dast-devils-advocate

dast-devils-advocate is an agent for Claude Code from H-mmer/pentest-agents. It costs 53 tokens per session (3,524 once invoked), scanned B, original, no licence file.

An adversarial review agent for dynamic application security testing findings, which are results gathered by testing a running application.

In plain words
What is it for?
Use it after validation passes and before reporting to verify whether each security finding is real and properly rated.
Why use it?
It tries to disprove findings and lower their severity, helping catch exaggerated reports, assumptions, and bugs that exist only in theory.

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 B, and why

dast-devils-advocate scanned grade B with 3 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 8d 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.

Reads agent configuration directorieslowAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

3. **Bare coverage hunt.** `grep -r 'coverage-' .claude/agent-memory-local/brain/targets/`.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Cloud metadata endpointmediumServer-side request forgery

One request to 169.254.169.254 can return temporary IAM credentials.

- Can it reach cloud metadata? Actually try `169.254.169.254`, don't assume.

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.
