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

With no annotations provided, the description carries full burden for behavioral disclosure. 'Create a new application' implies a write/mutation operation but doesn't specify permissions needed, whether this is idempotent, what happens on duplicate names, or what the response contains. This leaves significant behavioral gaps for a creation 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 extremely concise at just three words, with no wasted language. However, this brevity comes at the cost of being under-specified rather than efficiently informative, as it lacks necessary context for proper tool understanding.

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 creation tool with no annotations and no output schema, the description is inadequate. It doesn't explain what constitutes an 'application' in this system, what happens after creation, or provide any behavioral context. The 100% schema coverage helps with parameters but doesn't compensate for the missing operational context.

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 fully documents all three parameters. The description adds no parameter information beyond what's already in the structured schema, meeting the baseline expectation but not providing additional semantic context about how parameters interact or their business meaning.

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 'Create a new application' is a tautology that merely restates the tool name and title without adding specificity. It doesn't explain what an 'application' means in this context or what fields are involved, though it does include the basic verb+resource structure.

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 is provided about when to use this tool versus alternatives like 'update_application' or 'get_application'. The description doesn't mention prerequisites, context, or exclusions, leaving the agent with no usage direction beyond the obvious creation intent.

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