Pre Commit

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=false. The description adds a useful constraint not covered by annotations: it only supports typed Git operations and prohibits arbitrary host commands. However, it still omits mutation effects, permissions, and reversibility details for an 11-parameter tool.

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 short and front-loaded, but the first fragment merely repeats the title/name and the middle sentence is overly generic. The final constraint is the only sentence that clearly earns its place, leaving the overall structure underpowered for the tool's complexity.

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?

For an 11-parameter tool with many Git-related siblings and actions referenced in the parameter schema, the description is drastically incomplete. It does not explain the action model, primary use cases, or how this tool relates to alternatives, even though an output schema exists and annotations cover safety hints.

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 100%, so the parameter-level descriptions already carry the syntax and default details. The tool description adds no additional parameter meaning, but the baseline is 3 when the schema documents all parameters thoroughly.

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 largely restates the tool name/title ('Pre commit (rm_git)') and then gives only a vague category ('Typed bulk Git operations'). It does not state what the pre-commit operation actually does or distinguish it from siblings such as rm_git_commit, rm_git_commit_code, or repository_manager_pre_commit.

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 no when-to-use guidance, no alternatives, and no preconditions for calling the tool. The prohibition on arbitrary host commands is a boundary, but it does not tell an agent when this tool should be selected over other Git-related siblings.

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