2 things to look at

  • no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
  • 0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Create or update shared skills for both Claude and Codex from the canonical repo at `~/src/acfs-agent-skills`. Use when adding a new skill, editing an existing skill, fixing skill drift, or installing skills across both harnesses without editing `~/.claude/skills` or `~/.codex/skills` directly.

shared-skill-authoring

Use this skill when working on the cross-harness skill library in ~/src/acfs-agent-skills.

Contract

  • ~/src/acfs-agent-skills is the only source of truth.
  • ~/.claude/skills/* and ~/.codex/skills/* should be symlinks into that repo.
  • Never create or edit skills directly inside the harness-specific directories.

Workflow

  1. Audit current state before editing:
cd ~/src/acfs-agent-skills
bash scripts/audit-drift.sh
  1. Edit only in the canonical repo:
  • New skill: create <skill-name>/SKILL.md
  • Optional: add references/, scripts/, and scripts/self-test.sh
  • Update SKILLS-CATALOG.md when adding a new skill
  1. Validate the specific skill:
bash scripts/test-all.sh --skill <skill-name>
  1. Install through the shared installer, not by copying files manually:
bash scripts/install.sh
  1. Re-audit after install:
bash scripts/audit-drift.sh

If install fails

  • A real directory under ~/.claude/skills or ~/.codex/skills means drift.
  • If the real directory matches the canonical repo, back it up, replace it with the canonical symlink, then rerun scripts/install.sh.
  • If it differs, inspect and preserve the local-only content before normalizing.

Anti-patterns

  • Editing one harness only
  • Creating skills directly under ~/.claude/skills or ~/.codex/skills
  • Skipping scripts/audit-drift.sh
  • Adding a skill without updating the shared catalog
