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.

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 5.1 | $0.00000 | $0.01710 |
| Opus 5.5 | $0.00000 | $0.00684 |
| Sonnet 5.5 | $0.00000 | $0.00342 |
| Haiku 4.5 | $0.00000 | $0.00171 |
Grade A, and why
iframe 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 1mo 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 — 265 lines — stays where its author put it; the contents beside it link to each section on GitHub.
iFrame Embed Mode
CRITICAL: This mode is for widgets embedded as iframes in external web pages. This is NOT a native window. This is NOT Jupyter. The widget is sandboxed.
What iFrame Mode IS
You're creating widgets to be embedded as iframes in external pages:
- Widget served at a URL:
http://host:port/widget/{widget_id} - Embedded via
<iframe src="...">in parent page - Sandboxed execution - isolated from parent
- Cross-origin restrictions apply
What iFrame Mode is NOT
❌ NOT a native window - No OS integration, no native dialogs ❌ NOT Jupyter - No kernel, no notebook context ❌ NOT the main page - You're embedded, constrained by parent

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.

iframe is a skill published in the GitHub repository deeleeramone/PyWry (98 stars, last pushed 4d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,710 tokens. 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.

browser-use
Drive agentglass's built-in browser — the one already signed in to the sites this project uses. Use when a task needs a page behind a login (a dashboard, a ticket, a staging app), when a URL fetched with curl comes back signed out or JavaScript-rendered, or when the user asks you to look at, click through, or…
wfdash
Serve wayfinder maps held in GitHub Issues as a local browser dashboard — one map drawn as a dependency DAG, plus an overview of every map across every repo. Use when the user asks what to work on next, wants to see a map's shape or frontier, wants to read a resolved ticket's decision, or types /wfdash. Also use for…
clickjacking-ui-redressing
Identify and exploit Clickjacking (UI Redressing) vulnerabilities where a malicious website iframes a target application, tricking victims into performing unintended actions (e.g., transferring funds, deleting accounts, or granting permissions) via hidden layers.
fleet-verify
Use after a UI or user-visible change and before you claim it works — it spawns ONE CCC verification lane that drives a real browser (gstack browse, or CCC's puppeteer snapshot as fallback) against the running app, checks the specific thing you changed, and reports a visual/behavioral verdict with a screenshot.…
debug-optimize-lcp
Guides debugging and optimizing Largest Contentful Paint (LCP) using Chrome DevTools MCP tools. Use this skill whenever the user asks about LCP performance, slow page loads, Core Web Vitals optimization, or wants to understand why their page's main content takes too long to appear. Also use when the user mentions…
pinchtab-mcp
Use this skill when a task requires browser automation through PinchTab's MCP server connected to a remote browser instance. Covers navigation, element interaction, data extraction, form filling, multi-step flows, and session management via MCP tools.
