One setup, every AI CLI with agnostic-AI

Agnostic-ai, an open-source tool from developer Chemaclass, generates native configuration files for 25 AI coding CLI targets from a single Markdown-and-YAML source stored in the user's repository, with a `sync --check` command that fails CI when generated files drift. The tool supports 10 portable spec kinds and translates per-target details such as model maps, tool names, and effort settings into each CLI's native format, including Claude, Codex, Cursor, and Gemini. It is installed via a curl script from the project's GitHub repository and requires no account or service.

You own the source Plain Markdown and YAML in your repo. No account, no service. import brings an existing setup in. Keep agents, skills, rules, hooks, and MCP servers in one portable source . agnostic-ai writes each tool's native files and checks them for drift.

Cite every finding with a file:line reference. Every AI coding tool ships its own config file. Adopt three and your instructions live in three places, drifting apart. agnostic-ai keeps one source in your repository and writes the rest. Same input, same bytes, so they diff cleanly. sync --check fails CI when they drift. Adding a target never changes what the others get. One rule routes to every native path and scope syntax. Easy to stop using. The generated files are yours, and they keep working. Why not just symlink one file? Each tool reads a different format at a different path. A symlink shares bytes. It cannot translate them. See how the formats diverge https://agnostic-ai.org/docs/alternatives-why-not-symlinks/ agnostic-ai init --from all Import existing AI tool files first. agnostic-ai sync --dry-run Preview every native file before writing it. agnostic-ai sync Write every native file for the targets you chose.
