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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so safety and idempotency are covered. The description adds the pagination trait that following 'next' continues across chapters, a modest behavioral detail beyond the annotations, but says nothing about response shape or how the book/passage traversal terminates.

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 duplicate the title verbatim, and the third is a run-on blurb listing capabilities (daily readings, plans, search, original text lookup) that belong to other sibling tools rather than this one, muddying scope. Structure is front-loaded but contains recycled and off-tool content.

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 full schema coverage and a complete annotation set for a simple read tool, the description is adequate to call the tool correctly. It falls short only on sibling differentiation and return/traversal expectations, which is a moderate gap rather than a blocking one.

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 book, section, n, and ref (including the 'ref overrides section and n' rule) are fully documented in the schema itself. The description adds no parameter-level meaning and only alludes to 'a passage at a time', 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 name plus 'whole books from the Library, read a passage at a time' conveys that this reads a book passage by passage, but the description leads with the 'Talmud Scroller' branding and never states the core action as a clean verb+resource. It does not distinguish this tool from close siblings like talmud_get_reading, talmud_get_talmud_text, or talmud_list_readings, so an agent still has to guess which one to reach for.

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?

'Follow next for the next passage; it carries on into the next chapter' does describe the sequential-reading workflow, which is real usage guidance for chaining calls. However, there is no explicit when-to-use versus the sibling reading/text tools, and the trailing feature list (daily readings, plans, search) blurs rather than sharpens the usage context.

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