Check Steam game for YouTube channel

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

With no annotations provided, the description carries the full burden. It implies a read-only 'check' but does not disclose what constitutes a 'good opportunity', what output is returned, whether any side effects exist, or how the result is computed. This is minimal beyond the annotation-less state.

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 very short—one sentence—which makes it front-loaded and easy to parse. However, it sacrifices substance for brevity; while it states the core purpose, it omits important contextual and usage details. It is not bloated, but it is under-specified.

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 tool with 4 parameters, a likely complex matching algorithm, and no output schema, this description is incomplete. It doesn't explain what the result looks like, how the check is performed, or how region/language affect the outcome. The agent is left without enough context to predict behavior or interpret results.

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 coverage is only 50%: steamUrl and youtubeChannelUrl have descriptions, but region and language do not. The tool description adds no parameter meaning whatsoever, failing to explain the role of region/language or how they influence the opportunity check. It does nothing to compensate for the undocumented parameters.

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 a specific action: checking whether a Steam game is a good fit for a YouTube channel. It uses a clear verb and identifies both resources (game, channel). However, it does not distinguish itself from sibling tools like check_small_youtuber_game_fit, which likely has overlapping functionality.

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 guidance is provided on when to use this tool versus alternatives. The description does not mention any exclusions, prerequisites, or contextual cues that would help an agent choose this tool over the many similar sibling check tools.

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