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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the action and HTTP mapping, but fails to mention authentication requirements, side effects, privacy implications (e.g., isPrivate default), or whether the operation is idempotent. This is a write operation, so these details are critical.

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 a single, front-loaded sentence that directly states the action without unnecessary filler. It is appropriately concise for a simple tool, though it could expand on context without losing conciseness.

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?

This is a mutation tool with no annotations and no output schema, so the description must explain expected outcomes or error conditions. It merely says 'post a reply' without describing success behavior, required permissions, or how privacy/visibility works. Given the schema's presence, the description is under-specified for safe autonomous 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?

The input schema already documents all three parameters with complete descriptions (100% coverage), so the baseline is 3. The description adds minimal semantic value beyond the schema, though 'existing comment thread' hints that commentId must be valid, which is already implied by 'Parent comment UUID'.

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 uses the specific verb 'post' and clearly identifies the resource ('a reply' on 'an existing comment thread'), which unambiguously distinguishes it from sibling tools like list_replies (read-only) and update_feedback (modifying feedback). The mapping to POST /reply reinforces the action.

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 description provides no guidance on when to use this tool versus alternatives. It does not mention list_replies as the read counterpart, nor does it state any exclusions or prerequisites (e.g., requiring an existing comment thread). There is no context to help an agent decide between this and update_feedback.

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