About

SPC Tools gives Claude a calibrated, comprehensive statistical process control toolkit with pure-JavaScript visualization. Covers standard techniques (control charts, Cpk, Gage R&R) as well as Bayesian and distribution-free methods. No dependencies required; computation is pure Python, charts are zero-dependency ChartSpec JSON rendered client-side.

# spc-tools

Statistical Process Control and quality engineering for Claude Code. Powered by the [Forge](https://github.com/ewolters) engine. Sponsored by [Svend](https://svend.ai).

## Skills

| Skill | Description |
|-------|-------------|
| `/spc-tools:control-chart` | I-MR, X-bar/R, p, c, CUSUM, EWMA charts with Nelson rules |
| `/spc-tools:capability` | Cp, Cpk, Pp, Ppk, sigma level, DPMO, yield |
| `/spc-tools:gage-rr` | Measurement system analysis (crossed/nested) |

A background `spc-spec` skill loads the complete Forge API reference automatically when you're working on quality/manufacturing analysis.
