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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Get repository status' implies a read-only operation, but it doesn't specify whether it requires authentication, what the output format is (e.g., text summary, structured data), or if there are rate limits. The description lacks details on behavioral traits beyond the basic action.

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 extremely concise with a single sentence 'Get repository status', which is front-loaded and wastes no words. It efficiently conveys the core purpose without unnecessary elaboration, making it easy to scan and understand quickly.

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 tool's complexity (a Git operation with no annotations and no output schema), the description is incomplete. It doesn't explain what 'status' includes, the return format, or error conditions. For a tool that likely outputs detailed repository state information, more context is needed to guide effective use by an AI 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?

The input schema has 100% description coverage, with the 'path' parameter documented as 'Repository path'. The description doesn't add any meaning beyond this, such as clarifying path formats (e.g., absolute vs. relative) or examples. With high schema coverage, the baseline score of 3 is appropriate as the schema handles the parameter documentation adequately.

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 'Get repository status' clearly states the verb ('Get') and resource ('repository status'), making the purpose understandable. However, it's somewhat vague about what 'status' specifically entails (e.g., staged changes, untracked files, branch info) and doesn't differentiate from sibling tools like 'git_branch_list' or 'git_add', which might overlap in providing status-related information.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an initialized repository), exclusions, or comparisons to siblings like 'git_branch_list' for branch-specific status. Usage is implied from the name but not explicitly stated.

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