Security Review
Review code for security issues before merge — authz gaps, injection, secrets, unsafe defaults, SSRF, path traversal. Use when reviewing a PR, auditing a diff, shipping auth/payments/uploads, or when the user asks for a security review or OWASP check.

From automated source analysis of v0.1.0. “Used” means the capability is present in the source — more access means more to trust, not that it’s unsafe.

Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Security Review
Review the current change like a security-minded senior. Prefer concrete findings over generic advice.
Scope
Focus on the diff and directly related call paths. Do not audit the whole repo unless asked.
Checklist
Auth & access
- [ ] Every sensitive action checks authentication and authorization
- [ ] IDs from the client are not trusted for ownership (
userIdin body ≠ proof) - [ ] Admin/debug routes are gated; no "temporary" open endpoints
Input & data
- [ ] User input is validated at the boundary (type, length, allowlist)
- [ ] SQL/NoSQL/search queries are parameterized — no string concat
- [ ] HTML/Markdown/user content is escaped or sanitized where rendered
- [ ] File uploads: size limits, type allowlist, stored outside web root, randomized names
- [ ] Path joins cannot escape intended directories (
../)
Secrets & config
- [ ] No secrets in source, logs, client bundles, or example env files with real values
- [ ] New env vars documented; defaults are safe for production
- [ ] Tokens/passwords not written to analytics or error trackers
Network & server
- [ ] Outbound fetches do not accept raw user URLs without allowlisting (SSRF)
- [ ] CORS is least-privilege; credentials only when required
- [ ] Cookies:
HttpOnly,Secure,SameSitewhere applicable
Dangerous APIs
- [ ] No
eval,dangerouslySetInnerHTML, shellexecwith unsanitized input - [ ] Deserialization of untrusted data is avoided or hardened
- [ ] Crypto/auth libraries are standard — no home-rolled JWT/crypto
Output format
Group findings:
| Severity | Rule | Where | Why it matters | Fix | |----------|------|-------|----------------|-----| | Critical / High / Medium / Low / Note | short name | file:line or symbol | 1 sentence | concrete change |
End with:
- Blockers — must fix before merge
- Safe to ship with follow-ups — optional
If no issues: say so explicitly and list what you checked.
