List registered Entra applications

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 discloses the underlying command ('pac admin application list') and the execution context (active pac auth profile), which implies a read-only listing operation, but it says nothing about returned fields, pagination/volume, or required admin permissions.

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 with the purpose front-loaded and the implementation detail second. Nothing is wasted, though the content is sparse enough that it borders on under-specification rather than tightness.

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 no-argument list tool with full schema coverage and no output schema, the essentials are covered. However, in a sibling cluster containing list_service_principals and list_app_templates, the absence of any disambiguation leaves the agent to guess which lister fits the task.

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 all four parameters (cwd, profile, background, timeoutSeconds) are already documented. The description's mention of the active auth profile aligns with the profile parameter but adds no syntax or meaning beyond the schema; baseline 3 applies.

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 names a specific resource (Entra applications registered with the tenant for Power Platform), so an agent knows this is a listing operation over tenant-registered apps. It does not explicitly differentiate from near siblings like cs_admin_list_service_principals or cs_admin_list_app_templates, but the resource is distinct enough to be actionable.

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?

There is no when-to-use guidance, no prerequisites, and no named alternative. The agent must infer that this is the right tool when it wants registered applications rather than service principals or app templates, all of which are separate sibling tools.

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