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

With no annotations provided, the description carries the full burden of behavioral disclosure. It discloses atomic writes, re-reading of the file, and returns of doc_hash plus warnings about unmodeled features. This is valuable detail. It does not mention reversibility or concurrency checks, but the atomic write and re-read give a solid sense of safe 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?

Two sentences, highly efficient. The main purpose is front-loaded, followed by key behavioral notes. No fluff or redundant phrasing. Every sentence contributes.

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?

An output schema exists, so return values are covered separately. The description explains the core behavior and output (doc_hash, warnings), but omits details like the significance of doc_hash as a parameter, potential errors, or behavior when no changes are staged. Given the moderate complexity (3 params, 1 required), it is adequate but has clear gaps.

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 explain parameters. It implicitly explains change_ids ('selected change ids') but does not clarify the role of doc_hash (likely an optimistic concurrency token) or path (though path is self-evident). The description adds minimal value beyond the schema for parameters, leaving doc_hash underspecified.

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 clearly states the action: 'Commit staged changes to the file' with an option for all or selected change ids. It implies the file is specified by path (required param). It is distinct from the sibling 'discard_changes' which does the opposite, though it doesn't explicitly name the alternative. Purpose is clear and specific.

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 implies the tool is for finalizing changes that have been staged (presumably via get_changes or propose_* tools) but does not explicitly state when to use it versus alternatives like discard_changes. There is no mention of prerequisites or a typical workflow. Usage context is inferable from siblings but not spelled out.

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