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

Annotations already establish readOnlyHint=true, and the description adds useful behavioral detail by enumerating the return fields (title, author, read time, publication date, tags, direct link). This is valuable given no output schema. It doesn't mention pagination or rate limits, but these are not critical for a read-only search.

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 two concise sentences, front-loaded with the core action and output summary, followed by relevant use cases. No wasted words or redundant information.

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 search tool with full schema coverage and annotations, the description covers the essential aspects: purpose, return format, and use cases. It could mention pagination or result limits, but the schema default for max_results mitigates that. Overall, it's complete enough for an agent to use effectively.

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 coverage is 100% with detailed descriptions for both query and max_results, so the description doesn't need to compensate. The description itself adds no additional parameter insight, such as how max_results affects output, but the baseline of 3 is appropriate given the high schema coverage.

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 'Search' and the resource 'dev.to platform', specifying it targets developer articles, tutorials, and technical posts. This effectively differentiates it from sibling tools like search_podcasts and search_events.

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 a direct 'Use for' clause listing appropriate scenarios: learning dev topics, finding tutorials, and staying updated on community trends. It doesn't explicitly mention when not to use, but the platform-specific scope gives implicit guidance relative to siblings.

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