DC Hub: Data Center, Power Grid & Energy Intelligence

Deal Autopsy

deal_autopsy

Read-onlyIdempotent

Assess recent data-center deals for power viability: returns buyer, seller, value, market, DCPI verdict, time-to-power, and an optional per-deal read of power options versus build or queue risk.

Instructions

Use this when the user asks what a data-center deal means for power: deal flow with each market's DCPI verdict — "what is the real play?". Returns recent deals (buyer, seller, value, market) + each market DCPI verdict and time-to-power; with a paid key, the per-deal autopsy read (long-dated land/power option vs near-term build vs queue gamble). Progressive disclosure to keep the default cheap: by default each read ships only a comparables COUNT (the verdict text is always included); pass comparables="summary" for the top-2 grounding signals, or comparables="full" to expand the complete cited set for a deal you're drilling into. Answers "who is actually buying data centers right now, and are those markets any good", "what is the real play behind this deal". Try: deal_autopsy limit=15.

Input Schema

Name	Required	Description	Default
`limit`	No	Number of recent deals to return (default ~15)
`comparables`	No	Comparables detail: "none" (default — count only, cheapest), "summary" (top-2 grounding signals), or "full" (the complete cited set). Escalate only for deals you're drilling into.

TDQS

A3.9/5.0

Behavior4/5

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

Annotations already declare read-only, idempotent, non-destructive, closed-world, so the safety profile is covered. The description adds genuinely non-obvious behavior: the per-deal autopsy read is gated behind a paid key, and the default response is deliberately trimmed (comparables count only) to keep it cheap. No rate limits or failure modes, but the paywall and progressive-disclosure cost model are real added context.

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?

Front-loaded with the trigger condition, which is good. But it is dense and repetitive: the 'what is the real play' framing appears twice, and there are many embedded quoted phrases and dashes that add length without adding information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be spelled out, and the description nonetheless sketches the shape (deal fields + DCPI verdict + time-to-power). Trigger conditions, the paid-key caveat, and the disclosure levels are all present, leaving only minor gaps such as ranking/ordering of the returned deals.

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?

Schema coverage is 100%, so the baseline is 3. The description goes beyond the schema by giving escalation guidance for comparables ('escalate only for deals you're drilling into') and by confirming the verdict text is always included regardless of the comparables setting, which resolves a plausible ambiguity.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a concrete verb and resource: returns recent data-center deals (buyer, seller, value, market) joined to each market's DCPI verdict and time-to-power. An agent can distinguish it from the broader deal listers. It never names a sibling it is not (e.g. hyperscaler_deals, list_transactions), so the differentiation is inferred rather than stated.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicit when-to-use: 'Use this when the user asks what a data-center deal means for power' plus two representative user questions and a worked call example (deal_autopsy limit=15). Clear context, but no when-not-to-use and no named alternative for plain deal listing.

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