Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
appIdYesThe unique identifier for the app. For Android: the package name (e.g., 'com.google.android.gm'). For iOS: the numeric ID (e.g., '553834731') or the bundle ID (e.g., 'com.midasplayer.apps.candycrushsaga').
platformYesThe platform of the app ('ios' or 'android').
countryNoTwo-letter country code for store localization (e.g., 'us', 'de'). Affects availability and potentially some metadata. Default 'us'.us
langNoLanguage code for the results (e.g., 'en', 'de'). If not provided, defaults to the 'country' code. If 'country' is also missing, defaults to 'en'. Determines the language of text fields like description and recent changes.en

Implementation Reference

  • server.js:154-269 (handler)
    Handler function that implements the get_app_details tool. Fetches detailed app information from Google Play Store (using google-play-scraper) or Apple App Store (using app-store-scraper) based on the platform. Normalizes the response data and returns it as JSON text content. Handles both numeric IDs and bundle IDs for iOS.
    async ({ appId, platform, country, lang }) => {
  try {
    let appDetails;
    
    if (platform === "android") {

Tool Definition Quality

D1/5.0
Behavior1/5

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

Tool has no description.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness1/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Tool has no description.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Tool has no description.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Tool has no description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose1/5

Does the description clearly state what the tool does and how it differs from similar tools?

Tool has no description.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Tool has no description.

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