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

Annotations already declare readOnlyHint=true and openWorldHint=true. The description adds valuable behavioral context beyond that: results are limited to the last 30 days, and each job includes a LaraBench detail page plus an original apply URL when available. This gives the agent a clearer picture of result freshness and content.

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 only three sentences long, with the purpose in the first sentence and additional constraints in the next two. Every sentence provides useful information: the resource and result fields, the 30-day time limit, and the links. No wasted words.

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 tool with 10 parameters and an output schema, the description covers the essential context: what is searched, the 30-day recency limit, and key result attributes. It omits details like pagination or default sorting, but these are likely covered by the output schema or are not critical for basic selection.

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?

The input schema has 100% coverage with each parameter described in its own 'description' field. The main tool description does not add any additional parameter semantics or clarify usage beyond what the schema already provides, so the baseline score of 3 applies.

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 a specific action ('Search'), the resource ('recent Laravel jobs indexed by LaraBench'), and the scope of results including description, salary, seniority, and employment type. This explicitly distinguishes it from the sibling tool 'search_laravel_news' by focusing on jobs rather than news.

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 makes it clear when to use this tool (to search Laravel jobs) and indirectly contrasts with the sibling tool for news. However, it does not explicitly state exclusions or mention the alternative by name, stopping short of full when/when-not guidance.

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