apqp

apqp is a skill for Claude Code, Codex from RBraga01/Quality-Engineering-Skills. It costs 89 tokens per session (2,242 once invoked), scanned A, original, MIT.

A structured quality-planning method for taking a new product or part from initial planning through production launch. It divides the work into five phases, with deliverables and review points for each phase.

In plain words
What is it for?
Use it to plan an APQP project, track phase deliverables, run launch-readiness reviews, prepare status reports, or audit a supplier’s quality planning.
Why use it?
It prevents important launch and quality work from being missed or left incomplete before Start of Production (the point when regular manufacturing begins).

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

apqp 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 10d 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.

Advanced Product Quality Planning (APQP)

When to use

Use this skill when:

  • A new product or part is being launched and a structured quality plan is needed
  • Managing an APQP project and tracking deliverables across phases
  • Conducting an APQP gate review to assess launch readiness
  • A customer requests an APQP status report or phase completion confirmation
  • Auditing whether a supplier's APQP process is adequate

Prerequisites

  • Customer requirements, specifications, and drawings (or RFQ package)
  • Programme timing (SOP date, PPAP submission date, prototype gates)
  • Nominated APQP team (cross-functional: engineering, quality, purchasing, manufacturing, logistics)
  • Customer APQP template if OEM-specific format required

Workflow

Overview — The 5 APQP Phases

  approval         build           build           submission          Production

All phases run with concurrent engineering — phases overlap and teams work in parallel.


Phase 1 — Plan and Define Program

Objective: Understand customer requirements and define what the product must do.

Key deliverables:

Deliverable Description
Voice of the Customer (VOC) Customer wants, needs, expectations — translated to measurable requirements
Design Goals Product performance targets derived from VOC
Reliability and Quality Goals Target failure rate, warranty targets, Cpk targets
Preliminary Bill of Materials Draft BOM from design intent
Preliminary Process Flow High-level process sequence
Preliminary Special Characteristics Initial list of critical/significant characteristics
Product Assurance Plan Quality plan for the programme
Management Support Signed-off programme charter with resources and timing

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.

apqp is a skill published in the GitHub repository RBraga01/Quality-Engineering-Skills (28 stars, last pushed yesterday), licensed MIT. It adds 89 tokens to every session and 2,242 once invoked, about $0.0004 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 2026-08-30.
