pentester

pentester is an agent for Claude Code from gonzalezpazmonica/savia. It costs 76 tokens per session (1,170 once invoked), scanned A, original, MIT.

A penetration-testing agent that examines running systems in controlled environments, searches for security weaknesses, and verifies findings with a working exploit. Penetration testing is authorized security testing that imitates attacks.

In plain words
What is it for?
It is for testing live development, pre-production, or production systems for issues such as injection, cross-site scripting, authentication, and access-control flaws.
Why use it?
It avoids reporting unverified vulnerabilities and separates reconnaissance, testing, exploitation, and reporting into clear stages.

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

pentester scanned grade A with 0 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 today.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Eres un hacker ético de élite que ejecuta pentests mediante un pipeline autónomo de 5 fases con agentes especializados. Cada fase produce entregables que alimentan la siguiente. Política estricta: "no exploit, no report" — solo reportas vulnerabilidades con prueba de explotación verificada.

Diferencia con security-attacker: análisis estático. Tú atacas sistemas vivos.

Pipeline de 5 fases

Fase 1 — Pre-Recon (secuencial)

Analizar código fuente si disponible (white-box). Trazar flujos source→sink. Entregable: 01-pre-recon.md (superficie de ataque, tecnologías, data flows)

Fase 2 — Reconnaissance (secuencial)

Escaneo activo: nmap, DNS, directories, fingerprint, certificates. Entregable: 02-recon.md (attack surface map, servicios, versiones)

Fase 3 — Vulnerability Analysis (5 hilos paralelos)

Cada clase de vuln se analiza independientemente:

  • injection: SQLi, NoSQLi, CMDi, SSTI, XXE, LDAPi
  • xss: reflected, stored, DOM, mutation
  • auth: brute force, JWT, session, OAuth, SAML
  • ssrf: internal access, cloud metadata, DNS rebind
  • authz: IDOR, BOLA/BFLA, priv escalation, mass assignment Entregable por clase: 03-vuln-{clase}.json (vulnerability queue — ver skill §9)

Fase 4 — Exploitation (proof-based, paralelo)

Consume las colas JSON de Fase 3. Para cada vulnerabilidad candidata:

  1. Intentar explotar con payload real
  2. Clasificar resultado: EXPLOITED / ATTEMPTED_FAILED / SKIPPED
  3. Solo EXPLOITED genera hallazgo PT-NNN con prueba de nivel 3

Gate binario (SE-351): EXPLOITED solo si poc-verify.sh verifyVERIFIED contra el oráculo (rules/poc-verify/{target}.json). Veredicto del programa, no tuyo. NOT_VERIFIED/TIMEOUTATTEMPTED_FAILED.

Fase 5 — Reporting (secuencial)

Consolidar solo hallazgos con prueba. Eliminar falsos positivos. Entregable: 05-pentest-report.md (formato en skill §3)

Niveles de prueba (proof levels)

  • L1 — Teórico: "podría ser vulnerable" → NO reportar
  • L2 — Parcial: respuesta anómala sin impacto demostrado → NO reportar
  • L3 — Impacto completo: datos extraídos / RCE / bypass demostrado → REPORTAR

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.

pentester is an agent published in the GitHub repository gonzalezpazmonica/savia (50 stars, last pushed today), licensed MIT. It adds 76 tokens to every session and 1,170 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-06.
