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

Annotations already declare readOnly, idempotent, non-destructive, closed-world behavior, so the safety floor is covered. The description adds genuinely new context beyond them: it enumerates what the response contains and explicitly states 'This tool cannot move funds,' which matters because sibling tools prepare and settle checkouts.

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?

Three short sentences, front-loaded with the triggering condition and the ordering cue, then the payload contents, then the safety boundary. No filler or restatement of the title.

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?

With no output schema, the description carries the return-value burden and does so by listing the contents (scope, price, schemas, examples, limitations, payment boundary, links). For a zero-parameter read-only info tool, nothing an agent needs before calling it is missing.

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 tool takes zero parameters, so the baseline is 4 and there is no schema-level parameter meaning the description would need to compensate for.

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 action (return the service's scope, price, schemas, examples, limitations, payment boundary, integration links) for a specific resource (the Preflight QA Lab service). The intro clause 'Use this first when an agent needs pre-release AI output verification' orients it against the sibling quote/checkout/report tools, though it never names them explicitly.

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?

'Use this first' gives explicit ordering guidance relative to the other venture_foundry tools, and the condition (agent needs pre-release AI output verification) is stated. It stops short of naming which sibling to use instead once the info is consumed, so it is clear context without exclusions.

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