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

With no annotations, the description carries the full burden and does well: it discloses atomicity, the writable constraint, authentication needs, and parameter passing conventions (body, path/query, aliases). It does not mention return values or error behavior, but the added context is substantial.

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 concise and front-loaded with the main purpose. There is slight redundancy ('Update multiple tasks' appears twice conceptually), but each sentence adds useful detail. It is appropriately sized for the tool's complexity.

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?

The description covers request construction, authentication, atomicity, and permission requirements, which is good for a low-level proxy. However, with no output schema, it omits return-value semantics and does not explain the structure of the bulk payload beyond 'JSON request payload'. These gaps prevent full completeness.

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 has one 'body' property with a vague description, and the description attempts to add meaning by explaining body, path/query parameters, and aliases. However, it contradicts the schema by calling body 'optional' while schema requires it, and suggests top-level fields that additionalProperties=false disallows. This is confusing and harms usability.

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 multiple tasks' and identifies the exact REST endpoint 'POST /tasks/bulk', making the tool's purpose unmistakable. This differentiates it from sibling tools like vikunja_update_task (single task) and other vk_post_tasks_* that create tasks.

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 gives clear context: use for multiple tasks atomically, requires user-writable tasks, and authentication is required. It implies 'when you need to update more than one task' but does not explicitly mention alternatives or when not to use, so it lacks explicit exclusion guidance.

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