What it does
Add Library Test is an agent skill from osama-raddad/FireCrasher. Add or update a Robolectric JVM unit test for the FireCrasher library. Use when changing recovery logic, crash handling, back-stack counting, exit-info reporting, or the recovery-state codec, and a test should cover it.
Its SKILL.md is about 610 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 Testing & QA, covering Unit testing. It works with Java and Android. 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
- Changing recovery logic
- Back-stack counting
- Exit-info reporting
- The recovery-state codec
Example prompts
- “/add-library-test”
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 bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Add Library Test loads about 612 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 245 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 or update a Robolectric JVM unit test for the FireCrasher library. Use when changing recovery logic, crash handling, back-stack counting, exit-info reporting, or the recovery-state codec, and a test should cover it.
Add a library unit test
The library's tests run on the JVM under Robolectric — no device or
emulator needed. They live in
firecrasher/src/test/java/com/osama/firecrasher/ and use JUnit 4. Every
behavior change to the library should come with a test.
Where behavior is tested today
| Concern | Test |
|---|---|
Recovery level selection (evaluate) | RecoveryLevelEvaluationTest (pure, no Robolectric) |
| Activity counting / back-stack depth | BackStackCountTest |
Crash delivered to the onCrash hook on the main thread | CrashHandlerTest |
| Install DSL: scope population, auto-recover default, forced-level recover | FireCrasherDslTest |
GO_BACK back dispatch (dispatcher vs. legacy onBackPressed) | GoBackDispatchTest |
ApplicationExitInfo querying (API 30+) | ExitInfoTest (@Config(sdk = [30, 36])) |
| Recovery-state encode/decode + 128-byte limit | RecoveryStateCodecTest |
Extend the matching suite when your change fits one; add a new
*Test.kt in the same package otherwise.
Conventions to follow
- Runner: annotate device-dependent tests with
@RunWith(RobolectricTestRunner::class). Pure-logic tests (likeRecoveryLevelEvaluationTest) need no runner — prefer that when possible. - Build activities with
Robolectric.buildActivity(...); drive lifecycle throughCrashHandler'slifecycleCallbacksrather than reaching into internals. - SDK-gated behavior: pin the API levels under test with
@Config(sdk = [30, 36])(seeExitInfoTest) so both the guarded and unguarded paths are exercised. - Reset global state:
FireCrasheris anobjectwith process-wide state (retryCount). Tests that call into it must clean up in@AfterviaFireCrasher.resetForTest()(seeGoBackDispatchTest) so tests don't leak into each other. - Name tests with backtick sentences describing the behavior, matching the
existing style (e.g.
`first crash restarts the activity`).
Run
./gradlew :firecrasher:testTest reports land in firecrasher/build/reports/tests/. Before finishing, run
the run-checks skill so lint and the ABI baseline are covered too.
