Create asset

create_asset

Create a new asset. Requires assets:write scope. IMPORTANT - Location hierarchy: always resolve top-down by calling list_sites first, then list_buildings filtered by site_id, then list_locations filtered by building_id. Provide all three IDs (site_id, building_id, location_id) explicitly. System hierarchy: similarly resolve via list_system_classes → list_system_groups → list_systems.

Input Schema

NameRequiredDescriptionDefault
nameYesAsset name (required)
modelNoModel name/number
site_idNoSite ID - resolve first via list_sites
asset_idNoCustom asset identifier (unique per tenant)
quantityNoQuantity
image_urlNoImage URL
status_idNoStatus ID from list_asset_statuses. The status with system_key archived archives the asset; any other status restores it.
system_idNoSystem ID - resolve last via list_systems filtered by system_group_id

salvage_value_percentageNoSalvage value percentage (0-100)
likelihood_of_failure_scoreNoLikelihood of failure score, 1-5. Derived from condition_score unless set: setting it makes it a manual value that condition changes no longer replace; send null to return it to derivation.
consequence_of_failure_scoreNoConsequence of failure score, 1-5. Setting it makes it a manual value that a system change no longer replaces; send null to return it to the default from its system.

  6. First observed

TDQS

B3.4/5.0
Behavior3/5

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

Annotations already declare the mutation profile (readOnlyHint=false, destructiveHint=false, idempotentHint=false). The description usefully adds the required auth scope, but says nothing about return behavior, duplicate handling, or what creation leaves in an unset state.

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-loads the core action, then scope, then the two resolution chains in order. It is compact for a 39-parameter tool with no wasted prose, though the 'IMPORTANT' label and repeated ID enumeration are slightly heavy.

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

Completeness3/5

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

No output schema exists, so return values need not be described, and the description covers auth and the key resolution workflow. Still, for a tool this complex it omits sibling disambiguation (infrastructure asset vs. bulk create) and any note on uniqueness or duplicate behavior.

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

Parameters3/5

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

Schema description coverage is 100%, so the schema already documents all 39 parameters, including the hierarchy hints ('resolve first via list_sites'). The description restates that ordering, adding some workflow value but little beyond the schema's own per-field guidance.

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 clear verb+resource ('Create a new asset'), so the action is unambiguous. However, it does not differentiate from close siblings like create_infrastructure_asset or bulk_create, which an agent may need to choose between.

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

Usage Guidelines3/5

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

Gives a prerequisite ('Requires assets:write scope') and prescribes the top-down hierarchy resolution workflow. It never states when to prefer this over bulk_create or create_infrastructure_asset, so alternative 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.
