FireCrasher: Skill for Claude Code

.claude/skills/run-checks/SKILL.md

run-checks is a skill for Claude Code from osama-raddad/FireCrasher. It costs 59 tokens per session (419 once invoked), scanned A, original, Apache-2.0.

A procedure for running the same checks locally that FireCrasher runs in continuous integration, the automated build system that tests code after changes.

In plain words
What is it for?
Running the full Gradle build on JDK 21, or checking unit tests, Android lint, and ABI compatibility separately. ABI compatibility checks whether a library's public interface changed.
Why use it?
It catches failing tests, Android lint errors, and unintended public API changes before code is pushed or submitted for review.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

run-checks scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Run the CI-equivalent checks

CI (.github/workflows/build.yml) runs ./gradlew build --stacktrace on JDK 21. build depends on check, which runs the unit tests, Android lint (abortOnError = true), and :firecrasher:apiCheck (the ABI baseline comparison). Reproduce it locally before pushing.

Steps

  1. Confirm the toolchain is JDK 21 (java -version). AGP 9.x + the Java 21 bytecode target require it.
  2. Run the full build:
    ./gradlew build --stacktrace
    
  3. For a faster inner loop while iterating, run the pieces directly:
    ./gradlew :firecrasher:test        # Robolectric unit tests
    ./gradlew :firecrasher:lint        # Android lint
    ./gradlew :firecrasher:apiCheck    # ABI baseline comparison
    

If it fails

  • Test failures — reports are under firecrasher/build/reports/tests/.
  • Lint failures — reports under firecrasher/build/reports/lint-results-*. Lint is set to fail the build; fix the finding rather than lowering severity.
  • apiCheck failure — the public API changed. If the change was intentional, use the update-abi-baseline skill; if not, it means you leaked something into the public surface — revisit the change.

Do not weaken abortOnError, delete tests, or edit the ABI baseline just to get green. Fix the underlying cause.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
