DC Hub: Data Center, Power Grid & Energy Intelligence

Unlock More Data

unlock_more_data

Get access options with links to view full, non-preview DC Hub data center results. Returns plans and checkout details showing whether the next call returns complete data.

Instructions

Use this when the user asks how to get full (non-preview) DC Hub data center results. Returns the access options with links for the user to open. If this call carries an API key or an MCP session, the checkout binds to it and your very next call returns full data (no reconnect); if it carries neither, the key is emailed to the payer instead — the response says which applies in next_call_full_after_checkout and after_checkout. Paid plans: on the page behind the human_url link. Want the FREE tier instead (no payment, previews plus 2 full answers per tool per day, 50/day with an email)? Call claim_free_key. A gated result already carries its link in human_url; that link is the one to share, and this tool returns the fuller ladder. Param: reason (optional — what you were trying to do, so your human sees why it matters). Returns {plans, human_message, what_unlocks}.

TDQS

A4.6/5.0

Behavior5/5

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

Annotations declare non-read-only and non-idempotent but say nothing about why; the description fills that gap by explaining the checkout binding (API key or MCP session -> next call returns full data) versus the emailed-key fallback, and names the response fields that report which case applies. That is exactly the beyond-annotation context needed for a paid-unlock tool.

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?

Trigger and behavior are front-loaded, and each sentence carries routing or side-effect information. It is denser than necessary with stacked parentheticals, but almost no sentence is purely filler.

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, so return-value explanation is not required, and the description still notes which response fields matter. Usage, alternatives, and the post-checkout side effect are all covered for a one-param tool.

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?

There is only one optional param with 100% schema description coverage, so the schema already documents it fully. The description's 'reason (optional — what you were trying to do, so your human sees why it matters)' largely restates the schema rather than adding new syntax or format meaning.

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 opening sentence states a specific trigger and outcome: full (non-preview) DC Hub results, returning access options with links. It clearly separates itself from the free-tier sibling claim_free_key without the agent needing to open 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?

Explicit when-to-use ('when the user asks how to get full (non-preview) data'), explicit alternative with its own trigger ('Want the FREE tier instead... Call claim_free_key'), and guidance on when a human_url link is already sufficient. Nothing 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.
