Token cost

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.

Security

Grade A, and why

cloudflare-skill AGENTS.md 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.

# CORRECT

jj new
jj commit -m "msg"

# WRONG - do not use
git status  # .jj/ present = use jj

Reference File Structure

Every product follows 5-file pattern:

  • README.md — Overview, when to use
  • api.md — Runtime API reference
  • configuration.md — wrangler.toml + binding setup
  • patterns.md — Usage patterns
  • gotchas.md — Pitfalls, limitations

YAML Frontmatter

SKILL.md files use frontmatter for machine parsing:

---
name: product-name
description: Brief description
references:
  - related-product
---

ANTI-PATTERNS

SQL Injection (D1)

// NEVER - string interpolation
const result = await db.prepare(`SELECT * FROM users WHERE id = ${id}`).all();

// ALWAYS - prepared statements with bind()
const result = await db.prepare("SELECT * FROM users WHERE id = ?").bind(id).all();

Secrets Management

# NEVER commit .dev.vars (contains secrets)
# NEVER hardcode secrets in code

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.
