rename_track

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

With no annotations, the description carries the full behavioral burden and fails it. It does not state whether renaming overwrites an existing name (destructive), whether the track must already exist, what happens on an out-of-range index, or what the call returns. Only the bare mutation intent is conveyed.

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?

Four words, front-loaded, zero waste — but the brevity is under-specification rather than effective conciseness. It is appropriately short for a trivial operation but leaves critical detail unstated.

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 mutation tool with no annotations, no output schema, and 0% parameter documentation, the definition is not complete enough for reliable invocation. The agent cannot determine indexing convention, error behavior, or the result of the operation.

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 both parameters are opaque: "index" never specifies 0-based vs 1-based track addressing, and "name" is only weakly implied to be the new track name. With two required params and no schema documentation, the description should have compensated but adds nothing.

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 clear verb and resource ("Rename a track"), so an agent knows the general operation. However, it is essentially a restatement of the tool name and adds no distinguishing detail versus siblings like batch_rename_items or batch_rename_regions (which target different resources) or versus the set_track_* family. Minimum viable, no differentiation.

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 when-to-use guidance, no prerequisites, and no mention of alternatives such as batch_rename_items for renaming multiple items. The agent must infer usage entirely from the name.

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