apex_create_app

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

Annotations indicate this is not read-only and not idempotent, but provide little else. The description adds the important behavioral trait that an import session is started and must be finalized with apex_finalize_app(). However, it does not explain the session lifecycle, side effects, or what happens if finalization is skipped.

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 description is two concise sentences, front-loading the primary action and including a necessary follow-up instruction. No redundant words or filler.

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 tool with 10 parameters and a session-based workflow, the description is thin. It mentions the finalize dependency but does not explain what an 'import session' is or how this tool fits into the broader app-creation workflow. The output schema likely provides return values, but the workflow context is incomplete.

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?

All 10 parameters have thorough descriptions in the schema (100% coverage), so the description does not need to repeat parameter details. The description adds no parameter-specific guidance beyond schema, which is acceptable given the high schema coverage.

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 clearly states the tool's action: 'Create a new APEX app and start an import session.' This distinguishes it from siblings like apex_finalize_app, apex_delete_app, and apex_export_app by marking it as the creation step. The verb 'create' and resource 'APEX app' are specific and unambiguous.

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 only usage guidance is 'Call apex_finalize_app() when done,' which implies a sequential workflow but does not explicitly state when to use this tool versus alternatives or any prerequisites. The context suggests this is the initial step in app creation, but exclusions and alternative selection criteria are absent.

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