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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed world), so the bar is lower. The description adds one genuinely useful behavioral fact: output is presented 'one line at a time, for voice,' i.e. a TTS-friendly single-line card. It says nothing about pagination via 'n', sequencing, or return shape, so it is modest but non-zero added value.

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 is repetitive and poorly structured: it repeats the title verbatim (with a stray double period) and then lists unrelated features (plans, search, whole-book reading) that belong to the product family, not this tool. It is not front-loaded on what this call actually returns.

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 an unrequired 3-parameter tool with no output schema, the description should clarify what a 'card' is, how 'n' sequences content, and how this differs from get_today/get_reading. Instead it supplies generic marketing text, leaving key call-time questions unanswered.

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 all three parameters (n, date, reading) are documented in the schema itself. The description adds no parameter-level meaning beyond what the schema provides, so the baseline 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 essentially restates the title ('Talmud Scroller. Today's reading one line at a time, for voice') and then appends generic product boilerplate about daily readings, plans, search and library access. It never distinguishes this tool from close siblings like talmud_get_today, talmud_get_reading, talmud_get_talmud_text, or the parallel *_get_card tools in bible/gita/gurbani/lore. It hints at a card-output concept but leaves the actual purpose vague.

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 talmud_get_today, talmud_get_reading, or the get_talmud_text sibling. No conditions, prerequisites, or alternatives are named. The agent is left to guess from the name alone.

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