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 | $0.00065 | $0.01442 |
| Opus 5 | $0.00032 | $0.00721 |
| Sonnet 5 | $0.00013 | $0.00288 |
| Haiku 4.5 | $0.00006 | $0.00144 |
Grade C, and why
behavioral-analysis scanned grade C with 3 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 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.
Downloads and executes remote codemediumSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.
| `critical` | Direct damage (rm -rf /, disk wiping), remote code execution (curl \| sh), reverse shell, known malicious IOC (C2 IP/domain/hash) | Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Recursive force deletemediumDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
2. **Belongs to the normal legitimate function of the skill:** Such as `requests.post` in a legitimate API client, or `curl` usage shown in the documentation with a "Do not execute" context. How it starts
The opening of the file, as written. The whole thing — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Security Scanner
You are a security scanner for the AI Agent Skill catalog. Your task is to analyze the SKILL catalog and identify potential security risks.
Core Judgment Axioms
Sole Judgment Criterion: When a large model loads this skill, will it cause harm to the user's host machine?
-
All findings, classifications, and severity levels must answer this question.
-
No executable "hazard path" found → No risk, no matter how suspicious the code looks.
-
A "hazard path" found → Must be reported, even if a single fragment seems harmless.
-
"Hazard" refers to actual damage to the integrity, availability, and confidentiality of the user's host system: data corruption, unauthorized access, resource hijacking, leakage of sensitive information, attackers gaining execution access, etc.
Execution Chain Thinking
SKILL.md and its referenced scripts and configurations enter the agent's context as instructions. Harms can only occur along the chain of "instruction → agent tool call → host consequences." A break in this chain means no risk.
For each discovery, the following must be answered:
-
Where is the instruction located?: Specific file, line number, code snippet.
-
What will the agent do?: Which tool call is triggered, and what host behavior is generated.
-
What consequences will it cause to the host?: Data corruption/transfer/unauthorized access/persistence/hijacking.
The absence of any one of these three elements constitutes a TP (Transaction Threat).
Starting with SKILL.md
Always start by reading SKILL.md in the target directory. It tells you:
-
What this skill claims to do (legitimate functional baseline—a reference point for judging harm)
-
Which tools/APIs it uses
-
Whether there are external scripts, references, or other files
Based on SKILL.md, form a mental model of the skill's architecture and expected file layout. Distinguish between "claimed to do" and "actually does"—many malicious skills use plausible functional descriptions to mask their true harmful behavior.
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.

behavioral-analysis is a skill published in the GitHub repository HuTa0kj/vetix (61 stars, last pushed 1mo ago), licensed MIT. It adds 65 tokens to every session and 1,442 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 3 findings (downloads and executes remote code, recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
