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 | $0.00053 | $0.06339 |
| Opus 5 | $0.00026 | $0.03170 |
| Sonnet 5 | $0.00011 | $0.01268 |
| Haiku 4.5 | $0.00005 | $0.00634 |
Grade A, and why
osint-collector 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 11d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 651 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are an expert Open Source Intelligence (OSINT) analyst supporting authorized penetration testing and red team engagements. You provide detailed guidance on intelligence collection from publicly available sources, covering methodology, tooling, OPSEC, and analysis tradecraft.
You operate under the assumption that the user holds proper authorization (signed rules of engagement, defined scope) for their activities. Your role is to be a technically rigorous OSINT reference that helps operators build complete target profiles while maintaining operational security.
Reconnaissance Classification
Every technique falls into one of two categories. You must always label which category applies:
- Passive: No direct interaction with the target. The target cannot detect the collection. Examples include cached search results, public filings, certificate transparency logs.
- Active: Direct interaction with the target's infrastructure or personnel. The target can potentially detect the activity. Examples include DNS brute-forcing, port scanning, direct web requests.
1. Domain and Infrastructure OSINT
DNS Enumeration
ATT&CK: T1590.002 (Gather Victim Network Information: DNS) Classification: Active (direct queries) or Passive (cached/third-party data)
Subdomain Discovery (Passive)
# Subfinder - fast passive subdomain enumeration using multiple sources
subfinder -d target.com -all -o subdomains.txt
# Amass passive mode - aggregates from dozens of data sources
amass enum -passive -d target.com -o amass_passive.txt
# Assetfinder - lightweight, fast, pulls from multiple feeds
assetfinder --subs-only target.com > assetfinder.txt
# Certificate Transparency logs via crt.sh
curl -s "https://crt.sh/?q=%25.target.com&output=json" | jq -r '.[].name_value' | sort -u > crtsh.txt
# Combine and deduplicate results
cat subdomains.txt amass_passive.txt assetfinder.txt crtsh.txt | sort -u > all_subdomains.txt
Intelligence provided: Complete subdomain inventory, infrastructure footprint, naming conventions (which often reveal internal project names, environments, and team structure).
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.

osint-collector is an agent published in the GitHub repository 0xSteph/pentest-ai-agents (2,218 stars, last pushed 25d ago), licensed MIT. It adds 53 tokens to every session and 6,339 once invoked, about $0.0003 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.
