Get backlinks for a specific post

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

Expands beyond the readOnlyHint annotation by detailing pagination, exclusion of archived/WIP posts, and ordering by newest references first, providing useful behavioral context.

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?

Two concise sentences with no redundancy, front-loading key information about retrieval, exclusions, and ordering.

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?

Describes the list content and ordering well, but lacks details on return fields or structure since no output schema is provided, leaving some ambiguity.

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; the description adds context for pagination but does not significantly enhance parameter understanding beyond what the schema provides.

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?

Clearly states it retrieves a paginated list of posts referencing a specified post, including exclusions and ordering, which distinguishes it from sibling tools like esa_get_post or esa_search_posts.

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?

Implies when to use (to find backlinks of a post) but lacks explicit alternatives or when not to use, such as comparing to esa_search_posts for content-based queries.

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