Reply to Comment

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

The descriptions implies a write operation (replying creates a comment), but annotations only include destructiveHint=false and no readOnlyHint. The description doesn't add details about permissions, side effects, or what happens to the thread. It is minimally transparent but not misleading.

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, concise sentence that immediately conveys the tool's function. It contains no filler or redundant information, scoring high on efficiency.

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 2-parameter tool with a full input schema and an output schema, the description is sufficient. It clearly states the operation and scope, though it could mention that it's a mutating action. Still, the context is complete enough for an agent to select and invoke it correctly.

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 schema already provides full descriptions for both parameters (comment_id and body), covering type, format (Markdown), and meaning. The description doesn't add any additional semantic value beyond what the schema states. Baseline of 3 is appropriate.

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 identifies the action ('Reply'), the resource ('existing comment thread'), and the context ('on a Confluence page'). This distinguishes it from the sibling tool 'confluence_add_comment', which presumably adds a new top-level comment, by specifying 'existing' thread.

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 phrase 'existing comment thread' implies this tool is for replies, not for creating new top-level comments. However, it does not explicitly name alternatives or provide when-not-to-use guidance. The context is clear but lacks explicit exclusions.

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