DC Hub: Data Center, Power Grid & Energy Intelligence

Citation Block

summarize_for_citation

Read-onlyIdempotent

Generates a paste-ready attribution line with the correct per-layer licence for citing DC Hub data center or power figures.

Instructions

Use this when you quote a DC Hub data center or power figure: returns one paste-ready attribution line for the value you are about to cite, with the CORRECT licence for that layer. Pass what you read off the response you are citing: subject (what the figure is), as_of (the provenance as_of), url (the row's profile_url or dcpi_url), completeness (the completeness flag), and layer. ★ LICENCE IS PER LAYER AND THIS IS THE POINT: DCPI verdicts and composite scores (CC-BY-4.0 30 days after the day they describe; current values: quote up to five markets per piece, republishing needs a DCPI licence, https://dchub.cloud/terms#dcpi-current-data), band thresholds, methodology and DC Hub's own grid/site analysis (CC-BY-4.0) are yours to quote with attribution; the facility inventory and third-party physical layers are COMPOSITES whose upstream terms DC Hub cannot waive (parts are OpenStreetMap, ODbL 1.0, share-alike), so they carry a pointer to https://dchub.cloud/data-sources instead of a grant. A flat "CC-BY-4.0" over a facility record is an over-claim. Returns {citation_text, cite_as, license, license_basis, source, url, as_of, as_of_basis, completeness, omitted}. Free, no key, no network call — it assembles what you pass and never resolves or invents a value.

Input Schema

Name	Required	Description
`url`	No	The profile_url or dcpi_url from the cited row. Must be a dchub.cloud URL; anything else is dropped and named in `omitted`.
`as_of`	No	The as_of you read off the cited response (provenance.as_of). Omit it and the line says RETRIEVED instead of claiming a data date.
`layer`	No	Which layer the figure came from: dcpi \| grid_analysis \| facility_inventory \| physical_infrastructure \| deals \| other. Decides the licence line; omit and you get the scoped statement rather than a grant.
`subject`	No	What you are citing, in the words you will show the human, e.g. "Ashburn DCPI verdict" or "ERCOT interconnection queue depth"
`completeness`	No	The completeness flag from the cited response, if it carried one

TDQS

A4.5/5.0

Behavior5/5

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

Beyond the annotations (readOnly/idempotent/openWorld=false), it discloses that the call is free, needs no key, makes no network call, and 'never resolves or invents a value' — a critical anti-hallucination guarantee. It also discloses the failure mode (non-dchub.cloud URLs are dropped and named in `omitted`) and the licence-policy rationale for composite layers.

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

Conciseness3/5

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

The trigger is correctly front-loaded, but the body is a single dense run-on packed with parentheticals, two URLs, and a ★ marker. The licence taxonomy is genuinely complex, yet the content could be split into short sentences and the return-field list dropped since an output schema exists.

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 zero-required-parameter assembly utility, the description covers the trigger, the provenance chain for each input, the licence decision rules per layer, and the degradation behavior when inputs are missing or invalid. Nothing an agent needs to call it correctly is absent.

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 coverage is 100%, so the schema already documents all five parameters including the omission consequences for `as_of` and `layer`. The description adds the workflow framing ('pass what you read off the response you are citing') but largely restates what the schema says, so the baseline of 3 applies.

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 artifact: it returns one paste-ready attribution line with the correct per-layer licence for a figure you are about to cite. No sibling tool in the list does citation assembly, and the description makes that role unmistakable within the first clause.

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?

'Use this when you quote a DC Hub data center or power figure' gives an explicit trigger, and the warning that 'a flat CC-BY-4.0 over a facility record is an over-claim' tells the agent what not to do instead. The call-site inputs are also enumerated, so the agent knows what to gather before invoking.

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