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

With no annotations, the description carries full burden. It discloses the tool is a read operation ('Retrieves') and lists the returned content (description, constraints, examples). It does not mention potential side effects or rate limits, but the behavior is simple and adequately described.

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, clear sentence with no extraneous words. It is front-loaded with the purpose and provides essential detail about the return content.

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 no output schema, the description explains return values ('problem description, constraints, and examples') which is sufficient for a simple retrieval tool. However, it lacks specificity about the exact structure or metadata elements.

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 tool has zero parameters and schema coverage is 100%. According to guidelines, 0 params warrants a baseline of 4. The description adds no parameter info because none exist.

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 verb 'Retrieves', the resource 'today's LeetCode Daily Challenge problem', and specifies the scope ('today's') and content ('complete details, including problem description, constraints, and examples'). It effectively distinguishes from siblings like get_problem (for specific problems) and search_problems.

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 implies usage for retrieving today's challenge but provides no explicit guidance on when to use this tool versus alternatives (e.g., get_problem, search_problems). No when-not-to-use or exclusions are given.

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