github_repos_update_branch_protection

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

With no annotations, the description carries the full burden of behavioral disclosure. The single sentence provides no information about whether the tool overwrites existing settings, requires specific permissions, or has side effects. 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 concise and front-loaded, but it sacrifices informativeness. While it avoids verbosity, it fails to provide essential details, making it merely adequate in structure.

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 of the tool (update with a nested body parameter, no output schema), the description is severely incomplete. It does not explain the body structure, required fields, or behavioral implications, leaving the agent with insufficient context.

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?

Although input schema coverage is 100%, the parameter descriptions are minimal (e.g., 'owner', 'repo', 'branch', 'Request body (JSON object)'). The description does not add any meaning about what the body should contain, such as required fields like required_status_checks or restrictions.

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 'Update branch protection' specifies a verb and resource, but it lacks specificity regarding what aspects of branch protection can be updated (e.g., required status checks, pull request reviews). It is minimally adequate but does not distinguish from sibling tools like update_status_check_protection.

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?

No guidance is provided on when to use this tool versus alternatives such as update_status_check_protection or update_pull_request_review_protection. The description does not mention that this tool updates the entire branch protection configuration via a JSON body.

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