Create App Configuration

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

Annotations already indicate non-read-only and non-destructive nature. The description adds that it returns HTTP 201 and the created object, and lists the required parameters. However, it does not disclose side effects or specific behaviors beyond creation, which is partially covered by annotations.

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 four sentences with some redundancy (repeats 'App Marketplace records'). It includes essential details like required parameters and API endpoint, but could be more concise. Adequate but not optimized.

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?

Given the tool's complexity (8 parameters, nested objects, no output schema) and the presence of sibling tools, the description provides basic context (endpoint, return status) but lacks explanation of parameter interdependencies, error handling, or response structure. It meets minimum viability but has clear gaps.

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?

Input schema has 100% coverage with descriptions for all parameters. The description merely repeats the required parameter names without adding semantic meaning, such as explaining the relationship between 'applies_to_all_projects' and 'project_ids' or the structure of 'instance_configuration'. Baseline score of 3 is appropriate.

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 creates a new app configuration for a project, and the mention of 'App Marketplace records' provides domain context. It distinguishes from sibling CRUD tools by the verb 'create', but the repetition of 'Creates a new App Marketplace records' is slightly redundant.

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 description only says 'Use this to create a new App Marketplace records' without explaining when to use this tool versus siblings like update_app_configuration or list_app_configurations. No guidance on prerequisites or conditions.

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