get_my_designers

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

The description adds valuable context beyond the readOnlyHint annotation by specifying authentication requirements and how the output (designer_id) integrates with other tools. While it doesn't detail rate limits or pagination, it provides meaningful behavioral guidance that enhances the annotation.

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 front-loaded with the core purpose, followed by usage guidance and prerequisites in three efficient sentences. Every sentence adds value without redundancy.

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 read-only tool with no parameters and no output schema, the description is nearly complete—it covers purpose, usage, and authentication. A minor gap is the lack of output format details (e.g., pagination or error handling), but overall it's well-suited to the tool's simplicity.

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?

With 0 parameters and 100% schema coverage, the baseline is 4. The description appropriately notes there are no inputs by not discussing parameters, which aligns with the empty 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 specific action ('List designer profiles'), target resource ('for the authenticated user'), and output details ('designer ID, name, and user ID'). It distinguishes itself from siblings like 'get_my_games' by focusing on designer profiles rather than games.

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 description explicitly states when to use this tool ('Use the designer_id with get_my_games or create_game') and provides prerequisites ('Requires authentication'). It clearly differentiates from alternatives by specifying its output is used as input for other tools.

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