canister-audit

82 / 100 · Low risk

Fine to try. Some of what it can do is expected: a security skill usually runs scanners and checks websites.

Deep security audit of an Internet Computer Rust canister repo - detect an ic-cdk canister, model its invariants and trust boundaries first, run a Semgrep IC ruleset plus cargo-audit/osv (best-effort), then a bounded agentic pass that hunts a path breaking each invariant against the 12 canister-security pitfalls, triage, adversarially refute, prove a confirmed HIGH/CRITICAL with a PocketIC reproduction through the shared PoC gate, and route each finding through the shared responsible-disclosure…

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'canister-audit' ] || [ -L ~/.agents/skills/'canister-audit' ]; then echo 'A skill folder named canister-audit already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/aeonfun/aeon' "$d" && git -C "$d" checkout --quiet '5981e1caa880e9bc186e1bf9f27c095b3ba9ef22' -- 'skills/canister-audit' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/canister-audit' ~/.agents/skills/'canister-audit' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'canister-audit' ~/.claude/skills/'canister-audit' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
