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

The description states 'Mutating: changes server state' and lists required scopes, adding context beyond the annotations. It aligns with annotations (readOnlyHint=false, idempotentHint=false). It could disclose more about failure conditions (e.g., branch already exists, repo not configured) but provides solid behavioral baseline.

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 concise and well-structured: operation, endpoint, scope, and mutating flag. No filler. It loses one point because the body schema gap is a significant omission that could have been addressed with a brief note about required body fields.

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 create operation with no output schema and an undocumented body, the description is incomplete. It provides the endpoint and scope but leaves the most critical information—what the request body needs to contain—entirely unresolved. An agent cannot reliably call this tool correctly.

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?

The body parameter is described as 'Schema not statically declared — see API docs', providing no semantic meaning. The description does not explain what fields the body should contain (e.g., branch name, source branch), so an agent cannot construct a valid request from the available information.

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 explicitly states 'Create branch' and includes the HTTP endpoint, making the verb and resource clear. However, it doesn't distinguish itself from sibling tools like checkout, pull, or deploy, which are also git operations that interact with branches.

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 indicates this is a mutating POST that requires git:write scope, which implies it should be used when creating a branch. But it doesn't explicitly state when to use it vs alternatives, and there are many git-related sibling tools that could be confused with this one.

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