DC Hub: Data Center, Power Grid & Energy Intelligence

Generate Site Analysis

generate_site_analysis

Read-onlyIdempotent

Generate a branded, shareable Site Analysis PDF for one parcel or candidate campus, covering power, water, fiber, latency, and permitting for a target MW load.

Instructions

Use this when the user wants a shareable data center Site Analysis PDF for ONE lat/lon (a powered-land parcel, a candidate campus) — the polished client deliverable, not just a score. Example: "Make the Site Analysis PDF for this Carrier Mills parcel, 150 MW, for TON Infrastructure." — generate_site_analysis lat=37.694 lon=-88.65 capacity_mw=150 prepared_for="TON Infrastructure" prepared_by="Martone Advisors". Params: lat (-90 to 90, required), lon (-180 to 180, required), capacity_mw (target load MW, e.g. 50-500), prepared_for (client name on the cover), prepared_by (your firm — brands the report; defaults to DC Hub), latency_target (optional metro override; default = nearest real carrier hotel). Returns: {survey:{verdict, power/transmission, gas, water, air-permitting, fiber carriers, latency-to-nearest-carrier-hotel, market, tax}, pdf_report_url}. pdf_report_url is a ready-to-open link to download the branded 5-page PDF — no login needed, valid ~7 days; hand it to your human. For just the numeric suitability score (no PDF), use analyze_site instead.

Input Schema

TDQS

A4.5/5.0

Behavior4/5

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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive), and the description adds real operational context: a branded 5-page PDF, a link that needs no login, and a ~7-day validity window that the agent must relay to its human. It stops short of describing error behavior or what happens when a coordinate falls outside coverage.

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-loaded with the trigger and the sibling exclusion, then the example, then the param recap — a sensible order with no wasted preamble. The trailing 'Params:' block largely duplicates a fully-covered schema and could be trimmed.

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?

Output schema exists, yet the description still usefully sketches the return shape and calls out pdf_report_url as the actionable artifact, which is what the agent must hand back. Gaps: use_case is never mentioned, and the description insists lat/lon are 'required' while the schema declares zero required parameters — a mismatch that could cause the agent to demand a coordinate the schema treats as optional.

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 earns one more by pairing each core parameter with a realistic value in the worked example (lat=37.694 lon=-88.65 capacity_mw=150) and reinforcing defaults for prepared_by and latency_target. It omits use_case entirely and repeats range/default facts the schema already states, so it stays below a 5.

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 (generate a shareable Site Analysis PDF) scoped to exactly one lat/lon parcel, and explicitly frames it as 'the polished client deliverable, not just a score.' It names the sibling it is not (analyze_site) so the agent can disambiguate without opening 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?

Gives an explicit trigger ('use this when the user wants a shareable ... PDF for ONE lat/lon'), a concrete worked example with realistic argument values, and a stated when-not ('For just the numeric suitability score (no PDF), use analyze_site instead'). Nothing about selection 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.
