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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. Beyond that the description adds nothing: no note on invalid-reference behavior, no indication of translation alternatives, and no scoping context for how broad a passage request can be.

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?

One tight fragment with no filler, and the example reference is placed inline where it is immediately useful. It loses a point for being a structural fragment rather than a front-loaded statement of what the tool returns.

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?

No output schema exists, so return values need not be described, and the tool is simple (single required string). Still, the description omits how this differs from get_reading and what happens on a malformed reference, leaving real gaps for an agent choosing among six sibling tools.

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% and the single parameter has its own example ('For example: John 3:16'), so the baseline is 3. The description modestly extends this by listing accepted reference forms (range, chapter, cross-chapter) beyond the schema's verse-only example, but does not frame this as parameter guidance.

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 names the resource (a passage of the World English Bible) and its accepted shapes (verse, range, chapter, cross-chapter, with an example). However, it is a verbless noun phrase that essentially restates the title verbatim, so it never says what the tool actually does, and it does nothing to separate it from sibling read tools such as get_reading.

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, no prerequisites, and no named alternative. With siblings like get_reading and get_today plausibly returning adjacent content, an agent gets no signal about which tool to pick for a given request.

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