Site Selection Canvas

site_selection_canvas
Read-onlyIdempotent

Input capacity, geography, and deadline to receive a ranked shortlist of US markets with power headroom, time-to-power, and build verdicts. Answer where to build data-center capacity on schedule.

Instructions

Guided end-to-end data-center site selection. Give a capacity target + geography + deadline and get a ranked shortlist of US markets (DCPI verdict, excess-power headroom, time-to-power, ISO) — and, with a paid key, the synthesis decision layer: the #1 pick, the why, a build sequence, and risk flags. One find->rank->shortlist->verdict call over the DC Hub Power Index. Answers "where should I build 100 MW in Texas by 2028". Try: site_selection_canvas capacity_mw=100 region=TX max_months=24. Do NOT use for a single known parcel (use analyze_site) or an open-ended where-should-I-build question (use get_dchub_recommendation); this runs the full find to rank to shortlist to verdict flow.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
isoNoISO/RTO code, e.g. ERCOT or PJM — alias for `region`. Use either; `region` wins if both are sent.
limitNoNumber of shortlist markets to return
stateNoUS state code, e.g. OH — alias for `region`. Use either; `region` wins if both are sent.
regionNoGeography scope: a US state code like TX, an ISO like ERCOT, or a region like us/apac. `state` and `iso` are accepted as aliases for this same filter.
verdictNoOptional DCPI verdict filter: BUILD, CAUTION, or AVOID — or ALL to see every scored market in the geography. Defaults to BUILD,CAUTION, so a geography whose markets are all AVOID returns matched:0 plus an `empty_result` block explaining that; re-run with verdict=ALL to see those rows.
max_monthsNoMaximum acceptable time-to-power in months, 1-120, e.g. 24
capacity_mwNoTarget power load for the build in megawatts (MW), 1-5000, e.g. 100

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
quotaNoCaller quota state (remaining calls, tier) when available.
_entityNoPayload class discriminator (e.g. facility|market|iso_grid|queue_results|deal|report|response) — branch on this before parsing the rest.
citationNoMachine-readable citation: how to attribute DC Hub (dchub.cloud) for this payload. Normally an OBJECT {source, url, license, cite_as, retrieved_at}; a bare string is accepted and carries the attribution line itself.
provenanceNoCollection-level provenance block: {source, method, as_of, verification_counts, cite_url_template, license, cite_as}. Quote the verification level when citing.
_front_doorNoIn-band front-door hint (first workflow-entry tool of a session): call plan_query(intent) first for the ordered multi-step plan.
_return_loopNoSuggested next-session delta call (get_changes since=24h) so you pull only what changed.
site_evaluation_handoffNoPre-built follow-up calls (analyze_site / get_water_risk args) when the payload carries coordinates — an array of {tool, parameters, why} entries.

TDQS

A4.9/5.0
Behavior5/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false; the description goes well beyond this by disclosing the paid-key gating of the synthesis decision layer, the one-call find-to-verdict flow, and the default verdict behavior when markets are all AVOID. It also names the output fields an agent should expect, which is valuable behavioral context.

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

Conciseness5/5

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

The description is dense but efficient: it states the outcome, lists output components, gives an example, and provides explicit exclusions—all in a few sentences. Every sentence earns its place; no filler or redundant restating of the tool name.

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?

Given the tool's complexity, the output schema, and the rich sibling context, the description is complete. It conveys the intended workflow, output composition, paid-tier limitation, and routing guidance, while the schema covers parameter details. An agent has everything needed to select and call this tool correctly.

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 description coverage is 100%, so the baseline is 3. The description adds value by mapping high-level inputs ('capacity target + geography + deadline') to specific parameters and providing a concrete example with realistic values. This lifts it above mere schema repetition, though the schema still does most of the parameter-documentation work.

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 opens with a specific verb and resource: 'Guided end-to-end data-center site selection.' It enumerates concrete outputs (ranked shortlist, DCPI verdict, excess-power headroom, time-to-power, ISO, paid synthesis layer) and immediately distinguishes itself from sibling tools by naming analyze_site and get_dchub_recommendation. There is no ambiguity about what this tool does.

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?

The description gives an explicit 'Do NOT use for...' section with named alternatives and the exact condition for each exclusion. It also provides a runnable example invocation (capacity_mw=100 region=TX max_months=24), making it clear when and how to use this tool versus alternatives.

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