@@ -112,6 +112,7 @@ Docs: https://docs.openclaw.ai
 - Agents/fallback: recognize Venice `402 Insufficient USD or Diem balance` billing errors so configured model fallbacks trigger instead of surfacing the raw provider error. (#43205) Thanks @Squabble9.
 - Dependencies: refresh workspace dependencies except the pinned Carbon package, and harden ACP session-config writes against non-string SDK values so newer ACP clients fail fast instead of tripping type/runtime mismatches.
 - Gateway/config errors: surface up to three validation issues in top-level `config.set`, `config.patch`, and `config.apply` error messages while preserving structured issue details. (#42664) Thanks @huntharo.
+- Hooks/plugin context parity followup: pass `trigger` and `channelId` through embedded `llm_input`, `agent_end`, and `llm_output` hook contexts so plugins receive the same agent metadata across hook phases. (#42362) Thanks @zhoulf1006.
