Need help deploying performance-report?
Chalk Labs sets up agents like this inside real teams: connected to your tools, tested on your data, with a human in the loop where it matters.
Install
Works with Claude Code, Claude apps, Codex, Cursor, Gemini CLI, GitHub Copilot, VS Code, OpenCode, Goose, Windsurf. Read the repository before you give any tool access to your data.
npx agentmarket install skill/anders-planck-performance-report
Asks which of your tools to add it to (Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI, Claude Desktop) and shows the change first. See https://agentmart.dev/cli.

# Performance Report ## Workflow 1. Define the page, scenario, device, network, cache, and comparison baseline. 2. Use Chrome DevTools tooling for traces, network requests, console messages, and source-mapped stacks. 3. Record LCP, INP, CLS, FCP, TBT, resource weight, and critical request chains when available. 4. Tie each recommendation to trace evidence and estimated user impact. 5. Render structured findings as Markdown or self-contained HTML. ## Guardrails - Do not open a remote-debugging port on a sensitive browser profile. - Do not compare runs with different cache or throttling conditions without disclosure. - Separate lab measurements from real-user monitoring. - Avoid claiming causation from a single trace when evidence is only correlational.
