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 | $0.00058 | $0.01243 |
| Opus 5 | $0.00029 | $0.00622 |
| Sonnet 5 | $0.00012 | $0.00249 |
| Haiku 4.5 | $0.00006 | $0.00124 |
Grade A, and why
vulnerability-intelligence 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 9d 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.

The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Vulnerability Intelligence
Not all vulnerabilities are equal. This skill provides a prioritisation methodology that goes beyond CVSS scores.
Prioritisation Framework
1. CVSS (Common Vulnerability Scoring System)
Base score provides a starting point but should NEVER be the sole prioritisation factor.
| Score | Severity | Notes |
|---|---|---|
| 9.0-10.0 | Critical | Immediate attention, but check exploitation status |
| 7.0-8.9 | High | High priority, especially if internet-facing |
| 4.0-6.9 | Medium | Standard patching cycle unless other factors elevate |
| 0.1-3.9 | Low | Lowest priority |
2. EPSS (Exploit Prediction Scoring System)
Predicts the probability that a vulnerability will be exploited in the next 30 days (0-1 scale).
| EPSS Score | Interpretation |
|---|---|
| >0.9 | Very high probability of exploitation — treat as urgent |
| 0.5-0.9 | High probability — prioritise |
| 0.1-0.5 | Moderate probability — evaluate with other factors |
| <0.1 | Low probability — standard cycle |
3. CISA KEV (Known Exploited Vulnerabilities)
If a vulnerability is on the CISA KEV list, it IS being exploited in the wild. Patch immediately regardless of CVSS score.
4. Weaponisation Assessment
| Stage | Description | Priority Impact |
|---|---|---|
| In the wild | Active exploitation confirmed | PATCH NOW |
| Weaponised exploit | Reliable exploit available (Metasploit, commercial) | Very high priority |
| PoC available | Proof-of-concept published (GitHub, blog) | High priority — weaponisation imminent |
| Technical details | Advisory with enough detail to develop exploit | Medium — monitor for PoC |
| Advisory only | CVE assigned, limited technical detail | Standard priority |
5. Combined Prioritisation Matrix
| Priority | Criteria | Action |
|---|---|---|
| P1 — Emergency | KEV listed OR in-the-wild exploitation + internet-facing | Patch within 24 hours |
| P2 — Urgent | Weaponised exploit available + internet-facing, OR KEV + internal | Patch within 72 hours |
| P3 — High | PoC available + internet-facing, OR high CVSS + high EPSS | Patch within 7 days |
| P4 — Standard | High CVSS but no exploitation evidence + compensating controls | Patch within 30 days |
| P5 — Low | Low CVSS + internal only + strong controls | Next patch cycle or accept risk |
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.

vulnerability-intelligence is a skill published in the GitHub repository Liberty91LTD/cti-skills (18 stars, last pushed 1mo ago), licensed MIT. It adds 58 tokens to every session and 1,243 once invoked, about $0.0003 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.
