# Dev Tools Skill
## Overview
Use the Chrome DevTools MCP server to diagnose and fix frontend issues by observing the live page, gathering evidence (console, network, performance), and proposing targeted code changes.
## Quick Start
1. Confirm the user wants DevTools used (or they already asked).
2. Open the target page, then take an a11y snapshot.
3. Triage via console + network + quick DOM inspection.
4. Choose the appropriate workflow below and follow it end-to-end.
5. Summarize findings + propose the smallest safe fix.
## Workflow Decision Tree
- **UI/interaction bug** (layout, hover/click, missing text): use *UI/Interaction Workflow*.
- **Performance/lag** (slow load, jank, long TTI): use *Performance Workflow*.
- **API/network issue** (failed fetch, wrong data): use *Network Workflow*.
- **Runtime error** (crash, blank screen, stack trace): use *Console/Error Workflow*.
## Core Workflows
### 1) Triage (always first)
- Capture state: `list_pages` → `select_page` → `take_snapshot`.
- Scan for visible errors (missing sections, broken layout) in snapshot text.
- Check console messages (`list_console_messages`, then `get_console_message` for details).
- Check network requests (`list_network_requests`, then `get_network_request` for errors/slow calls).
- Form a hypothesis and select a workflow below.
### 2) UI/Interaction Workflow
- Use `take_snapshot` to locate the target element; if unclear, `take_screenshot`.
- Inspect element text/attributes via `evaluate_script` (r
