app_clip_default_experiences_create_instance

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

No annotations are provided, so the description carries the full behavioral burden and fails. It discloses nothing about auth requirements, side effects, or what a successful create yields — only a pointer to the schema envelope, which is not behavioral context.

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?

It is short but wasteful, redundantly repeating 'POST /v1/appClipDefaultExperiences' twice and leading with a route rather than a purpose statement. It is under-specified rather than genuinely concise.

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 complex create endpoint with a nested JSON:API envelope and no output schema, the description is inadequate. It neither explains the created resource nor provides usable invocation context, leaving the agent reliant on the name and schema alone.

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 100% and there is a single 'body' parameter, so the schema already documents it. The description merely echoes the same component name the schema already references, adding no real semantic value; 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?

The description only restates the HTTP endpoint ('POST /v1/appClipDefaultExperiences') rather than stating in plain language that it creates an app clip default experience. It gives no differentiation from close siblings like app_clip_advanced_experiences_create_instance or app_clip_default_experience_localizations_create_instance.

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 guidance on when to use this tool versus alternatives or when not to use it. It gives no prerequisites (e.g., needing an existing App Clip) or ordering constraints. The agent must infer everything from the name.

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