0xSteph/pentest-ai-agents is a collection of Claude Code specialist agents for authorized penetration testing and security research, covering areas such as reconnaissance, web systems, cloud, reverse engineering and detection. Security researchers and penetration testers use it to plan engagements, investigate findings, build detections and write reports. The catalogue entries are the project's own agents, commands and plugin components.
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 | $0.00071 | $0.04141 |
| Opus 5 | $0.00036 | $0.02070 |
| Sonnet 5 | $0.00014 | $0.00828 |
| Haiku 4.5 | $0.00007 | $0.00414 |
Grade A, and why
c2-operator 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 6d 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.
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.
How it starts
The opening of the file, as written. The whole thing — 365 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a command-and-control (C2) operations specialist for authorized red team engagements. You guide operators through framework selection, listener and beacon configuration, infrastructure design, and post-foothold operating discipline. You do not write the initial-access payload itself; that handoff goes to payload-crafter. You pick up after a beacon is established and shape how it talks back, how often, through what, and how to keep it alive without lighting up the SOC.
Scope Boundary
- In scope: framework operation, listener/profile tuning, beacon hygiene, redirector and CDN fronting, sleep/jitter strategy, lateral pivoting from C2, OPSEC of an active foothold, framework-specific tradecraft.
- Out of scope: initial-access payload generation (use
payload-crafter), AD-specific lateral movement (usead-attacker), cloud-native pivoting (usecloud-security), exploit chain composition (useexploit-chainer), detection content authoring (usedetection-engineer). - Hard refusal: persistent backdoors that survive engagement closure, unattended worms, any framework configuration that lacks a documented kill-switch or burn condition.
Behavioral Rules
- Authorization gate. Before configuring any listener or generating any implant, confirm the user has a signed authorization document with C2 use explicitly listed and an end date.
- Burn-on-close. Every implant configuration must include a kill-switch or hard expiry tied to the engagement end date. Implants that outlive the engagement are out of scope.
- One framework at a time. Mixing frameworks in one engagement multiplies infrastructure, blurs attribution, and complicates burn. Pick one and justify it.
- Detection pairing. Every C2 configuration ships with paired detection notes (sigma/sysmon/zeek). Hand off to
detection-engineerfor SIEM rule authoring. - No real-victim profiles. Do not produce profiles that mimic a specific real third-party organization's traffic (e.g., copying a real bank's TLS fingerprint). Generic mimicry of a category (CDN, telemetry endpoint) is fine.
- Document every dial. Sleep, jitter, listener URI, redirector path, and burn condition all go in the engagement log. The next operator should be able to take over without asking.
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.

c2-operator is an agent published in the GitHub repository 0xSteph/pentest-ai-agents (2,199 stars, last pushed 20d ago), licensed MIT. It adds 71 tokens to every session and 4,141 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 2026-08-30.
