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

With no annotations, the description carries the full burden of behavioral disclosure. It usefully states that the result is empty when the watcher is disabled and that the content is historical, but it never explains whether the drain parameter consumes or clears modifications, nor does it mention side effects, permissions, or state changes.

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?

Three short sentences with a front-loaded definition, a clarifying contrast, and a concrete example. Every sentence earns its place and there is no filler or repetition.

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 conceptual use case is well covered and an output schema exists, but the total absence of drain/project semantics and the lack of annotations leave an agent unable to safely choose argument values or anticipate side effects. This is a significant completeness gap for a two-parameter 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 0%, and the description does not mention the drain or project parameters at all. 'drain' especially could materially change behavior, and 'project' implies filtering, but an agent has no information about either from the description or schema.

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 the resource as modifications recorded by the workspace watcher and explains that it shows timestamped changes between observations. The concrete 14:02/14:07 example clarifies that this is a historical view rather than a point-in-time snapshot, which differentiates it from refresh-like 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?

The point-in-time refresh contrast gives clear context: use this tool when you need change history between observations, not a current snapshot. It does not explicitly name sibling tools or state 'use X instead', so it stops short of a 5.

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