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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, fully covering the safety profile. The description's 'does not create content or start paid work' largely restates that profile, adding minor emphasis but no new behavioral detail such as what 'open' does operationally.

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?

Two short sentences, front-loaded with the action and resource, and the boundary clause is compact. No filler, though the domain enumeration is slightly long relative to the information it conveys.

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?

An output schema exists and annotations carry the safety contract, so return values and side-effect behavior need not be described. The definition adequately frames a read-only entry-point tool, though the `view`/`brandId` usage remains opaque.

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 0% for two parameters, so the description must carry the load. Its listed domains (brands, campaigns, media, reports, automations, Market Intelligence) loosely echo several `view` enum values, but it never explains the `view` selector or the `brandId` scoping parameter, leaving gaps.

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 verb+resource ('Open the Publinio workspace') and enumerates the review domains it fronts. The closing negative ('Does not create content or start paid work') distinguishes it from the many create/prepare/activate siblings, though it never names a sibling directly.

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?

Provides one clear exclusion ('Does not create content or start paid work'), which is meaningful against a toolset dominated by creation tools. However, it gives no positive routing to alternatives and no prerequisites or context for when opening the workspace is the right first step.

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