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

With no annotations, the description carries the burden of disclosing behavior. It states the report 'will appear in the merchant's Agent Reports dashboard,' establishing the audience and expected outcome. It does not mention permissions, reversibility, or response behavior, but the stated side effect is sufficient for a submission tool.

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 sentences, front-loaded with the primary action, and every clause adds value. There is no filler or repetition of schema content.

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?

The tool is simple, the schema covers all parameters thoroughly, and the description covers purpose, usage context, and the resulting dashboard behavior. There is no output schema and return values are not described, but for a send-report action this is not a critical omission.

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?

All six parameters have descriptions in the schema, so the description adds little beyond examples of report types. It does not elaborate on priority or action_items beyond the schema, so the baseline 3 is appropriate given 100% schema 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 uses a specific verb and resource: 'Send a report to the developer/owner.' It lists concrete use cases (SEO audits, growth ideas, data reports, etc.) and names the destination dashboard, clearly distinguishing it from sibling tools like list_my_reports, delete_report, and update_report_status.

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?

It provides explicit guidance on when to use the tool via 'Use this to submit...' and enumerates relevant report categories. However, it does not explicitly state when not to use it or name alternatives, so it does not quite reach a 5.

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