systematic-debugging

systematic-debugging is a skill for Claude Code, Codex from CodeInfinity1/Stram. It costs 28 tokens per session (425 once invoked), scanned A, original, MIT.

A step-by-step process for finding the underlying cause of software failures instead of guessing from error messages alone.

In plain words
What is it for?
Use it for test failures, runtime errors, broken user flows, flaky behavior, integration problems, and CI failures.
Why use it?
It makes debugging more reliable by reproducing the issue, ranking possible causes from evidence, and checking that the fix really works.

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

Purpose

Find root causes methodically. The assistant should collect current evidence, reproduce the problem when possible, form hypotheses, test them, patch narrowly, and verify the fix.

When To Use

Use for test failures, runtime errors, broken UI flows, flaky behavior, integration issues, CI failures, and "why does this not work" tasks.

Inputs And Evidence

  • Error output, logs, failing command, expected behavior, recent changes, and environment.
  • Source files, tests, config, runtime status, and reproduction steps.
  • Verification command output after the fix.

Tool Map

  • read_file
  • search_workspace
  • run_shell_command
  • python_interpreter
  • browser_live_observe
  • system_status
  • write_note

Workflow

  1. Reproduce or inspect the failure with current evidence.
  2. Define what "fixed" means before editing.
  3. Rank hypotheses from evidence, not keyword triggers.
  4. Inspect the smallest relevant code path.
  5. Make a scoped fix that preserves existing behavior.
  6. Run targeted verification and report residual risk.

Native Implementation Boundaries

  • Use Stram tools and current repo commands.
  • Do not import external reference debugging helpers or upstream scripts.
  • Do not implement deterministic error-message-to-fix maps.

Safety And Approval

  • Avoid destructive cleanup unless explicitly approved.
  • Do not mask failures by weakening tests.
  • Keep user changes intact.

Verification

  • The failing command should pass or the remaining blocker should be proven.
  • Add or update tests when risk warrants it.
  • Report exact commands run and outcomes.

Failure Modes

  • Patching the symptom while root cause remains.
  • Over-broad refactors during debugging.
  • Trusting stale logs.

References

  • Shortlist item: systematic-debugging.
  • Upstream inspiration: external reference systematic debugging reference only.
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.

systematic-debugging is a skill published in the GitHub repository CodeInfinity1/Stram (11 stars, last pushed 2mo ago), licensed MIT. It adds 28 tokens to every session and 425 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 2026-09-03.
