 ### Fixes
 
+- Pi embedded runs: pass real built-in tools into Pi session creation and then narrow active tool names after custom tool registration, so the runner and compaction paths compile cleanly and keep OpenClaw-managed custom tool allowlists without feeding string arrays into `createAgentSession`. Thanks @vincentkoc.
 - Agents/OpenAI websocket: route native OpenAI websocket metadata and session-header decisions through the shared endpoint classifier so local mocks and custom `models.providers.openai.baseUrl` endpoints stay out of the native OpenAI path consistently across embedded-runner and websocket transport code. Thanks @vincentkoc.
 - Discord: normalize prefixed channel targets only at the thread-binding API boundary, so `sessions_spawn({ runtime: "acp", thread: true })` can create child threads from Discord channels without breaking current-channel ACP bindings. (#68034) Thanks @Zetarcos.
 - Discord: harden inbound thread metadata handling against partial Carbon channel getters, so non-command thread messages and queued jobs no longer crash when `name`, `parentId`, `parent`, or `ownerId` requires fetched raw data.
