  2. First observed

TDQS

A3.7/5.0
Behavior4/5

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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive), so the description's job is to add context, and it does: it discloses ordering (publication order), inclusion scope (public contributions only), and a genuine data-quality caveat that guest contributions are unverified opinions, not facts. That caveat is nowhere in the annotations or schema and is exactly the sort of signal a calling agent needs.

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

Conciseness4/5

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

Two compact sentences with no filler; the content enumeration comes first and the guest-contribution caveat closes. The only weakness is that it opens as a noun phrase rather than leading with the action, so the key 'this fetches one question' fact is implicit.

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 needn't document return shape, and it still usefully characterizes what the payload contains plus a caveat about guest content. For a single-parameter read tool with full annotations, the only missing piece is guidance on when to prefer it over the search/browse siblings.

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 coverage is 100% and the single parameter already documents that it accepts a UUID, slug, or canonical/API URL. The description adds nothing about identifier formats, so it neither helps nor hurts beyond the baseline.

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

Purpose4/5

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

The description specifies the resource (a published question) and enumerates exactly what comes back: every public contribution in publication order, evidence links, and links to consolidated knowledge records. That is enough to distinguish it from get_knowledge or browse_knowledge, though it never states the verb ('retrieves a single question') explicitly.

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: the tool fetches one published question by identifier, which an agent can infer from the single id_or_url parameter and the 'published' qualifier. No sibling is named (search_knowledge, browse_knowledge, get_knowledge) and no condition for choosing this over them is given.

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