Based on SOC occupation classification
Context engineering — memory navigation, textual graph traversal, progressive disclosure, recovery. Load when assembling context for a task or when lost.
Implementation-side security discipline — headers, dependencies, secrets, authz. Load for hardening work (sec-ops domain).
Commit conventions, branching, anchors in messages, and the git safety rules. Load for any git operation beyond status/diff.
Anti-generic-AI design discipline — bans, tells, and the slop test. Load for ANY new UI surface or visual redesign. Inspired by Impeccable (Apache 2.0).
Motion & animation discipline — purpose, performance, reduced-motion. Load when work involves animation, transitions or scroll effects.
Microcopy discipline — buttons, errors, empty/loading/success states, alt text. Voice and tone come from the project's memory, not from this skill.

Stack-agnostic: frameworks come from memory-long §stack; targets from TESTS.md. This is the discipline layer.
.only/.skip), assertions on internals, test-order dependence, weakening coverage configs to pass (hook-enforced)Unit ~70% (fast, isolated, logic) · Integration ~20% (boundaries: API contracts, DB access) · E2E ~10% (critical user paths only — expensive, flaky-prone).
The unit under test · the project's type system · pure functions · time/randomness (inject instead). Mock only true boundaries: network, filesystem, third-party services, clocks.
Each test: one behavior, named as a sentence (rejects expired tokens), arrange-act-assert visible, failure message diagnosable without reading the test body.
