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. 'Records changes' implies a write operation that creates a commit, but it doesn't specify whether this requires authentication, what happens on failure (e.g., if no changes are staged), or any side effects like modifying repository history. For a mutation tool with zero annotation coverage, this is a significant gap in transparency.

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, efficient sentence that gets straight to the point without unnecessary words. It's appropriately sized for a basic tool explanation, though it could benefit from being more informative given the complexity of Git operations. No structural issues are present.

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 commit operation with 4 parameters), lack of annotations, and no output schema, the description is incomplete. It doesn't cover behavioral aspects like error conditions, return values, or how it interacts with other Git tools. For a mutation tool in a workflow-heavy context like Git, more detail is needed to ensure 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?

Schema description coverage is 0%, so the description must compensate by explaining parameters, but it adds no meaning beyond the schema. It doesn't clarify what 'message' should contain (e.g., commit summary), how 'repo_path' is used, or the purpose of 'gpg_sign' and 'gpg_key_id' for signing commits. With 4 parameters (2 required) and no schema descriptions, this leaves critical usage details undocumented.

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 'Records changes to the repository' clearly states the tool's purpose with a specific verb ('Records') and resource ('changes to the repository'), making it understandable. However, it doesn't explicitly differentiate from sibling tools like git_add (which stages changes) or git_push (which sends changes to remote), leaving some ambiguity about its exact role in the Git workflow.

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 staged changes via git_add), exclusions, or how it relates to siblings like git_push for remote operations. Without this context, users might struggle to apply it correctly in a sequence of Git commands.

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