The server provides 3 tools with partial schema coverage and descriptions of varying quality. All tools have descriptions that meet the 20-character minimum, and all expose input schemas (though some params lack full context). The naming follows verb_noun patterns (list, get) which is solid. However, the generated tools lack error handling guidance, output schemas are not documented, and parameter descriptions are minimal. The 'account' parameter is repeated across all tools but not well-contextualized. The server is deployed via HTTP transport with OAuth security, which is good. The main gaps: output schemas are undocumented, error recovery paths are unclear, and generated tools (appsmarket_*) have truncated descriptions. This is solidly above F but below B-grade work.

• Fix truncated descriptions in appsmarket tools, regenerate or manually cap at 1024 chars, ensuring complete sentences.
• Document the output schema for each tool. For account_list, specify: returns array of {alias: string, email: string, admin: boolean, token_health: enum(ok|expired_refreshable|needs_reauth|missing|decrypt_error), granted_scopes: string[], configured_scopes: string[]}. For appsmarket tools, specify the fields returned by the Google API (customerId, applicationId, skuId, status, etc.).
• Add error handling guidance to each tool description. E.g., account_list: 'If no accounts are listed, run the auth command to add one. If token_health is expired_refreshable, refresh the token; if needs_reauth, re-authenticate.' Appsmarket tools: 'If applicationId or customerId is invalid, check the IDs in the Google Admin console. If licensing status cannot be determined, the app may not be installed.'
• Enhance the 'account' parameter description: 'Google account alias (e.g., main, work). Aliases are configured during OAuth setup via the auth command. Call account_list to see available aliases and their health status.' Add validation error message in tool implementation: 'Invalid account alias. Available aliases: [list].'
• Clarify the 'fields' parameter: 'Google API response field mask. Use to return only specific fields (e.g., customerId,skuId,status) to reduce response size. If omitted, returns all fields. See Google Admin API documentation for valid field names.'
• Consider splitting appsmarket tools or adding a discovery tool (e.g., appsmarket_apps_list) to help agents find valid applicationId values. The current parameter descriptions assume agents already know the app IDs.
