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

No annotations are supplied, so the description carries the full burden; it does disclose what kinds of records appear in the result (emails, client-system changes, spend), which is genuine behavioral content. However, it says nothing about read-only safety, ordering, volume, or whether already-decided items are excluded.

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?

A single front-loaded sentence with the resource stated first and a compact parenthetical that earns its space by naming the item categories. No filler or redundant restatement of the title.

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 no-param read tool with no output schema and no annotations, the description should at least sketch the shape of returned items; it gives only category labels. It is adequate to decide when to call, but not to know what fields to expect back.

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 tool takes zero parameters, which is the baseline-4 case; there is no parameter meaning left for the description to add. Nothing in the schema is left ambiguous.

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 names a specific resource — "Actions waiting for the owner's approval" — and enumerates the content types (emails, changes in client systems, spend), so an agent knows exactly what comes back. It stops short of differentiating itself from adjacent siblings such as decide_approval or what_needs_me, which is why it isn't a 5.

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?

There is no explicit when-to-use statement and no named alternative. An agent must infer from the name alone that this is the read side of the approval workflow and that decide_approval is the action counterpart.

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