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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=true, covering the safety profile. The description adds only that output is 'for voice' and delivered 'one line at a time,' which is useful behavioral context but does not describe pagination, indexing behavior, or response shape.

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 text begins by redundantly repeating the title, contains a double period, and then spends its remaining length on generic suite-level information rather than tool-specific details. It is short but poorly front-loaded and does not earn its sentences.

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 read-only tool with a rich schema and annotations, the description still fails to explain what a 'card' is or how this tool relates to its close siblings (talmud_get_reading, talmud_get_today). An agent lacks the context needed to choose this tool correctly.

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 schema fully explains all three parameters (n, date, reading) with defaults. The description adds no parameter meaning beyond what the schema provides, so the baseline score of 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 ("Talmud Scroller. Today's reading one line at a time, for voice..") and then appends a generic blurb about the entire Talmud suite. It never defines what a 'card' is or distinguishes this tool from sibling tools like talmud_get_reading or talmud_get_today, so an agent cannot tell what unique resource it 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?

There is no guidance on when to use this tool versus alternatives. The generic suite blurb ("daily readings, plans, search and original text lookup...") applies to many siblings and gives no condition that would select talmud_get_card over talmud_get_reading or talmud_get_today.

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