The two tools have clearly distinct purposes: `codex` initiates a new autonomous task and returns a thread_id, while `codex_reply` explicitly requires that thread_id to continue an existing conversation. No functional overlap exists.

Both tools share the `codex` prefix which groups them logically, and `codex_reply` clearly indicates its action. However, the base tool `codex` lacks a descriptive action verb (e.g., `codex_send` or `codex_start`) despite its description emphasizing sending tasks, creating a minor inconsistency in the naming pattern.

With only 2 tools, the set is borderline thin for a server claiming to handle 'complex software engineering tasks end-to-end.' While the initiate-respond loop is functional, the lack of supporting operations (list threads, check status, cancel) makes the surface feel constrained rather than comprehensively scoped.

The core conversational workflow is covered (start thread, continue thread), but significant lifecycle operations are missing: there is no way to list active threads, retrieve thread history without continuing, cancel running tasks, or delete threads. These gaps limit agent ability to manage long-running or parallel autonomous tasks.
