## Task Install or refresh the aihaus overlay into the current working directory by dispatching to `pkg/scripts/install.sh` with `--target .`. Fully autonomous on the happy path — no prompts, no option menus, no compound decisions. $ARGUMENTS --- ## Step 1 — Resolve AIHAUS_HOME Locate the central aihaus clone. Check in order: 1. `$AIHAUS_HOME` env var — if set and `$AIHAUS_HOME/pkg/.aihaus/skills` exists, use it. 2. `~/.aihaus/.install-source` registry — if the file exists and the recorded path contains `pkg/.aihaus/skills`, use it. 3. Standard candidate paths (newest HEAD commit timestamp wins when multiple match): - `$XDG_DATA_HOME/aihaus` (default: `~/.local/share/aihaus`) - `~/tools/aihaus` - `~/Documents/GitHub/aihaus-flow` - `~/Documents/GitHub/aihaus` - `~/code/aihaus` If no candidate is found, stop with: > "AIHAUS_HOME not found. Clone aihaus (e.g. `git clone https://github.com/user/aihaus ~/tools/aihaus`) then re-run `/aih-install`." The full discovery chain (including tier arbitration) is implemented in `install.sh` itself — the dispatch in Step 3 benefits from it automatically. The check above is the pre-flight guard for the dogfood detection in Step 2. --- ## Step 2 — Detect dogfood mode If both of the following are true in `$PWD`: - `pkg/scripts/install.sh` exists - `pkg/.aihaus/skills/` exists Then `$PWD` IS the central aihaus clone (dogfood mode). Do NOT install into itself. Print: > "Dogfood mode detected — cwd is the aihau
