+prompt = """Requested level: {{args}}.

+Resolve the level:
+- Empty → "full" (the documented default)
+- Aliases: "stop", "disable", "persist-off" → "off"; "on", "enable" → "full"; "wenyan" → "wenyan-full"
+- Valid levels: off, lite, full, ultra, wenyan-lite, wenyan-full, wenyan-ultra. Anything else: tell the user the valid set and stop.
+
+Write the resolved level to the caveman config file so the choice persists across sessions:
+
+- macOS/Linux: `~/.config/caveman/config.json` (or `$XDG_CONFIG_HOME/caveman/config.json` if set)
+- Windows: `%APPDATA%\\caveman\\config.json`
+
+Create the parent directory if missing. Read any existing JSON from that path first; merge `{"defaultMode": "<level>"}` into it (do not clobber other fields). Write the result back.
+
+Then act on the new level for this session:
+- If level is "off": return to normal Claude voice for the rest of this session and every future session — the SessionStart hook reads `defaultMode` and skips activation.
+- Otherwise: respond terse like smart caveman at the requested intensity — drop articles, filler, pleasantries. Fragments OK. Technical terms exact. Code unchanged. Pattern: [thing] [action] [reason]. [next step]. The intensity definitions live in SKILL.md.
+
+Persistence is symmetric: `/caveman off` persistently disables, `/caveman <level>` persistently sets that level. To clear the persistent choice entirely and fall back to the built-in default, delete the config file."""

+`/caveman <level>` persists across sessions: it writes `{"defaultMode": "<level>"}` to the caveman config file (`~/.config/caveman/config.json`, or `%APPDATA%\caveman\config.json` on Windows). The SessionStart hook reads this on every resume and applies the saved level — including `off`, which makes the hook skip activation entirely. Symmetric: `/caveman off` persists off, `/caveman full` persists full, etc. To clear the saved choice and fall back to the built-in default of `full`, delete the config file.
