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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds that the full definition, attributes and metadata come back, which is useful given there is no output schema, but it doesn't address the include_content toggle (default true) or error behavior for bad UUIDs.

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 key identifier front-loaded. The second sentence largely restates "full details" as "complete schema definition including all attributes and metadata," so there is a little redundancy but no bloat.

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 simple two-parameter read tool with full schema coverage and annotations, the description covers the essential return shape in the absence of an output schema. Missing only edge-case behavior such as not-found handling or the effect of include_content=false.

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 100%, so both schema_uuid and include_content are already documented in the schema. The description adds no meaning beyond that and actually implies a always-complete response, which sits slightly at odds with the include_content option.

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 and resource ("Get full details of a specific schema") and the lookup key (UUID), which is enough for an agent to distinguish it from list-style siblings like schema_list. It never names a sibling outright, so differentiation is inferred rather than stated.

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?

Usage is only implied: fetch by UUID when you already have one. There is no explicit when-to-use versus alternatives (schema_list, schema_list_project), and no note about what to do if the UUID is unknown.

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