add_version_milestone

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

With no annotations, the description carries the full burden of disclosing behavioral traits. It only says 'Creates a new version milestone' without mentioning side effects, permissions, reversibility, or return values. 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, concise sentence with no unnecessary words or repetitive content. It is perfectly front-loaded and efficiently communicates the core purpose.

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 lack of annotations and output schema, the description should provide more context about expected inputs, requirements, or response behavior. It does not clarify the roles of projectId versus projectKey, nor what the tool returns after creation. This is a significant gap for a create operation with six parameters.

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 tool description adds no parameter details beyond what the schema already provides. The schema descriptions are minimal but present, and the tool description contributes nothing extra.

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 'Creates a new version milestone' uses a specific verb and resource, clearly distinguishing it from sibling tools like update_version_milestone and delete_version. It states exactly what action is performed and on what entity.

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?

Usage is implied through the verb 'creates', and the sibling list includes update/delete tools, making the tool's role apparent. However, there is no explicit guidance on when to use this tool versus alternatives, nor any mention of prerequisites like projectId or projectKey being required.

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