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

Beyond the annotations (readOnlyHint=false, idempotentHint=true, destructiveHint=false), the description reveals the approval workflow, possible narrowing by the owner, lack of readable data before approval, and absence of returned credentials. It also clarifies that the gateway enforces the grant on every request, which is non-obvious behavior an agent needs to know.

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 focused sentences front-load the action and scope, then add the approval constraint, access timing, and credential behavior. Every sentence adds information with no filler or repetition.

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?

For a 6-parameter workflow tool, the description covers the request object, approval process, field narrowing, access timing, and credential handling, complementing a 100%-covered schema. It does not mention how the caller learns the request outcome or that springroll.connect.access_status can be used afterward, which is the only notable gap.

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?

Schema description coverage is 100%, so the schema already documents all six parameters, including field naming and context. The description reinforces the overall intent ('exact fields') and environment scope but does not add meaning beyond the schema, matching the baseline of 3.

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?

The description opens with a specific verb and resource ('Requests access to a data product') and adds the scope 'for one environment' and 'naming the exact fields the application needs.' This clearly identifies the operation and distinguishes it from status or approval sibling tools without requiring schema inspection.

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?

It gives clear context: call this when an application needs a data product's fields, expect an approval step, and know that nothing is readable until approval. It does not explicitly name alternatives like springroll.connect.access_status or when not to call it, so it stops short of a full 5.

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