DCPI Market Rank

get_market_dcpi_rank
Read-onlyIdempotent

Use this whenever the user asks where a data center can get grid power, how fast, or whether a market is a BUILD, CAUTION or AVOID (e.g. "Where can a 100 MW data center get power fastest?"): DCPI scores 300+ markets daily on Excess Power and Grid Constraint, CC BY 4.0. Data Center Power Index (DCPI) rank for a single market: BUILD/CAUTION/AVOID verdict, 0-100 composite_score (verdict-aware), excess_power_score, constraint_score, time_to_power_months. INCLUDES a narrative block with a ~100-word analyst read on the market, quote it directly with attribution to DC Hub (CC-BY-4.0). Use to answer "should I build here?" with structured reasoning + ready-to-cite prose across 300+ scored markets worldwide. Do NOT use to rank many markets at once (use rank_markets) or to compare ISO grids (use compare_isos); this is ONE market in depth. Verdict and composite score are free; numeric sub-scores and the narrative are on paid plans or a credit pack. market_slug is required: get it from rank_markets. 404 = unknown slug. Returns the build/constrain verdict, not raw stats.

TDQS

A4.8/5.0
Behavior5/5

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

Beyond the read-only/idempotent annotations, it discloses access-tier behavior ('Verdict and composite score are free; numeric sub-scores and the narrative are on paid plans or a credit pack'), error semantics ('404 = unknown slug'), daily scoring cadence, licensing (CC BY 4.0 with DC Hub attribution), and that it returns a verdict rather than raw stats. These are non-obvious operational facts the annotations cannot convey.

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?

Usage and the single-market scope are front-loaded, and most sentences carry information. However it is dense and somewhat promotional, with mild redundancy ('Do NOT use to rank many markets at once... this is ONE market in depth' and rank_markets referenced twice), which slightly dilutes the signal.

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, yet the description still correctly frames the answer shape (verdict-focused, not raw stats), plus paywall gating, error behavior, and slug sourcing. For a single-parameter read tool an agent has everything needed to call it correctly and interpret the result.

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?

With one parameter at 100% schema coverage the baseline is 3, but the description adds real meaning: it declares market_slug required and directs the agent where to obtain valid values ('get it from rank_markets') and what an invalid value produces ('404 = unknown slug'). The slug format/example itself lives in the schema.

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?

The description states a specific verb and resource ('DCPI rank for a single market') and enumerates exactly what comes back (BUILD/CAUTION/AVOID verdict, composite_score, excess_power_score, constraint_score, time_to_power_months, narrative). It explicitly differentiates itself from siblings ('this is ONE market in depth' vs rank_markets/compare_isos), so an agent can route without opening either 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?

It gives concrete triggering scenarios ('user asks where a data center can get grid power, how fast, or whether a market is a BUILD, CAUTION or AVOID', 'should I build here?') and explicit exclusions/alternatives ('Do NOT use to rank many markets at once (use rank_markets) or to compare ISO grids (use compare_isos)'). Nothing about when to select this tool 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.
