systematic-debugging

systematic-debugging is a skill for Claude Code from DDS-Solutions/AI-TadPole-OS. It costs 25 tokens per session (981 once invoked), scanned A, original, MIT.

A four-phase method for debugging software by reproducing the problem, finding its root cause, applying a fix, and checking the result with evidence.

In plain words
What is it for?
Use it to investigate bugs in applications, APIs, command-line tools, and end-to-end flows, then verify that the fix resolves the original failure.
Why use it?
It replaces guesswork with a repeatable investigation and requires a failing test or other tight reproduction before changing code.

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 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.

Systematic Debugging

Source: obra/superpowers

Overview

This skill provides a structured approach to debugging that prevents random guessing and ensures problems are properly understood before solving.

4-Phase Debugging Process

Phase 1: Reproduce & Tighten Feedback Loop

🛑 STRICT GATE: Do NOT touch code or hypothesize fixes until a tight, red-capable reproduction command is built and verified.

Build the tightest possible feedback loop in roughly this order:

  1. Failing test (unit, integration, e2e) asserting the exact symptom.
  2. Curl / HTTP script against a local endpoint.
  3. CLI invocation diffing stdout/stderr against expected fixture.
  4. Captured trace / payload replay through isolated code path.
Feedback Loop Quality Criteria
  • Red-Capable: Drives the actual bug code path and fails on the user's exact symptom (not just "didn't crash").
  • Deterministic: Returns identical pass/fail verdict on 100% of runs (for flaky bugs, loop 100x to raise repro rate).
  • Fast: Completes in < 2 seconds.
## Reproduction Gate Sign-off
- Command Executed: `<exact command line>`
- Output Log: `<pasted red failure log>`
- Loop Duration: `<seconds>`

Phase 2: Isolate & Discriminative Probe

Narrow down the source using evidence and active hypothesis discrimination (Schema Harness protocol).

## Isolation & Discriminative Probing
- When did this start happening?
- What changed recently?
- Does it happen in all environments?

### Hypothesis Discrimination (Probing Protocol)
Formulate two competing hypotheses and design an active probe:
- **Hypothesis A (H_A)**: [Proposed cause A] -> Expected probe outcome: [Outcome A]
- **Hypothesis B (H_B)**: [Proposed cause B] -> Expected probe outcome: [Outcome B]
- **Discriminative Probe Execution**: Execute non-destructive test to falsify one hypothesis.

systematic-debugging is a skill published in the GitHub repository DDS-Solutions/AI-TadPole-OS (8 stars, last pushed 2d ago), licensed MIT. It adds 25 tokens to every session and 981 once invoked, about $0.0001 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 2026-09-03.
