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

Adds real context beyond the annotations: no quota consumption, pointer semantics, informational-only framing, and an explicit disclaimer that results are not a prediction of future awards. The annotations already cover read-only/idempotent/non-destructive, so this extra economic and interpretive context is genuinely additive. The gap is that it never says what a 'pointer' response looks like, despite there being no output schema.

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 actual purpose sentence appears third, buried behind three compliance disclaimers. The disclaimers likely earn their place legally, but they push the operationally useful content back and force the agent to read past boilerplate to find scope.

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-required-param, no-output-schema tool that self-describes as a router, the description leaves the most important question open: what does it return, and how should the agent act on a pointer? Interpretation guidance is partly covered ("present as information only"), but the core mechanics of the pointer behavior are not.

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 coverage is 67%; naics and agency carry descriptions, limit does not (though min/max self-document it). The description contributes nothing about the parameters — not whether multiple NAICS codes are compared side by side, whether agency is fuzzy-matched, or how limit bounds the analysis. With a tool this opinionated about interpretation, that silence matters.

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 names a domain ("award history, subawards, OTA awards, and agency spending patterns. Shows who won what, for how much"), which is more than a restatement of the name. But the closing "This is a pointer tool... it directs you to the tool that does the work" undercuts that, making it unclear whether analyze_market computes an answer or just routes. Siblings search_award_history, search_subawards, and search_ota_awards cover the same territory and no differentiation is offered.

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?

Explicit negative routing is present and strong: "NOT for bid/no-bid, pursue-or-pass, eligibility, qualification... for those call explain_policy_boundary first and do not research or use memory to answer" names the exact alternative tool. What's missing is positive routing — given it claims to be a pointer, it doesn't say which downstream tool it points to or when to skip it and call search_award_history directly.

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