ai-coding-skills

Cross-agent skill collection for Codex, Claude Code, and OpenCode.

This repo is organized similarly to obra/superpowers and is designed to scale to many skills over time.

Goals

• Keep skills portable across coding agents.
• Keep each skill self-contained (skills/<skill-name>/SKILL.md + optional resources).
• Enforce requirement checks for skills that depend on Superpower skills.

Requirement Gate (Superpowers dependency)

If a skill depends on Superpower skills (https://github.com/obra/superpowers), it must include an explicit prerequisite block in SKILL.md and fail fast with clear instructions when requirements are missing.

See: docs/requirements-gate.md

Compatibility Policy

Each skill added to this repo should specify support status for:

• Codex
• Claude Code
