lol-summoner-renewal

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 adds context by specifying it's for 'renewing' data via RiotAPI, which suggests it might fetch fresh data or update a cache, aligning with the non-idempotent hint. However, it doesn't detail rate limits, authentication needs, or what 'renew' entails beyond the annotations, leaving some behavioral aspects unclear.

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 concise with two sentences that directly state the purpose and usage guidelines. It's front-loaded with the main action and avoids unnecessary details, though the second sentence could be slightly more specific about 'next functions' to improve clarity without adding bulk.

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 tool's complexity (3 required parameters, no output schema) and rich annotations, the description is mostly complete. It covers purpose and critical usage order, but lacks details on what 'renew' means operationally (e.g., caching behavior, response format) and doesn't reference sibling tools explicitly, which could enhance context for an AI agent.

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 input schema has 100% description coverage, clearly documenting all three parameters (game_name, tag_line, region) with examples and enum values. The description doesn't add any parameter-specific information beyond what the schema provides, so it meets the baseline of 3 for high schema coverage without extra value.

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 action ('Renew the summoner's data') and resource ('OP.GG through RiotAPI'), making the purpose understandable. However, it doesn't explicitly differentiate from sibling tools like 'lol-summoner-search' or 'lol-summoner-game-history', which likely handle related summoner data operations, leaving some ambiguity about unique scope.

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 explicit usage guidance: 'When you retrieve summoner data, you *must* always call this function first, and then call the next functions.' This clearly indicates a prerequisite order and implies alternatives (the 'next functions'), though it doesn't name specific sibling tools, it strongly guides when to use this tool versus others.

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