p4_changelist_update

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

With no annotations, the description must disclose behavioral traits on its own. It only says 'Update', revealing that the tool mutates state, but does not explain side effects, required preconditions, reversible nature, or what happens to the changelist's files and description.

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 a single concise sentence with no wasted words, and the core purpose is front-loaded. However, it is so terse that it misses oportunities to add routing or behavioral context, but as a concise statement it works.

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?

There is no output schema and no annotations, so the description is the only source of context. A simple 'Update an existing changelist' does not explain return values, side effects, prerequisites like a pending changelist, or how workspacePath factors in, leaving an agent under-informed.

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 all parameters already explained in the input schema. The description adds no additional meaning about parameters, so baseline of 3 is appropriate since the schema carries the burden.

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 a specific action ('Update') and resource ('existing changelist'), which distinguishes it from create or submit siblings. However, it does not explicitly name or differentiate from sibling tools like p4_changelist_create.

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?

No guidance is given on when to use this tool vs alternatives such as p4_changelist_create or p4_changelist_submit. The description only implies usage through the verb 'update', which does not help an agent decide between sibling tools.

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