8d-problem-solving

8d-problem-solving is a skill for Claude Code, Codex from RBraga01/Quality-Engineering-Skills. It costs 86 tokens per session (2,781 once invoked), scanned A, original, MIT.

An eight-step method for investigating a customer complaint or quality failure, from immediate safety action through corrective action and team recognition. The result is a documented report supported by evidence.

In plain words
What is it for?
Use it for automotive complaints, warranty issues, quality escapes, and other investigations requiring containment, root-cause analysis, corrective actions, and documented verification.
Why use it?
It gives teams a consistent way to contain a problem, find and confirm its causes, prevent recurrence, and show the customer that the issue is closed.

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

8d-problem-solving 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.

8D Problem Solving

Goal

Produce a validated, audit-ready 8D report with proven root causes and effective corrective actions that prevent recurrence — accepted by the customer and filed in the quality system.

Required Execution Checklist

Quick-reference for agents and practitioners. All items must be complete before D8 closure.

  • D0: Safety and regulatory risk assessed and documented
  • D0: Suspect material identified and physically segregated
  • D1: Cross-functional team assembled with champion identified
  • D2: Problem described with measured values, part number, quantity, and Is/Is-Not
  • D3: Containment implemented (past tense) with date and effectiveness evidence
  • D4: Root cause of occurrence identified and validated with data or experiment
  • D4: Root cause of escape identified and validated with data or experiment
  • D5: One PCA per root cause selected, with verification plan
  • D6: PCA implemented; verification data confirms zero recurrence; ICA formally removed
  • D7: PFMEA, Control Plan, and Work Instructions updated (revision numbers documented)
  • D7: Horizontal deployment assessed and actioned
  • D8: Champion sign-off obtained; customer notified of closure

When to use

Use 8D for customer-reported defects, internal escapes reaching downstream processes, field failures, or any non-conformance requiring documented root cause analysis. Mandatory for most automotive OEM customer complaints (Ford 8D, BMW G8D, VW QMSS, Stellantis).

Prerequisites

  • Defect or failure clearly identified and quantified
  • Access to affected parts, process records, and measurement data
  • Cross-functional team availability (quality, production, engineering minimum)

Workflow

D0 — Emergency Response (before the team is assembled)

Ask these questions first:

  1. Is this a safety or regulatory issue? If yes → escalate immediately, notify customer
  2. Is there any potential for a product recall or regulatory event (safety, emissions, homologation compliance)?
    • If yes → STOP the standard 8D timeline. Escalate immediately to management and regulatory owner. Do not proceed without documented management awareness. The 8D continues only with their authorisation.
  3. Are suspect parts already at the customer or in the field? If yes → launch containment now (D3) before completing D1-D2
  4. Capture initial evidence: photos, batch numbers, lot traceability, measurement data

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.
