debugging

debugging is a skill for Claude Code, Codex from GDvega/super-android-kotlin-firebase-skill. It costs 37 tokens per session (598 once invoked), scanned A, original, MIT.

A guide for diagnosing Android build failures, Gradle problems, crashes, application-not-responding errors, and related runtime issues. It uses evidence such as error messages, stack traces, Logcat, adb, and Crashlytics.

In plain words
What is it for?
Use it to investigate failed builds or syncs, runtime crashes, ANRs, and Firebase Crashlytics reports, then reproduce and verify a targeted fix.
Why use it?
It helps isolate the first real cause from follow-on errors and keeps fixes small, rather than changing many dependencies or deleting useful evidence.

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

debugging 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Find root causes with evidence and apply minimal fixes.

When to use

  • A build, sync, runtime crash or ANR occurs.
  • Logcat, adb or Crashlytics evidence needs triage.
  • A minimal reproduction is needed.

Inputs to inspect

  • Exact command that failed.
  • Full stacktrace and first error.
  • Relevant Gradle versions and files.
  • Reproduction steps and device/API.

Required workflow

  1. Separate first cause from downstream noise.
  2. Locate the file or config responsible.
  3. Apply one minimal fix.
  4. Re-run the failing command.
  5. Document remaining uncertainty and next diagnostic step.

Rules

  • Do not shotgun-update dependencies.
  • Do not delete caches as the main solution.
  • Do not silence warnings that indicate real incompatibility.
  • Preserve crash evidence.
  • Mention local-only issues separately.

Local skills to invoke

  • gradle-build
  • testing
  • firebase-crashlytics-analytics
  • code-review-refactor

External companion skills to use when installed

Do not assume these companion skills are installed. Prefer the local skills above first, then consult Companion Skills for install and verification commands.

  • skydoves/android-testing-skills — use for deeper Android or Compose UI testing, semantics, assertions or test workflow guidance.

Files commonly touched

  • build.gradle.kts
  • Gradle logs
  • Logcat output
  • Crashlytics reports
  • source file in stacktrace

Commands to validate

./gradlew --stacktrace <task>
./gradlew build --scan
adb logcat
adb bugreport
./gradlew test

Common mistakes to avoid

  • Fixing the last error instead of the first cause.
  • Changing many versions at once.
  • Ignoring device/API-specific reproduction.
  • Removing code without explaining risk.

Checklist

  • First cause identified.
  • Minimal fix proposed.
  • Verification command given.
  • Reproduction documented.
  • Risk/rollback noted.

Example prompts

  • Use $super-android-kotlin-firebase to debug this Gradle error.
  • Use $super-android-kotlin-firebase to triage this Crashlytics stacktrace.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

debugging is a skill published in the GitHub repository GDvega/super-android-kotlin-firebase-skill (2 stars, last pushed 2mo ago), licensed MIT. It adds 37 tokens to every session and 598 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
