Register a control-app token under an alias

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

Describes verification behavior (fetching metadata by default) and token security (never returned). Annotations already note readOnlyHint=false and destructiveHint=false; description adds useful context beyond these.

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 focused sentences plus a terse listing of args and return. No unnecessary words; every part earns its place.

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?

Covers core behavior and return structure but does not address idempotency (whether re-registering with same alias updates or errors) or error conditions. With no output schema, more detail on verification failure could improve completeness.

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?

All 5 parameters are documented in the schema (100% coverage). The description adds value by explaining the token security implication and default verification behavior, which go beyond schema descriptions.

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?

Clearly states the tool stores a Singular app token under a friendly alias for later reference, with specific mention that the raw token is never returned. Distinguishes from sibling tools like singular_remove_app or singular_list_apps.

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?

Implicitly indicates use when needing to register an app token for alias-based referencing, but does not provide explicit when-to-use or when-not-to-use guidance compared to alternatives like singular_remove_app.

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