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, and it discloses nothing. It does not say whether the tool is read-only or mutating, whether the 'plan' output is generated versus persisted, what permissions or preconditions apply, or what the result looks like. This is a bare identifier, not a description.

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 the brevity stems from under-specification rather than efficient communication. There is no front-loaded statement of purpose and no substance to trim; the sentence adds nothing beyond the name already exposed in structured metadata.

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 tool taking one enum parameter and returning a plan, with no annotations and no output schema, the description should explain the pattern taxonomy and intended use. Instead it says nothing, leaving the agent without the information needed to invoke it correctly.

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?

There is a single 'pattern' parameter with an enum (familiar, auction, watch, agents, voip, spacestek) at 0% schema description coverage. The enum literals convey a little inherent meaning, but the description never explains what a 'pattern' selects or how it changes the plan output, so semantics are effectively undocumented.

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 is a pure restatement of the tool name and title: 'product.pattern.plan (product-pattern-planner).' It contains no verb or statement of what the tool actually does, and offers no basis for distinguishing it from the many sibling '*plan' tools (room.lifecycle.plan, frontend.architecture.plan, participant-control.integration.plan, etc.). An agent cannot determine the tool's purpose from this text.

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, when not to, or which sibling it replaces or complements. Given dozens of similar planning siblings, the absence of any routing signal is a critical gap, not a minor one.

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