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

Annotations already carry readOnly, idempotent, and non-destructive hints, so the safety profile is covered. The description usefully adds the data-exposure boundary (no secrets, contacts, or original files), but says nothing about result shape, pagination behavior, or what 'authorised' scoping means in practice.

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 the scope constraint front-loaded and no wasted clauses beyond the redundant 'through the existing application'.

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?

A 4-parameter, paginated read tool with no output schema and 0% parameter documentation needs the description to explain identifier semantics and result content; it does neither. Only the data-exposure boundary is covered.

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%, so all four parameters (targetId, query, limit, offset) rest on the description, which mentions none of them. An agent cannot tell whether targetId is the upload job ID or a tenant/location scope, nor how query filtering works.

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 verb+resource ('read bulk upload status') but leaves the resource ambiguous — it's unclear whether this returns a single job's status or a status summary, and the sibling list_bulk_uploads is not differentiated. The clause 'through the existing application' adds no distinguishing meaning.

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 indication of when to use this versus list_bulk_uploads, get_agent_import_jobs, or the other status tools. The only constraint ('metadata/approved fields only') is a data-scope rule, not usage guidance.

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