Create feature branch

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

With no annotations provided, the description bears full burden for behavioral disclosure. It mentions 'validating safety constraints' but does not specify what those constraints are, what happens if the branch already exists, or whether the branch is checked out locally. This lack of detail leaves the agent unaware of potential side effects or failure conditions.

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, 13-word sentence that immediately communicates the core purpose. No extraneous information. Every word earns its place.

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 on behavior, such as whether the branch is automatically checked out, how safety constraints are validated, and what success/failure looks like. The current description is insufficient for a tool with 4 parameters and no structured behavioral hints.

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?

All four parameters have descriptions in the input schema (100% coverage), so the description adds limited new semantic value. The description reinforces the baseBranch parameter by saying 'from the base branch', but does not go beyond what the schema already provides. A score of 3 reflects adequate but not enhanced understanding.

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 'Create', the resource 'feature branch', and the action 'from the base branch after validating safety constraints'. It distinguishes from sibling tools like github_create_pull_request and github_push_feature_branch by focusing on local branch creation and safety validation.

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 explicitly state when to use this tool versus alternatives. It implies use for creating a new feature branch but lacks guidance on scenarios where sibling tools like github_prepare_feature_workflow might be more appropriate, nor does it mention prerequisites or when not to use this tool.

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