysis

Included

User-triggered deep architectural analysis of a codebase or scoped subtree across eight modes — information architecture, data flow, integration points, UI surfaces, interaction patterns, data model, control flow, and failure modes. This skill should be used when the user asks to "diagram this codebase," "map the architecture," "show the data flow," "give me an ERD," "trace control flow," "find the integration points," "verify the layout pattern," "audit the UX architecture," or any similar request whose primary deliverable is mermaid diagrams plus cited reports under docs/architecture/. Dispatches haiku/sonnet sub-agents in parallel for per-mode exploration, then verifies every citation mechanically before any node lands in a diagram. Not for one-off prose explanations of code (use code-explanation) or for high-level system design from scratch (use system-design).
