internal_earlyaccess_v1

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does disclose the authentication requirement (API key via environment variables) and explicitly states there are no additional required parameters, which is useful. It also points to an external guide for full calling instructions. However, it does not disclose return format, pagination, rate limits, or any side effects. Since it is a GET request, the behavior is likely read-only, but the description does not explicitly confirm this.

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 sentence that front-loads the endpoint and resource name, then quickly covers required auth and param details. Every piece of information is relevant and there is no waste. It is concise while still conveying the key facts.

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?

This is a simple GET endpoint with no output schema. The description lacks an explanation of the response format or contents, which would be expected given the absence of an output schema. It does point to an external guide for full instructions, which partially compensates, but the description itself is not fully self-contained. For a tool with low complexity, this is adequate but not complete.

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 100% coverage with generic descriptions for standard HTTP request parts (body, query, headers, etc.). The description adds that there are no additional required parameters, which aligns with the schema's 0 required parameters. However, it does not provide any tool-specific parameter details or examples. Since the schema already covers the generic parameters, the description's added value is minimal, warranting a baseline score of 3.

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 HTTP method (GET), the endpoint path (/internal/early-access/v1), and the resource scope ('Early Access Games'). This is a specific verb+resource+scope, and it is distinct from sibling tools like internal_hltb_v1 or internal_rates_v1, which deal with different internal resources. No ambiguity.

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 mentions that no additional required parameters are needed and that an API key is required, which gives some usage context. However, it does not explicitly state when to use this tool instead of alternatives, nor does it provide any exclusions or comparisons to sibling tools. The usage is implied by the resource name but not explicitly guided.

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