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

Annotations already declare readOnlyHint, destructiveHint false, idempotentHint, and openWorldHint false, so the safety profile is covered. The description adds useful context beyond annotations: it specifies statelessness, requires an X-RapidAPI-Key, and defines input length boundaries. It stops short of detailing rate limits, error behavior, or output retrieval mechanics, but the additions are meaningful.

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 description is front-loaded with core purpose and deliverables, then transitions to usage guidance and behavioral details. Every sentence contributes value, though the first sentence is dense and slightly overlong. The repeated safety modifiers (read-only, stateless, non-destructive) mirror annotations but are not entirely redundant because statelessness is not explicitly annotated.

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?

Given the complexity and the existence of an output schema, the description covers all critical aspects: what the tool produces, when to use it, authentication requirements, input constraints, and how parameters calibrate output. No essential information for correct invocation is missing.

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 schema already documents all parameters including min/max lengths, defaults, and enums. The description restates the character range and explains how `cpar_submission_mode` and `target_far_42_1503_rating_goal` calibrate self-assessment vs. rebuttal modes, but adds little beyond what the schema provides. Baseline 3 is appropriate.

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 a specific transformation verb and enumerates the exact deliverables: CPARS Self-Assessment Package, factor-by-factor rating upgrade narratives, 14-day RO Rebuttal Brief, and COR Evidence Binder checklist. It explicitly distinguishes itself from sibling tools by naming `generate_cpars_past_performance` and `analyze_debriefing_bid_protest` with their respective use cases.

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?

It provides explicit when-to-use guidance (preparing annual CPARS Self-Assessment or rebutting an unfavorable draft CPAR within the 14-day window) and when-not-to-use guidance with named alternatives for past performance formatting and debriefing/bid protest analysis. The statutory context (FAR 42.1503(d)) further clarifies the timing and purpose.

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