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

The readOnlyHint and openWorldHint annotations already establish that this is a safe, closed-world read operation. The description adds useful content scope by saying it returns plan directories, historical outcomes, and the next submission, but it omits ordering, pagination, and response-shape details.

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 definition is one compact sentence with no filler and is front-loaded with scope. It is slightly cryptic as a fragment, but every phrase contributes to explaining what the tool returns.

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 simple read-only tool with a fully documented optional parameter and annotations, the description gives an adequate high-level account of returned content. However, without an output schema, phrases like 'what happened there' remain vague, and the relationship to sibling tools is not clarified.

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 single product parameter is fully documented in the schema, including the default behavior when left empty. The description does not add further parameter meaning, so the baseline of 3 applies for high schema description coverage.

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 states a specific scope: every directory on this product's plan, what happened there, and the next one to submit. This is more specific than the tool name alone, but it does not explicitly distinguish itself from close siblings like plan_submissions or record_submission.

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 a use case by mentioning history and the next submission, but it gives no explicit when-to-use guidance or alternatives. An agent must infer whether to call this versus plan_submissions or record_submission.

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