A4/5.0

Behavior3/5

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 fully covered by structured data. The description's additional value is the pre-flight framing (cheap inspection ahead of get_data) and a summary of returned content. It does not add anything about unknown-ID behavior or lookup cost, so it is solid but not rich.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence that front-loads the verb and resource and ends with the routing cue. Every clause carries information; nothing is padded or redundant.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, the description need not enumerate return fields, and annotations plus a 100%-covered single parameter handle the rest. The only thin spot is behavior when an unknown or stale pack ID is passed, which the description never touches.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the single pack_id parameter is well documented in the schema itself (origin in get_catalog, note about newly admitted packs). The description only adds the emphasis that the ID must be exact, which is marginal but consistent with the baseline for fully covered schemas.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (inspect), a specific resource (one exact data pack ID), and what the inspection yields (metrics, time coverage, query metadata). This cleanly separates it from get_catalog (enumeration) and get_data (retrieval) without the agent needing to open any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'before get_data' gives an explicit sequencing rule for when this tool belongs in a workflow, and the schema's 'from get_catalog' note completes the chain. There are no stated exclusions or failure conditions, so it falls just short of a full when/when-not statement.

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