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

Annotations already signal readOnly=false and idempotent=false, and the description adds valuable practical context: calling twice creates two records, and idempotency_key can make a retry safe. This goes beyond the structured annotations by explaining the real consequence of non-idempotence. It does not contradict the annotations.

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 short and front-loaded with the write badge, resource, and endpoint. It has some redundancy ('Create branch' followed by 'Endpoint for creating a new branch'), but it is still compact and every major behavioral point is included without excessive verbosity.

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 detailed input schema, the description adds the essential missing context: the operation is a non-idempotent create with retry guidance. There is no output schema, but this is a simple create endpoint and the key behavioral risk is disclosed. It is complete enough for an agent to invoke it 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?

Schema description coverage is 100%, so the baseline is 3. The tool description mentions idempotency_key in the context of retry safety, but the input schema already fully explains the header behavior, UUID generation, and how to use it. No additional parameter meaning is added beyond what the schema provides.

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 states a specific verb and resource: 'Create branch' and 'Endpoint for creating a new branch.' It also includes the HTTP method and path (POST /branches/), making the operation unmistakable. This clearly distinguishes it from branch update, retrieve, list, and destroy siblings.

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 makes the intended use clear: use this tool when creating a new branch. It does not explicitly name alternatives or say when not to use it, but the create-versus-update/destroy distinction is evident from the verb and endpoint. No misleading exclusions are present.

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