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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety and idempotency profile is fully covered structurally. The description adds only that the result includes transliteration and English, which is modest output-content context; it says nothing about error behavior for an invalid id or response shape.

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 first sentence is fine, but the second is an unfocused enumeration of unrelated features ('daily shabad, plans, search, Ang and shabad lookup; whole books') that consumes space without telling the agent anything about calling this tool. It is padding rather than concision.

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 no output schema, the description does usefully signal that transliteration and English are returned, which is the one piece of return-value context the agent gets. However, it omits anything about the shape of the returned shabad (verses, lines, ordering) and the stray toolset enumeration dilutes rather than completes the picture.

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 'id' is already documented as 'A BaniDB shabad ID.' The description's 'by BaniDB id' merely restates the schema and adds no format, range, or validity detail beyond it. Baseline 3 applies since the schema carries the burden.

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 first sentence names the resource (a whole shabad) and its retrieval key (BaniDB id) plus the output content, so the core purpose is discernible, but it is phrased as a title-like noun clause rather than a verb+resource statement. It does nothing to distinguish this tool from siblings such as get_ang or search_readings.

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 guidance on when to use this tool versus get_ang, get_reading, or search_readings. The trailing clause ('daily shabad, plans, search, Ang and shabad lookup; whole books from the Library') reads as a catalog of the entire toolset and could actively mislead an agent into thinking this tool also serves search, Ang, or book-reading requests.

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