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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds useful context about authorization ('governed by the caller's existing scopes, role and approval preferences') and freshness ('Loads a fresh ... asset'), but never explains what the 'optional actions' are or whether they write anything.

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

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

Three compact sentences, front-loaded with the trigger condition. Phrasing like 'approved document references' and 'approval preferences' is a little abstract but nothing is wasted.

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

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

For a single-parameter read tool with rich annotations and no output schema, the description covers the when and the authorization model, but leaves the required assetId undocumented and the 'optional actions' undefined. An agent could call it, but with avoidable guesswork about the identifier.

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

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

There is one parameter (assetId) with 0% schema description coverage, so the description carries the full burden — and it never mentions assetId, its format, its length limit, or how to obtain a valid value (e.g. via search_assets). This is a real gap for a required identifier.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

It states a verb and resource ('inspect one known asset', 'Loads a fresh, authorized asset and approved document references'), but the addition of 'initiate an authorized work order or maintenance plan' muddies what the tool actually does. Siblings like get_asset_details and view_assets are never mentioned, so an agent cannot tell why it should pick this over those.

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

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

'Use this when the user wants to inspect one known asset' gives a usable trigger condition, implying the asset is already identified. But there is no guidance on when NOT to use it versus get_asset_details, view_assets, get_asset_service_history, or the draft_* tools for creating work orders.

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