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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, covering the safety profile. The description adds that reading proceeds passage-by-passage and carries into the next chapter, which is useful sequential-reading context, but no additional details on auth, rate limits, or return format.

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 essentially a restatement of the title and is unclear. The second sentence is a run-on list mixing unrelated features ('daily shabad, plans, search, Ang and shabad lookup') with the actual book-reading capability, hurting front-loading and focus.

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 should explain what a reading returns, but it only says it reads a passage at a time. Annotations cover safety and schema covers parameters, so it is minimally complete but lacks return-format details for a read 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%, so the schema already fully documents all four parameters. The description adds no parameter-specific meaning beyond what the schema provides, making the baseline score of 3 appropriate.

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 states the resource (whole books, a passage at a time) but the first sentence about 'Follow next' is a confusing UI instruction rather than a clear statement of what the tool does. It does not distinguish this tool from siblings like get_reading or get_shabad.

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 explicit when-to-use guidance or alternatives are mentioned. The phrase 'Follow next for the next passage' is an in-tool navigation hint, not a condition for selecting this tool over siblings.

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