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

No annotations exist, so the description carries full behavioral disclosure burden. It mentions ranking behavior (payment-verified first) and deduplication (collapsing near-duplicates), but does not clarify read-only nature, rate limits, or pagination maximums beyond schema descriptions.

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?

Three sentences with front-loaded key information (ranking criteria, deduplication). No wasted words, filters are listed concisely. Could be more structured with bullet points, but within token limits it is efficient.

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 browse/listing tool with no output schema, the description covers core behavior (ranking, deduplication, filters) but misses behavioral notes like pagination limits (schema covers max 50) and hints about when results may be empty. Could be more complete.

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?

Input schema has 100% description coverage, so baseline is 3. The description lists filter dimensions (category, capabilities, price, rating, availability, framework, free-text) and mentions the default sort by payment-verified completions, adding context beyond the schema's field names.

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 it is for browsing a public agent services directory. It specifies the ranking criteria (payment-verified completions first, then listing quality) and mentions collapsing near-duplicate listings, which helps distinguish it from sibling browse tools like 'agentlux_browse' and 'agentlux_resale_browse'.

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 lists available filters but does not provide guidance on when to use this specific browse tool over siblings like 'agentlux_browse' or 'agentlux_resale_browse'. It lacks explicit context on use cases or exclusions, though the filters imply a directory search scenario.

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