reading_reply_to_annotation

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

The description implies a write operation but does not disclose behavioral traits like side effects, permission requirements, or what happens when parentId is invalid. No annotations provided beyond title, so the description carries the full burden and falls short.

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, which is appropriately brief for a straightforward tool, though it could benefit from structured bullet points or a clearer explanation of parameters.

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 8 parameters with no param-level documentation and no output schema, the description is insufficient. It fails to explain the role of key optional parameters or the required parentId and note, leaving the agent to guess usage.

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?

With 0% schema description coverage, the description adds no meaning to any of the 8 parameters. It mentions 'parentId' implicitly but does not name the parameter or explain others like kind, mood, tags, quote, etc.

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 action (attach a reply) and the resource (under an existing annotation), distinguishing it from sibling tools like reading_annotate_passage (which creates new annotations) and reading_list_annotations (which lists).

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 on when to use this tool versus alternatives, such as reading_annotate_passage for creating new annotations. No exclusions or prerequisites mentioned.

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