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

Annotations already cover the safety profile (readOnly, idempotent, closed-world, non-destructive), so the bar is lower; the description still adds real behavioral context by stating the result is grouped by reading, contains no synthesis, is attributed and dated, and that dates are episode publication dates. It doesn't cover ordering or volume of results, but that is a minor gap given the annotation coverage.

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?

Two tight sentences, front-loaded with what is returned before the caveat about synthesis. Some phrasing ('who-would-push-back read') is idiosyncratic, but nothing is redundant.

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 no output schema, the description has to describe the return shape, and it does: stances grouped by reading, individually attributed and dated, unsynthesized. That is enough for an agent to use the result correctly; only the debate_id parameter and pagination/ordering remain unaddressed.

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 0% for the single required debate_id, so the schema contributes nothing. The description only indirectly signals the parameter's meaning ('one debate'), without explaining the identifier's format or source; a modest 3 for implying scoping but not documenting the parameter.

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?

States a specific verb+resource ('every stance on one debate') and a scoping behavior ('grouped by reading'), which is far more precise than the title alone. It does not name or contrast itself against any sibling (find_perspectives, get_context, trace_evolution), so an agent still has to infer which retrieval tool fits which need.

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?

'No synthesis' and 'raw material for your own who-would-push-back read' imply you use this when you want unprocessed positions rather than an aggregated answer, which is useful implied guidance. However, no alternative is named and no explicit when-to-use/when-not condition is given, leaving the choice among the four siblings to inference.

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