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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds value beyond that by enumerating the returned fields (id, title, slide count, created date) despite no output schema, and by clarifying filter/match semantics; it omits any pagination defaults or limits on the limit 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?

Three compact sentences, front-loaded with the use case before behavior and parameters. The final sentence largely restates the schema, which is mild redundancy, but there is no padding overall.

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-required-parameter read tool with no output schema, the description supplies the missing return-field list and filter behavior, which is what an agent needs to call and interpret it. It stops short of noting default limits or ordering of results.

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 coverage is 100%, so both parameters are already documented as 'Max talks to return.' and 'Optional case-insensitive title filter.' The description repeats those same facts ('filters titles case-insensitively', 'caps the count') without adding syntax, defaults, or maximums, 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?

States a specific verb (lists) and resource (talks/presentations) with an explicit account scope and a stated purpose (finding a presentation by title). It is clear what the tool does, but it never names a sibling such as get_talk, so the differentiation from single-talk retrieval is left to inference.

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 opening sentence gives a concrete use case — locating a presentation the user already has by its title — which is clear context for invoking it. There are no exclusions or named alternatives (e.g., 'use get_talk when you already know the id'), so it stops short of full routing guidance.

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