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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00025 | $0.00461 |
| Opus 5 | $0.00013 | $0.00230 |
| Sonnet 5 | $0.00005 | $0.00092 |
| Haiku 4.5 | $0.00003 | $0.00046 |
Grade A, and why
authorized-web-pentest 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 10d 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.

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

Authorized Web Pentest
Use this only for defensive testing of applications the user owns or has written authorization to test.
Authorization Gate
Before active testing, ask the user to confirm:
Confirm: the target URL is
<target>, you own this application or have written authorization to test it, and active security testing is allowed during this session.
Do not send payloads or scans until the user confirms. Passive source review and reading public pages is fine.
Scope File
Create an engagement directory:
ENGAGEMENT="web-pentest-$(date +%Y%m%d-%H%M%S)"
mkdir -p "$ENGAGEMENT"/{evidence,findings,reports}
printf "%s\n" "<hostname>" > "$ENGAGEMENT/scope.txt"
Every active request must target a host in scope.txt. Stop on off-scope redirects.
Phases
- Setup:
- Record authorization, target, scope, and time window.
- Passive/source recon:
- Map routes, auth, sinks, trust boundaries, and deployment config from code.
- Read-only live recon:
- Headers, robots/sitemap, public links, login surface, XHR endpoints.
- Vulnerability analysis:
- Injection, XSS, auth/authz, SSRF, file handling, deserialization, CORS, security headers.
- Proof:
- Every finding needs a reproducible request/response or code path.
- No destructive payloads without explicit approval.
- Report:
- Findings, severity, impact, evidence, reproduction, minimal fix.
Rules
- No exploit, no report. Suspicions without proof are notes, not findings.
- Rate-limit active requests.
- Redact credentials and tokens in chat. Store full values only in local evidence files when needed.
- Cloud metadata hosts are off-limits unless explicitly authorized and owned.
- A clean run means "no exploitable issue found in this scope/time/method," not "secure."
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.

authorized-web-pentest is a skill published in the GitHub repository metaspartan/cybara (28 stars, last pushed today), licensed MIT. It adds 25 tokens to every session and 461 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
