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

With no annotations, the description carries the full burden. It discloses read-only nature via 'Browse' and 'Returns', notes the registry is public, and mentions filtering capabilities. However, it does not explain result ordering beyond 'recently issued', pagination details, or any rate limits, leaving some behavioral traits undisclosed.

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 two sentences, front-loaded with the core purpose and followed by the two key filters. Every word contributes, with no redundancy or unrelated details.

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 simple read-only browsing tool with three optional parameters and no output schema, the description sufficiently covers what it returns and how to filter. It could mention the limit parameter or explicitly state read-only behavior, but these are already implied or covered by the schema, making it complete enough for the tool's complexity.

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 100% with descriptions for all three parameters. The description adds value by explaining the purpose of publisher_id ('explore all content from a specific publisher') and article_id ('see all licenses issued for a specific article') in natural language, going beyond the schema's bare definitions.

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 identifies the tool as browsing the public Opedd license registry and specifies that it returns recently issued licenses and licensable content. It distinguishes itself from sibling tools by focusing on registry browsing and offering specific filters for publisher_id and article_id.

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 usage context (browse the registry, explore a publisher or article's licenses) but does not explicitly mention alternatives or when not to use this tool compared to siblings like lookup_content or list_feed. It provides useful context but lacks explicit exclusions or alternative guidance.

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