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

With no annotations, the description carries the full behavioral burden. It does disclose scope limits (factual public records, links on bommel.bot only) and a boundary on how output may be used ('not advice, not a recommendation, not an invitation to act'), but it says nothing about auth requirements, read-only nature, or pagination/return shape.

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?

Four short fragments, front-loaded with 'Call this first' before the payload list. Nothing is padded, though the disclaimer clause is a third of the total length and could be tighter.

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 zero-parameter read of public site metadata with no output schema, the description covers what is returned and the scope of that content, which is enough for correct invocation. Missing details about response shape and read-only behavior are minor at this complexity.

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 tool takes zero parameters, so there are no parameter semantics to document. Baseline 4 applies; the description does not need to compensate for anything here.

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?

It enumerates the concrete payload (publisher, purpose, MCP URLs, product pages) and scopes it to bommel.bot, so an agent can tell it apart from list_directory or search_feed. It never states a verb ('returns' is implied rather than written), so it is clear but not fully formed as a purpose statement.

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?

'Call this first' is explicit ordering guidance and implies an entry-point role before the other tools. It names no exclusions or alternatives, and gives no condition under which it should be skipped, so it stops short of full when/when-not routing.

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