@@ -39,6 +39,7 @@ Docs: https://docs.openclaw.ai
 - Discord: optimize reaction notification handling to skip unnecessary message fetches in `off`/`all`/`allowlist` modes, streamline reaction routing, and improve reaction emoji formatting. (#18248) Thanks @thewilloftheshadow and @victorGPT.
 - CLI/Pairing: make `openclaw qr --remote` prefer `gateway.remote.url` over tailscale/public URL resolution and register the `openclaw clawbot qr` legacy alias path. (#18091)
 - CLI/QR: restore fail-fast validation for `openclaw qr --remote` when neither `gateway.remote.url` nor tailscale `serve`/`funnel` is configured, preventing unusable remote pairing QR flows. (#18166) Thanks @mbelinky.
+- Auto-reply/Subagents: propagate group context (`groupId`, `groupChannel`, `space`) when spawning via `/subagents spawn`, matching tool-triggered subagent spawn behavior.
 - Agents/Tools/exec: add a preflight guard that detects likely shell env var injection (e.g. `$DM_JSON`, `$TMPDIR`) in Python/Node scripts before execution, preventing recurring cron failures and wasted tokens when models emit mixed shell+language source. (#12836)
 - Agents/Tools: make loop detection progress-aware and phased by hard-blocking known `process(action=poll|log)` no-progress loops, warning on generic identical-call repeats, warning + no-progress-blocking ping-pong alternation loops (10/20), coalescing repeated warning spam into threshold buckets (including canonical ping-pong pairs), adding a global circuit breaker at 30 no-progress repeats, and emitting structured diagnostic `tool.loop` warning/error events for loop actions. (#16808) Thanks @akramcodez and @beca-oc.
 - Agents/Tools: scope the `message` tool schema to the active channel so Telegram uses `buttons` and Discord uses `components`. (#18215) Thanks @obviyus.
