Scored across 9 tools
Each tool has a clearly distinct purpose: creating, counter-signing, verifying, admitting, and generating identities. No two tools overlap in functionality.
All tool names consistently use the verb_noun pattern with underscores (e.g., create_exit_marker, verify_and_admit), making the set predictable and easy to navigate.
With 9 tools covering the core workflows of creating, verifying, admitting, and transferring EXIT markers, the count is well-scoped and each tool earns its place.
The tool set covers the main lifecycle: creation, verification, admission, and transfer. Minor gaps exist, such as no tool to manage admission policies beyond listing, but the core functionality is complete.
