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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), so the bar is lower. The description still adds real context: accepted query languages, the provenance of `rating` (App Store/SourceForge with review count), the meaning of maintainer_tool, and the semantics of an empty result set.

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 core purpose is front-loaded in the opening clause, and the parenthetical enumerations are dense but each item earns its place by telling the agent what content is indexed. The long material-tool list is the only mildly expensive section.

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?

There is no output schema, so the description must carry return-value context, and it partially does by explaining the rating and maintainer_tool fields and the empty-result case. It stops short of describing the full result shape (title/link/category fields), which an agent would otherwise have to discover by calling.

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 all five parameters are already documented, which sets the baseline at 3. The description adds only marginal parameter-level meaning — bilingual query acceptance and the source of the rating used by min_rating — but nothing about limit, category, or interaction between filters.

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 ('Find') and resource ('free home renovation tools for a task') and then enumerates the concrete content classes returned (calculators, templates, planners, directories, apps, forums). This makes it trivially distinguishable from get_tool (fetch one) and list_categories (enumerate taxonomy).

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?

Usage is implied by the query-oriented framing ('Find ... for a task'), and the note that an empty result means nothing in the list fits usefully sets expectations. However, it never states when to prefer this over get_tool or list_categories, nor any prerequisite steps, so routing guidance is left to inference.

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