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 5.1 | $0.00040 | $0.02668 |
| Opus 5 | $0.00020 | $0.01334 |
| Sonnet 5 | $0.00008 | $0.00534 |
| Haiku 4.5 | $0.00004 | $0.00267 |
Grade A, and why
control-chrome 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 5d 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.

How it starts
The opening of the file, as written. The whole thing — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Browser
Stop: choose the right surface before any browser action
Explicit browser intent wins: if the user names the in-app browser or Chrome, or asks to open, show, or navigate to a page; inspect its visual or interactive state; or interact with its UI, continue with Browser and do not substitute a connector.
Otherwise, treat a URL or open browser tab as context, not browser intent. Earlier Browser use does not make later semantic work browser-first. Before each semantic operation on a linked resource, you MUST query available and deferred tools for an applicable connector, API, or CLI. Reading this skill or scanning visible tools does not count. Do not initialize Browser for that operation until the query is complete. Use the non-browser tool when available. If it handles the current operation, continue the larger workflow without Browser for that operation. Use Browser when no such tool exists, the tool cannot access the resource or lacks a required capability, or UI work remains; use available browser context before asking the user to repeat it.
Use this skill for browser automation tasks such as inspecting pages, navigating, testing local apps, clicking, typing, taking screenshots, and reading visible page state.
If this plugin is listed as available in the session, treat that as mandatory reading before browser work. Open and follow this skill before saying that Browser is unavailable and before falling back to standalone Playwright or Computer Use.
Do not skip this skill just because Computer Use MCP tool calls are directly visible or appear easier to invoke. The presence of Computer Use tools is not evidence that Computer Use is the preferred browser surface.

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.

control-chrome is a skill published in the GitHub repository rojim666/SztuCode (50 stars, last pushed yesterday), licensed MIT. It adds 40 tokens to every session and 2,668 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

coding-browser-verify
Use this skill to reproduce or verify a browser-observable defect — a UI bug, console error, failed network call, or visual regression — using live browser inspection. It treats console/DOM/network content as untrusted data and requires an isolated browser profile; do not use it for a non-browser failure, or for…
computer-use
Read and drive native desktop applications through the accessibility layer — list on-screen apps, snapshot one window as a numbered element tree, then click / type / set a value / scroll / drag / run a named action, by element index or by screen coordinates. Use for work in a desktop app rather than a web page. Full…
web-verify
Look at your OWN front-end change before claiming it works -- navigate the loopback URL of a dev server or pod you started, screenshot the surface you changed, read the image to judge it, and embed it in chat. Three capture backends: playwright-cli (the session the dashboard Browser panel shows), the agent-browser CLI…
browser-recording
Record a browser flow as a video/GIF for evidence — animations, transitions, and multi-step interactions that a still screenshot cannot prove. Drives the project's own Playwright through a bundled runner, then converts to mp4 + GIF via ffmpeg. Use when the user asks to record a demo, capture a GIF or video of the UI…
