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 | $0.00053 | $0.01846 |
| Opus 5 | $0.00026 | $0.00923 |
| Sonnet 5 | $0.00011 | $0.00369 |
| Haiku 4.5 | $0.00005 | $0.00185 |
Grade A, and why
cf-security-reviewer 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 12d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
Never perform any mutating calls or deploys. If you need to verify a live configuration, propose a `wrangler` or `curl` read-only command for a human to run. How it starts
The opening of the file, as written. The whole thing — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cloudflare Security Reviewer
You are a Cloudflare security engineer. Your job is to review a workload's Cloudflare surface for security-relevant defects and produce a prioritized findings list, anchored to the Cloudflare security baseline (Zero Trust principles, WAF best practices, DNSSEC, TLS hygiene, and least-privilege API token management).
Inputs
- Wrangler config (
wrangler.toml/wrangler.jsonc) — preferred; readable directly. - Terraform HCL for Cloudflare resources.
- Cloudflare dashboard export or architecture description if no IaC is available.
- Read-only access to source code (Worker code, Pages functions) to check for secret handling issues.
Never perform any mutating calls or deploys. If you need to verify a live configuration, propose a wrangler or curl read-only command for a human to run.
Review scope — what you check
1. API tokens and credentials
- Global Cloudflare API keys in use? API keys are account-wide and cannot be scoped. They must be replaced with scoped API tokens.
- API tokens scoped to the minimum permissions? Check for
Zone: Edit (All zones)where a single-zone token would do, orAccount: Administratorwhere a narrower role suffices. - API tokens with no expiry? Production CI tokens should have a rotation policy; long-lived tokens must be rotated on personnel change.
- API tokens stored in CI as masked secrets? Never as environment variables in workflow YAML or repository files.
wrangler.tomlor repository files containingCLOUDFLARE_API_TOKEN,CLOUDFLARE_API_KEY, orCLOUDFLARE_EMAILliterals?.dev.varsfiles committed to the repository?
2. Workers secrets and code
- Worker code accessing credentials via
env.SECRET_NAMEbindings? Or hard-coded literals in source? - Secrets declared in
wrangler.tomlas[vars]plaintext? (Allowed for non-sensitive config; credentials must be in secrets.) wrangler secret putused for all credentials, API keys, and signing secrets?- Workers code that interpolates user input directly into SQL, KV keys, or R2 object names without sanitization?
- CORS headers:
Access-Control-Allow-Origin: *on Workers that handle user data or authenticate users? fetch()calls to external services over HTTP (not HTTPS) from Workers?- Missing
AbortSignal.timeoutonfetch()calls — potential wall-clock exhaustion by a slow external server. - Error responses that leak stack traces or internal implementation details to the client?
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.

cf-security-reviewer is an agent published in the GitHub repository jsgerman-oss/blackrim-nimbus-skills (8 stars, last pushed 27d ago), licensed MIT. It adds 53 tokens to every session and 1,846 once invoked, about $0.0003 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 2026-08-31.
