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

Annotations already cover the safety profile (readOnlyHint, idempotentHint, destructiveHint=false, openWorldHint=false), so the description only needs to add context. It adds the 'All curated' scoping notion but nothing about the shape or volume of the list, and its second sentence advertises unrelated capabilities, diluting rather than clarifying behavior.

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 merely repeats the app name and title, and the second is a run-on catalog of the entire product rather than a front-loaded statement of this tool's output. Short, but neither sentence is well targeted at the specific operation.

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 no-param read-only list, the description still leaves the agent unsure what a 'reading' or 'plan' actually is, whether the result is paginated, and how it differs from the other Gita list/lookup tools. With rich annotations and no output schema, the description needed to carry more scope information and does not.

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?

The tool takes zero parameters and the schema is an empty object, so there is no parameter semantics to explain; baseline of 4 applies. The description adds no misleading parameter expectations.

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 title and opening sentence state a recognizable verb+resource (list all curated daily readings and plans), and 'All' implies full-list scope versus the single-item siblings gita_get_today/gita_get_reading. However, the second sentence describes app-wide capabilities (daily verses, search, verse lookup, whole books, reading a passage) that belong to sibling tools, blurring what this specific tool returns.

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?

No indication of when to choose this over gita_get_today, gita_list_books, or gita_search_readings. The trailing clause about 'search and verse lookup' and 'read a passage at a time' actively points at other tools without naming them, leaving the agent to guess the selection criteria.

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