ecamm_comment_overlay

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

Annotations already declare that this is a non-read-only, non-destructive, closed-world action. The description adds useful specificity by saying the overlay targets the latest viewer comment, but it does not disclose side effects such as whether showing replaces an existing overlay or what happens when there are no comments.

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 definition is a single front-loaded sentence with no wasted wording. Both supported states are covered efficiently.

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 simple one-parameter overlay toggle, the description, annotations, and enum schema cover the essential behavior. Only edge-case behavior, such as absence of comments or overlay replacement semantics, is omitted.

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?

There is only one required enum parameter and schema description coverage is 0%, but the description directly maps the show/hide values to displaying or hiding the latest comment. The meaning is clear, though edge cases such as no available comment are not covered.

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 action (show/hide) and a specific resource (the most recent viewer comment as an overlay). It is clear on its own, but it does not explicitly differentiate itself from siblings such as ecamm_set_overlay or ecamm_post_comment.

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 show/hide states imply when to use the tool, but there is no explicit when-to-use or when-not-to-use guidance, and no alternative sibling tool is named for comparison.

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