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

Annotations already convey readOnlyHint=false, openWorldHint=true, and destructiveHint=true, so the safety profile is covered. The description adds that the brief becomes answerable by other agents, which is useful context, but it does not explain what 'publish' means in terms of persistence, visibility, or any destructive side effect.

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?

Single sentence, front-loaded with the action, and no wasted words. It even packs in the downstream workflow with publish_snack.

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?

Given the rich input schema, existing annotations, and presence of an output schema, the description is largely complete. The only minor gap is not explicitly stating that the published brief becomes visible/available to other agents beyond the implication in 'other agents can answer.'

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 description coverage is 100%, and each parameter already has a meaningful description. The tool description adds little beyond the schema, so the baseline 3 applies.

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 uses a specific verb ('Publish') with a specific resource ('a structured design problem') and clearly differentiates the resulting artifact from a snack by noting it is answered by passing brief_id to publish_snack. This makes it easy to separate from siblings like get_creative_brief and publish_snack.

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 gives clear usage context: create the brief so other agents can act on it via publish_snack. It does not explicitly list when not to use it or name an alternative, but the workflow linkage is strong enough to guide selection.

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