 - Doctor: surface plugin diagnostics in the report.
 - Plugins: treat `plugins.load.paths` directory entries as package roots when they contain `package.json` + `clawdbot.extensions`.
 - Config: expand `~` in `CLAWDBOT_CONFIG_PATH` and common path-like config fields (including `plugins.load.paths`).
+- Auto-reply: align `/think` default display with model reasoning defaults. (#751) — thanks @gabriel-trigo.
 - Docker: tolerate unset optional env vars in docker-setup.sh under strict mode. (#725) — thanks @petradonka.
 - CLI/Update: preserve base environment when passing overrides to update subprocesses. (#713) — thanks @danielz1z.
 - Agents: treat message tool errors as failures so fallback replies still send; require `to` + `message` for `action=send`. (#717) — thanks @theglove44.
