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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Create a new task' implies a write/mutation operation but reveals nothing about permissions needed, side effects, error conditions, rate limits, or what happens on success/failure. This is inadequate for a mutation tool with zero annotation coverage.

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—a single three-word phrase—with zero wasted words. It's front-loaded and efficiently communicates the core action, though this brevity comes at the cost of completeness.

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 mutation tool with no annotations and no output schema, the description is completely inadequate. It doesn't explain what the tool returns, error handling, system context, or behavioral traits. The 100% schema coverage helps with parameters but doesn't compensate for the lack of operational context needed for effective tool 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?

The description adds no parameter information beyond what's in the schema. However, schema description coverage is 100%, with clear documentation for all three parameters (title, description, priority including enum values). This meets the baseline of 3 where the schema does the heavy lifting, though the description contributes nothing extra.

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 'Create a new task' is a tautology that merely restates the tool name. It specifies the verb ('create') and resource ('task') but lacks any distinguishing details about what kind of task or system context. Compared to siblings like 'delete_task' and 'update_task_status', it doesn't differentiate scope or functionality beyond the basic action.

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 guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, when-not-to-use scenarios, or how it relates to sibling tools like 'get_task' or 'update_task_status'. There's no implied context or explicit usage instructions.

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