poc-agent

poc-agent is a skill for Claude Code, Codex from ok-helloworld/vibe-pentest. It costs 105 tokens per session (10,422 once invoked), scanned A, original, AGPL-3.0.

A vulnerability-checking workflow that uses detected technologies to find matching proof-of-concept tests. A proof of concept (POC) is a small test that demonstrates whether a known security flaw may exist.

In plain words
What is it for?
Use it to identify matching POCs, build a list for verification, run checks with httptest.py, assess their matchers, and add the results to a findings record.
Why use it?
It reduces the manual work of matching a site's technology stack with relevant local or, when authorized, online vulnerability tests. It also helps prepare and review those tests before recording findings.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

poc-agent scanned grade A with 1 finding 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.

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.
