  • Allows per-agent override of Claude Code settings via new settings field
  • Settings apply at flag tier (highest priority except managed policy)
  • Works on both SDK and CLI runtimes
  • Particularly useful for settings like autoMemoryDirectory that Claude Code ignores in project settings files

Keep the entries in the rolling log until it nears the archive threshold.

The 2026-10-07 entry records about 2,100 tokens. The next entry says it archived February–March entries and reduced the log to about 1,200 tokens. Restore those entries to agents/engineer/conversations.md and remove or update the premature archive metadata in agents/engineer/conversations-archive.md.

As per coding guidelines, “Check conversations.md size and archive older entries if approaching ~20,000 tokens.”

Document the non-loopback exposure and require authentication.

fleet.web.host defaults to localhost, but operators can configure another host. The configured value is passed directly to Fastify. The chat session routes and other API routes have no authentication hook. A non-loopback bind can therefore expose session data and state-changing endpoints to the network.

Update both recommendations to require authentication or to prohibit non-loopback binds until authentication exists.

Suggested report update

-   - Add warning against binding to `0.0.0.0`
-   - Clarify localhost-only design intent
+   - Keep the default bind on `localhost`
+   - Warn that non-loopback binds expose an unauthenticated API
+   - Require authentication and appropriate transport/access controls for remote access, or prohibit non-loopback binds

Apply the same change to agents/security/summaries/2026-10-09-summary.md.

Use a consistent commit count and classification in both reports.

The reports claim three code or substantive commits, but their breakdowns name the settings change and version bump, then classify 19 housekeeping commits as containing no code changes. Reconcile the counts against the analyzed commits.

• agents/security/intel/2026-10-12.md#L28-L28: Correct the production-code count or list the missing commit.
