manage_app_registrations

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

Given no annotations, the description carries the burden of behavioral disclosure. It does reveal action-specific parameters (e.g., delete_registration requires confirm=True) and distinguishes mutating operations (delete, enable, disable) from read-only ones. However, it omits consequences, permission requirements, or reversibility of destructive actions, leaving a moderate gap.

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?

The description is well-structured: a short overview followed by a bulleted list of action-value pairs. Each line is concise and necessary given the tool's multi-action nature. It could be slightly more compact, but the format is efficient and readable.

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?

The action catalog with parameter hints covers the core usage and leverages the output schema for return values. However, it leaves some input parameters (top, body) unexplained and does not provide context on authentication, pagination, or destructive-action safeguards beyond the confirm flag, so completeness is moderate for a tool of this complexity.

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?

With schema description coverage at 0%, the description compensates by mapping each action to its relevant parameters (e.g., search_registrations → search_term, get_expiring_credentials → days_until_expiry). It notably clarifies that confirm=True is needed for deletion, adding meaning beyond the schema's default false. However, parameters like top and body remain undocumented, preventing a 5.

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 begins with 'Manage Entra ID app registrations and enterprise apps (service principals)', clearly stating the tool's scope. The subsequent action list enumerates specific verbs (list, get, search, delete, enable, disable) applied to concrete resources, fully distinguishing it from sibling tools like manage_entra_users or manage_intune_devices.

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 description clearly implies the tool is for any app registration or enterprise app management task. However, it does not explicitly provide 'when not to use' guidance or name alternative tools for other Entra ID resources, stopping short of a perfect score.

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