timeline_set_name

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

With no annotations provided, the description carries the full burden of behavioral disclosure, but it only states the action without mentioning side effects, error conditions, or return behavior. It does not contradict annotations (there are none), but it offers very little beyond the basic operation.

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, front-loaded sentence with no filler or redundancy. Every word earns its place, and it is appropriately minimal for a simple setter tool.

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 is simple: one required parameter, an output schema likely present, and a clear operation. The description, while sparse, is sufficient for the agent to understand the core action and parameter. It lacks only minor usage nuance (e.g., what 'current timeline' implies) but is otherwise complete for its complexity.

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 input schema already fully describes the single required parameter (name) with 100% coverage, so the description adds no extra semantic value beyond restating 'new name'. Baseline 3 applies given the high schema coverage.

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 uses a specific verb ('Rename') with a clear resource ('the current timeline'), and this unambiguously distinguishes it from sibling tools like timeline_get_name (read) and timeline_set_current (changing the active timeline).

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?

The description implies usage for renaming the current timeline but provides no guidance on preconditions, when to choose this over other rename/set tools, or any exclusions. It does not mention alternatives like timeline_set_track_name, leaving the agent to infer from the name alone.

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