approve_file_changes

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

Beyond the destructive annotation, the description explains exactly what is destroyed: the backup is discarded, the journal entry is cleared, and modifications remain permanently on disk. This gives an agent the side-effect information needed before invoking a destructive 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 well structured and front-loaded with what it does, when to use it, and side effects. It contains some repetition, such as restating that the journal entry is removed and including a return line despite the output schema.

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 a single-parameter destructive tool, the description covers purpose, prerequisites, alternatives, side effects, parameter format, and return behavior. An agent has enough context to decide when to call it and what the consequences will be.

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 schema has 0% parameter description coverage, but the description compensates by specifying that file_path is relative to the project root and provides concrete examples. This adds meaningful syntax guidance beyond the bare string parameter.

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 states a specific verb and resource: it approves pending changes for a specific file. It also distinguishes this from approve_all_files, making the scope clear without needing the schema.

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 gives a clear prerequisite: inspect via get_file_diff and verify correctness before approving. It also names approve_all_files as the alternative for approving all files, but the exclusion 'File must be modified' is ambiguously worded.

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