7.6/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 6/10, docs & honesty 3/5.

How do I install ACOS Meta?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use ACOS Meta with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Verdict: Works with setup

Tested: Jul 15, 2026
Environment: Claude Code 2.x (agent harness)

Reads as a private wiki page about the author's own ACOS project rather than a portable skill: it cites live paths like ~/agentic-creator-os/ and ~/frankx/.claude/skills/frankx-meta/ that ship in separate, uncloned repos, and its own bundled reference file admits the hook system (.claude-flow/audit.jsonl, hooks/ dir) it instructs you to debug is largely unshipped/aspirational.

What ACOS Meta does

Explains the architecture, hook system, and skill/command/agent conventions of ACOS (agentic-creator-os), a specific author's personal Claude Code meta-system. Triggers on 'ACOS', onboarding to it, or debugging its hooks. Useful only to someone who already runs or is building the actual ACOS project at ~/agentic-creator-os/, which is not included in this repo.
