get_daily_puzzle

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

No annotations are provided, so the description carries the full burden. It only states the action and resource, but does not disclose any behavioral details such as whether it returns a puzzle object, requires authentication, or has rate limits. For a read-only tool, a simple mention of the response type would improve transparency.

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?

A single, clear sentence with no filler or redundancy. It is front-loaded with the action and resource, making it immediately scannable.

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 simplicity (no params, no output schema), the description is functional but minimal. It does not mention the return format or any additional context like the puzzle's data structure, which could be helpful. However, for a basic fetch tool, it may be sufficient for an agent to understand the core purpose.

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, so the description does not need to add parameter semantics. According to the rubric, a baseline of 4 is appropriate when there are no parameters, and the description adds no unnecessary detail.

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 a specific verb ('Get') and resource ('current daily puzzle from Chess.com'), which distinguishes it from the sibling get_random_puzzle by the 'daily' qualifier. It is unambiguous and immediately actionable.

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 when to use it (when you want the daily puzzle), but it does not explicitly contrast with get_random_puzzle or mention any exclusions. Since there is a similar sibling, explicit guidance would help, but the meaning is still inferred from the word 'daily'.

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