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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is fully covered. The description adds meaningful context by noting result ordering (best match first), but says nothing about result count, pagination, 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 purpose is front-loaded, but the lead sentence duplicates the title exactly, and the trailing sentence ('Talmud: daily readings, plans, search and original text lookup; whole books from the Library, read a passage at a time') is a garbled list that mixes content domains with an instruction fragment, reducing clarity.

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 one documented parameter, no output schema, and rich annotations, the definition is minimally sufficient to call the tool. It still leaves the return format, result volume, and scope relative to sibling retrieval tools unstated, which an agent would want before choosing it.

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% and the single q parameter already includes an example ('kindness or Shabbat'). The description adds no syntax, matching, or query-format detail beyond what the schema 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 first sentence states a specific verb (search) and resource (curated readings) plus a ranking behavior (best match first). However, it merely repeats the title verbatim, and the second sentence drifts into content-domain coverage (Talmud, plans, books) rather than distinguishing this tool from siblings like get_talmud_text or read_book.

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 guidance on when to use this search tool versus the many siblings (list_readings, get_reading, read_book, get_talmud_text). The second clause implies broad content coverage but never states a condition that selects this tool over the alternatives.

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