**Augustus** — named for Augustus De Morgan (1806–1871), mentor and professor of William Stanley Jevons — is an agent skill for designing judgment-assisted systems with [TypeSafe](https://docs.typesafe.ai/) Jev System One models. Code stays in control; Jev supplies narrow, typed semantic judgments (Choice, Score, Noul) that software can act on directly.

Companion, not replacement, to the official [`typesafe-ai` skill](https://github.com/typesafe-ai/skills). That skill owns integration contracts; Augustus owns the **design judgment**: which classical methods map onto Jev primitives, what breaks in translation, and what experiment would prove a design wrong.

The skill

.agents/skills/augustus/SKILL.md — working protocol + decision-design card
.agents/skills/augustus/references/mappings.md — 5 classical-method mappings with boundaries, counterexamples, acceptance tests
.agents/skills/augustus/references/validation.md — design gate, eval recipes, Jev-for-skills (routing, self-monitoring, testing, modularity, frontmatter)
.agents/skills/augustus/references/boundary-audit.md — existing-system insertion: fit test, opportunity map, smallest boundary, red flags
.agents/skills/augustus/scripts/evaluate_decisions.py — offline evaluator for selective binary decisions (Brier, reliability, threshold/cost sweep)

Plus `research/` — the living evidence archive behind the skill, refreshed hourly (see `research/README.md`).
