git_commit

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

With no annotations provided, the description carries the full burden of disclosing behavior. It does mention the confirmation requirement when security.require_confirmation is enabled, which is a useful behavioral caveat. However, it does not disclose other important behaviors such as failure modes (e.g., nothing staged) or the fact that commit mutates repository state beyond what the schema's confirm parameter already implies.

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 exceptionally concise at two sentences, with no redundant wording. The primary purpose is front-loaded, and the confirmation note is placed as a secondary, clearly separated warning.

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 tool is relatively simple, and the output schema exists to explain return values. However, the description omits preconditions such as being inside a Git repository or needing staged changes (unless all_changes=true is set). This makes the description functional but not fully complete for an agent that lacks domain knowledge.

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 coverage is 100%, so the parameters are already well-documented in the input schema. The description adds minimal semantic value—it reiterates that the commit uses staged changes but does not explain parameter interactions (e.g., how all_changes affects staging). This meets the baseline for full schema coverage.

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 commit with the staged changes' clearly states the action (create a commit) and the resource (staged changes), making the tool's purpose unmistakable. It also distinguishes this tool from sibling git tools like git_add or git_push, which handle different operations.

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 usage is implied: you would use this tool when you have staged changes and want to record them as a commit. However, there is no explicit guidance about when not to use it or how it relates to sibling tools like git_add (for staging) or git_push (for uploading), so the guidance is only moderately clear.

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