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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds useful context about what each item contains (link, segments, concept cards), but does not disclose ordering, total count, or whether it returns all maamarim, which would be helpful since there is no output schema.

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 description is a single, information-dense sentence with a parenthetical clarification. It is concise and front-loads the content scope, though it could be slightly clearer by explicitly stating the list action at the start.

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 zero-parameter list tool with no output schema, the description is largely complete: it names the source collection and specifies the components of each item. It stops short of describing the return format (e.g., array, pagination) but that is a minor gap given the tool's simplicity.

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?

The tool has zero parameters, so the baseline is 4. The description does not need to compensate for any schema coverage gap, as there are no parameters to describe.

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 identifies the specific resource (maamarim explained in Chassidut In Depth) and its scope (Sefer HaMaamarim 5659 so far), and implies a list of items each with link, segments, and concept cards. It does not use an explicit verb like 'list' but the name and title together make the action clear, and it distinguishes from the sibling get_in_depth tool.

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?

The description offers no guidance on when to use this tool versus alternatives such as get_in_depth or search_lessons. It simply states what the content is, leaving the agent to infer that this is a browsing/list operation with no parameters.

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