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

There are no annotations, so the description carries the full burden of disclosing behavior. It reveals the cache file location, the local scope, and that listing shows masked sensitive data. However, it does not detail side effects of clearing (e.g., file deletion), the exact format of responses, or how 'expired_only' affects behavior.

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, well-structured sentence that front-loads the core purpose and lists the operations efficiently. It avoids unnecessary words and is easy to parse.

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?

The tool has 3 parameters but no output schema, and the description does not explain the 'expired_only' parameter or adequately specify return formats for each operation. Given the low schema coverage and lack of annotations, the description should provide more detail about inputs and outputs to be fully 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?

Schema coverage is only 33% (only 'command' has a description). The description adds meaning to 'command' by mapping the enum values to operations and clarifies that 'domain' is used for getting tokens. However, it does not explain 'expired_only' at all, leaving a significant gap in parameter understanding.

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 tool's purpose: managing the local L402 token cache at a specific path. It enumerates three specific operations (list, get, clear) and explicitly distinguishes itself from sibling tools like l402_pay and l402_search by focusing on cache management.

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 implies when to use the tool (when you need to manage cached L402 tokens) but provides no explicit when-not-to-use guidance or references to alternatives. The context signals show distinct sibling tools, but the description itself does not mention them or any exclusions.

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