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. It states the action ('stages changes') but does not explain what 'staging' entails (e.g., adding files to the index, partial commits), potential side effects (e.g., overwriting previous stages), authentication needs (implied by 'user' and 'password' params but not described), or error conditions. This leaves significant gaps in understanding the tool's behavior.

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, direct sentence: 'Stages changes in a Git repository.' It is front-loaded with the core action and resource, with no unnecessary words or redundancy. This makes it highly efficient and easy to parse, earning a top score for conciseness.

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 Git operations, no annotations, and no output schema, the description is incomplete. It does not explain what 'staging' means in Git context, what the tool returns (e.g., success status, staged file list), or how it interacts with other Git tools in the sibling list. For a mutation tool with behavioral nuances, this minimal description fails to provide adequate context for safe and effective use.

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 clear documentation for 'repo', 'user', and 'password'. The description does not add any meaning beyond the schema, such as explaining what 'staging' involves for these parameters or their interdependencies. Since schema coverage is high, the baseline score of 3 is appropriate, as the description does not compensate but also does not detract.

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 'Stages changes in a Git repository' clearly states the action (stages) and resource (changes in a Git repository), making the purpose understandable. However, it does not differentiate from sibling tools like 'pushRepo' or 'gitPullRepo', which also operate on Git repositories, leaving ambiguity about when to use this specific tool versus others.

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 does not mention prerequisites (e.g., after making local changes, before committing), exclusions, or related tools like 'pushRepo' for pushing staged changes. This lack of context makes it unclear in what workflow step this tool fits.

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