Greptile Summary

This PR adds "auto" as a new value in AgentPermissionMode, wiring it to Claude Code's --permission-mode auto CLI flag so users can opt into the classifier-driven permission model instead of --dangerously-skip-permissions. All four layers of the change — the canonical type, both Zod validation schemas, the plugin's launch and restore command builders, and the config-instruction comment — are updated consistently.

• packages/core/src/types.ts / config.ts / global-config.ts: "auto" is added to AgentPermissionMode, normalizeAgentPermissionMode, AgentPermissionSchema, RoleAgentSpecificConfigSchema, and LocalProjectConfigSchema in lock-step, preserving existing default/transform behavior for all other values.
• packages/plugins/agent-claude-code/src/index.ts: Both getLaunchCommand and getRestoreCommand gain an else if (permissionMode === "auto") branch emitting --permission-mode auto; new Vitest tests cover both paths.

Confidence Score: 5/5

Safe to merge — the change is narrowly scoped to adding a new opt-in permission mode with no modifications to existing paths.

All four layers of the abstraction (canonical type, both Zod schemas, the plugin command builders, and the config comment) are updated consistently and in lock-step. The new auto branch in getLaunchCommand and getRestoreCommand is strictly additive — existing permissionless, auto-edit, default, and suggest branches are untouched. Vitest tests assert the correct CLI flag is emitted and that --dangerously-skip-permissions is absent for the new mode, covering both the launch and restore code paths.

No files require special attention.
