modify_changelists

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

With no annotations, the description bears full burden. It mentions 'WRITE permission' and lists actions, but does not explain side effects (e.g., deletion consequences, submission requirements) or dependencies beyond what the schema provides.

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 one sentence, concise and front-loaded with the main purpose. It could be slightly more structured (e.g., bullet list of actions), but it is efficient with no wasted words.

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?

Given the tool's complexity (4 parameters, multiple action enums, output schema exists), the description covers the high-level purpose but lacks details on conditional parameter requirements and workflow steps. Still, it is largely sufficient for an agent with schema access.

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 baseline is 3. The description adds minimal value beyond the schema; it repeats action types but does not clarify parameter interactions or conditional requirements (e.g., file_paths needed for move_files).

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 tool's actions (create, delete, update, organize) on changelists, with 'WRITE permission' indicating the kind of operations. It distinguishes from sibling tools like query_changelists and other modify tools.

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 explicit guidance on when to use this tool vs. alternatives. The description implies it is for changelist modifications, but does not mention when not to use it or suggest alternatives like query_changelists for reading.

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