Auto Mode auto-disables after Plan Mode cycle (triggered by plan-first skills); documented workaround keys appear ineffective

Summary

Auto Mode is automatically disabled after any Plan Mode enter/exit cycle, even when the cycle is triggered by a skill the user did not invoke. This makes Auto Mode unusable in projects that rely on plan-first skills (e.g. superpowers:using-superpowers).

Reproduction

1. Enable Auto Mode via the UI.
2. Send any message that invokes a slash command or skill which internally calls EnterPlanMode → ExitPlanMode.

• In my environment: a project slash command that just reads memory files triggers this because superpowers:using-superpowers asserts a plan-first flow.

1. Observe:

• System reminder: ## Exited Plan Mode
• System reminder: ## Exited Auto Mode ← Auto Mode silently disabled

1. Further turns require re-enabling Auto Mode manually.

Expected

Auto Mode should persist across Plan Mode cycles unless the user explicitly disables it. At minimum, a supported setting should allow this.

Attempted workarounds (not effective)

Settings I applied in ~/.claude/settings.json:

{
  "useAutoModeDuringPlan": true,
  "skillOverrides": {
    "using-superpowers": "name-only"
  }
}

Neither key appears to be recognized: the using-superpowers skill body is still injected as a full <EXTREMELY_IMPORTANT> block on every session start, and Auto Mode still disables after the plan cycle. I suspect these are not documented/official settings keys — if so, please clarify the correct mechanism (or add one).

Requests

1. Document the official way to:

• (a) persist Auto Mode across Plan Mode cycles
• (b) disable or "name-only" a plugin-managed skill at the settings level

1. Consider making Auto Mode survive Plan Mode cycles by default, since the cycle is often triggered by skills outside the user's explicit control.
