Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00038 | $0.00929 |
| Opus 5 | $0.00019 | $0.00464 |
| Sonnet 5 | $0.00008 | $0.00186 |
| Haiku 4.5 | $0.00004 | $0.00093 |
Grade A, and why
chrome-devtools scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Chrome DevTools Agent
Overview
A specialized skill for controlling and inspecting a live Chrome browser. This skill leverages the chrome-devtools MCP server to perform a wide range of browser-related tasks, from simple navigation to complex performance profiling.
When to Use
Use this skill when:
- Browser Automation: Navigating pages, clicking elements, filling forms, and handling dialogs.
- Visual Inspection: Taking screenshots or text snapshots of web pages.
- Debugging: Inspecting console messages, evaluating JavaScript in the page context, and analyzing network requests.
- Performance Analysis: Recording and analyzing performance traces to identify bottlenecks and Core Web Vital issues.
- Emulation: Resizing the viewport or emulating network/CPU conditions.
Tool Categories
1. Navigation & Page Management
new_page: Open a new tab/page.navigate_page: Go to a specific URL, reload, or navigate history.select_page: Switch context between open pages.list_pages: See all open pages and their IDs.close_page: Close a specific page.wait_for: Wait for specific text to appear on the page.
2. Input & Interaction
click: Click on an element (useuidfrom snapshot).fill/fill_form: Type text into inputs or fill multiple fields at once.hover: Move the mouse over an element.press_key: Send keyboard shortcuts or special keys (e.g., "Enter", "Control+C").drag: Drag and drop elements.handle_dialog: Accept or dismiss browser alerts/prompts.upload_file: Upload a file through a file input.
3. Debugging & Inspection
take_snapshot: Get a text-based accessibility tree (best for identifying elements).take_screenshot: Capture a visual representation of the page or a specific element.list_console_messages/get_console_message: Inspect the page's console output.evaluate_script: Run custom JavaScript in the page context.list_network_requests/get_network_request: Analyze network traffic and request details.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
