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

Annotations already declare readOnlyHint and idempotentHint, so the bar for additional context is lower. The description adds that it returns category-bucketed example questions with exact tool + argument shape, and that it draws from a live catalog, which gives the agent insight into the output format and dynamic nature. However, it does not discuss any potential side effects or rate limits, but these are not expected for a read-only suggestion tool.

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 quite long, listing many example trigger phrases and repeating the same idea in multiple ways. While it contains useful guidance, it is not as concise as it could be; the core purpose statement appears after a list of example queries. It earns a 3 for being informative but not tightly edited.

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 tool is simple (one optional parameter, no output schema). The description fully covers what it does, when to use it, how to use the parameter, and what the response looks like. There are no gaps that would leave an agent confused.

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 fully describes the optional `topic` parameter with allowed values. The description adds value by explaining the effect of omitting vs providing `topic` (full spread vs focused) and gives specific examples like 'finance', 'pharma', 'betting'. This enriches the schema's static list with usage semantics.

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 identifies the tool as an onboarding entry point that suggests example questions about what Pipeworx can do, with specific verb 'returns category-bucketed example questions'. It distinguishes itself from siblings by naming itself the FIRST tool to use when unaware of Pipeworx capabilities, and mentions meta-tools like ask_pipeworx, entity_profile, compare_entities.

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?

Explicitly states 'Use this FIRST when you do not yet know what Pipeworx can do for you, or to learn how to call the meta-tools...' providing clear when-to-use guidance. It also gives call variations (no args vs topic) and mentions that it draws from the live catalog, implying it's for initial exploration rather than specific queries.

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