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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so safety is covered. The description adds useful scope detail (only fields the team added, and only status/checkbox/text types), but says nothing about behavior for collections with no custom fields, permission requirements, or result ordering.

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?

A single well-formed sentence with no filler, and the resource being read is front-loaded after the verb. It is perhaps too terse given the lack of other guidance, but nothing in it 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 one-parameter read tool with annotations covering safety, the description is adequate for selection but incomplete for invocation: with no output schema, it never indicates what a returned field looks like (id, name, type), which the agent would need to act on the results.

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% and the single parameter (collection_id) is never mentioned in the description. The phrase 'a collection' weakly implies the parameter scopes to one collection, but there is no added meaning about format, requiredness, or how to obtain the id.

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?

The description states a concrete verb ('Reads') and a specific resource ('the status, checkbox and text fields a team added to a collection'), which is far more informative than the bare name. It implicitly distinguishes itself from list_collections/get_collection by scoping to custom field definitions, though it never names a sibling.

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?

There is no explicit when-to-use guidance, no exclusion of alternatives, and no prerequisites. The agent must infer that this is the counterpart to save_your_fields/set_your_field and that it should be called on a collection whose custom fields it wants to inspect.

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