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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true and a closed-world scope, so the safety profile is fully covered by structured fields. The description adds the useful behavioral fact that archived items are included alongside active ones and that intents come back with them, but says nothing about ordering, pagination, or result volume.

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?

A single sentence with no filler, front-loading the verb and the scope ("active and archived") before the payload note about intents. Nothing in it is redundant with the schema or annotations.

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 zero-parameter read tool this is close to adequate, and the annotations plus the phrase "their relevant intents" give a rough sense of the returned content. With no output schema, however, the description is the only source for return shape and it gives no sense of structure, fields, or result size.

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 no parameters, so there is nothing for the description to disambiguate; per the baseline for zero-param tools this sits at 4. The description correctly implies the call is unfiltered, matching the empty schema.

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 pairs a specific verb ("List") with the resource ("positioning statements") and adds scope detail ("active and archived") plus the associated intents. It clearly identifies the operation, but it never distinguishes this from sibling tools like devtune_get_positioning or devtune_list_positioning_answers, so an agent could still be unsure which to pick.

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?

Usage is only implied by the stated scope: because it returns both active and archived statements, an agent can infer this is the enumeration path rather than a single-record fetch. There is no explicit when-to-use guidance, no exclusion of alternatives, and no mention of get_positioning or list_positioning_answers.

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