exact_get_entity_schema

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds mild behavioral context via 'discovered support' and 'allowed entity,' but it does not explain what 'discovered support' means, how discovery happens, or what the response contains.

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?

The description is a single, efficient sentence that front-loads the core action and output categories. There is no filler or redundancy, and every word contributes meaning.

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 read-only, idempotent introspection tool with one parameter, the description is adequate but not complete. It names the output categories but does not define 'discovered support' or clarify how the entity parameter should be specified, leaving some ambiguity despite helpful sibling names like exact_list_entities.

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 the description must compensate for the single required 'entity' parameter. It only adds the phrase 'allowed entity,' which gives a minimal constraint but does not explain what values are valid, how they are formatted, or where the allowed list can be obtained.

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 clearly states the verb 'Return' and the resource ('keys, properties, types, and discovered support for an allowed entity'). It is distinguishable from siblings like exact_get_entity, which would return actual entity data rather than its schema, though it does not explicitly name that 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?

No guidance is given about when to use this tool versus alternatives such as exact_list_entities or exact_get_action_schema. There are no explicit conditions, prerequisites, or exclusions, so the agent must infer usage from the tool name and sibling context.

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