Create an application in Hostman

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

With annotations present (readOnlyHint=false, destructiveHint=false), the burden on the description is lower, but it adds no behavioral context beyond the creation action. It does not disclose side effects, permissions, rate limits, or what happens on failure.

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 concise sentence without wasted words. However, given the tool's complexity (16 parameters), it could include more value without being overly verbose. It balances efficiency with a clear core statement.

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?

The tool is complex (16 params, 11 required, no output schema), but the description is extremely short. It does not explain the return value, error handling, or any post-creation behavior, leaving the agent with insufficient context for a complete understanding.

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 baseline is 3. The description adds minimal param-related insight (only 'automatic detection of project parameters'), which does not significantly enhance understanding beyond the schema's detailed per-parameter descriptions.

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 verb 'creates', the resource 'an application in Hostman', and adds a distinctive feature 'with automatic detection of project parameters', which differentiates it from sibling tools that handle other resources like VCS providers or databases.

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 implies usage for creating applications but does not explicitly specify when to use this tool versus alternatives or provide any 'when-not-to-use' guidance. It relies on the context of sibling names to indicate its purpose.

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