install_app_instance

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

No annotations are present, so the description must fully disclose behavioral traits. It only states 'Install... into a workspace' without mentioning permissions, side effects, error conditions, or what happens if the app already exists. This is insufficient for a mutation tool.

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 a single sentence with no unnecessary words. It is front-loaded with the core action and purpose, and every part earns its place. Maximum efficiency.

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 complexity (nested object, 4 parameters, no output schema, no annotations), the description is too minimal. It does not explain what happens on success, return values, error scenarios, or prerequisites beyond the get_app hint. The tool needs more contextual information to be fully usable.

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%, so the schema already documents all parameters. The description adds value by mentioning the app's configuration schema, but does not elaborate on parameter semantics beyond what the schema provides. Baseline 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 action (Install) and the resource (app from Prisme.ai store into a workspace). It distinguishes the tool from siblings like get_app or list_apps, but doesn't explicitly mention that it creates an instance, which would elevate it to 5.

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 advises to use get_app first to understand the configuration schema, which provides useful context. However, it lacks explicit when-to-use or when-not-to-use guidance, and no alternatives are mentioned, limiting its helpfulness.

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