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

The annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the safety profile is fully covered externally. The description adds nothing behavioral beyond that — no note on return shape, whether remote content is fetched, or what 'line by line' implies for output.

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 two sentences largely restate the tool name and title, and the trailing clause ('daily verses, plans, search and verse lookup; whole books from the Library') describes the whole app rather than this tool. This is clutter rather than informative brevity.

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 single-parameter read tool with rich annotations and full schema coverage, the definition is minimally adequate. However, it never clarifies how a 'reading' differs from a 'card', 'chapter', or 'today', so the agent lacks the context needed to confidently pick this tool over its siblings.

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 'id' parameter is well documented in the schema with concrete examples ('japji', 'The Gita in 18 Days'). The description adds no parameter meaning of its own, 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 implies retrieving a single reading or plan and even hints at the format ('line by line'), so the basic purpose is inferable. But it never states the verb cleanly and does not distinguish this tool from close siblings like gita_get_today, gita_get_card, or gita_read_book, leaving the agent to guess which one to call.

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 guidance, no mention of alternatives, and no exclusions. The schema notes the id comes from list_readings, but the description itself provides no routing logic between this tool and its many sibling readers.

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