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

With no annotations, the description must carry the behavioral disclosure burden. 'List' implies a read-only operation, but the description does not state permissions, output behavior, default limits, mode selection semantics, or whether the operation has any side effects. The rich schema hints at complex behavior that the description does not surface.

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 single-sentence description is concise and front-loads the core action and object. However, given the tool's complexity, some additional structured detail about modes would be earned without sacrificing conciseness.

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?

The tool has 14 parameters, four mutually exclusive usage modes via anyOf, no output schema, and no annotations, yet the description is only one short sentence. It does not explain which mode to choose, what the output contains, or how this relates to sibling tools, so an agent will likely struggle to invoke it correctly.

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 schema already documents all 14 parameters. The description adds minimal extra meaning beyond 'between two paths', which aligns with sourcePath and targetPath but does not explain the branch, stream, reverse, or useBranchSource modes.

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 ('List'), a clear resource ('changelists'), and a distinctive condition ('not yet integrated between two paths'). This is a clear, non-tautological purpose, but it does not explicitly differentiate itself from closely related sibling tools such as p4_integrated or p4_changes.

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 tool versus alternatives, no mention of branch/stream modes, and no exclusions. The intended usage is only implied by the tool name and one-line description, leaving the agent to infer when this is the right choice.

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