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

Annotations already declare readOnlyHint=true, openWorldHint=false and destructiveHint=false, so the safety profile is covered. The description still adds substantial behavioral context beyond that: it is free, paginated at 20 per page with a 50 max, exposes next_offset for paging, describes the exact return fields plus a free 25-row sample link, and documents the special category='list' mode.

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?

It is dense and front-loaded: catalog scope first, then filtering, then return shape and paging. It reads as one long compound sentence with some crammed clauses (category list mode tacked onto the end), which slightly hurts scannability, but there is no filler.

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?

With no output schema, the description carries the return-shape burden and does so — slug, name, one line, category, row count, tiers, page and sample links — plus paging behavior. For a zero-required-parameter browse tool, nothing an agent needs to call it correctly is missing.

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%, so the baseline is 3, but the description adds real meaning the schema does not: query matches words against name, one-line summary, audience and description (the schema only gives examples), and category='list' is a special mode. It also restates the 20/50 paging limits, which is minor duplication.

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 states a specific verb and resource ('Browse the Tensorust dataset catalog') and immediately scopes it: 145 entity-level datasets, one row per organization/site/loan/filing. That clearly distinguishes it from siblings like get_dataset (single dataset retrieval) and get_dataset_sample (sample rows), so an agent can pick it without opening schemas.

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?

It gives an explicit usage path: filter by query and category, or pass category='list' to enumerate categories with counts. What's missing is an explicit hand-off to alternatives — it implies that the returned slug feeds get_dataset / get_dataset_sample but never names those siblings or says when to stop browsing and drill in.

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