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

No annotations provided, yet the description discloses no behavioral traits. Missing: whether replies create threaded conversations, rate limiting, what happens if the parent comment is deleted, or required authentication scope.

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 brief at only four words. While not verbose, it is appropriately structured and front-loaded; however, the extreme brevity contributes to under-specification rather than efficient communication.

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 the rich ecosystem of 40+ sibling tools with overlapping functionality (ig_post_comment, threads_reply, ig_send_message), the description fails to clarify unique aspects, return behavior, or selection criteria needed for correct tool 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 has 100% description coverage for both parameters. The description adds no additional semantic context (e.g., message length limits, comment_id format), meeting the baseline expectation when schema documentation is complete.

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?

States the basic action (reply) and target (comment), but lacks specificity about the Instagram platform context and fails to distinguish from sibling tools like ig_post_comment (which posts top-level comments) or threads_reply.

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?

Provides no guidance on when to use this versus ig_post_comment or other communication tools. Does not mention prerequisites like obtaining the comment_id from ig_get_comments or permissions required.

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