Fine to try.

By DavidSouther/ailly (GitHub) · other · 16 stars · scanned at commit 3b72cbd

Use when authoring, iterating, or refining a skill against an Ailly eval harness, driving a SKILL.md to a falsification gate (improved > 0 and regressed == 0) through assemble/run/eval/report. The harness-assembling loop pairs with ailly-skill-eval (which describes the harness anatomy) and delegates the authoring algorithm to skill-creator. Distinct from building the harness by hand or running one ad-hoc eval against a single prompt.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

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

if [ -e ~/.agents/skills/'skill-forge' ] || [ -L ~/.agents/skills/'skill-forge' ]; then echo 'A skill folder named skill-forge already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/DavidSouther/ailly' "$d" && git -C "$d" checkout --quiet '3b72cbd7d7d6d933ac8e173639b08c833d2a844a' -- 'harness/skills/skill-forge' && mkdir -p ~/.agents/skills && cp -R "$d"/'harness/skills/skill-forge' ~/.agents/skills/'skill-forge' && 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/'skill-forge' ~/.claude/skills/'skill-forge' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
