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 | $0.00055 | $0.01061 |
| Opus 5.5 | $0.00022 | $0.00424 |
| Sonnet 5.5 | $0.00011 | $0.00212 |
| Haiku 4.5 | $0.00006 | $0.00106 |
Grade A, and why
explain 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.
How it starts
The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Explain CE.SDK
Topic: $ARGUMENTS
Covers Web (React, Vue.js, Svelte, Angular, Electron, Vanilla JavaScript, Node.js, Nuxt.js, Next.js, SvelteKit); Flutter (Dart) on iOS and Android; React Native (TypeScript) on iOS and Android; Swift on iOS, macOS, and Mac Catalyst; Kotlin and Jetpack Compose on Android.
Platform Detection
Detect the platform from the project files, then read the matching reference folder.
| Project files | Platform | Reference folder |
|---|---|---|
pubspec.yaml (its android/ and ios/ folders belong to the Flutter app) |
Flutter (Dart; native editor on iOS and Android) | references/flutter/ |
react-native in package.json dependencies (its android/ and ios/ folders belong to the React Native app) |
React Native (TypeScript; native editor on iOS and Android) | references/react-native/ |
Package.swift, *.xcodeproj, or *.xcworkspace |
Swift (iOS, macOS, Mac Catalyst) | references/swift/ |
build.gradle, build.gradle.kts, or settings.gradle* |
Android (Kotlin, Jetpack Compose) | references/android/ |
package.json |
Web — pick the framework from its dependencies (table below) | references/web/ |
Match the rows in the order listed. A Flutter or React Native project also
holds android/ and ios/ folders, and a React Native project lists
react in package.json; those files belong to the wrapper app, so its row
wins over the Swift, Android, and Web rows.
Web framework from package.json dependencies
What ships with it
6 files 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.

explain is a skill published in the GitHub repository imgly/agent-skills (9 stars, last pushed today), licensed MIT. It adds 55 tokens to every session and 1,061 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-31.
