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

With no annotations, the description must carry behavioral disclosure. It usefully states that the tool saves only and does not post, and that approval is separate, but it does not cover permissions, whether the edit overwrites existing text, behavior when no updated content is supplied, or response details.

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 functional content is front-loaded and reasonably brief, but it repeats the title, includes an Args section, and adds boilerplate about a 200 response and application/json content type that does not help tool selection or invocation.

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 mutation tool with no annotations and no output schema, the description covers the main save-versus-post distinction and the handle. However, the parameter-name mismatch and missing permission/overwrite behavior leave notable gaps for correct invocation.

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%, so the description needs to clarify both parameters. It explains the handle as a cdft_ value from list_comment_drafts, but refers to the text parameter as 'comment_text' while the schema defines 'updated_content'; this mismatch creates confusion, and the nullable updated_content behavior is unexplained.

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 states a specific verb and resource: edit a comment draft by replacing its text with text the user wrote. It also distinguishes saving from posting and approving, giving an agent a clear sense of the operation, though it does not explicitly contrast edit_comment_draft with rewrite_comment_draft.

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?

It gives a clear usage condition: 'Use this when the user dictates their own wording,' and clarifies that approving is still a separate step. It does not explicitly name the alternative rewrite tool, but the when-to-use guidance is strong.

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