Save To Shortlist

save_to_shortlist

Save a data center site to a persistent named shortlist, snapshotting its objectives and score so you can re-score it later against evolving national baselines.

Instructions

Use this when the user wants to keep a data center site on a named shortlist that survives across conversations (Phase 5 statefulness). Snapshots the site's objectives + its current percentile objective_score, so you can re-score it later against the evolving national baseline. Use to build a durable siting shortlist across days/weeks; the list is scoped to your API key. Pair with get_shortlist to re-score + see drift. MINIMAL call: save_to_shortlist(shortlist_name="my-targets", site={site_ref, lat, lng, capacity_mw}) — objectives are optional. If you DID rank the site (analyze_site / rank_sites), pass those metric fields inside site and your objectives map too, and the re-scoring reuses them. Requires an API key so the list is private to you and survives to your next conversation: call claim_free_key first if you have none.

Input Schema

NameRequiredDescriptionDefault
siteYesSite object. MINIMAL form is enough: {site_ref, lat, lng, capacity_mw}. Richer is better — add any analyze_site metric fields (risk_resilience, fiber_connectivity, water score…) and those become what gets re-scored later.
notesNoOptional free-text note, e.g. "strong fiber, acceptable water"
objectivesNoOPTIONAL {field: signedWeight} map (+maximize/-minimize) if this site was ranked under explicit objectives — stored so re-scoring reuses the same criteria. Omit it and DC Hub weights the site's own metric fields equally.
shortlist_nameYesName of the shortlist, e.g. "Q3-2026-1GW-targets" — created if new. REQUIRED.

  7. Addedv2.3.8

TDQS

A4.8/5.0
Behavior5/5

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

Annotations only cover the write/idempotency/safety profile. The description adds substantially more: what is persisted (objectives map + current percentile objective_score), the re-scoring/drift semantics, that the list survives across conversations, and that it is scoped to the caller's API key, which implies an auth requirement. That is real behavioral context beyond the structured fields.

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 and dense, with the persistence rationale stated first and the call mechanics after. Slightly heavy: the minimal-site guidance appears in both the description and the site property schema, and the em-dash parentheticals ('Phase 5 statefulness') add noise an agent does not need to invoke the tool.

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?

A mutation tool with an output schema, so return values need not be described. Prerequisite (API key), scoping, persistence horizon, what gets stored, and the follow-up tool are all present; nothing an agent needs to call this correctly is missing.

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, and the schema itself already explains objectives semantics and the site object. The description earns above baseline by giving a concrete minimal call signature with literal argument values and by clarifying the ranked-vs-unranked fork that determines whether objectives/metrics matter at call time.

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 ('keep a data center site on a named shortlist that survives across conversations') and immediately distinguishes the artifact from siblings: it is durable, API-key-scoped state paired with get_shortlist, not a one-off save_site. An agent can tell it apart from save_site, list_saved_sites, and get_shortlist without opening a 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 ('build a durable siting shortlist across days/weeks'), explicit minimal invocation with concrete argument values, explicit conditional guidance ('if you DID rank the site... pass those metric fields'), and an explicit prerequisite with the alternative named ('call claim_free_key first if you have none'). It also names get_shortlist as the downstream partner.

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