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

With no annotations, the description carries the burden and does disclose real behavior: every implementation specification is mapped to receipt-derived evidence, missing REQUIRED specs become surfaced findings rather than silent gaps, and ADDRESSABLE specs accept an operator note. It stops short of saying whether an artifact is written to disk, what permissions are needed, or what the returned binder looks like.

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?

Three dense sentences, front-loaded with the artifact and regulation, then behavior, then edge-case handling. No restatement of the tool name and no filler.

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 no output schema and a nested scope object, the description covers the main thing an agent needs to know: the output is a spec-to-evidence binder with findings for unevidenced REQUIRED controls. The one real gap is the return shape of that binder, which the description gestures at but never characterizes.

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 100%, so baseline is 3; the description adds value by tying 'receipts' to receipt-derived evidence and by explaining the semantics of the optional implementationStatus map (ADDRESSABLE specs can be marked alternative-implemented, which is the only status branch with special meaning). It doesn't explain the required HipaaScope subfields.

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 and artifact: 'Build a HIPAA Security Rule (45 CFR § 164.308-318) evidence binder' from VAOS receipts. The named regulation and control family make it unambiguously distinct from siblings like build_gdpr_dpia or build_soc2_evidence without opening any 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?

The input context is clear ('from a set of VAOS receipts'), which implies when the tool applies, but there is no explicit when-to-use / when-not-to-use guidance and no routing statement toward the sibling framework builders. An agent must infer that HIPAA scope selects this over build_iso_42001 or build_gdpr_dpia.

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