Portable skills library with output styles: documentation lookup, GitHub operations, dependency intelligence, UI/UX patterns, and skill crafting
React/TypeScript frontend + Go backend enforcement harness. 92 wired hooks across 101 scripts enforce patterns on every edit. Green != done: `test-warning-check` surfaces warnings on passing test/lint/type runs (DeprecationWarning, React `act()`, unhandled rejection, `@ts-ignore`); `ci-warning-audit` Stop-hook scans `gh run view --log` on green CI for deprecations / console warnings / skipped tests. 66 skills from TDD through CI-green PR, including /steelman anti-sycophancy guard + /snyk-ux-security per-path vuln sweep (JS + Go ecosystems; exploitability-triage first gate via `bun why`/`go mod why`/`govulncheck`; top-level direct dep bump first, parent dep bump second, resolutions/overrides/replace as last resort only with follow-up TODO to remove; React 18 pin + changelog-walked major bumps + no-deferral escalation; Go `snyk test --file=go.mod` + `go get -u` + `go mod tidy` + `govulncheck` verify). Session exit blocked while PR review threads remain unresolved. TypeScript escape hatches blocked at Edit. tsconfig strictness weakening blocked. Worktree isolation + branch safety hook-enforced. bun.lock + yarn.lock parity enforced (Snyk IO doesn't parse bun.lock). 21 LLM failure modes enforced: 7 Karpathy single-agent + 14 MAST multi-agent (Cemri et al. NeurIPS 2025). OWASP + STRIDE subset + snyk/bun audit. Core Web Vitals perf gate. MCP ban with CLI redirect (~20x token savings). Agent-browser wrap (~91% token reduction for AI browsing). 3-hat plan review (product/engineering/design). 9 agents (adds plan hats + karpathy reference), 5 routines. Opus 4.7 tuned, POSIX-friendly.
