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

No annotations are provided, so the description carries the full disclosure burden, and it discloses nothing. It does not say whether the tool is read-only or mutating, whether it emits a plan document, what inputs it requires, or whether any side effects occur.

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?

It is short, but brevity here reflects under-specification rather than efficient communication. The single fragment carries no actionable content for the 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?

A 2-parameter tool with no annotations, no output schema, and 0% schema description coverage needs the description to do substantial work, and this one does none. Nothing an agent needs to invoke the tool correctly is present.

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?

Both parameters (targetSdk, environment) have enums that self-document their allowed values, but schema description coverage is 0%, and the description adds no meaning about how the two interact or what happens when they are omitted (0 required parameters). The names are somewhat self-explanatory, which keeps this above a 1.

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 merely restates the tool name and its alias ('mediasfu-shared :: embedded.layout.plan (embedded-layout-planner)'). There is no verb and no statement of what 'planning an embedded layout' produces or entails, so an agent cannot distinguish it from siblings like shared::frontend.architecture.plan or shared::widget.integration.plan.

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 when-to-use guidance, no prerequisites, and no mention of any alternative tool. The agent is given no basis for choosing this over the many other shared::*.plan tools in the sibling list.

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