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

With readOnlyHint/destructiveHint/openWorldHint annotations already covering safety, the description adds genuinely new behavioral context: results are derived from 'live public availability, not a hard-coded price table', and the bare-metal input silently changes the return type into a quote handoff. That return-type switch is important disclosure, though the overall response shape remains unspecified since no output schema exists.

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?

Two dense sentences with the core capability front-loaded and the dedicated branch immediately after; little waste. Slightly jargon-heavy phrasing ('workload-specific Dedicated quote handoff') costs a bit of immediate readability.

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 6-param, all-optional, read-only recommender with no output schema, the description supplies the essential pieces: what is recommended, the data source, and the dedicated-input branch. Remaining gaps are per-parameter details rather than missing behavior.

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 0%, so the description must carry parameter meaning; it partially does by mapping 'for a goal' to workload, 'bare metal explicitly requested' to the dedicated value, and naming 'optional backup/object-storage components' for needsBackup/needsObjectStorage. needsRoot, needsDomain, and expectedTraffic get no explanation at all, leaving half the parameters opaque.

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 ('recommend') and a precisely scoped resource ('smallest currently orderable public product set for a goal'), plus the alternate branch that returns a Dedicated quote handoff. An agent can distinguish it from list_public_products or quote_public_product by the recommendation/branching behavior, though no sibling is named explicitly.

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 description implies usage ('for a goal', and the dedicated branch 'when bare metal is explicitly requested'), which does route one scenario correctly. But it never states exclusions or names the alternative siblings (quote_public_product, list_public_products) for raw pricing or catalog browsing, so the agent must infer when not to call this.

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