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

No annotations are provided, so the description carries the full burden. It discloses the retrieval behavior (topic narrows to matching entries, omission returns the whole guide), but says nothing about the return shape or size of the guide entries, which for a documentation tool is the main behavioral question left open.

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?

Two sentences, front-loaded with what the tool is and the URL, followed by the parameter behavior. The topic enumeration is dense but every item helps an agent decide whether a user's question is covered.

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 single-optional-parameter, no-output-schema, unannotated help tool, the description covers identity, coverage scope, and invocation semantics. Only the return format remains unstated, and the absence of a return contract is the one remaining gap.

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% and already supplies example values, but the description goes beyond it by explaining the matching semantics ('the words a question uses as topic') and the omit-for-everything default — meaning the schema alone would not convey.

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 resource (the Reseller Terminal's help text) with its URL and enumerates exactly what topics it covers — counters, card numbers, search/sort, filters, saved views, statuses. It is conceptually distinguishable from get_started_guide, though it never explicitly contrasts itself with that sibling.

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 clearly states how to invoke: pass the question's words as 'topic' to get matching entries, or omit it for the whole guide. What is missing is an explicit when-to-use-vs-alternatives rule, e.g. when to reach for resell_guide instead of get_started_guide or find_page.

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