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

With no annotations provided, the description carries the transparency burden. It discloses the data source (SEC EDGAR), that every row links to its filing, and the licensing terms (Free, CC BY 4.0), which is useful context. It does not mention return structure, pagination behavior beyond the schema, or any read-only guarantees.

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 very compact and front-loaded with the core topic, followed by source, row-link behavior, and licensing. The fragmentary style is slightly terse, but every clause contributes information.

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 single-parameter tool with no output schema, the description is mostly adequate, covering topic, source, and row-link behavior. However, it never states what fields or data each row contains beyond the filing link, which would help an agent understand the result without invoking the tool.

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%, so the schema already fully documents the single `limit` parameter. The description adds no additional semantics about the parameter, but none are necessary given full 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 identifies a specific resource: SEC 8-K Item 2.05 restructuring events, with a clear data topic around exit/disposal costs. Although it lacks a verb like 'retrieves,' the regulatory reference distinguishes it from all sibling data tools.

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 implied through the topic: an agent needing restructuring-related SEC 8-K Item 2.05 data should use this tool. However, there is no explicit when-to-use guidance, no mention of alternatives, and no exclusion criteria.

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