Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Property-based testing and fuzzing using Echidna for smart contracts. Includes invariant definition, corpus management, coverage analysis, and CI/CD integration for comprehensive security testing.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

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

if [ -e ~/.agents/skills/'echidna-fuzzer' ] || [ -L ~/.agents/skills/'echidna-fuzzer' ]; then echo 'A skill folder named echidna-fuzzer already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/a5c-ai/babysitter' "$d" && git -C "$d" checkout --quiet 'feb68abe397acc14f32b34984975c48fedba2b33' -- 'library/specializations/cryptography-blockchain/skills/echidna-fuzzer' && mkdir -p ~/.agents/skills && cp -R "$d"/'library/specializations/cryptography-blockchain/skills/echidna-fuzzer' ~/.agents/skills/'echidna-fuzzer' && 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/'echidna-fuzzer' ~/.claude/skills/'echidna-fuzzer' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
