get_player_live_games

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

With no annotations, the description carries the full burden of behavioral disclosure. It only says 'live games' without specifying whether it returns in-progress games only, whether authentication is required, the return format, or any constraints. This is minimal and leaves significant behavioral details unknown.

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 with no redundant words. It is front-loaded with the verb and object, making it easy to scan. However, brevity here sacrifices necessary detail.

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 three required parameters, no output schema, no annotations, and many closely related siblings, the description is far too sparse. It does not explain the return structure, the meaning of 'live games', or how the parameters affect the query, leaving an agent under-equipped to call the tool correctly.

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?

Schema description coverage is 0%, so the description must compensate. It implies that base_time and increment define the 'time control', but it does not explain their units, ranges, or how they interact. An agent cannot infer the exact expected values from this description alone.

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 uses a clear verb 'Get' with a specific resource 'a player's live games' and a qualifier 'for a time control', which conveys the core action. However, it does not differentiate from the sibling 'get_player_current_games', which likely refers to the same or a very similar concept, leaving ambiguity about what 'live' means.

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?

There is no guidance on when to use this tool versus alternatives like get_player_current_games, get_player_games_to_move, or get_player_games_by_month. No context about typical use cases, prerequisites, or exclusions is provided.

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