six-sigma-challenge skillA
six-sigma-challenge is agent-read markdown (skill) from stempeck/agentfactory: Challenges the quality of any completed review or assessment to determine what would achieve six-sigma (99.9999%) quality outcome. Works with scored reviews (X/10), qualitative reviews (PASS/FAIL), or unstructured assessments. Identifies gaps, independently discovers missed issues, stress-tests each proposed improvement for feasibility including logical impossibilities, and appends a "Six-Sigma Caveats" section. Use when a review is less than perfect, when the user asks "what would make this per.

Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent.

What the file says
# Six-Sigma Challenge Challenge any quality assessment to find the gap between current outcome and perfection. ## Inputs | Input | Required | Source | |-------|----------|--------| | Review file | Yes | First argument, or `todos/ultra-implement/blind_review.md` | | Target document | Yes | Second argument, or auto-detected (see below) | **Invocation**: `/six-sigma-challenge <review-file> <target-document>` **Default**: `/six-sigma-challenge` (uses ultra-implement defaults) **Auto-detection for target document** (when no second argument): 1. Read `todos/ultra-implement/investigation_report.md` and extract the `Problem File:` path 2. If that file exists, use it as the target document 3. Fallback: `todos/ultra-implement/COMPLETION.md` This ensures the caveats append to the original problem file regardless of what `/ultra-implement` was invoked with. ## Phase 1: Extract Quality Gaps Read the review file. Identify every area where the outcome falls short of perfection. **For scored reviews** (X/10 criteria): Record each criterion below 10/10, the deficit, and the reviewer's reasoning. Rank by deficit size. …
