update_game_title

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

No annotations are provided, so the description must fully disclose behavioral traits. It only says 'update' which implies mutation, but does not mention overwriting behavior, permission requirements, or effects on existing data. For a mutation tool, this lack of detail leaves the agent underinformed about 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, concise sentence that gets straight to the point. It avoids any filler and is front-loaded with the core action and target, making it easy to parse quickly.

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?

For a very simple tool with one parameter and no output schema, the description sufficiently covers what the tool does and where the change happens. It lacks any mention of return behavior or caveats, but given the tool's simplicity, the description is adequate for an agent to understand its role.

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 schema has 0% description coverage for the 'title' parameter, but the tool description clarifies that it refers to the game title, which adds meaning beyond the bare schema. However, it does not provide any additional constraints, format details, or examples that would help an agent construct valid input.

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 the specific verb 'update' with the resource 'game title' and even localizes it to 'Game.ini', making it unmistakable what the tool does. It clearly distinguishes itself from the sibling 'get_game_title' which reads the title.

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 action 'update' implies it should be used to change the game title, but the description does not explicitly state when to use it versus alternatives or any exclusions. It relies on the user to infer the usage from the verb, so it provides only implicit guidance.

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