# Data Department Agent Skills — routing index

Read this to pick a skill and narrow to a task group. Then open that skill's SKILL.md and

the one catalog shard you need — never the whole catalog. Selection is by primary

deliverable, not by job title: the work standing in front of the request decides the owner,

not the noun the request ends with.

Ambiguous, multi-role, or a request to resume or hand over work goes to

`data-department-orchestrator` first.
