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

Annotations already declare readOnly, idempotent, non-destructive, closed-world behavior, so the safety profile is covered. The description adds genuinely new context: the result shape (dated collection links and original-recording timestamps), the searchable-field limitation, and the caveat that clip IDs are opaque and collection links do not open an individual clip.

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 purpose is front-loaded and the following sentences each add a distinct caveat (return shape, non-transcript scope, opaque IDs). Five dense sentences are justified, though the 'differs from the website transcript search' clause could be tightened.

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 helpfully explains what is returned and what is not, plus notable limitations. It falls short only on parameter behavior, which is undocumented in both schema and description.

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% across 5 parameters, so the description carries the full burden. It only loosely gestures at topic/date labels ('only reviewed topic/date labels are searchable') while the required 'query' matching semantics, 'limit' bounds, and date-range behavior are left unexplained, so it does not compensate for the coverage gap.

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 and resource ('Search historical Moneytalk clip metadata') and clarifies scope by negation ('not transcripts or current financial advice'). It does not explicitly name or contrast with the siblings get_moneytalk_clip and list_moneytalk_episodes, so it stops short of full sibling differentiation.

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?

It distinguishes this metadata search from 'the website transcript search' and warns that only reviewed topic/date labels are searchable, which is useful when-to-use context. However, it never states when to prefer this over get_moneytalk_clip or list_moneytalk_episodes, leaving sibling routing to inference.

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