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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world, so the safety profile is covered. The description adds real behavioral detail — min_weight prunes thinner chapter links and the result is aggregated ('adds up what remains'), and a single summary file is returned. The '[no key]' fragment is too cryptic to count as disclosure.

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 core sentences are front-loaded and information-dense, but 'One summary file. [no key]' are telegraphic fragments whose meaning is unclear and that dilute an otherwise tight description.

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?

An output schema exists so return values need not be described, and the three parameters are largely addressed. What's missing is routing guidance against eight-plus connection/cross-reference siblings and any hint of the required book identifier's format.

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 0%, so the description must carry the load, and it mostly does: min_weight is explained as dropping thin chapter links and summing what remains, and the type enum values are restated. The required 'book' parameter's accepted format is only hinted at ('one King James book'), which holds it back from a 5.

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?

States a specific verb+resource: it returns OT/NT connections for a single King James book. That is distinguishable from siblings like get_connection_graph or get_connection_stats, though the description never explicitly contrasts itself with them.

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?

There is no when-to-use guidance and no named alternative among the many connection/cross-reference siblings. The agent must infer that this is the per-book view while get_connection_graph and get_connection_stats serve other shapes.

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