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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description aligns with these annotations and adds the 'authorized draft version' qualifier, but most of the behavioral safety information is redundant with the annotations.

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, front-loaded sentence with no filler. Every clause contributes either the action, the target scope, or the crucial side-effect guarantee.

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 3-parameter validation tool with an output schema and strong annotations, the description is largely sufficient. The main gap is parameter semantics, but required IDs are inferable from their names and the optional version is represented in the schema.

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 description only mentions 'draft version,' giving no explanation of required project_id and case_id or how version behaves when null. The parameter names are somewhat self-explanatory, but the description does not compensate for the missing schema-level parameter documentation.

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 action ('Validate'), the target resource ('one authorized incorporation draft version'), and the key non-effect ('without changing durable state'). This distinguishes it from mutation-oriented siblings like incorporation.update_draft and incorporation.submit_to_sparklaunch.

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?

The description implies that this tool is for read-only validation of a draft, but it never explicitly names sibling alternatives or states when to choose validation over get_case, update_draft, or submit_to_sparklaunch. 'Without changing durable state' provides helpful context, but the selection logic is left to inference.

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