apply_saved_vibe

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It says the tool 'restores' the light configuration, implying it changes current state, but it does not disclose whether it overwrites all light settings, whether it requires authentication, what happens if the name is invalid, or whether effects are temporary.

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 two short sentences with no filler. It front-loads the core action and immediately clarifies the purpose, making it easy for an agent to parse quickly.

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 with one string parameter, so the description covers the basic action. However, without annotations or an output schema, it would benefit from stating side effects (e.g., current lights will be overwritten) and any requirement that the vibe must already be saved.

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 coverage is 100%, so the baseline is 3. The description adds minimal extra meaning by saying 'by name,' which reinforces the name parameter's role, but it does not enrich the parameter semantics beyond what the schema already states.

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 ('Apply') and a specific resource ('previously saved vibe'), and states that it restores the saved light configuration. This clearly distinguishes it from save_vibe, list_saved_vibes, and delete_saved_vibe without needing to inspect the schema.

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 when to use it—when a saved vibe should be applied—but gives no explicit guidance on when not to use it or which sibling to use instead. It does not mention preconditions such as the vibe needing to exist, nor does it distinguish usage from set_vibe or set_scene.

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