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

Annotations already flag destructiveHint=true and idempotentHint=true; the description adds the crucial qualifier that nothing is actually destroyed until commit, which materially changes how an agent should reason about the risk. It stops short of explaining how to revert the staged change.

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 short sentences, zero filler, with the deferred-effect warning front-loaded right after the action. Nothing is redundant with the title.

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?

With an output schema, full annotation coverage, and fully documented parameters, the description only needs to explain the staged-mutation semantics, which it does. A brief note on how to undo or what happens to a nonexistent path would close the remaining gap.

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%, with both project_id and path documented inline, so the description carries no parameter burden. It adds no syntax or format detail beyond the schema; baseline 3 applies.

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?

States a specific verb (stage deletion) and resource (a file) and immediately makes the staging/commit distinction that separates it from projects_changes_commit and projects_files_update.

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 'stays uncommitted until projects_changes_commit' clause tells the agent this is step one of a two-step workflow and names the sibling that finalizes it. It does not mention that projects_changes_discard is how you back out, so the reverse path is left implicit.

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