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

Annotations already indicate idempotentHint=true and non-destructive nature. The description adds minimal context beyond the toggle behavior, but no contradictions. It does not explain side effects like whether hiding affects notifications or is reversible, but annotations cover core safety.

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?

Extremely concise: two sentences plus an arg list. Every element is necessary and front-loaded with the purpose. No wasted words.

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?

Despite no output schema, the tool is simple (2 required params, toggle operation). The description covers purpose and basic arg semantics adequately. However, it could mention the expected return (e.g., success status).

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 coverage is 50% (the 'hide' parameter has a description). The tool description restates the 'hide' parameter's meaning but adds no new semantics for 'reply_id', which lacks description in the schema. Thus, minimal additional value.

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 clearly states the verb 'Hides or unhides' and the resource 'a reply on a Threads post', making the tool's purpose unambiguous. It differentiates from sibling tools like meta_hide_comment or meta_hide_instagram_comment by specifying Threads context.

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 guidance is provided on when to use this tool versus alternatives such as hiding comments on Instagram or Facebook. The description does not mention prerequisites, limitations, or when to prefer this over threads_delete_post.

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