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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so safety is covered. The description adds the meaningful behavioral qualifier 'uncommitted', which tells the agent what subset of files is returned, but it says nothing about ordering, diff inclusion, or whether staged/unstaged/untracked are all included.

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?

One short sentence with the key qualifier ('uncommitted') front-loaded and no filler. Nothing is wasted or buried.

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 rich annotations, full schema coverage, one required parameter, and an output schema defining the return shape, the definition is nearly sufficient. A brief note on which change states are included and on failure modes for unknown projects would make it complete.

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 single project_id parameter is fully documented in the schema (UUID of a project owned by the authenticated user), so the schema carries the burden. The description adds no extra meaning such as what happens for a nonexistent or unauthorized project, so the high-coverage baseline of 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?

The description names a specific verb ('List') and resource ('uncommitted file changes for a project'), which separates it from projects_files_list since it scopes to uncommitted state. It does not, however, explicitly name its nearest siblings (projects_changes_commit / projects_changes_discard) to sharpen the boundary.

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?

There is no guidance on when to use this versus alternatives such as projects_files_list or the commit/discard siblings, and no stated prerequisites. An agent must infer the workflow context entirely from the tool name.

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