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: 6 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 | $0.00081 | $0.02795 |
| Opus 5 | $0.00041 | $0.01398 |
| Sonnet 5 | $0.00016 | $0.00559 |
| Haiku 4.5 | $0.00008 | $0.00280 |
Grade A, and why
conducting-network-penetration-test 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 7d 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.

Conducting Network Penetration Test
When to Use
- Assessing the security posture of internal or external network infrastructure before or after deployment
- Validating firewall rules, network segmentation, and access controls under realistic attack conditions
- Identifying exploitable vulnerabilities in network services, protocols, and configurations
- Meeting compliance requirements for PCI-DSS, HIPAA, SOC 2, or ISO 27001 that mandate periodic penetration testing
- Evaluating the effectiveness of IDS/IPS, SIEM, and SOC detection capabilities against real attack traffic
Do not use for testing networks without explicit written authorization from the asset owner, against production systems without a pre-approved change window and rollback plan, or for denial-of-service testing unless explicitly scoped and authorized.
Prerequisites
- Signed Rules of Engagement (RoE) document specifying target IP ranges, excluded hosts, testing hours, and emergency contacts
- Written authorization letter (get-out-of-jail letter) from the network owner
- Dedicated testing laptop with Kali Linux or equivalent distribution with up-to-date tools
- VPN or direct network access to the target scope as defined in the RoE
- Out-of-band communication channel with the client's incident response team
- Scope document listing in-scope IP ranges, domains, and any explicitly excluded systems (medical devices, SCADA, critical infrastructure)
Workflow
Step 1: Pre-Engagement and Scope Validation
Validate the scope by confirming IP ranges with the client. Verify that all IP addresses in scope are owned by the client using ARIN/RIPE WHOIS lookups. Confirm testing windows, escalation procedures, and any sensitivity constraints. Set up the testing environment with a dedicated VM, VPN connection, and logging enabled on all tools. Create a timestamped activity log that records every command executed, every scan launched, and every exploit attempted throughout the engagement.
Step 2: Host Discovery and Network Mapping
What ships with it
3 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.
- 7d ago First seen · 208 lines · 81 tokens per session scan A b7521af5038b
conducting-network-penetration-test is a skill published in the GitHub repository 26zl/cybersec-toolkit (52 stars, last pushed yesterday), licensed MIT. It adds 81 tokens to every session and 2,795 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 2026-09-03.
