update_room_config

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

Discloses key behaviors: only non-None fields updated, ready flags reset on any change, atomic mutation under state_lock, and failure conditions outside pre-game states. No annotations, so description carries full burden and does well.

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?

Structured with clear sections and about 6 sentences. Could be slightly tighter, but overall well-organized and not overly verbose.

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?

Despite good usage and transparency, missing parameter explanations and no output schema make it incomplete for an agent to correctly invoke the tool, especially with 7 parameters.

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 has zero descriptions (0% coverage) and description does not explain individual parameters like scenario, team_assignment, etc. It only states that only passed (non-None) fields are updated, leaving parameter meaning unclear.

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?

Clearly states 'tweak room config while still in the lobby' with specific verb 'tweak' and resource 'room config', distinguishing it from siblings like create_room, join_room, preview_room, and set_ready.

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?

Specifies 'Host-only' and 'while still in the lobby', and notes it fails outside pre-game states (COUNTING_DOWN, IN_GAME, FINISHED). However, it does not explicitly state when not to use or suggest alternatives.

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