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

Annotations already declare readOnlyHint, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description contributes only the content framing (ROI-first, fixed-fee packages) and says nothing about whether this returns marketing copy, a rate card, or whether pricing is negotiable.

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 front-loaded sentence with no waste. The parenthetical earns its place by scoping the pricing philosophy, though the fragment style makes it read more like a tagline than an instruction.

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 no-parameter, read-only knowledge lookup this is close to sufficient, but with no output schema the description never indicates what form the answer takes (static text, tiers, quote request path). One clause on the return shape or on when pricing must instead go through start_proposal would make it complete.

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?

Zero parameters with 100% schema coverage, so there is nothing for the description to disambiguate. Baseline 4 applies.

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 states the resource precisely: the pricing model of 'The Outcome Layer', characterized as ROI-first fixed-fee packages. That is enough to distinguish it from siblings like get_offer, get_company_facts, or get_proposal, though it phrases the action as a topic rather than a verb.

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 call this versus get_offer or start_proposal, and no prerequisites or exclusions. The agent must infer that this is the pre-sales 'how do you charge' lookup.

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