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

With no annotations provided, the description carries full burden but offers minimal behavioral insight. It mentions creation and merging but doesn't disclose critical details like required permissions, whether operations are atomic/reversible, error handling, or how merging works with parameters like 'replace_attributes'. The description doesn't contradict annotations (none exist), but fails to compensate for their absence.

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 functionality. Every word earns its place with no redundancy or fluff, making it easy to parse quickly.

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 complex mutation tool with 9 parameters, 0% schema coverage, no annotations, and multiple sibling alternatives, the description is insufficient. While an output schema exists (reducing need to describe returns), the description lacks guidance on usage, parameter meanings, and behavioral traits needed for safe and effective invocation.

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 but adds no parameter-specific information. It doesn't explain what 'entity_id', 'entity_type', or other parameters mean, how 'replace_attributes' affects merging, or the purpose of nullable fields. With 9 parameters completely undocumented in both schema and description, this is inadequate.

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 ('create' or 'merge updates') and resource ('entity'), making the purpose understandable. However, it doesn't differentiate from sibling tools like 'create_entity', 'update_entity', or 'get_or_create_entity', which would require explicit comparison to achieve a perfect score.

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 usage based on entity existence ('if missing' vs 'existing'), but provides no explicit guidance on when to choose this tool over alternatives like 'create_entity', 'update_entity', or 'get_or_create_entity'. No prerequisites, exclusions, or comparative context are mentioned.

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