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 the valuable detail that the result includes provenance and permission data alongside the canonical artifact. It says nothing about failure modes (unresolvable URI, missing artifact) or authentication/rate limits against w3bs.org.

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?

Two short sentences, with the substantive content front-loaded in the first. The second sentence is attribution boilerplate that adds little for tool selection but costs almost nothing.

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?

A one-parameter, read-only tool with strong annotations and no output schema, so the description needn't explain return values. Still, it leaves the key unknown — what the `uri` looks like and what "the canonical artifact" actually contains — which matters because there is no output schema to fall back on.

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?

The single parameter `uri` has 0% schema description coverage and the description never mentions it. An agent gets no hint of accepted URI scheme (e.g. w3bs:// or https), whether it identifies an artifact or a package, or what a malformed value does. The word "artifact" only loosely implies the parameter's target.

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 enumerates the concrete facets returned: identity, provenance, permissions and the canonical artifact. That is far more informative than the bare name, but it never distinguishes this from plausible siblings such as w3bs_resolve, w3bs_verify or w3bs_conformance.

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?

There is no when-to-use guidance, no prerequisites, and no mention of any alternative tool. The only signal is the word "Inspect," which weakly implies a read/lookup operation; an agent must guess whether to reach for this or for resolve/verify.

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