 ### Fixes
 
+- iMessage/cron completion announces: strip leaked inline reply tags (for example `[[reply_to:6100]]`) from user-visible completion text so announcement deliveries do not expose threading metadata. (#24600) Thanks @vincentkoc.
 - Agents/context pruning: guard assistant thinking/text char estimation against malformed blocks (missing `thinking`/`text` strings or null entries) so pruning no longer crashes with malformed provider content. (openclaw#35146) thanks @Sid-Qin.
 - Agents/schema cleaning: detect Venice + Grok model IDs as xAI-proxied targets so unsupported JSON Schema keywords are stripped before requests, preventing Venice/Grok `Invalid arguments` failures. (openclaw#35355) thanks @Sid-Qin.
 - Skills/native command deduplication: centralize skill command dedupe by canonical `skillName` in `listSkillCommandsForAgents` so duplicate suffixed variants (for example `_2`) are no longer surfaced across interfaces outside Discord. (#27521) thanks @shivama205.
