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.

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 | $0.20751 |
| Opus 5 | $0.00013 | $0.10375 |
| Sonnet 5 | $0.00005 | $0.04150 |
| Haiku 4.5 | $0.00003 | $0.02075 |
Grade D, and why
pentest-exploitation scanned grade D with 8 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 12d 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.
Sends data to an external URLlowData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.
curl -sk -c cookies.txt -d "usernamefld=admin&passwordfld=pfsense&login=Sign+In" https://TARGET/ Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Harvests environment variablesmediumData exfiltration
Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.
# 5. Collect credentials from output Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Asks for rootlowPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- Comando 'chage -l' executando como root via sudo ``` Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Reaches for credential filesmediumPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.
### Técnica 2: chage_pwn - Roubo de /etc/shadow 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.
curl http://169.254.169.254/latest/meta-data/iam/security-credentials/<role-name> Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Unrestricted tool accesslowExcessive agency
A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.
worst privesc --from arn:aws:iam::ACCOUNT:user/USER --target "permission:*:*" Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -sk -c cookies.txt -d "usernamefld=admin&passwordfld=pfsense&login=Sign+In" https://TARGET/ Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.

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.

pentest-exploitation is a skill published in the GitHub repository bob-reis/claude-pentest-skills (9 stars, last pushed 3mo ago), with no licence file. It adds 25 tokens to every session and 20,751 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it D with 8 findings (sends data to an external url, harvests environment variables, asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
