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

With no annotations, the description carries the load and does reasonable work: it discloses the data source (SEC EDGAR), the freshness window (this week), that every row links to its filing, and the reply shape (one-line answer plus date). It omits auth needs and rate limits, but the behavioral picture is materially fuller than a bare restatement.

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?

Compact and front-loaded, leading with the user question the tool answers. Slight waste in the fragment 'Annual Meetings.' which restates the topic already conveyed, but overall efficient.

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-optional-parameter lookup with no output schema, the description supplies the essentials: what it returns, where data comes from, licensing, and the response format. Enough for an agent to call correctly, though it says nothing about limit behavior, which is left entirely to the schema.

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?

Only one parameter exists and schema description coverage is 100%, so the schema already documents limit fully (default 50, ceiling 200, truncation behavior). The description never mentions limit, so it adds nothing beyond the schema; baseline 3 is appropriate.

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?

Opens with a specific interrogative framing a concrete verb and resource: public companies filing annual meeting proxies this week, pinned to SEC Form DEF 14A. The DEF 14A / annual meeting topic cleanly distinguishes it from siblings like get_agreements, get_mergers, or get_charter_amendments.

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 topic and data source imply when the tool is relevant (annual meeting proxy filings this week), but there is no explicit when-to-use or when-not-to-use statement and no named alternative among the many sibling tools. Usage is inferable from subject matter rather than stated.

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