get_homepage_context

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

With no annotations provided, the description carries the full burden. It only says 'return', implying a read-only action, but does not clarify what 'related brand/store resources' entails, whether the operation is expensive, or what error cases might arise. This is minimal transparency beyond the verb itself.

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 a single clear sentence with no wasted words. It is appropriately sized for a simple getter tool, though 'related brand/store resources' could be more specific.

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 no-param, no-output-schema tool, the description offers a high-level idea of the return content but leaves 'related brand/store resources' vague. Given the large sibling set, the agent may need more detail to confidently choose this tool over similar context retrieval tools like get_landing_page_context.

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 has zero parameters, so there are no parameter semantics to explain. Per guidelines, a baseline of 4 is appropriate. The description's mention of 'source and related resources' refers to output context, not input parameters.

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?

Description clearly states the tool returns homepage source and related brand/store resources, using a specific verb and resource. It distinguishes itself from siblings like get_landing_page_context by focusing on 'homepage', but does not explicitly differentiate itself within the larger context of similar resource retrieval tools.

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 provides no guidance on when to use this tool versus alternatives. It does not mention any conditions, prerequisites, or exclusionary cases, leaving the agent to infer usage from the tool name alone.

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