# One setup, every AI CLI with agnostic-AI > Source: > Published: 2026-09-23 23:10:16+00:00 ### 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. Recommended installer[All install options](https://agnostic-ai.org/docs/installation/) `curl -fsSL https://raw.githubusercontent.com/Chemaclass/agnostic-ai/main/scripts/install.sh | bash` 25 targets. 10 portable spec kinds. Byte-stable output. ``` --- name: reviewer description: Reviews a diff for bugs, style, and architectural issues. tools: [Read, Grep, Glob] model: claude: claude-opus-5-5 codex: gpt-6-sol effort: high --- Read the diff. Report bugs, unclear naming, and missing tests. Cite every finding with a `file:line` reference. ``` Markdown with YAML frontmatter. The per-target model map resolves to `model: claude-opus-5-5`, `effort` keeps its name, and the three tools pass through as written. ``` --- name: reviewer description: Reviews a diff for bugs, style, and architectural issues. tools: - Read - Grep - Glob model: claude-opus-5-5 effort: high --- Read the diff. Report bugs, unclear naming, and missing tests. Cite every finding with a `file:line` reference. ``` TOML, not Markdown. The map resolves to `gpt-6-sol`, `effort` becomes Codex's own `model_reasoning_effort`, the body becomes `developer_instructions`, and there is no `tools` key at all. ``` # Generated by agnostic-ai. Do not edit this file directly; edit specs under .agnostic-ai/ and run `agnostic-ai sync`. name = "reviewer" description = "Reviews a diff for bugs, style, and architectural issues." model = "gpt-6-sol" model_reasoning_effort = "high" developer_instructions = """ Read the diff. Report bugs, unclear naming, and missing tests. Cite every finding with a `file:line` reference. """ ``` `tools` and `effort` are dropped. Sync says why: Cursor subagents have neither field, so use `readonly: true` for a coarse restriction and put effort in the model id, such as `claude-opus-5[effort=high]`. ``` --- name: reviewer description: Reviews a diff for bugs, style, and architectural issues. --- Read the diff. Report bugs, unclear naming, and missing tests. Cite every finding with a `file:line` reference. ``` The tool names are translated into Gemini vocabulary. No model line, because the map has no gemini key and no default. No effort line either: Gemini agents have no effort key, and sync prints a note. ``` --- name: reviewer description: Reviews a diff for bugs, style, and architectural issues. tools: - read_file - grep_search - glob --- Read the diff. Report bugs, unclear naming, and missing tests. Cite every finding with a `file:line` reference. ``` The tools pass through untranslated, and `effort` keeps its name. No model line here either, for the same reason as Gemini. ``` --- name: reviewer description: Reviews a diff for bugs, style, and architectural issues. tools: - Read - Grep - Glob effort: high --- Read the diff. Report bugs, unclear naming, and missing tests. 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. The five most complete integrations, across six of the ten spec kinds. The other four: [settings](https://agnostic-ai.org/docs/spec-format/#settings), [review](https://agnostic-ai.org/docs/spec-format/#reviews), [environment](https://agnostic-ai.org/docs/spec-format/#environments), [ignore](https://agnostic-ai.org/docs/spec-format/#ignore). **Native** uses the target's dedicated format automatically. **Opt-in** links to the setting you need. | Target | Agents | Skills | Rules | Hooks | MCP | Commands | |---|---|---|---|---|---|---| | [Claude](https://agnostic-ai.org/docs/targets/claude/) | AgentsNative | SkillsNative | RulesNative | HooksNative | MCPNative | CommandsNative | | [Codex](https://agnostic-ai.org/docs/targets/codex/) | AgentsNative | SkillsNative | RulesNative | HooksNative | MCPNative | Commands [Opt-in](https://agnostic-ai.org/docs/targets/codex/#config-keys) | | [Cursor](https://agnostic-ai.org/docs/targets/cursor/) | AgentsNative | SkillsNative | RulesNative | HooksNative | MCPNative | CommandsNative | | [Gemini](https://agnostic-ai.org/docs/targets/gemini/) | AgentsNative | SkillsNative | RulesNative | HooksNative | MCPNative | CommandsNative | | [Copilot](https://agnostic-ai.org/docs/targets/copilot/) | AgentsNative | SkillsNative | RulesNative | HooksNative | MCPNative | CommandsNo output | What shipped in agnostic-ai, and what changed upstream in the tools it targets.
