valorant-meta-characters

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

Annotations indicate this is a read-only, non-destructive, non-idempotent, and closed-world operation. The description doesn't contradict these annotations, but it also adds no behavioral context beyond them. It doesn't explain what 'meta data' includes (e.g., character abilities, roles, patch updates), rate limits, or authentication needs, leaving gaps despite the annotations covering basic safety.

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 extremely concise ('Valorant character meta data'), which is efficient but under-specified. It's front-loaded with the core topic but lacks necessary elaboration to be helpful. While brevity is good, this description sacrifices clarity for conciseness, making it less effective for agent understanding.

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?

Given the lack of an output schema and the tool's domain complexity (gaming meta data), the description is incomplete. It doesn't explain what data is returned (e.g., character lists, stats, patch notes) or how it's structured. With annotations covering only basic hints and no output schema, the description should provide more context about the tool's behavior and results, which it fails to do.

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 description coverage, the schema fully documents the input requirements (none). The description doesn't need to compensate for any parameter gaps, as there are none. It appropriately avoids redundant parameter details, though it could hint at implicit inputs like filtering options if applicable, which it doesn't.

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 'Valorant character meta data' is a tautology that essentially restates the tool name 'valorant-meta-characters'. It lacks a specific verb and doesn't clearly distinguish what operation is performed (e.g., retrieve, list, analyze). While it identifies the resource domain (Valorant characters), it doesn't specify what 'meta data' entails or how it differs from sibling tools like 'valorant-characters-statistics'.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention any context, prerequisites, or exclusions, and fails to differentiate it from sibling tools such as 'valorant-characters-statistics' or 'valorant-agents-composition-with-map'. This leaves the agent with no basis for selecting this tool over others in the same domain.

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