get_snapshot_at_time

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

No annotations are present, placing full burden on the description. The description only says 'get' and provides no information about what the snapshot contains, how it behaves, or any side effects.

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, efficient sentence with no wasted words. It is appropriately front-loaded, though lacks detail (which is covered by other dimensions).

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?

The tool appears simple with 2 params and an output schema, but the description is too vague to understand what a 'game state snapshot' includes. The presence of many sibling tools and no guidance makes the description insufficient.

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%, and the description only references 'specific game time', leaving match_id undocumented. It does not clarify units for game_time or add semantics beyond the schema.

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 tool retrieves a game state snapshot at a given game time, using a specific verb and resource. However, it does not differentiate from sibling tools like get_stats_at_minute or get_hero_positions that also provide game-related data at a time.

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?

No usage guidance is provided. The description does not mention when to choose this tool over alternatives, nor any exclusions or prerequisites.

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