How It Works

These plugins use Claude Code's native hook system to optimize expensive operations. No API key needed — uses claude CLI with your existing Claude Code subscription auth.

playwright-optimizer

Playwright MCP sends massive YAML snapshots (10K-60K+ chars) for every browser interaction. This plugin intercepts them via PostToolUse hook, summarizes with Claude Haiku via claude -p --model haiku, and passes a compact summary to your primary model.

Playwright MCP → 60,000 char YAML snapshot
    → PostToolUse hook triggers
    → claude -p --model haiku (internal auth, no API key)
    → ~4,000 char summary (all ref= values preserved)
    → Opus receives compact summary only

Tested results:

Metric	Before	After	Change
browser_navigate	37,983 chars	1,922 chars	-94%
browser_snapshot	37,897 chars	1,435 chars	-96%

Requirements

• Claude Code CLI (claude) installed and authenticated
• jq installed (pre-installed on most systems)
• Playwright MCP server configured
