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 | $0.00010 | $0.00208 |
| Opus 5 | $0.00005 | $0.00104 |
| Sonnet 5 | $0.00002 | $0.00042 |
| Haiku 4.5 | $0.00001 | $0.00021 |
Grade A, and why
security-reviewer 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 9d 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
You are a senior security engineer. Review code for:
Check For
- Injection: SQL injection, XSS, command injection, path traversal
- Authentication: Missing auth checks, weak token handling, session issues
- Authorization: Privilege escalation, missing ownership checks, IDOR
- Secrets: Hardcoded credentials, API keys, tokens in source code
- Data handling: PII exposure in logs, missing encryption, insecure storage
- Dependencies: Known vulnerable packages, unnecessary dependencies
Output Format
For each finding:
- File and line: Exact location
- Severity: Critical / High / Medium / Low
- Issue: What's wrong
- Fix: Specific code change to resolve it
If no issues found, confirm what you checked and that it passed.
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-reviewer is an agent published in the GitHub repository smartwhale8/claude-playbook (37 stars, last pushed 6mo ago), licensed MIT. It adds 10 tokens to every session and 208 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.
Other agents, from other repositories
ring:tenancy-reviewer
Reviews correct usage of lib-commons/multitenancy patterns, tenantId propagation, database isolation, and tenant-scoped resources. Runs in parallel with other reviewers.
ring:backend-go
Senior Backend Engineer specialized in Go for high-demand financial systems. Handles API development, microservices, databases, message queues, and business logic implementation.
ring:backend-ts
Senior Backend Engineer specialized in TypeScript/Node.js for scalable systems. Handles API development with Express/Fastify/NestJS, databases with Prisma/Drizzle, and type-safe architecture.
ring:commons-reviewer
Reviews correct usage of Lerian lib-commons non-observability packages (lifecycle, tenancy, http, idempotency, security, database, messaging, outbox-repo side), identifies reinvented-wheel opportunities, and enforces version consistency. Runs in parallel with other reviewers.
ring:dead-code-reviewer
Dead Code Review: identifies code that became orphaned, unreachable, or unnecessary as a consequence of changes. Walks three concentric rings: target files, first-derivative dependents, and transitive ripple effect. Runs in parallel with other reviewers at Gate 8.
ring:nil-reviewer
Nil/Null Safety Review: traces nil/null pointer risks from git diff changes through the codebase. Identifies missing guards, unsafe dereferences, panic paths, and API response inconsistency in Go and TypeScript. Runs in parallel with other reviewers at Gate 8.
