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

Beyond the readOnly/idempotent annotations, the description discloses real behavioral traits: unavailable sections are explicitly marked, unknown balances must not be treated as zero, dates are UTC and need local-time conversion, and app results are paginated. These are output-semantics caveats that neither the annotations nor the (absent) output schema provide.

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 payload contents are front-loaded in the first sentence, followed by two short mode-specific sentences and two short caution sentences. There is no filler; every clause either scopes the tool or prevents a specific agent mistake.

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?

With no output schema, the description carries the burden of describing return values, and it does so completely: it lists each returned section, explains the pagination contract, and warns about unknown/unavailable data and UTC dates. An agent has everything needed to call it and interpret the response.

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 three parameters are already fully documented, including profile_only's skip behavior and limit's default/maximum. The description's mentions of profile_only and continuation_token largely restate the schema rather than adding syntax, format, or constraint detail, so the 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 subject (the connected AppDeploy user) and enumerates exactly what the account overview returns: profile, a page of apps, subscription/renewal state, monthly credits with reset date, and top-up credits with expiry. That enumeration distinguishes it from the plain app-listing siblings like get_apps without needing to name them.

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?

It gives clear conditional guidance for its two optional modes: set profile_only to true for just the user, and use continuation_token to read more apps. It never names an alternative sibling tool or states when a different tool would be the right call, so it stops short of explicit when/when-not routing.

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