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

Annotations already declare readOnly/idempotent/non-destructive, and the description stays consistent while adding genuinely new context: an auth requirement (X-RapidAPI-Key or X-SignalTender-Key), statelessness, and the regulatory grounding (FAR 16.505(b)(1), $10M/$25M protest caps, GSAR 552.216-74). It does not discuss cost, rate limits, or failure modes, which keeps it below a 5.

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?

It is front-loaded with the action, but it is a single run-on block that packs the response field list, legal citations, auth requirements, and parameter notes into one paragraph. The usage sentence repeats the tool name verbatim, and the enumerated response fields duplicate the output schema, so several clauses do not earn their place.

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?

With an output schema present, the return-value enumeration is redundant but harmless; the description still supplies the auth, statelessness, and scoping context an agent needs before calling. Nothing critical is missing for a three-parameter read-only analysis tool.

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 100%, so the baseline is 3. The description does explain the role of the two optional knobs ('calibrate the regulatory regime and threshold assumptions') and repeats the 15–45,000 character bound, but adds no syntax, format, or accepted-value guidance beyond what the schema already states.

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 concrete verb ('Match') against a specific resource set — task order TORFPs across OASIS+, Polaris, 8(a) STARS III, VETS 2, SEWP, CIO-SP3/4 — plus scorecard scoring and rapid TORFP drafting. The final sentence explicitly separates it from scan_far_dfars_clauses and generate_compliance_matrix, so an agent can route correctly without opening a schema.

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?

Names two alternative siblings and the condition that selects each ('general FAR/DFARS clause flow-down audits', 'general Section L/M shall requirement extraction'), which is real routing guidance. The positive trigger ('use this tool when executing GWAC / IDIQ Task Order Fair Opportunity... workflows') largely restates the tool name, so the when-to-use side is weaker than the when-not side.

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