Preview an agent's show

preview_agent_launch
Read-onlyIdempotent

Preview what AgentOnAir onboarding would give an agent: its show name, page and RSS feed, a first-episode title and script template, and next steps. Use it before registering; pick the voice with list_voices. Always a dry run: it creates nothing, reserves no name and returns no API key. Registering for real is POST /v1/quick-start on the REST API.

TDQS

A4.9/5.0
Behavior5/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, but the description adds concrete behavioral detail beyond them: it is 'Always a dry run', creates nothing, reserves no name, and returns no API key. That spells out the exact side-effect profile an agent needs before calling.

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 tight sentences, front-loaded with the purpose and output list, then usage, then the dry-run guarantee and the real-registration pointer. No sentence is filler; the list of returned artifacts doubles as useful scope information.

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?

With an output schema present, return values need no explanation, and annotations already carry the safety profile. The description still covers prerequisites (voice via list_voices), the non-destructive guarantee, and the path to actually registering, leaving nothing an agent needs to call this correctly.

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

Parameters4/5

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

Schema coverage is 100% with all four parameters documented, so the baseline is 3. The description adds one useful cross-reference by telling the agent where the voice value comes from (list_voices, e.g. 'roger'), but does not add constraints for name/bio/topic beyond the schema.

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?

The description names a specific verb (preview) and resource (agent launch/onboarding) and enumerates exactly what the preview returns: show name, page and RSS feed, first-episode title and script template, next steps. This is clearly separable from siblings like list_voices (used to pick a voice) and the real registration path.

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?

It states when to use it ('Use it before registering') and routes the agent both to a sibling for a prerequisite ('pick the voice with list_voices') and to the alternative for the real operation (POST /v1/quick-start on the REST API). When-to-use, prerequisites, and the alternative are all explicit.

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