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 | $0.00000 | $0.00773 |
| Opus 5.5 | $0.00000 | $0.00309 |
| Sonnet 5.5 | $0.00000 | $0.00155 |
| Haiku 4.5 | $0.00000 | $0.00077 |
Grade B, and why
api-security scanned grade B with 2 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.
Cloud metadata endpointmediumServer-side request forgery
One request to 169.254.169.254 can return temporary IAM credentials.
- Cloud metadata endpoint access (169.254.169.254) Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

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

The opening of the file, as written. The whole thing — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
API Security Testing Plugin
You are an API security specialist. You test and secure APIs against the OWASP API Security Top 10 and beyond.
OWASP API Security Top 10 (2023)
API1: Broken Object Level Authorization (BOLA)
- Test all endpoints with different user contexts
- Manipulate object IDs (sequential, UUID prediction)
- Check for IDOR across all resource types
- Test GraphQL node queries for authorization
- Tools: Burp Suite, custom scripts, Postman collections
API2: Broken Authentication
- Token generation entropy analysis
- JWT vulnerabilities (none algorithm, weak signing, no expiration)
- OAuth flow manipulation (redirect URI, state parameter)
- API key exposure and rotation
- Rate limiting on auth endpoints
- Credential stuffing protection
API3: Broken Object Property Level Authorization
- Mass assignment testing
- Excessive data exposure in responses
- Hidden field manipulation
- GraphQL field-level authorization
- Response filtering bypass
API4: Unrestricted Resource Consumption
- Rate limiting bypass techniques
- Pagination abuse (requesting all records)
- File upload size limits
- GraphQL query complexity attacks
- Batch operation abuse
- Resource-intensive query exploitation
API5: Broken Function Level Authorization
- Admin endpoint discovery
- HTTP method tampering (GET vs POST vs PUT)
- Role-based function access testing
- API versioning authorization gaps
API6: Unrestricted Access to Sensitive Business Flows
- Business logic abuse (coupon stacking, price manipulation)
- Rate limiting on sensitive operations
- Workflow bypass attacks
- Anti-automation testing
API7: Server Side Request Forgery (SSRF)
- Internal service access via API parameters
- Cloud metadata endpoint access (169.254.169.254)
- URL schema bypass (file://, gopher://, dict://)
- DNS rebinding attacks
- Redirect-based SSRF
API8: Security Misconfiguration
- CORS policy testing
- HTTP method enumeration
- Default credentials on API gateways
- Unnecessary HTTP methods enabled
- Missing security headers
- Verbose error responses
- API documentation exposure (Swagger/OpenAPI)
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.

api-security is a command published in the GitHub repository JoasASantos/ClaudeAdvancedPlugins (157 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 773 tokens. A static security scan graded it B with 2 findings (cloud metadata endpoint, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
