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 | $0.00014 | $0.00263 |
| Opus 5 | $0.00007 | $0.00131 |
| Sonnet 5 | $0.00003 | $0.00053 |
| Haiku 4.5 | $0.00001 | $0.00026 |
Grade A, and why
security-review 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 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.
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.
What it actually says
Security Review Process
Review Checklist
On every review, systematically check for:
- Injection flaws — SQL, NoSQL, OS command, LDAP injection
- Broken authentication — weak session management, credential exposure
- Sensitive data exposure — plaintext storage, weak crypto, missing TLS
- Broken access control — IDOR, privilege escalation, missing authorization
- Security misconfiguration — default credentials, verbose errors, open CORS
- Cross-Site Scripting — reflected, stored, DOM-based XSS
- Insecure deserialization — untrusted data deserialization
- Vulnerable components — outdated dependencies with known CVEs
- Hardcoded secrets — API keys, passwords, tokens, private keys
Review Steps
- Read the diff completely before making any comments
- Check each changed file against the checklist above
- For each finding: identify CWE, assess severity, write remediation
- Review dependency changes against vulnerability databases
- Verify error handling doesn't leak internal details
- Summarize findings by severity (Critical → Low)
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.

security-review is a skill published in the GitHub repository 0xranx/agentbrief (45 stars, last pushed 5mo ago), licensed MIT. It adds 14 tokens to every session and 263 once invoked, about $0.0001 per session on Opus 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 2026-08-30.
