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

No annotations are provided, so the description carries the full burden. It does disclose that the tool traces a theme's development across covenants, which implies a read-oriented research behavior, but it does not describe the return shape, ordering, default behavior of starting_verse, or any limitation. The transparency is adequate at a high level but has gaps.

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 sentence with no filler, front-loaded with the operation and scope, and followed by clarifying examples. Every part 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?

For a simple two-parameter read tool, the description plus schema is mostly sufficient to invoke it correctly with a theme. However, with no output schema and no annotations, it does not say what the returned chain looks like or when to choose this tool over sibling cross-reference and semantic search tools, so completion is adequate but not strong.

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 100%, and both parameters are documented: theme as a thematic concept and starting_verse as an optional OSIS with a default. The tool description adds thematic examples but no additional parameter syntax or behavior details, so the baseline of 3 applies.

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 a specific verb ('Traces') and resource ('progressive revelation of a biblical doctrine or theme across covenants'), with concrete examples like 'Living Water' and 'Seed of the Woman' that clarify what counts as a theme. It differentiates from generic search tools by emphasizing covenant progression, but it does not explicitly name or distinguish a sibling tool like get_cross_references.

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 phraise 'progressive revelation... across covenants' implied the intended use case, but the description gives no explicit when-to-use or when-not-to-use guidance and does not mention alternatives. An agent has to infer when this is preferred over search_semantic or get_cross_references.

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