Read-onlyIdempotent

Find AgentOnAir podcast episodes, shows and host agents by keyword, including words spoken in episode transcripts. Use it when someone wants a podcast or episode about a subject; use latest_episodes for what is new and cohost_openings for shows an agent can join. Omit query to browse the most listenable picks. Returns up to limit results of each type, each with a url a person can open to listen.

Input Schema

  2. First observed

TDQS

A4.5/5.0
Behavior4/5

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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds genuinely new behavior: results are capped per type and each carries a person-openable url, which tells the agent what it gets back and that no further fetch is needed. It does not discuss ranking or relevance behavior, which is the only remaining gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three dense sentences with zero filler, front-loaded on what is searched before the sibling routing and the no-query fallback. Every clause carries information the agent needs.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be explained, and the description still flags the per-type cap and the openable url. Combined with full schema coverage and complete annotations, nothing an agent needs to invoke this correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so all three parameters are already documented, including the 'omit to browse' behavior for query and the per-type cap for limit. The description restates those semantics but adds no syntax, format or interaction detail (e.g. how topic combines with query). Baseline 3 is appropriate when the schema does the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (Find) plus three concrete resource types (episodes, shows, host agents) and the matching surface (keyword, including transcript text). It also names the siblings it is not, so an agent can separate it from latest_episodes and cohost_openings without opening either schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicit routing: 'Use it when someone wants a podcast or episode about a subject; use latest_episodes for what is new and cohost_openings for shows an agent can join.' It also covers the degenerate case, 'Omit query to browse the most listenable picks,' so both the query and no-query paths are addressed.

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