description: Use when an agent needs the visible local Grasp browser runtime for multi-step web tasks or public-web extraction through one interface: confirm the runtime instance, enter URLs, inspect/extract/share page content, switch visible tabs, interact with live pages, fill forms, operate authenticated workspaces, capture screenshots, and recover through handoff after login or CAPTCHA checkpoints.

Why use this skill
skill is most useful when you want an agent workflow that is more structured than an ad-hoc prompt. Instead of restating the same expectations every time, a dedicated SKILL.md file gives the assistant a repeatable brief. In this case, the core value is clarity: the repo already frames the workflow around utility skills tasks, and the skill source gives you a portable starting point you can evaluate, adapt, and reuse. The inferred platform for this skill is Generic Skills, which helps you judge whether it is likely to feel native in your current agent ecosystem or whether it is better treated as a general reference.
That matters because AI assistants are better when the operating context is explicit. A good skill turns hidden team expectations into visible instructions. It can name preferred tools, describe failure modes, define what “done” looks like, and reduce the amount of corrective prompting you need after the first draft. For developers exploring the wider SKILL.md ecosystem, this page helps answer the practical question: is this skill specific and maintained enough to be worth trying?
How to evaluate and use it
Start with the source repo and the preview below. The preview tells you whether the instructions are actionable or just aspirational. Strong skills usually describe triggers, recommended tools, steps, and known pitfalls. Weak skills tend to stay generic. This one lives in Yuzc-001/grasp, which gives you a concrete repo context, update history, and direct ownership trail.
Once you confirm the scope looks right, test it on a small task before making it part of a larger workflow. If it improves consistency, keep it. If it is too broad, outdated, or conflicts with your own process, treat it as a reference rather than a drop-in rule. That is the healthiest way to use directory-discovered skills: not as magic plugins, but as reusable operational knowledge that still deserves judgment.

Use MCP tools for page actions instead of recreating interactions in shell scripts. - Start with `get_status`. Before page-changing actions, prefer `confirm_runtime_instance(display="windowed")` or confirm the mode you actually expect. - If a tool returns `INSTANCE_CONFIRMATION_REQUIRED`, confirm the instance and retry the same action. - For first arrival to a URL, prefer `entry(url, intent)`. Use `navigate(url)` only when you intentionally want to move the current page directly. - Prefer the high-level surfaces first: runtime loop, form tools, and workspace tools. Drop to hint map, tabs, cookies, dialogs, or `evaluate` only when the higher-leve ...
