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

How iii works and the iii-sdk surface for authoring workers, functions, and observers. Teaches the ordered way to gain a capability before writing code — (1) check functions already registered in the engine, (2) search the public registry via iii-directory, (3) build a worker. Single self-contained skill — meant for system-prompt injection; do not re-fetch.

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/'iii' ] || [ -L ~/.agents/skills/'iii' ]; then echo 'A skill folder named iii already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/iii-hq/iii' "$d" && git -C "$d" checkout --quiet 'fd9719faa18f77c4bc94f6480144b1c1707142a2' -- 'engine/src/workers/engine_fn/skills' && mkdir -p ~/.agents/skills && cp -R "$d"/'engine/src/workers/engine_fn/skills' ~/.agents/skills/'iii' && 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/'iii' ~/.claude/skills/'iii' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
