A4/5.0

Behavior4/5

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

Annotations already establish readOnly, idempotent, non-destructive, non-open-world behavior, and the description reinforces this with "Not for changing data." It adds genuine non-annotation context with the initial-load cap of "up to 100 items," which tells the agent how much will be presented on launch.

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?

Three short, front-loaded sentences with the trigger condition first. The middle fragment "Apps, connected stores and tracked keywords" is terse to the point of being a label list rather than a sentence, but it carries content and nothing is wasted.

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 detail is not needed, and with no parameters the remaining burden is small. The description covers when to use it, what it shows, and the non-mutating nature, leaving only minor gaps such as UI/launch expectations.

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?

The tool takes zero parameters and the schema has 100% description coverage, so the baseline is 4. The description appropriately adds no parameter detail because none exist.

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?

The description gives a clear verb+resource (open AppSkyline) and clarifies the interactive browsing intent, which distinguishes it from the data-returning siblings like list_apps. It stops short of naming any sibling tool to route against, so it is clear but not fully differentiating.

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?

"Use this when someone wants to open AppSkyline and browse their workspace interactively" states the triggering condition, and "Not for changing data" gives an explicit exclusion. No alternative tool is named for the mutation case, so the routing is clear but not complete.

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