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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so safety is covered. The description adds real value beyond them: it explains that the raw `image` is the publisher-stored URL (null when unset, even though a generated cover may display) and that values round-trip with create_collection/add_verse on the authenticated server. It omits any note on item limits, pagination, or read-side auth.

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?

Purpose is front-loaded in the first sentence and the image caveat follows in a compact block. The image explanation is slightly repetitive (stored vs computed display image stated twice) but each sentence carries information an agent would otherwise guess wrong.

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?

With an output schema present, return shape need not be described, and the description focuses on the one genuinely non-obvious field (raw image semantics) plus the parameter source. Nothing critical to calling it is missing, though it stays silent on scale/pagination of returned verses.

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 parameter — and it does, defining collection_id as 'The collection ID (from browse_collections results)', which adds provenance the bare integer schema lacks. It does not specify ID format or validity behavior, so it is not fully compensating.

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 and resource with scope: 'Get full details of a published collection including all verse text, references, and topics.' This implicitly separates it from browse_collections (list-level) and get_collection_metrics (aggregates), though it never names those siblings explicitly.

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?

Usage is implied rather than stated — the note that collection_id comes 'from browse_collections results' sketches a browse-then-detail workflow, but there is no explicit when-to-use, when-not, or named alternative. Adequate but leaves the agent to infer the routing.

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