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

Annotations already indicate the tool is read-only, idempotent, and non-destructive. The description does not add further behavioral details like response structure, pagination, latency, or authorization needs. However, it correctly implies a safe query operation, consistent with 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?

The description is a single sentence of 9 words, immediately stating the core functionality. It avoids superfluous details, but could be slightly expanded to improve clarity without losing conciseness.

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?

Given the tool has only two optional parameters with 100% schema coverage and an existing output schema, the description is largely sufficient for understanding the tool's purpose and usage. However, it does not mention default behavior (e.g., default lookback days) or the format of results, though these are covered 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 100%, so the schema adequately documents both 'days' and 'severity' parameters. The description only paraphrases the schema by mentioning 'severity and time range', adding no new semantic information about expected values, defaults, or constraints.

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 tool retrieves competitive alerts with filtering by severity and time range. This distinguishes it from sibling tools like get_blog_updates or get_patent_filings, which target different content types. The verb 'Get' and resource 'competitive alerts' are specific and unambiguous.

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 provides no guidance on when to use this tool versus alternatives such as get_trending_topics or get_newsletter_content. It does not mention prerequisites, exclusions, or context for choosing this tool. An explicit usage note would improve agent decision-making.

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