Get Gas Intelligence

get_gas_intelligence
Read-onlyIdempotent

Use this whenever the user asks about gas-fired or behind-the-meter power for a data center in a US state. Use when a human asks about gas-fired or behind-the-meter power economics for a data center in a US state — "is gas power cheaper than the grid in Texas?", "what is the gas access + pipeline situation in Virginia?". The GAS analogue of get_grid_intelligence: fuses the Data Center Gas Index (DCGI), live Henry Hub, gas-to-grid $/MWh across heat-rate scenarios, pipeline-operator presence, and the live grid gas share into one per-STATE brief. Params: region (US state code or name, e.g. "TX" | "Texas" | "Virginia"). Returns: {region, region_name, gas_access (pipeline counts + operators — PRESENCE not firm capacity), henry_hub_usd_mmbtu (live), basis_usd_mmbtu (synthetic-labeled), delivered_price_usd_mmbtu (null where the tariff table is sparse — surfaced honestly, never fabricated), live_grid_gas_share_pct, pipeline_presence (operators + parent midstreams), data_basis (per-field provenance/confidence), omitted_no_fabrication, dcgi_status, gas_to_grid_status}. ★ ★ TWO DIFFERENT STATES, do not merge them. dcgi_score and dcgi_verdict were withdrawn 2026-08-08 and RESTORED 2026-08-30 once all three defective terms were repaired — they are returned again, but a figure published before 2026-08-08 is from a different index and must not be compared with one published now (/api/v1/dcgi/methodology corrections). gas_to_grid_usd_per_mwh and the behind-the-meter-vs-grid delta were WITHDRAWN 2026-08-08 and RESTORED 2026-09-27 under one burner-tip price rule (EIA electric-power gas, trailing-12-month mean; burner_tip carries the price, window and — for a state EIA withholds — the reason the $/MWh is null). A $/MWh published before 2026-09-27 is not comparable. dcgi_status and gas_to_grid_status carry the current state of each — read them rather than assuming both moved together. DO NOT quote a DCGI score cached before 2026-08-30 or a $/MWh cached before 2026-09-27. Everything else in this brief — live Henry Hub, live ISO gas share, pipeline and parent-midstream presence — is unaffected and is what this tool is now for. Every field carries a data_basis label; gas storage / LNG / firm pipeline capacity are deliberately OMITTED (no feed). Do NOT use for electricity grid headroom (use get_grid_intelligence) or the DCGI score alone (use get_gas_index).

TDQS

A4.4/5.0
Behavior5/5

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

Annotations already declare readOnly/openWorld/idempotent/non-destructive, so the bar is low, yet the description goes well beyond: synthetic-labeled basis, null delivered prices 'surfaced honestly, never fabricated', deliberately omitted feeds (gas storage/LNG/firm capacity), per-field data_basis provenance, and dated withdrawal/restoration caveats on dcgi_score and gas_to_grid_usd_per_mwh. These are real behavioral traits (data comparability, caching hazards) an agent cannot get from annotations.

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

Conciseness2/5

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

Usage guidance is front-loaded and well-placed, but the description is grossly oversized: the when-to-use instruction is stated twice in near-identical wording, and a large block of dated withdrawal/restoration history and cache warnings ('DO NOT quote a DCGI score cached before 2026-08-30') crowds out the core signal. Much of that versioning detail belongs in the referenced /api/v1/dcgi/methodology endpoint rather than in a selection-time description.

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?

For a read-only, open-world per-state intelligence brief with an output schema and full annotation coverage, nothing an agent needs to call it correctly is missing: scope, routing, provenance, null-handling and deliberate omissions are all disclosed. The output schema carries the return-shape burden, so the description's completeness is sufficient.

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% and both parameters are documented there, so the schema does the heavy lifting; the baseline is 3. The description restates the region param ('US state code or name, e.g. "TX" | "Texas" | "Virginia"') but never mentions the 'state' alias that exists in the schema, so it adds nothing beyond structured data.

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 names a specific verb+resource ('fuses the Data Center Gas Index, live Henry Hub, gas-to-grid $/MWh, pipeline-operator presence, and live grid gas share into one per-STATE brief') and explicitly positions itself relative to siblings as 'the GAS analogue of get_grid_intelligence.' An agent can distinguish it from get_grid_intelligence and get_gas_index without opening any 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 states when to use ('whenever the user asks about gas-fired or behind-the-meter power for a data center in a US state') with sample phrasings, and gives explicit when-not-to-use routing: 'Do NOT use for electricity grid headroom (use get_grid_intelligence) or the DCGI score alone (use get_gas_index).' Both alternatives are named with the condition that selects them.

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