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

Annotations already declare this a read-only, idempotent, non-destructive, closed-world call, so the safety profile is covered. The description does add one meaningful behavioral trait beyond them: "account-safe" implies the payload is sanitized of sensitive values, which matters for an agent reasoning about what it can safely surface. It adds nothing about freshness, caching, or what the context contains.

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?

A single tight sentence with no filler; the purpose is front-loaded. It is arguably too terse for the ambiguity it needs to resolve, but there is no wasted wording.

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?

An output schema exists, so return values need not be explained, and the annotations carry the safety profile. The remaining gap is disambiguation: with four setup-related siblings, the description never clarifies what makes this context different from install instructions or setup status, which is the one thing an agent most needs.

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 takes zero parameters, so there is no parameter semantics to document and nothing for the description to compensate for. This is the baseline-correct case.

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 verb (Return) and a resource (setup context), so the action is identifiable. But "account-safe setup context" is vague about what is actually returned, and the description does nothing to separate it from sibling tools like get_install_instructions or read_setup_status, which sound like they cover the same ground.

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 phrase "for an AI assistant helping install AffiliateBase" gives a loose scenario but never states when to call this tool versus get_install_instructions, read_setup_status, or verify_tracking_installation. No prerequisites, ordering, or exclusions are offered.

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