word_reply_comment

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

Annotations indicate the tool is not read-only (readOnlyHint=false) and not destructive (destructiveHint=false), but the description adds no behavioral insights beyond that. There is no mention of side effects, permissions, or operational nuances, leaving the agent under-informed about mutational behavior.

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 extremely concise (one sentence), but it lacks critical information about the tool's function and parameters. Conciseness at the expense of completeness is not beneficial; the description is under-specified.

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 tool has 6 parameters (3 required) and no output schema, the description should provide more context about its operation. The alias relationship to word_reply_to_comment is noted, but without referencing that tool's description, the agent lacks complete understanding. The description is insufficiently contextual for effective use.

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 0%, and the tool description does not explain any of the 6 parameters (file_path, comment_id, reply_text, author, output_path, auto_resolve). The agent must infer parameter meaning from names alone, which is insufficient for many optional parameters. No value is added beyond the schema.

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 it is a backward-compatible alias for word_reply_to_comment, indicating the tool's function by reference. However, it does not explicitly describe what the tool does (e.g., reply to a comment), relying on the agent's knowledge of the target tool. The name suggests the action, but the description lacks direct purpose 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 guidance is provided on when to use this tool versus alternatives, such as word_reply_to_comment or other comment-related tools. The description only notes backward compatibility, which implies identical usage but offers no explicit direction.

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