agentrium: Skill for Claude Code

.claude/skills/security-review/SKILL.md

security-review is a skill for Claude Code from talayash/agentrium. It costs 17 tokens per session (232 once invoked), scanned A, original, MIT.

A security checklist for Tauri desktop apps that run terminal commands through a pseudo-terminal, a program interface that behaves like a terminal.

In plain words
What is it for?
Use it to review command injection, IPC input checks, shell escaping, filesystem paths, SQLite queries, app permissions, content security policy, and signed updates.
Why use it?
It helps identify risks where user input crosses the app, operating-system commands, files, databases, and update mechanisms.

Token cost

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.

Security

Grade A, and why

security-review 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 1mo 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.

What it actually says

Security Review Skill

Threat Surface for Agentrium

  1. PTY Command Injection - user input → xterm.js → IPC → PTY
  2. IPC Boundary - frontend can invoke any registered command
  3. Process Spawning - cmd /C wrapping needs proper escaping
  4. File System - workspace paths from user input
  5. Auto-updater - must verify signed releases
  6. SQLite - parameterized queries only

Quick Checklist

  • No .unwrap() in production Rust paths
  • No hardcoded secrets/tokens/passwords
  • No eval(), innerHTML, dangerouslySetInnerHTML
  • All IPC commands validate inputs
  • cmd /C calls escape user strings
  • SQLite uses parameterized queries
  • Tauri capabilities are minimal
  • CSP configured in tauri.conf.json
  • Auto-updater verifies signatures
Changes

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.
