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 | $0.00024 | $0.00674 |
| Opus 5 | $0.00012 | $0.00337 |
| Sonnet 5 | $0.00005 | $0.00135 |
| Haiku 4.5 | $0.00002 | $0.00067 |
Grade A, and why
cloudflare-agents 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 4d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Cloudflare Agents
Last Updated: 2025-11-21
Quick Start
export default {
async fetch(request, env, ctx) {
const agent = {
tools: [
{ name: 'getTodo', handler: async ({id}) => ({id, title: 'Task'}) }
],
async run(input) {
return await processWithLLM(input, this.tools);
}
};
return Response.json(await agent.run(await request.text()));
}
};
Core Features
- Tool Integration: Register and execute tools
- LLM Providers: OpenAI, Anthropic, Google Gemini
- MCP Protocol: Model Context Protocol support
- Cloudflare Bindings: D1, KV, R2, Durable Objects
Agent Pattern
const agent = {
tools: [...],
systemPrompt: 'You are a helpful assistant',
model: 'gpt-4o',
async run(input) {
// Process with LLM
}
};

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.
- 4d ago First seen · 85 lines · 24 tokens per session scan A 3e73ecc57a89
cloudflare-agents is a skill published in the GitHub repository secondsky/claude-skills (215 stars, last pushed today), licensed MIT. It adds 24 tokens to every session and 674 once invoked, about $0.0001 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
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.
promote
Turn a scratch script into a permanent tool this repo keeps. Use when a check, report, or analysis has proved worth running more than once.
