systematic-debugging

systematic-debugging is a skill for Claude Code, Codex from rabee-elkholy/android-harness-kit. It costs 27 tokens per session (206 once invoked), scanned A, original, MIT.

A debugging guide for finding the cause of bugs, crashes, and unexpected behavior in Android apps. It requires developers to state possible causes, trace what happens, reproduce the problem, and inspect the full error log before changing code.

In plain words
What is it for?
Use it to investigate Android failures, form and test possible explanations, follow data from the triggering action to the failure, and apply a root-cause fix.
Why use it?
It reduces guesswork and helps avoid fixes that merely hide symptoms, such as ignoring errors or returning fake data.

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

systematic-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 1mo 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

Systematic Debugging Skill (Superpowers Protocol)

1. Root Cause Hypothesis Framework

Do NOT guess code fixes. MANDATORY for ALL bug fixes without exception:

  1. Formulate Explicit Hypotheses: List 2–3 potential causes.
  2. Isolate State & Triggers: Trace data flow from trigger to failure point.
  3. Log & Trace Inspection: Read full un-truncated stack trace or ADB logcat before forming conclusions.
  4. Reproduce & Test Hypothesis: Verify hypothesis against empirical evidence before modifying code.

2. Prohibition of Symptom Swallowing

  • Never resolve bugs by swallowing exceptions, adding empty try-catch, or returning fallback 0/null dummy data.
  • Always fix the root condition at the data producer level.

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.
