get_default_branch_protection

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

With no annotations provided, the description reveals an important behavioral trait: requires admin and falls back to 'unknown' on failure. This adds meaningful context beyond the schema, although it does not describe the return format or any side effects.

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, well-structured sentence that conveys the core purpose and key caveat without redundancy. It is highly concise and front-loads the main action.

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?

The description covers the basic purpose and the admin/fallback behavior, but it lacks essential context such as the format of `owner_repo`, the exact structure of the returned status, and any additional constraints. For a simple tool with no output schema, this leaves some gaps.

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 0%, and the description does not explain the `owner_repo` parameter format or semantics beyond the name itself. The agent may not know whether to use 'owner/repo' or another format, so the description fails to compensate for the lack of schema details.

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 specifies the tool's function: retrieving branch protection status for the default branch. It is specific and distinct from sibling tools that deal with branches, diffs, or PRs, clearly indicating what resource and action are involved.

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?

It provides a contextual cue (requires admin) but does not explicitly state when to use this tool versus alternatives or when not to use it. The purpose is clear enough that an agent could infer usage, but there is no direct guidance on alternatives.

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