debugging-systematically

debugging-systematically is a skill for Claude Code from dork-labs/dorkos. It costs 27 tokens per session (2,462 once invoked), scanned A, original, MIT.

A guide to finding software bugs through observation, hypotheses, tests, and repeated analysis.

In plain words
What is it for?
Use it to define expected and actual behavior, check when a problem began, test possible causes, and iterate toward a fix.
Why use it?
It gives you a consistent way to narrow down causes instead of changing code based on guesses.

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

debugging-systematically 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 28d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (find-polluter.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Debugging Systematically

This skill provides debugging methodology — systematic approaches to finding and fixing bugs. It covers the mental models and techniques for effective troubleshooting.

For specific debugging tools: See /debug:* commands.

Core Debugging Methodology

The Scientific Method for Bugs

  1. Observe — What is actually happening?
  2. Hypothesize — What could cause this?
  3. Test — Design an experiment to verify
  4. Analyze — Did the test confirm or refute?
  5. Iterate — Refine hypothesis and repeat

The Golden Rule

Understand before you fix.

Never make changes to code you don't understand. Reading and comprehending the code often reveals the bug.

Problem Articulation

Questions to Answer First

Question Why It Matters
What should happen? Defines the expected behavior
What actually happens? Identifies the discrepancy
When did it start? Narrows the scope of changes
What changed recently? Identifies potential causes
Is it reproducible? Determines debugging approach

Rubber Duck Method

The act of explaining code line-by-line forces you to:

  • Think through logic sequentially
  • Surface implicit assumptions
  • Notice gaps in understanding
  • Catch inconsistencies

Often, the solution becomes obvious mid-explanation.

Hypothesis Formation

Common Bug Categories

Category Symptoms Check
Data Wrong values, undefined Log actual values
Logic Wrong branch, off-by-one Trace conditionals
Timing Race conditions, stale data Check async flow
State Inconsistent behavior Inspect state at each step
Integration API mismatches Verify contracts

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

debugging-systematically is a skill published in the GitHub repository dork-labs/dorkos (11 stars, last pushed today), licensed MIT. It adds 27 tokens to every session and 2,462 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
