tmux_rename_window

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

Annotations are absent, so the description carries the full burden of behavioral disclosure. It only says 'Rename', which implies a mutation, but nothing about effects on other windows/sessions, error behavior if the target is invalid, whether the new name must be unique, or if the operation is reversible. No additional context is provided beyond the basic action.

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 extremely concise: a one-sentence purpose statement and a two-line argument explanation. It is front-loaded with the action, every sentence contributes, and there is no fluff. The format is clean and easily parseable by an agent.

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 simple two-parameter rename tool with an output schema present, the description is reasonably complete on purpose and parameters, but lacks usage guidelines and behavioral context. Since there are no annotations, the agent is left guessing about prerequisites and side effects. It is minimally viable but not fully self-sufficient.

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 schema offers no descriptions (0% coverage), but the Args section compensates by explaining 'target' as a 'Tmux target for the window (e.g. "session:window")', which adds a concrete format example. 'new_name' is described as 'New name for the window' which is essentially the title but still confirms intent. This adds meaningful value over the bare schema, though more detail on target syntax variations (e.g., just window name) would be helpful.

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 'Rename a tmux window' with a specific verb and resource. It distinguishes from sibling tools like tmux_rename_session by specifying 'window', and the name itself aligns perfectly. No redundancy or ambiguity.

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 guidance on when to use this tool versus alternatives such as tmux_rename_session or tmux_create_window. No context is provided about prerequisites (e.g., the window must already exist) or when renaming is appropriate. The description simply states what the tool does without any exclusions or situational guidance.

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