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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuinely new context: auth requirement (X-RapidAPI-Key / X-SignalTender-Key), statelessness, and the 15–45,000 character input bound. It restates 'read-only, stateless, non-destructive' somewhat redundantly, keeping it from 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?

Purpose and routing are front-loaded, but the prose is a dense run-on that repeats the full FAR/DFARS citations three times, re-lists the tool title, and restates schema character limits. Several clauses could be trimmed without losing information.

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, return values need not be explained, yet the description enumerates response keys anyway (mild redundancy). It otherwise gives auth, input bounds, and regulatory grounding sufficient for correct invocation of a single-required-parameter 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 only repeats the character range (15 to 45,000) already in the schema and gestures at what `dcma_property_system_audit_scope` and `liability_and_cap_regime` calibrate, without adding format or option guidance beyond the defaults.

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 (Audit) and resource (GFP/GFE/GFI attachments under FAR 52.245-1 / DFARS 252.245-7003/7005) and names the concrete deliverables (PMSP, PIEE GFP Module workflow, IUID checklist). An agent can distinguish this from sibling clause-scanning and matrix tools without opening the 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?

Explicitly routes the caller: use this for GFP/FAR 52.245-1 and PIEE Property Management Plan workflows, and use `scan_far_dfars_clauses` for general FAR/DFARS flow-down or `generate_compliance_matrix` for Section L/M 'shall' extraction. That is when-to-use plus named alternatives with selection conditions.

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