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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds real value by disclosing what is deliberately withheld from the response (private storage references, upload capabilities), which is information the annotations do not convey.

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?

Two short sentences with zero filler, and the operation and its most surprising constraint (what is never returned) are front-loaded.

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?

An output schema exists, so return-shape explanation is unnecessary, and annotations cover safety. The description is nearly complete for a one-parameter read; only error/not-found behavior or ownership failure handling is unstated.

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?

Schema description coverage is 0%, but the single parameter's UUID regex pattern fully constrains the accepted format, so an agent knows what to supply. The description adds nothing about the id's semantics (e.g. asset id vs. a nested reference), leaving a minor gap.

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?

States a specific verb plus resource ('Read safe owned asset metadata'), which is clearly distinct from the sibling list tool assets_list. It doesn't explicitly name the sibling to differentiate, but the singular 'asset' framed as an ownership-scoped read makes the intent unambiguous.

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?

No guidance on when to call this versus assets_list or uploads_get, and no note on what happens if the caller doesn't own the asset. Usage must be inferred from the word 'owned' alone.

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