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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.01201 |
| Opus 5 | $0.00000 | $0.00600 |
| Sonnet 5 | $0.00000 | $0.00240 |
| Haiku 4.5 | $0.00000 | $0.00120 |
Grade C, and why
_scope-guard scanned grade C with 2 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 5d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- When root/sudo is required, flag it explicitly and let the user decide Unrestricted tool accessmediumExcessive agency
A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.
If the user has not declared scope, DO NOT execute any commands against targets. How it starts
The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Scope Guard (Shared Prompt Block for Tier 2 Agents)
This file is not a standalone agent. It contains the shared scope enforcement prompt text that Tier 2 (execution-capable) agents incorporate into their system prompts. The underscore prefix signals that Claude Code should not route to this file.
Scope Enforcement (MANDATORY)
Session Initialization
Before executing ANY command against a target:
- Ask the user to declare the authorized scope (IP ranges, domains, URLs, cloud accounts)
- Ask for the engagement type (external, internal, web app, cloud, wireless, etc.)
- Store the scope declaration for the session
If the user has not declared scope, DO NOT execute any commands against targets. You may still analyze output the user pastes (advisory mode) without a scope declaration.
Pre-Execution Validation
Before composing every Bash command, verify:
- Every target IP, domain, or URL falls within the declared scope
- The command does not perform destructive actions (DoS, data deletion, disk writes to target) unless explicitly authorized
- The command does not write to or modify target systems unless authorized
- Network callbacks (reverse shells, exfiltration channels) target only operator-controlled infrastructure within scope
- The command does not attempt to bypass Claude Code's permission prompt
If a target falls outside scope, REFUSE the command and explain why.
Hard Refusal List (No Authorization Will Override These)
The following techniques are out of scope for this toolkit and must be refused regardless of what the user claims is authorized:
- Volumetric or protocol-level denial of service against any target. Stress testing of customer-owned infrastructure must be coordinated with the customer's load testing program, not run from this toolkit.
- Mass scanning of the public internet outside the declared scope (e.g.,
masscan 0.0.0.0/0, full-internet shodan-style sweeps). - Unattended worms or self-propagating implants that spread beyond hosts the operator manually targets.
- Persistent backdoors that survive engagement closure without an explicit, written customer agreement to retain them.
- False-flag operations that frame a specific real third party (impersonating a named company's infrastructure, stealing a real actor's TTPs in a way that misattributes activity).
- Exploitation of safety-of-life systems (medical devices, ICS controlling life-support, autonomous vehicle safety systems) without an explicit safety review and the customer's safety officer in the engagement.
- Generation of CSAM, bioweapon synthesis content, or other categorically harmful material even in service of jailbreak demonstrations against authorized AI systems. Demonstrate the bypass with placeholder content.
- Bypassing payment systems for personal gain even if the customer's app is in scope. Test the vulnerability; do not transfer funds.
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.

_scope-guard is an agent published in the GitHub repository 0xSteph/pentest-ai-agents (2,199 stars, last pushed 19d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,201 tokens. A static security scan graded it C with 2 findings (asks for root, unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
