appgallery_get_access_token

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

No annotations provided, so description must carry full burden. It discloses the OAuth2 grant type ('client_credentials') and the token's purpose. Missing details like token lifetime, security prerequisites, or side effects beyond generation. Acceptable but minimal.

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?

Single sentence of 15 words, instantly communicates purpose and prerequisite. No filler or repetition. Front-loaded with essential information.

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?

Given zero parameters and no output schema, description sufficiently covers the tool's role and prerequisite. Lacks explicit mention of any required configuration steps, but for a simple token getter, it is largely complete.

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?

No parameters defined; schema coverage is 100%. The description implicitly explains the absence by mentioning 'client_credentials' (implying pre-configured credentials). Adds value by clarifying the authentication flow, so baseline 4 is appropriate.

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?

Clear action ('Generate/refresh'), specific resource ('AppGallery Connect API access token'), and protocol ('client_credentials') with explicit linkage to the Publish API. Differentiates from sibling token tools like 'huawei_get_access_token' by naming the platform and use case.

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?

States that the token is 'required for the Publish API', giving a clear when-to-use context. However, it does not explicitly mention when not to use or compare to alternatives like 'appgallery_api_request' for direct calls.

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