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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false and destructiveHint=false, so the safety profile is covered. The description adds useful output-content context (Sanskrit, transliteration, English), but says nothing about range handling, size limits, or failure behavior for out-of-range chapters.

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 purpose is front-loaded, but the second clause is a run-on inventory of unrelated app features that does not help an agent invoke this tool; the trailing 'read a passage at a time' is especially ambiguous. Roughly half the text is noise.

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 partially compensates by naming the returned content fields, and annotations cover safety. Still missing are range semantics and edge-case behavior, so it is adequate but not complete for a 2-parameter retrieval tool.

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 required parameters are documented there, including the '47-51' range example, which the description merely repeats. No additional meaning (e.g. how ranges bound the response, or whether verse accepts cross-chapter spans) is provided, so the baseline 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 first sentence gives a concrete verb-less but recognizable resource: a verse or range in Sanskrit with transliteration and English, which is more than a restatement of the name. However the second sentence drifts into describing the whole Bhagavad Gita product (daily verses, plans, search, Library books) rather than this tool, and it never distinguishes get_verse from siblings like get_chapter or 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 explicit when-to-use statement or exclusion. 'verse lookup' and 'read a passage at a time' hint at the use case, but an agent cannot tell from this text when to call get_verse instead of get_chapter or read_book.

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