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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds valuable context about the response contents (source links and credits) and the 'public catalog' scope, which goes beyond the annotations. No contradiction is present.

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 two concise sentences with no filler. The action is front-loaded, and the return-value note is brief but informative. Every sentence earns its place.

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?

With no output schema, the description gives a high-level idea of the response ('source links and credits') which is sufficient for an agent to know what to expect. It does not cover error cases or availability, but for a simple read tool with strong annotations, this is adequate.

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%: the schema already documents that 'id' must be a canonical UUID (case-insensitive) and explains why slugs are not valid. The description simply repeats 'by UUID' without adding further parameter meaning, so a baseline score of 3 is appropriate.

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 ('Read') and resource ('published ingredient by UUID') and notes the return content ('public catalog data with source links and credits'). This clearly distinguishes it from sibling tools like search_ingredients (which search by criteria) and get_flour/get_pizza (different resource types).

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 implies usage when a UUID is available, but does not explicitly state when to prefer this over search_ingredients or get_flour. There is no mention of alternatives or exclusions, leaving the agent to infer the appropriate context from the parameter requirements.

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