-## Installation
+## Utilities
 
-Current install targets:
+### Install shared baseline rules
 
-- Codex: `AGENTS.md` -> `~/.codex/AGENTS.md`
-- OpenCode: `AGENTS.md` -> `~/.config/opencode/AGENTS.md`
+`install-rules.py` currently targets:
+
+- Codex: `AGENTS.md` -> `${CODEX_HOME:-~/.codex}/AGENTS.md`
+- OpenCode: `AGENTS.md` -> `${XDG_CONFIG_HOME:-~/.config}/opencode/AGENTS.md`
 - Claude Code: `AGENTS.md` -> `~/.claude/CLAUDE.md`
 - Gemini: `AGENTS.md` -> `~/.gemini/GEMINI.md`
 
 Run:
 
 ```bash
-python3 agents/install-agents.py
+python3 agents/install-rules.py
 ```
 
-The installer handles each target independently and skips it if the destination directory does not
-already exist.
+Notes:
+
+- each target is handled independently
+- missing target directories are skipped
+- existing target file/symlink is replaced with a symlink to this repo copy
