wired_article

Read-only

One WIRED article's public metadata and full body paragraphs from a canonical article URL. Subscriber-only stories return a permission error instead of a truncated or fabricated body.

TDQS

A4/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds genuinely useful behavioral detail beyond that: subscriber-only stories fail with a permission error rather than returning a truncated or fabricated body, which tells the agent how to interpret an error response.

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?

Two tight sentences with the payload description front-loaded and the failure-mode caveat second, with no redundant or filler text.

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?

Output schema exists, so return shape need not be explained, and the description covers the one non-obvious behavior (subscriber-gated permission errors). Slightly short of 5 since nothing addresses malformed/non-canonical URLs, but it is complete enough for correct invocation.

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 only one parameter exists, so the schema fully documents the url argument. The description's phrase 'canonical article URL' restates the schema rather than adding format or validation detail, so baseline 3 is appropriate.

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?

The description names a specific resource (one WIRED article's public metadata plus full body paragraphs) and the input it draws from (a canonical article URL). An agent can distinguish it immediately from wired_headlines, wired_news, and wired_sections, which are list/aggregate tools, 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.

Usage Guidelines3/5

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

Usage is only implied: it takes a canonical article URL, so the agent infers it should be called once a URL is in hand. There is no explicit when-to-use statement or pointer to a sibling (e.g. wired_headlines) for discovering URLs first.

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