xiigen-systematic-debugging

xiigen-systematic-debugging is a cursor rule for Cursor from lubochka/xiigen-general-skills. It costs 0 tokens per session (178 once invoked), scanned A, original, Apache-2.0.

A repeatable method for investigating unclear failures, regressions, or unstable behavior.

In plain words
What is it for?
Use it to write hypotheses, test them one at a time, record observations, and reduce a failure to a reproducible example.
Why use it?
It prevents random edits and keeps track of which explanations were tested and what each test showed.

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

xiigen-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 7d 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

Purpose

Make debugging reproducible and disciplined.

When to Use

Use for unclear failures, regressions, or unstable behavior.

Inputs

Symptoms, hypotheses, commands, code boundaries, observations.

Steps

  1. Write down hypotheses.
  2. Test one hypothesis at a time.
  3. Record the observation.
  4. Update the hypothesis list before changing direction.

Gates

Debugging has a clear trail of tested ideas and outcomes.

Evidence

Debug notes, command output, reduced repro, or identified culprit.

Anti-Patterns

Random edits, mixed hypotheses, and unrecorded attempts.

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.
