TDQS

A3.8/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered structurally. The description adds little behavioral context beyond noting the output is 'for citation' – no rate limits, id-expiry, or failure behavior. With annotations carrying the load, a 3 is appropriate.

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 tight sentences, front-loaded with the tool's identity and the id-provenance constraint, with no filler. Slightly dense with the 'OpenAI ChatGPT Deep Research / Connectors fetch contract' preamble but overall efficient.

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?

An output schema exists, so return-value documentation is not needed, and annotations cover safety. For a single-parameter fetch tool the description covers purpose, provenance, and id format adequately; only edge-case behavior is absent.

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

Parameters4/5

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

Schema description coverage is 0%, so the description must compensate, and it does by spelling out the required id format with three concrete variants ('artist:<uuid>', 'campaign:<uuid>', 'smartlink:<uuid>'). That is genuinely useful meaning beyond the bare `string` type, though it doesn't address length limits.

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?

States a specific verb/resource: given an id it 'returns the full record for citation.' It also names the companion tool (`search`) that produces the id, so an agent can place it relative to siblings rather than guessing.

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?

Clearly establishes the dependency: it must be called with an id 'returned by `search`,' which is an explicit usage context and ordering constraint. It stops short of stating when NOT to use it (e.g., when you only need list results, use search), so it's not a full 5.

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