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.

SkillSpector: 3 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00104 | $0.03512 |
| Opus 5 | $0.00052 | $0.01756 |
| Sonnet 5 | $0.00021 | $0.00702 |
| Haiku 4.5 | $0.00010 | $0.00351 |
Grade A, and why
cloudflare-images scanned grade A with 1 finding 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.

Cloudflare Images
Status: Production Ready ✅ | Version: 3.0.0 | Last Verified: 2025-12-27
What Is Cloudflare Images?
Two powerful features:
- Images API: Upload, store, serve images globally
- Image Transformations: Resize/optimize ANY image
Key benefits:
- Global CDN delivery
- Automatic WebP/AVIF conversion
- Up to 100 variants
- Direct creator upload (no API keys in frontend)
- Signed URLs for private images
- Transform any image via URL or Workers
Quick Start (5 Minutes)
1. Enable Cloudflare Images
Dashboard → Images → Enable
Get your Account ID and create API token (Cloudflare Images: Edit permission)
2. Upload Image
curl --request POST \
--url https://api.cloudflare.com/client/v4/accounts/<ACCOUNT_ID>/images/v1 \
--header 'Authorization: Bearer <API_TOKEN>' \
--header 'Content-Type: multipart/form-data' \
--form 'file=@./image.jpg'
CRITICAL: Use multipart/form-data, not JSON
3. Serve Image
<img src="https://imagedelivery.net/<ACCOUNT_HASH>/<IMAGE_ID>/public" />
4. Enable Transformations
Dashboard → Images → Transformations → Enable for zone
Transform ANY image:
<img src="/cdn-cgi/image/width=800,quality=85/uploads/photo.jpg" />
5. Transform via Workers
export default {
async fetch(request: Request): Promise<Response> {
return fetch("https://example.com/image.jpg", {
cf: {
image: {
width: 800,
quality: 85,
format: "auto" // WebP/AVIF
}
}
});
}
};

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.
- 5d ago First seen · 459 lines · 104 tokens per session scan A 1e9299f9362e
cloudflare-images is a skill published in the GitHub repository secondsky/claude-skills (216 stars, last pushed 2d ago), licensed MIT. It adds 104 tokens to every session and 3,512 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
Other skills, from other repositories
make-bot-ui
Use when a human invokes this skill to build a webhook UI that wakes a bot. Not for unpreviewed or unapproved credential, host, Tailscale, deployment, remote, paid, or irreversible changes.
remember
Record why something is the way it is — a decision and its reasoning, a lesson that cost time, or a standing constraint. Use when the reasoning behind a choice would be expensive to reconstruct later.
bootstrap
Set up chamnan in this repository for the first time — build the architecture index, measure how well the code describes itself, fill in missing file comments, and record a baseline. Run once per repo.
resume
Write down where this stretch of work stopped, so the next session continues instead of restarting. Use at the end of a working session, or when handing the repository to someone else.
milestone
Record a change that reshaped the repository — what moved, why it was worth doing, and which areas it touched. Use after a migration, a rewrite, or a decision that changed how part of the system works.
capture
Write down a procedure worth keeping — a multi-step process, a trap that cost real time, or something that has now come up three times. Use it the moment you finish such a task, while the details are still exact.
