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

Despite no annotations, the description discloses key behaviors: authentication is required, the user needs write access, the payload goes in an optional body field, and parameters support camelCase/snake_case aliases. This is strong coverage for a raw proxy, though it omits return format or error handling.

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 mostly concise and front-loaded, but it repeats 'Update an existing task comment' twice. Minor redundancy, yet overall efficient and easy to scan.

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 raw proxy with no annotations or output schema, the description provides some essential context (auth, access level, parameter style), but it does not specify what fields the body payload should contain, what the response looks like, or error conditions. This leaves gaps for an agent needing to construct a valid update request.

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 coverage is 100%, but the description adds meaningful usage context: 'Pass the JSON request payload in the optional body field' and 'Path and query parameters are top-level fields.' It also clarifies that aliases are accepted, which is not evident from the schema alone.

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 'Update an existing task comment' and identifies the exact REST endpoint POST /tasks/{taskID}/comments/{commentID}. This distinguishes it from sibling tools like vikunja_create_task_comment and vikunja_list_task_comments.

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 explicit guidance on when to use this tool versus alternatives. It mentions preconditions like write access and authentication, but does not contrast with create/list/delete comment tools or state when this tool is inappropriate.

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