zernio_like_comment

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

With no annotations, the description bears full responsibility for behavioral disclosure. It only states the action without detailing side effects, permissions, reversibility, or rate limits. The phrase 'or react' is ambiguous regarding what reactions are possible.

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 description is very concise (one phrase) and front-loads the core purpose. However, it is so brief that it may omit useful context, but it avoids fluff.

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?

Given no output schema and no annotations, the description is incomplete. It does not specify return values, possible errors, or platform constraints. For a simple action like liking a comment, more context (e.g., effect if already liked) would be helpful.

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% (both parameters have descriptions). The tool description adds no extra meaning beyond the schema, so it meets the baseline of 3. It does not clarify the format or constraints of commentId or accountId.

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 'Like or react to a comment on a post,' which clearly identifies the action as liking/reacting to a comment. While it is specific about the verb and resource, it does not differentiate from sibling tools like zernio_hide_comment or zernio_reply_to_comment, but the name itself provides clarity.

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?

No usage guidelines are provided. The description does not indicate when to use this tool versus alternatives (e.g., zernio_react_to_message for messages), nor does it mention prerequisites or context for use.

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