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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the safety profile is covered. The description adds a little context with "line by line" and "read a passage at a time," implying the return is an incremental passage rather than a whole book, but it says nothing about output shape or limits.

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?

It is brief, but the sentences are wasteful: the title is echoed and the second half enumerates capabilities of the whole Talmud suite (search, original text lookup, whole books) rather than this tool, which misleads rather than informs.

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 one-parameter read tool with no output schema, the description should at minimum say what a call returns (a passage, verse lines, plan steps). Instead it fills the space with sibling-tool capability blurbs, leaving the agent without a clear picture of the result.

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 fully documented in the schema (including example plan names like "japji"). The description adds no syntax or format detail beyond what the schema already provides, 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 description largely restates the title ("One reading or plan, line by line") and then lists domain-wide capabilities ("daily readings, plans, search and original text lookup; whole books") that belong to the sibling tools rather than this one. It never states plainly that it fetches a single reading/plan by id, and it does not distinguish itself from talmud_get_today, talmud_get_card, or talmud_get_talmud_text.

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 when-to-use guidance and no routing away from alternatives such as talmud_get_today or talmud_read_book. The only soft hint is the id's provenance, which lives in the schema, not the description.

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