CHANGELOG.md

@@ -53,6 +53,7 @@ Docs: https://docs.openclaw.ai
 - Agents: keep unresolved mutating tool failures visible until the same action retry succeeds, scope mutation-error surfacing to mutating calls (including `session_status` model changes), and dedupe duplicate failure warnings in outbound replies. (#16131) Thanks @Swader.
 - Agents/Workspace: create `BOOTSTRAP.md` when core workspace files are seeded in partially initialized workspaces, while keeping BOOTSTRAP one-shot after onboarding deletion. (#16457) Thanks @robbyczgw-cla.
 - Agents: classify external timeout aborts during compaction the same as internal timeouts, preventing unnecessary auth-profile rotation and preserving compaction-timeout snapshot fallback behavior. (#9855) Thanks @mverrilli.
+- Agents: treat empty-stream provider failures (`request ended without sending any chunks`) as timeout-class failover signals, enabling auth-profile rotation/fallback and showing a friendly timeout message instead of raw provider errors. (#10210) Thanks @zenchantlive.
 - Ollama/Agents: avoid forcing `<final>` tag enforcement for Ollama models, which could suppress all output as `(no output)`. (#16191) Thanks @Glucksberg.
 - Plugins: suppress false duplicate plugin id warnings when the same extension is discovered via multiple paths (config/workspace/global vs bundled), while still warning on genuine duplicates. (#16222) Thanks @shadril238.
 - Skills: watch `SKILL.md` only when refreshing skills snapshot to avoid file-descriptor exhaustion in large data trees. (#11325) Thanks @household-bard.
