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

Annotations already declare read-only, idempotent, open-world, and non-destructive behavior, so the description need not restate safety. It adds useful context beyond annotations: the reply opens with a one-line answer and date, data comes from SEC EDGAR, rows link to filings, and the data is free under CC BY 4.0.

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 front-loaded with the core question and remains compact. A couple of fragments, such as the standalone 'Restructuring.' line, add minor redundancy but do not obscure the main point.

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 one-parameter, read-only retrieval tool with no output schema, the description covers the data source, the shape of the opening reply, filing links, and licensing. It is nearly complete, though the exact time-window semantics of 'this week' could be stated more explicitly.

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 `limit` parameter is fully documented in the schema, including default 50, ceiling 200, and total/returned/truncated response metadata. The description adds no parameter-level meaning, so the baseline score of 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 states a specific question and resource: public companies reporting restructuring costs, tied to SEC 8-K Item 2.05 exit/disposal costs. It is clear and concrete, but it does not explicitly distinguish itself from any sibling tools, which are numerous.

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 by framing a weekly question about restructuring costs, but it gives no explicit when-to-use, when-not-to-use, or alternative-tool guidance. The implied context is adequate but leaves selection to inference.

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