DC Hub: Data Center, Power Grid & Energy Intelligence

Market Intelligence

get_market_intel
Read-onlyIdempotent

Retrieves detailed data-center market statistics like facility counts, operators, pipeline status, and lease pricing for a specific metro to support siting and investment analysis.

Instructions

Use this when the user asks about a data-center market (metro supply, operators, pipeline, pricing): facility count, tracked MW, status mix, top providers, recent facilities or lease pricing. Pass market as a slug (e.g. northern-virginia). Returns stats, by_status, top_providers, recent_facilities, market_pricing (quote its basis). Verdict: use get_market_dcpi_rank. Keyless: a trimmed preview; a free key gets more. Ex: "1 MW colo price in Los Angeles?" Get the market slug from rank_markets or get_market_dcpi_rank; 404 = unrecognised market, use one of those slugs.

Input Schema

metricNoOptional single metric to focus on, e.g. vacancy, pricing, absorption, pipeline
periodNoOptional time window for the metric, e.g. ttm, 12mo, ytd
compare_toNoOptional second market slug to compare against, e.g. dallas

TDQS

A4.6/5.0
Behavior4/5

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

Annotations already establish read-only, idempotent, non-destructive behavior. The description adds useful runtime context beyond annotations: keyless access returns a trimmed preview, a free key unlocks more, 404 means unrecognized market, and market_pricing should be quoted with its basis. It does not cover rate limits or full response shape, but it is substantially more informative than the annotations alone.

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?

The description is front-loaded with the primary use case and compactly covers return fields, alternatives, auth behavior, examples, and slug sourcing. It is information-dense and fragmentary in places, but nearly every clause earns its place.

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?

Given an output schema, rich annotations, and four optional parameters, the description provides everything needed to select and invoke the tool correctly: use case, slug sourcing, return fields, keyless limitation, error handling, and the sibling to use for verdicts.

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?

Schema description coverage is 100%, so the baseline is 3. The description adds practical meaning by reinforcing the market slug format, giving an example, and telling the agent where to obtain valid slugs. It does not add much detail for metric, period, or compare_to beyond the schema, but the slug guidance is valuable.

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 and resource: market intelligence for data-center markets, with concrete coverage areas such as metro supply, operators, pipeline, pricing, facility count, tracked MW, status mix, top providers, and recent facilities. It also names sibling tools for adjacent needs, so an agent can distinguish it from get_market_dcpi_rank and rank_markets.

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?

Explicitly says when to use it: when the user asks about a data-center market. It also gives the required slug form, points to rank_markets or get_market_dcpi_rank for valid slugs, explains 404 behavior, and routes verdict requests to get_market_dcpi_rank.

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