Systematic Debugging

Systematic Debugging is a skill for Claude Code, Codex from ankur-gaurav161418/omniforge. It costs 20 tokens per session (190 once invoked), scanned A, original, MIT.

A method for finding the underlying cause of difficult software errors through logs, reproduction, and tested hypotheses.

In plain words
What is it for?
Reading complete error logs, creating a failing test or reproduction script, tracing where bad data starts, fixing the cause, and checking for regressions.
Why use it?
It prevents developers from fixing only visible symptoms and helps confirm that a fix does not create new problems.

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

OmniForge Systematic Debugging Skill

Purpose

Prevent superficial symptom patching by enforcing empirical hypothesis testing, full log inspection, and reproducible test cases.

Core Rules

  1. Log Inspection First: Never diagnose without reading complete, un-truncated error logs.
  2. Reproduce: Write a failing test case or reproduction script before touching application code.
  3. Isolate Root Cause: Trace dataflow upstream to locate the exact origin of failure.
  4. Fix & Verify: Apply fix, verify tests pass, ensure no regression side effects.
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.
