rename_list

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

No annotations are provided, so the description carries the full behavioral burden. It does disclose one genuine constraint beyond the schema — that list names must be unique — but says nothing about what happens on a duplicate (error vs. overwrite), whether a rename is reversible, or permission requirements.

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, front-loaded with the action, with no filler. Slightly terse for a mutation tool whose uniqueness rule could use scoping detail, but nothing is wasted.

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?

For a low-complexity two-parameter mutation with no output schema, the description covers the core action and the uniqueness constraint. However, with zero annotation and schema coverage it should at least state the failure mode on duplicate names or the required permissions.

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 0%, and the schema titles ('List', 'New Name') carry no meaning. The description partially compensates by explaining that the 'list' parameter accepts a name or an id, but adds nothing about 'new_name' beyond the obvious.

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 gives a specific verb+resource ('Rename a list') and clarifies the identifier form ('name or id'). It is clearly distinguishable from the sibling rename_calendar by resource, though it does not explicitly note that distinction.

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 when-to-use guidance, prerequisites, or alternatives are given, even though rename_calendar is a close sibling that an agent could confuse with this tool. The agent must infer the context entirely.

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