**Summary:** 77 tools total — 27 available in Dev mode, 50 Full-only.
Notes:
- Dev mode focuses on developer workflows (builds, tests, logs) and excludes infrastructure/admin tools to reduce context size (~4-5k tokens saved).
- Admin tools (agents, VCS roots, users, compatibility checks) require Full mode.
