Update infrastructure asset

update_infrastructure_asset

DestructiveIdempotent

Update an existing infrastructure asset (feature) by ID. To change geometry, provide a new GeoJSON Point/LineString matching the existing feature_type. Computed columns (length_m, slope_pct, risk_score) cannot be set. Requires infrastructure_assets:write scope.

A3.5/5.0

Behavior4/5

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

Annotations already signal destructiveHint=true, idempotentHint=true and readOnlyHint=false. The description adds genuinely non-obvious behavior: the immutability of computed columns, the geometry-type constraint, and the required infrastructure_assets:write scope. It doesn't disclose whether omitted fields are cleared or preserved (partial vs full replace), which is the main remaining behavioral unknown for a destructive update.

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?

Three tight sentences, front-loaded with the operation and ID requirement, then constraints and auth. Every sentence adds information; no filler or restatement of the title.

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

Completeness2/5

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

For a 55-property destructive mutation with no output schema, the description leaves major gaps: it doesn't say whether the update is partial or full-replace, doesn't describe any of the enum-bearing fields, and gives no sense of which of the many attributes are meaningful together. The geometry and scope notes are good but far from sufficient for a schema this large.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 55 parameters and only 5% schema description coverage, the schema documents almost nothing, so the description carries the burden. It explains only one parameter (geometry, including the Point/LineString constraint) and names three non-settable computed columns; the remaining ~50 fields (name, lanes, model, dates, impact scores, enum fields, etc.) have no semantic help in either place.

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 specific verb+resource ('Update an existing infrastructure asset (feature) by ID'), which is distinguishable from the create/delete/get/list siblings of the same entity. It does not explicitly contrast with near-neighbours like bulk_update or update_asset, but the entity and operation are unambiguous.

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?

Gives concrete when-to-use detail: how to change geometry (provide a GeoJSON matching the existing feature_type) and an explicit when-not ('computed columns length_m, slope_pct, risk_score cannot be set'). It never names bulk_update or an alternative tool for multi-record edits, so it stops short of full routing guidance.

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