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

No annotations are provided, so the description carries the full behavioral burden, and it delivers almost nothing. It does imply mutation/overwrite of an existing document (useful), but says nothing about whether the original content is lost, whether permissions are required, whether it is reversible, or how the new content is determined.

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?

It is a single short, front-loaded sentence with no padding, which is fine structurally. However, it reads as generic auto-generated boilerplate ('Run <product> action: <verb> <resource>') that spends its one sentence restating the tool name rather than conveying 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 mutating tool with no annotations and no output schema, the description omits everything an agent needs: how the rewrite is produced, what input content is expected, what happens to the existing document, and what a successful call returns. The gaps are significant relative to the tool's complexity.

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% for the single 'detail' parameter, so the schema already documents it; per the baseline rule a 3 is appropriate. The description adds no additional meaning about what 'detail' should contain for a rewrite operation.

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 verb ('rewrite') and a resource ('doc'), and the sibling list (create/delete/get/list_doc) makes the general category clear. But it does not say what a 'rewrite' actually does — full-content replacement, targeted edit, or LLM-driven rephrasing — so the agent cannot distinguish its precise effect from create_doc or a hypothetical update tool.

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 statement of when to use this tool versus alternatives such as docs__create_doc or docs__get_doc, nor any prerequisite (e.g., must the doc already exist, must an ID be supplied). Usage must be inferred entirely from the tool name.

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