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.

SkillSpector: 7 findings, up to critical
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00045 | $0.03110 |
| Opus 5 | $0.00023 | $0.01555 |
| Sonnet 5 | $0.00009 | $0.00622 |
| Haiku 4.5 | $0.00005 | $0.00311 |
Grade A, and why
conducting-internal-network-penetration-test 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 8d 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 rootlowPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
sudo responder -I eth0 -dwPv Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Conducting Internal Network Penetration Test
Overview
An internal network penetration test simulates an attacker who has already gained access to the internal network or a malicious insider. The tester operates from an "assumed breach" position — typically a standard domain workstation or network jack — and attempts lateral movement, privilege escalation, credential harvesting, and data exfiltration to determine the blast radius of a compromised endpoint.
When to Use
- When conducting security assessments that involve conducting internal network penetration test
- When following incident response procedures for related security events
- When performing scheduled security testing or auditing activities
- When validating security controls through hands-on testing
Prerequisites
- Signed Rules of Engagement with internal network scope
- Network access: physical Ethernet drop or VPN connection to internal VLAN
- Standard domain user credentials (assumed breach model) or unauthenticated access
- Testing laptop with Kali Linux, Impacket, Responder, BloodHound
- Coordination with IT/SOC for monitoring and emergency contacts
Legal Notice: This skill is for authorized security testing and educational purposes only. Unauthorized use against systems you do not own or have written permission to test is illegal and may violate computer fraud laws.

What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

conducting-internal-network-penetration-test is a skill published in the GitHub repository 26zl/cybersec-toolkit (54 stars, last pushed today), licensed MIT. It adds 45 tokens to every session and 3,110 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
