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

With no annotations, the description carries the full behavioral burden. It usefully discloses that both passages are returned whether or not a connection is found, which goes beyond the tool name. However, it does not state that this is a read-only lookup, how missing connections are represented, or what kinds of connection values might appear.

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 short sentences with no filler. It front-loads the core question and immediately provides the key behavioral guarantee, so every sentence earns its place.

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 is simple and an output schema is present, which lowers the burden of describing return values. Still, the description leaves the translation parameter unexplained and does not disambiguate from the similar sibling get_connections, making the definition adequate but not 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 description coverage is 0%, so the description must compensate for bare parameter names. It implicitly maps source and target to 'these two verses,' but it gives no format, example, or additional meaning for those parameters, and it entirely ignores the translation parameter despite that parameter having no schema description.

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 a specific lookup: whether a recorded connection exists between two verses and what kind it is. It stands apart from the plural sibling get_connections by describing a pairwise two-verse relationship, and it adds the useful guarantee that it returns both passages either way.

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 usage context is implied: use this when you need to check for a connection between exactly two verses. However, it does not explicitly state when not to use it, nor does it mention alternatives like get_connections or find_path, so an agent must infer the right scenario from context.

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