Add a VCS provider

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

The description matches the annotations (readOnlyHint=false, destructiveHint=false). It adds behavioral context beyond annotations by detailing authentication error handling in the parameter descriptions (e.g., asking the user for credentials on authorization errors). This helps the agent anticipate the tool's interaction patterns.

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 that efficiently conveys the core functionality. Every word is necessary and there is no extraneous content.

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 (4 parameters, no output schema) and the detailed schema, the description is mostly sufficient. However, it lacks information about the expected result (e.g., returns provider ID or status) and potential side effects (openWorldHint suggests possible impacts). The description could be slightly more complete.

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 provides definitions and constraints for all parameters. The tool description itself adds no parameter-specific meaning; the detailed notes (e.g., automatic URL reading, credential requirements) are part of the schema descriptions. Thus, the description adds marginal value beyond the schema.

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 title and description clearly specify the action (Adds) and the resource (a VCS provider) along with the purpose (to connect Git repositories to Hostman). This distinguishes it from sibling tools like get_vcs_providers that retrieve rather than create.

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 does not provide any guidance on when to use this tool versus alternatives (e.g., other create tools or VCS-related tools). There is no mention of prerequisites or scenarios where another tool would be more appropriate.

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