CHANGELOG.md

@@ -5,6 +5,7 @@
 ### Changes
 - Docs: clarify per-agent auth stores, sandboxed skill binaries, and elevated semantics.
 - Docs: add FAQ entries for missing provider auth after adding agents and Gemini thinking signature errors.
+- Agents: add optional auth-profile copy prompt on `agents add` and improve auth error messaging.
 - Security: add `clawdbot security audit` (`--deep`, `--fix`) and surface it in `status --all` and `doctor`.
 - Onboarding: add a security checkpoint prompt (docs link + sandboxing hint); require `--accept-risk` for `--non-interactive`.
 - Docs: expand gateway security hardening guidance and incident response checklist.
