Get an app

apps_get_app

Read-onlyIdempotent

One app's store listing: rating, installs, version, release notes, description, screenshots and the developer's contact details.

Use when: "tell me about this app", "how is competitor's app rated", "who makes this app and how do I reach them", "when did they last ship an update". Not for: what users say, use apps_get_reviews. Store searches the app ranks for, use apps_get_keywords. Finding apps, use apps_search_apps or apps_get_top_charts. Returns: Record. title, subtitle (App Store only), description, category, genres[], rating (out of 5), ratings_count, installs (Google Play only), price (0 when free), content_rating, version, released_at, updated_at, update_notes, developer with its website, email and address (those three Google Play only), screenshots[], similar_apps[] and more_by_developer[] (app_id, title). null = the store does not show it. On the App Store, description starts with the promotional text when the app has one, category is sometimes null, and currency is null on free apps. On Google Play, version is often null. Cost: 1 credit. Cached 1 day. Can take up to a minute. Example: {"store": "google_play", "app_id": "com.Slack"}

TDQS

A4.7/5.0

Behavior5/5

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and non-destructive behavior, but the description adds substantial operational context beyond that: cost of 1 credit, 1-day caching, possible latency up to a minute, null semantics, and store-specific field quirks. These details help the agent set expectations and handle missing data correctly.

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

Conciseness5/5

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

The description is front-loaded with the resource and its returned fields, then follows a predictable Use when / Not for / Returns / Cost / Example structure. Despite its length, every section adds actionable information for a complex, open-world tool, and there is no filler.

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

Completeness5/5

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

Even though an output schema exists, the description supplies critical context it cannot: per-store field differences, nullability rules, credit cost, caching, and latency expectations. Combined with the example and sibling routing, it gives the agent everything needed to call the tool correctly and interpret its results.

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

Parameters3/5

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

Schema description coverage is 100%, so the schema already documents all six parameters, including the store enum and app_id format. The description only adds a concrete example invocation and does not explain dry_run, max_credits, language, or location beyond what the schema says, so the baseline of 3 applies.

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

Purpose5/5

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

The first sentence names the specific resource and enumerates the data returned (rating, installs, version, release notes, description, screenshots, developer contact), distinguishing this as an app store listing lookup. The 'Not for' section explicitly routes the agent away from apps_get_reviews, apps_get_keywords, apps_search_apps, and apps_get_top_charts, so the tool is clearly separable from its closest siblings.

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

Usage Guidelines5/5

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

It provides explicit 'Use when' triggers and a 'Not for' section that names the correct alternative tool for each adjacent need. Nothing is left to inference about when this tool is the right choice versus apps_get_reviews, apps_get_keywords, apps_search_apps, or apps_get_top_charts.

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