Gas Index (DCGI)

get_gas_index
Read-onlyIdempotent

Score US states for gas-fired data center power suitability with the Data Center Gas Index, returning each state’s DCGI score, verdict, and pricing series; unscored states are flagged clearly.

Instructions

Use this when the user asks which US states suit gas-fired data center power: the Data Center Gas Index (DCGI), a per-state score. ★ DO NOT COMPARE a DCGI figure published before 2026-08-08 with one published now — they are different indices; the full record is at /api/v1/dcgi/methodology under corrections. A state that cannot be priced comes back verdict UNSCORED with dcgi null and an unscored_reason, never a placeholder score, so treat UNSCORED as absence and not as a low score. gas_price_series names which EIA series answered each state. Gas-fired $/MWh figures, withdrawn the same day for a separate defect, were republished 2026-09-27 under one burner-tip price rule (see get_gas_economics). Use get_gas_intelligence for pipeline, operator and parent-midstream data.

  8. First observedv2.1.19

TDQS

A4.6/5.0
Behavior5/5

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

Annotations already declare a safe, idempotent read, so the bar is low, yet the description adds substantial behavioral context: the index-versioning hazard (differing DCGI figures before/after 2026-08-08), where the full methodology record lives, and the UNSCORED-not-low-score semantics. It also explains that gas_price_series identifies which EIA series priced each state.

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-loads the core purpose before the caveats, and most sentences (UNSCORED semantics, version warning, sibling routing) earn their place. It is somewhat packed with dated incident detail (same-day withdrawal, 2026-09-27 republish) that could be tightened, but it remains readable.

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?

With an output schema present, return values need not be re-explained, and the description still covers the two things an agent must not get wrong: cross-version comparability and treating UNSCORED as absence. Alternatives and the methodology endpoint are also supplied.

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

Parameters3/5

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

Schema description coverage is 100%, so both parameters (limit, state) are already fully documented, which sets the baseline at 3. The description adds semantics around state output (verdict, gas_price_series) but nothing new about parameter syntax or constraints beyond 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?

States a specific verb+resource+scope: 'which US states suit gas-fired data center power' scored per-state by the Data Center Gas Index (DCGI). It is clearly distinguishable from sibling gas tools, naming get_gas_intelligence (pipeline/operator/midstream) and get_gas_economics as the alternatives.

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 ('Use this when the user asks which US states suit gas-fired data center power') and explicit routing away from siblings ('Use get_gas_intelligence for pipeline, operator and parent-midstream data'), plus a reference to get_gas_economics. When-to-use and when-to-use-something-else are both covered.

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