Each tool is one thing Claude can do (read = safe lookup, write = changes data). Most are added for you - from a template, or by importing a system's API spec on its connection. Building one by hand is an advanced fallback.

A group is a named set of tools. Assign people to groups to grant access.

Staff never visit this page - they connect Claude and sign in there. They appear here automatically, marked Pending until you tick a group. Once you do, their tools show up in Claude on their own; no reconnect needed. Revoke ends their sessions now.

Helix is a shared knowledge pool every connected worker can search, read, and contribute to from Claude - a place to capture things people learn. Entries publish immediately; you can edit or remove any of them here.

Skills are installable bundles (a SKILL.md plus optional files) that workers add to their own Claude. Workers can contribute from Claude; submissions wait here for your approval. Access is granted per group (on the Groups tab), and a skill installs to its scope - project, personal, terminal, or Claude Desktop.
