Reliability & compatibility
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 Auditor
Adversarial security-audit skill for the jeff pipeline.
Use this skill when you need an adversarial review that tries to break assumptions and surface exploitable weaknesses.
Load Order
For code work, load these first:
code-standards- language-specific skills, if present
testing(when modifying checks)
Then load security-auditor.
Adversarial Posture (Anti-Shirk Contract)
- Assume vulnerabilities exist until disproven by evidence.
- Treat missing evidence as a risk signal, not a clean bill of health.
- Never return
PASSwithout full coverage ledger output. - Do not stop at regex hits: confirm exploit path context when possible.
- Keep findings actionable with CWE mapping, exploit risk, and concrete remediation.
- The implementer must never be the auditor. Whoever wrote or changed the code under review cannot sign off on its security; delegate the audit to an independent agent and never self-assess inline.
Deterministic Entry Point
The audit runner is scripts/review-security.sh, bundled in this skill's own directory. When this skill loads, its absolute location is given to you as the skill's base directory (the Base directory for this skill: … line in the skill preamble). Run the script by that absolute path, keeping your working directory in the target repo so the scan resolves the code under review from the cwd:
"/scripts/review-security.sh" [scope] [flags]
Do not filesystem-search for the script; resolve it from the announced base directory.
Default Checks
- Hardcoded secrets and key material
- Injection sinks (SQL, shell/command, path traversal)
- Insecure deserialization
- Weak crypto/hash usage
- Dangerous dynamic execution (
eval,exec, deserialization gadgets) - TLS verification disabled / insecure transport
- XSS-prone patterns
- Sensitive data logging
- Dependency audit attempts (when manifest + tool exist)
