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

Annotations already declare readOnlyHint, idempotentHint and non-destructive behavior, so the safety profile is covered. The description still adds real context beyond them: the response carries rich recall content (hazard, stop-use instruction, remedies, contact, dates) and the write-side lifecycle is explicitly out of reach. Pagination, result counts and ordering are not mentioned.

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?

Front-loaded with the action and scope, then a field enumeration that earns its place because there is no output schema, then a short constraint sentence. The field list runs long in a single sentence but contains no filler.

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 single-parameter read tool with no output schema and full annotation coverage, the definition supplies enough: scope (connected account), returned content, and what cannot be done here. Only result volume/ordering behavior is left unstated, which is minor.

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 one optional parameter (language) with 100% schema description coverage, including the enum values and the fallback behavior for untranslated content. The description adds nothing about it, which is acceptable since the schema fully documents it, but that caps this at the baseline.

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 first clause gives a specific verb and resource ("Lists the recalls and safety warnings of the connected account") and then enumerates the content returned (kind, product, status, hazard, remedies, dates). An agent can tell what comes back without opening a schema. It stops short of naming how this differs from adjacent list tools such as list_deadlines or list_documents_due.

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?

Usage is only implied: the read-only listing nature plus the note that creating, publishing, notifying and closing happen in the dashboard. That negative scoping is useful, but there is no explicit trigger for when to call this versus other list tools, and no prerequisites stated.

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