DC Hub: Data Center, Power Grid & Energy Intelligence

Market Intelligence Index

get_intelligence_index

Read-onlyIdempotent

Scores data center market health on a 0-100 composite, combining supply, demand, vacancy, absorption, fiber, power and pricing. Returns percentile rank and 7d/30d trend for one market.

Instructions

Use this when the user asks how healthy a data center market is: composite score (0-100) aggregating supply/demand balance, vacancy, absorption velocity, fiber depth, power availability, and pricing trend. Returns the index value, percentile rank across the 300+ market set, 7d/30d trend direction, and underlying component scores. Answers "is this market healthy", "how does Northern Virginia look overall right now". Try: get_intelligence_index market=northern-virginia. Returns ONE composite health number for a market; do NOT use for the full market metric set (use get_market_intel) or to rank multiple markets (use rank_markets).

TDQS

A4.6/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint/idempotentHint/destructiveHint=false, so safety is covered. The description adds genuine context beyond that: the score's composition, its 0-100 range, the 300+ market comparison set, and the 7d/30d trend output. It does not cover rate limits or data freshness/latency, which keeps it from a 5.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the trigger and the return summary, then the routing exclusions. Dense and mostly waste-free, though the long component enumeration and the duplicated 'one composite health number' phrasing cost a little.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return-shape explanation is a bonus rather than a requirement, and the description still sketches the key returns. For a zero-parameter read tool, an agent has everything needed to select and call it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Zero declared parameters, so the baseline is 4. The description supplies a concrete call example ('get_intelligence_index market=northern-virginia'), though this implies a 'market' argument the empty schema does not define, which is a minor inconsistency rather than added semantic depth.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource ('composite score (0-100) aggregating supply/demand balance, vacancy, absorption velocity, fiber depth, power availability, and pricing trend') and explicitly names the siblings it is not (get_market_intel, rank_markets). An agent can distinguish this from the 90+ other 'get_*_intel' tools without opening a schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives an explicit trigger ('when the user asks how healthy a data center market is'), sample utterances it answers, and two named exclusions with the correct alternatives for each (full metric set → get_market_intel; multi-market ranking → rank_markets). Nothing is left to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
