 - ✅ F-003 addressed: tool execution now has an `AbortSignal` contract, executor triggers abort on timeout, high-risk tools (`shell.exec`, sandbox docker exec, `process.start`, browser tools, `web.fetch`, `web.search`) respond to cancellation, and executor regression tests verify cancellable tools do not apply side effects after timeout.
 - ✅ F-015 addressed: retry defaults no longer classify timeout-style failures as non-retryable, improving resilience for transient timeout conditions.
 - ✅ F-011 addressed: Slack user-name resolution now uses bounded TTL+LRU caching to prevent unbounded growth.
+- ◑ F-013 partially addressed: reset-command normalization is now shared across Discord/Slack/WhatsApp adapters via `src/channels/utils.ts`, reducing duplicated command-parsing logic.
 
 ## Executive Summary
