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

No annotations are provided, so the description must carry the full behavioral burden. It discloses that the tool can flag and prune dead labels, and that dry_run plans, but it does not explain what '1 read + sidecar' means, whether writes are reversible, what sidecar modifications involve, or what the output looks like. This is a meaningful gap for a tool with destructive potential.

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 very short and front-loaded, with each sentence adding a distinct piece of information: what is reconciled, what can happen, and the planning mode. The cryptic phrase '1 read + sidecar' slightly reduces clarity, but overall the text is efficient and free of fluff.

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?

Without annotations or an output schema, the description needs to explain the sidecar concept, the exact return format, the effects of prune, and the meaning of '1 read + sidecar.' The current description leaves too many practical details undefined for an agent to confidently invoke the tool in varied situations.

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 100%, so the schema already documents all three parameters, their defaults, and enums. The description adds no parameter-specific meaning beyond what the schema states, except implicitly tying prune to the flagged dead labels and dry_run to planning, so the baseline score of 3 applies.

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?

States a specific verb, 'reconcile', with clear resources: sidecar device labels/volume presets and scene device hints against the live device list. The outcome, flagging and optionally pruning dead labels, is also specified. However, the term 'sidecar' is domain jargon and '1 read + sidecar' is cryptic, so it is not perfectly clear to an unfamiliar agent.

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 explicit guidance on when to use this tool versus alternatives such as list_device_presets, apply_device_presets, compare_devices, or get_devices. The mention of dry_run suggests a planning workflow, but the description does not state when this tool is preferred or when it should not be used.

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