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

Annotations already mark this as read-only and non-open-world, and the description adds that the tool returns a randomly selected labeled strategy card. This is sufficient for a side-effect-free creative tool; no contradiction with annotations.

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 guidance is mostly well organized, but there is redundancy: 'breaking self-imposed limitations' and 'break through blocks' convey the same idea, and 'Use when' plus 'Use this when' split related guidance unnecessarily. It could be tightened without losing meaning.

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 zero-parameter, read-only random generator with no output schema, the description covers what it does, when to use it, and what it returns. It could be slightly clearer about the exact shape of the 'strategy card', but nothing critical is missing for correct invocation.

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 tool has zero parameters and full schema coverage, so the description does not need parameter details. The baseline for a no-parameter tool is 4, and nothing is missing here.

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 opens with 'Get a random Expand strategy', a specific verb and resource, and the category name 'Expand' distinguishes it from the sibling category tools. The title 'Sideways: Expand' reinforces the resource without 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?

Provides explicit triggers ('when solutions feel too minimal, when avoiding decisions') and concrete use-case keywords ('add more, elaborate, embrace abundance, do both'). It does not explicitly contrast with the siblings, but the category names and context make the selection clear enough.

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