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

Annotations already cover read-only, idempotent, non-destructive, open-world behavior, and the description adds real value beyond them: it decodes the four status semantics and warns that fully_ready is legacy-compatible and not a comprehensiveness claim. It does not mention auth needs or rate limits, but for this read-only inspection tool that gap is minor.

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?

Front-loaded with the action and the pre-use context, then the enum semantics. Every sentence carries meaning, though the chained status definitions are dense and could be slightly more scannable.

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?

An output schema exists, so return shape need not be described, and the description supplies the one thing an agent genuinely needs that structure cannot convey: what each readiness status actually means. Adequate for a single-parameter read tool, with only sibling differentiation left implicit.

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?

There is a single pack_id parameter with 100% schema description coverage, so the schema fully documents the input and the description adds nothing parameter-specific. This is the baseline 3 case where structured data does the lifting.

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 ("Inspect") and resource (readiness, source coverage, freshness of a Vera pack), and the enum definitions make it distinguishable from get_pack_build_status and get_verification_status. It does not explicitly name those siblings, so it stops short of a 5.

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?

Gives a clear trigger context ("before high-stakes use") plus an actionable directive to disclose incomplete or stale coverage. It never names a when-not condition or an alternative sibling tool, so it falls short of the explicit routing a 5 requires.

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