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

With no annotations provided, the description carries full burden but provides minimal behavioral context. It states the tool sends emails but doesn't mention delivery guarantees, rate limits, authentication requirements, error conditions, or what happens with invalid addresses. For a mutation tool with zero annotation coverage, this is inadequate.

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 extremely concise at just 8 words, front-loading the core purpose immediately. Every word earns its place with no redundancy or unnecessary elaboration.

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 an email-sending tool with 5 parameters, 0% schema coverage, no annotations, but with an output schema, the description is insufficient. While the output schema may document return values, the description doesn't address critical aspects like delivery behavior, error handling, or parameter usage. Given the mutation nature and complexity, more context is needed.

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 all 5 parameters are undocumented in the schema. The description only mentions 'optional plain-text fallback' which corresponds to one parameter (plain_fallback), leaving the other 4 parameters (to, subject, html_body, cc) completely unexplained. The description fails to compensate for the schema's lack of 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 ('Send an HTML email') and resource ('email'), making the purpose immediately understandable. It distinguishes from sibling 'send_email' by specifying HTML format with plain-text fallback, though it doesn't explicitly contrast with 'send_email_preview'.

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 provided about when to use this tool versus alternatives like 'send_email' or 'send_email_preview'. The description mentions optional plain-text fallback but doesn't explain when this feature should be used or what distinguishes this tool from its siblings.

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