RunPackageTests

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

No annotations are provided, so the description carries the full burden. It usefully discloses the execution model (runs tests across every test-enabled object) and that results are aggregated, but says nothing about side effects, permissions, runtime, or whether the returned aggregation is pass/fail counts vs. detailed messages.

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?

One tight sentence with the action front-loaded and no filler; 'and retrieve aggregated results' earns its place by signaling the return behavior. It is arguably a touch terse given everything an agent must infer, but nothing is wasted.

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 test-execution tool with no output schema and no annotations, the description leaves notable gaps: the shape of 'aggregated results', whether non-test-enabled objects are skipped silently, and any activation or authorization prerequisites are all unspecified.

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?

Single parameter with 100% schema description coverage ('Name of the ABAP package'), so the schema already fully documents it. The description only restates that the package is the unit of work and adds no format or naming-convention detail beyond the 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?

States a specific verb (Run unit tests) and a clear scope (all test-enabled objects in a package), plus the outcome (aggregated results). It is distinguishable from the package-scoped siblings like GetPackage/GetPackageContents, but it never explicitly contrasts itself with RunClassTests, the obvious neighboring alternative.

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?

The package-wide scope implicitly tells an agent when this applies versus a single-object runner, but there is no explicit when-to-use guidance, no prerequisites (e.g. objects must be activated), and no named alternative such as RunClassTests.

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