lichess_get_daily_puzzle

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

The description indicates a read operation ('Get'), which suggests no side effects, but lacks details on authentication, rate limits, or any other behavioral traits. No annotations exist to supplement this.

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 sentence that is concise, front-loaded, and contains no unnecessary information. Every word adds value.

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 parameters, no output schema, and a simple purpose, the description is mostly complete. It could mention that it returns only today's puzzle or that the puzzle is from Lichess, but the tool name and context suffice.

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 100% schema coverage, so the description does not need to add parameter meaning. The baseline for no parameters is 4.

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 action ('Get'), the specific resource ('Lichess puzzle of the day'), and includes what is returned ('source game and the solution moves'), which distinguishes it from sibling tools like lichess_get_user or chesscom_get_club.

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 using it to retrieve the daily puzzle, but does not provide explicit when-to-use or when-not-to-use guidance, nor does it mention alternatives like other puzzle sources or historical puzzles.

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