What it does
Install Firecrasher is an agent skill from osama-raddad/FireCrasher. Add the FireCrasher crash-recovery library to an Android app and install it in the Application class. Use when integrating FireCrasher, setting up crash recovery, or when "app crashes should recover instead of closing".
Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Mobile, covering Android development. It works with Android, Gradle and Java. The repository describes itself as: FireCrasher is a Uncaught Exceptions recovery library for android. The licence is Apache-2.0.
When your agent uses it
- Integrating FireCrasher
- Setting up crash recovery
- App crashes should recover instead of closing
Example prompts
- “app crashes should recover instead of closing”
- “/install-firecrasher”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 7a06228. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are kotlin, groovy and xml).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
jitpack.io
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Install Firecrasher loads about 562 tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 179 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Add the FireCrasher crash-recovery library to an Android app and install it in the Application class. Use when integrating FireCrasher, setting up crash recovery, or when "app crashes should recover instead of closing".
Install FireCrasher
FireCrasher catches uncaught main-thread exceptions and recovers the app (restart the activity → go back → restart the app) instead of letting it die. It is distributed via JitPack.
Requirements
- minSdk 23 or higher.
- A toolchain that accepts Java 21 bytecode / Kotlin 2.1+ metadata (AGP 8.2+).
1. Add the JitPack repository
In settings.gradle (or the root build.gradle for older setups):
dependencyResolutionManagement {
repositories {
google()
mavenCentral()
maven { url 'https://jitpack.io' }
}
}2. Add the dependency
In your app module's build.gradle:
dependencies {
implementation 'com.github.osama-raddad:FireCrasher:3.0.0'
}3. Install in your Application class
Installation must happen in Application.onCreate, before any activity is
created — FireCrasher hooks the main looper and activity lifecycle there. A
bare install already recovers automatically at the evaluated level:
class App : Application() {
override fun onCreate() {
super.onCreate()
installFireCrasher()
}
}To take over crash handling, configure onCrash (see the report-crashes and
customize-recovery skills for reporting and custom UX):
installFireCrasher {
onCrash {
// `throwable`, `activity`, `level`, `retryCount` are in scope.
recover()
}
}Register the Application in your manifest if it isn't already:
<application android:name=".App" ... />Verify
Build and run, then throw from a screen (e.g. a button handler) to confirm the app recovers instead of closing:
button.setOnClickListener { throw RuntimeException("boom") }Next
report-crashes— forward the crash to your crash reporter.customize-recovery— show a loading/recovery UI based on the recovery level.detect-native-crashes-and-anrs— capture crashes the handler can't see.
