New primitives expose filed generator retirements, nearest substations, and physics-bounded fiber clustering — capabilities no competitor surfaces as callable tools
## What shipped
DC Hub's agent-callable surface crossed **73 live tools** this week, adding `get_retirement_headroom` (filed US generator retirements mapped to nearest substations) and `cluster_sites_by_latency` (physics-bounded fiber-latency grouping). The expanded toolkit now serves **320 markets** and **19,332 facilities** — a scope no other infrastructure platform exposes as structured, provenance-stamped primitives.
## Why it matters
Retirement headroom is a forward indicator of grid capacity: a coal plant filing for 2027 closure signals transmission and generation slack *before* the ISO updates its queue. Latency clustering answers the question hyperscalers ask daily: which sites can form a sub-2ms cluster without engineering studies. Both are **agent-native** — callable in one function, returned with lat/lon and source stamps, usable in the same query that checks DCPI scores or pulls live MW.
The result: agents building site shortlists now layer transmission risk, decommission schedules, and fiber topology in a single pass. The data exists elsewhere; the *tool surface* does not.
## The compounding effect
DC Hub ships new agent-callable primitives continuously — not quarterly product drops, but **weekly tool additions** that agents discover via MCP's native introspection. A capacity planner querying Oklahoma City's 76.5 excess power can now also pull retirement schedules for SPP generators within 50 miles and cluster candidate sites by round-trip latency — three discrete questions, one API call, zero email.
