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

With no annotations, the description carries the full disclosure burden and offers none of it. It says the deliverable 'ships as a full prompt kit with step-by-step instructions' but never states what the tool actually returns, whether the optional query scopes the analysis or the generated workflow, or whether any state is created.

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?

Three sentences of marketing copy, with the least relevant claim ('restaurant & brand intelligence pack') front-loaded where scope should be. The support-promise sentence consumes space without helping an agent decide or call correctly.

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?

No annotations and no output schema, so the description must explain the return shape and behavior — it does neither. For a tool whose name implies domain analysis but whose text implies template generation, the missing clarification of the actual contract is a major 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?

There is a single optional parameter with 100% schema description coverage, so the schema already defines 'query' as an optional scoping string. The description adds no meaning beyond it and leaves ambiguous whether the query scopes the skincare analysis or the workflow-generation step.

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 name promises a skincare ingredient decoder, but the description opens by branding itself as a 'restaurant & brand intelligence pack' and then reframes the tool as something that 'generate[s] a ready-to-use skincare ingredient decoder workflow.' It is never clear whether the tool decodes ingredients or merely emits a prompt kit that does, and the restaurant framing actively misleads against the name and against skincare siblings.

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?

No when-to-use guidance, no conditions, no exclusions. Siblings such as skincare-troubleshoot and checkup-report-decoder exist, but nothing tells the agent how to choose between them, and the '30-day support promise' is irrelevant to invocation decisions.

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