github_repos_create_deployment_branch_policy

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

With no annotations, the description should disclose behavioral traits. It only states the action ('Create'), with no mention of side effects (e.g., behavior if policy already exists), required permissions, or idempotency. This is insufficient.

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 sentence without wasted words, but it is under-specified for the tool's complexity. Front-loading the core action is fine, but the brevity sacrifices useful context. Earns its place but is not optimally informative.

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 no annotations, no output schema, and a nested 'body' parameter, the description is incomplete. It fails to explain what the body should contain (policy rules, etc.) and what the response will be, leaving significant gaps for the agent.

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% but each parameter description is minimal (e.g., 'owner', 'repo'). The tool description adds no additional meaning, so baseline of 3 is appropriate; it neither harms nor helps beyond the schema.

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 'Create a deployment branch policy' clearly states the verb (Create) and resource (deployment branch policy). However, among sibling tools like update, delete, and get deployment branch policies, it does not differentiate when to use create versus update, limiting clarity.

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 usage guidelines are provided. The description does not indicate when to use this tool instead of alternatives like update_deployment_branch_policy or list_deployment_branch_policies, leaving the agent without context for correct invocation.

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