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

Annotations already cover read-only, open-world, and non-destructive behavior, while the description adds useful context: it returns pagination, source documentation, and access requirements, and it clarifies that marketplace stars are not plugin-level ratings. It also explicitly states the tool does not run tools or certify safety, which meaningfully sets expectations beyond the 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 front-loaded and compact: it states the search scope, return contents, a caveat about stars, and a safety/scope disclaimer in four efficient sentences. Every sentence carries useful information without repetition.

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?

The description adequately covers purpose, return shape, and safety caveats, and the annotations handle the safety profile. However, with no output schema and no schema parameter descriptions, the missing parameter guidance and lack of sibling routing leave clear gaps for a four-parameter search tool.

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 explain the four parameters, but it never mentions type, query, limit, or offset, nor the enum values. The phrase 'Returns pagination' hints at paging but does not explain the paging parameters or search behavior.

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 names a specific verb and resource: searching pinned repository and official marketplace metadata. It is clear enough to distinguish this from a tool that runs or installs something, but it does not explicitly contrast itself with siblings such as search_listings or search_skills.

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 explains what the tool searches but gives no explicit when-to-use guidance or alternative routing. It says the tool does not run or certify tools, but that is a scope disclaimer rather than usage guidance against the available sibling tools.

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