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.

[](https://agentmods.dev/skills/binary16labs/prime-silo/screenshots)What it costs to keep this loaded
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 | $0.00014 | $0.00495 |
| Opus 5 | $0.00007 | $0.00247 |
| Sonnet 5 | $0.00003 | $0.00099 |
| Haiku 4.5 | $0.00001 | $0.00049 |
Grade A, and why
Screenshots 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.
This is a copy
100% identical to Screenshots — 22 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Use this skill when the user wants a browser screenshot.
load helper
- Import
/mod/_core/skillset/ext/skills/screenshots/screenshots.js - The helper lazy-loads
html2canvasfor you - Prefer these exports instead of pasting the whole capture script inline
- If you need lower-level control, inspect
/mod/_core/skillset/ext/skills/screenshots/screenshots.jsand pass customhtml2canvasOptions
helpers
await import("/mod/_core/skillset/ext/skills/screenshots/screenshots.js")takeScreenshot({ target?, filename?, type?, quality?, html2canvasOptions? })->{ canvas, blob, width, height, type, filename }screenshotBase64(options)->{ base64, width, height, type, filename }screenshotDownload("name.png", options?)-> downloads and returns{ downloaded: true, filename, width, height, type }
target
- Omit
targetfor a full-pagedocument.bodyscreenshot targetmay be a CSS selector string or a DOM element- Default file name is
page-content.png
guidance
- Prefer
screenshotDownload(...)when the user wants an actual image file - Use
screenshotBase64(...)only when JavaScript needs inline image data, because the return value is large
examples Taking a low-level screenshot result _javascript const screenshots = await import("/mod/_core/skillset/ext/skills/screenshots/screenshots.js") return await screenshots.takeScreenshot()
Downloading a full-page screenshot _javascript const screenshots = await import("/mod/_core/skillset/ext/skills/screenshots/screenshots.js") return await screenshots.screenshotDownload("page-content.png")
Capturing a specific panel _javascript const screenshots = await import("/mod/_core/skillset/ext/skills/screenshots/screenshots.js") return await screenshots.screenshotDownload("panel.png", { target: "[data-panel]" })
Getting base64 image data _javascript const screenshots = await import("/mod/_core/skillset/ext/skills/screenshots/screenshots.js") return await screenshots.screenshotBase64()
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

Screenshots is a skill published in the GitHub repository binary16labs/prime-silo (5 stars, last pushed 10d ago), licensed MIT. It adds 14 tokens to every session and 495 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to Screenshots, differing in 22 lines, and is treated as a copy.

xh
Use when the agent or user needs to make an HTTP request from the shell - GET a URL, POST JSON to an API, check a webhook with auth, test a REST endpoint, fetch and inspect headers, or upload a file.
dingtalk_channel_connect
Use a headed browser to automatically complete DingTalk channel integration for QwenPaw. Applicable when the user mentions DingTalk, developer console, Client ID, Client Secret, bot, Stream mode, binding or configuring a channel. Supports pausing when a login page is detected and resuming after the user logs in.
dingtalk_channel_connect
使用可视浏览器自动完成 QwenPaw 的钉钉频道接入。适用于用户提到钉钉、DingTalk、开发者后台、Client ID、Client Secret、机器人、Stream 模式、绑定或配置 channel 的场景；支持遇到登录页时暂停，等待用户登录后继续。.
browser_cdp
Use this skill when the user explicitly wants to connect to a running Chrome browser, scan local CDP ports, specify a cdpport, or share a single browser across multiple agents/tools. By default browser opens no debugging port; pass an explicit cdpport only when the user wants another local tool to attach.
browser_cdp
当用户明确希望连接到已运行的 Chrome 浏览器、扫描本地 CDP 端口、显式指定 cdpport，或让多个 agent / 工具共享同一个浏览器时，使用本 skill。browser 默认不开放调试端口；仅当用户明确希望其他本地工具附加时才显式传入 cdpport。.
browser_visible
当用户需要控制 browser 的浏览器启动方式时，使用本 skill。browser 默认由 Playwright 直接管理、不开放调试端口（需让其他本地工具附加时显式传 cdpport）；headed 控制是否显示窗口，privatemode 保留用于兼容、不再改变默认行为，browserargs 传入额外的 Chromium 启动参数，executablepath 指定自定义浏览器可执行文件路径。.
