mobiai-mobile-debugging

mobiai-mobile-debugging is a skill for Claude Code from ArisGuimera/MobiAI-Core. It costs 104 tokens per session (4,736 once invoked), scanned A, original, MIT.

A step-by-step method for finding the root cause of mobile bugs, test failures, crashes, and unexpected behaviour before proposing a fix.

In plain words
What is it for?
Use it to investigate Android, iOS, Flutter, or React Native issues by gathering evidence, testing hypotheses, and explaining what caused the failure.
Why use it?
It prevents quick guesses and symptom-only patches that can hide the real problem or introduce new bugs.

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

mobiai-mobile-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 10d 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 — 379 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Systematic Mobile Debugging

Random fixes waste time and create new bugs. Quick patches mask underlying issues.

Core principle: ALWAYS find root cause before attempting fixes. Symptom fixes are failure.

Whether you also need explicit user confirmation at steps (b) and (d) depends on the scope classification inherited from the caller (or declared at Pre-flight below). Fast path: no confirmation gate, proceed autonomously. Gated path: explicit confirmation required at both steps.

Anti-Pattern: "It's Obviously X"

The most common failure mode is pattern-matching the symptom to a familiar-looking cause and proposing a fix before the evidence supports it — especially when a sub-agent or exploration returns a confident diagnosis that was never cross-checked against the code. Threading, null, lifecycle, cache, "the backend changed" — all tempting guesses. Every bug goes through the phased flow.

The scope classification only changes whether you wait for user confirmation, not whether you do the analysis. Fast path still gathers evidence, splits known vs. assumed, forms and verifies a hypothesis, and states the root cause — it just returns that result to the caller instead of pausing for approval.

The Iron Law

NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST

Pre-flight: Scope Classification

This skill inherits the scope from its caller (typically mobiai-fix-issue). If invoked standalone, classify at the start:

Fast path — work autonomously through all phases; return the verified root cause to the caller at Phase 6:

  • Clear symptom with obvious evidence (stack trace points at a specific line, log message is explicit)
  • Single root cause category (not contradictory evidence)
  • No architectural question, no cross-module mystery

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.

mobiai-mobile-debugging is a skill published in the GitHub repository ArisGuimera/MobiAI-Core (449 stars, last pushed 2d ago), licensed MIT. It adds 104 tokens to every session and 4,736 once invoked, about $0.0005 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 2026-08-30.
