SkillsBench is a benchmark for measuring how effectively AI agents use modular skills—folders containing instructions, scripts, and resources—to complete specialized tasks. It helps researchers and developers evaluate both skill quality and agent behavior, including tasks that require combining multiple skills. The catalogue’s skills and instructions are evaluated as part of this workflow.
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 | $0.00063 | $0.03387 |
| Opus 5 | $0.00032 | $0.01693 |
| Sonnet 5 | $0.00013 | $0.00677 |
| Haiku 4.5 | $0.00006 | $0.00339 |
Grade C, and why
ssh-penetration-testing scanned grade C with 4 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 yesterday.
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.
Enumerates the file system for secretsmediumData exfiltration
Searching home directories for .env, .ssh, .aws or credential files is reconnaissance for credential theft.
ls -la ~/.ssh/ 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.
# Check sudo privileges 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.
~/.ssh/id_rsa 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.
# Web-accessible keys (check with curl/wget) This is a copy
97% identical to ssh-penetration-testing — 9 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

SSH Penetration Testing
Purpose
Conduct comprehensive SSH security assessments including enumeration, credential attacks, vulnerability exploitation, tunneling techniques, and post-exploitation activities. This skill covers the complete methodology for testing SSH service security.
Prerequisites
Required Tools
- Nmap with SSH scripts
- Hydra or Medusa for brute-forcing
- ssh-audit for configuration analysis
- Metasploit Framework
- Python with Paramiko library
Required Knowledge
- SSH protocol fundamentals
- Public/private key authentication
- Port forwarding concepts
- Linux command-line proficiency
Outputs and Deliverables
- SSH Enumeration Report - Versions, algorithms, configurations
- Credential Assessment - Weak passwords, default credentials
- Vulnerability Assessment - Known CVEs, misconfigurations
- Tunnel Documentation - Port forwarding configurations
Core Workflow
Phase 1: SSH Service Discovery
Identify SSH services on target networks:
# Quick SSH port scan
nmap -p 22 192.168.1.0/24 --open
# Common alternate SSH ports
nmap -p 22,2222,22222,2200 192.168.1.100
# Full port scan for SSH
nmap -p- --open 192.168.1.100 | grep -i ssh
# Service version detection
nmap -sV -p 22 192.168.1.100
Phase 2: SSH Enumeration
Gather detailed information about SSH services:
# Banner grabbing
nc 192.168.1.100 22
# Output: SSH-2.0-OpenSSH_8.4p1 Debian-5
# Telnet banner grab
telnet 192.168.1.100 22
# Nmap version detection with scripts
nmap -sV -p 22 --script ssh-hostkey 192.168.1.100
# Enumerate supported algorithms
nmap -p 22 --script ssh2-enum-algos 192.168.1.100
# Get host keys
nmap -p 22 --script ssh-hostkey --script-args ssh_hostkey=full 192.168.1.100
# Check authentication methods
nmap -p 22 --script ssh-auth-methods --script-args="ssh.user=root" 192.168.1.100
Phase 3: SSH Configuration Auditing
Identify weak configurations:
# ssh-audit - comprehensive SSH audit
ssh-audit 192.168.1.100
# ssh-audit with specific port
ssh-audit -p 2222 192.168.1.100
# Output includes:
# - Algorithm recommendations
# - Security vulnerabilities
# - Hardening suggestions
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.

ssh-penetration-testing is a skill published in the GitHub repository benchflow-ai/skillsbench (1,747 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 63 tokens to every session and 3,387 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 4 findings (enumerates the file system for secrets, asks for root, reaches for credential files). It is 97% identical to ssh-penetration-testing, differing in 9 lines, and is treated as a copy.
