gradle_build

Build Android apps with Gradle in a project directory and retrieve the produced APK paths. Supports custom tasks and extra Gradle arguments.

Instructions

Build the app with Gradle (default task assembleDebug) in project_dir, and report the produced APK path(s). project_dir must contain the Gradle wrapper (gradlew). Runs on the host, not a device.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
argsNoExtra arguments passed to Gradle (e.g. --stacktrace, -Pflavor=free).
jsonNoFor run_unit_tests/run_instrumented_tests: return the test summary as structured JSON (per-suite timing, full failure stack traces) instead of the human-readable text summary. Ignored by gradle_build and list_gradle_tasks.
taskNoGradle task to run. Defaults to the tool's standard task.
project_dirNoPath to the Android project root containing the Gradle wrapper (gradlew). Optional if session_set_defaults has pinned a project_dir for this session.

TDQS

A4.1/5.0
Behavior3/5

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

With no annotations, the description carries the full burden. It discloses the core behavior (build, report APK paths, default task, host execution) and a prerequisite. It does not mention potential side effects, error conditions, or execution time, but the disclosed information is sufficient for basic understanding.

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 three concise sentences with no fluff. Each sentence adds essential information: purpose and default, prerequisite, and host-vs-device distinction. The structure is logical and front-loaded.

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

Completeness3/5

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

The description covers the basic purpose, default, prerequisite, and host execution. However, it lacks details on the return format of APK paths, error handling, and potential timeouts. With no output schema, more explanation of the return value would improve completeness.

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

Parameters4/5

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

Schema coverage is 100%, so baseline is 3. The description adds value by stating the default task (assembleDebug) and clarifying that the json parameter is ignored by this tool. This goes beyond the schema descriptions.

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 description clearly states the tool builds the app with Gradle, specifies the default task assembleDebug, and reports produced APK paths. It distinguishes from siblings like build_and_run by noting it runs on the host, not a device.

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

Usage Guidelines4/5

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

The description provides a clear prerequisite (project_dir must contain gradlew) and a key usage distinction (runs on host, not device). However, it does not explicitly name alternative tools or state when not to use this tool.

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