Owner

Adds two new skills, cherry-picked clean onto current main (80 skills total). Two independent commits — split into separate PRs on request.

r-ops — modern R (new)

Tidyverse-first R reference, the first data-science skill in the set. SKILL.md routes an import → tidy → transform → visualize → model → communicate workflow across 9 reference files (~4,000 lines): tidyverse-core, import-io, strings-dates-factors, visualization, iteration-functional, modeling-stats, data-table, time-series, workflow-tooling. Leads with current idioms (native |>, dplyr .by=, the \(x) lambda, list_rbind); flags base R and data.table where they win.

supply-chain-defense — behavioural supply-chain defense (new)

Proactive sibling to security-ops. Socket.dev scanning, a pre-install-scan.sh PreToolUse hook (advisory; SUPPLY_CHAIN_BLOCK=1 for a hard gate), stale-OIDC audit, dependency cooldown, exposure-check (IOC catalog), self-integrity scan. Ships rules/supply-chain.md + 4 references + 3 scripts.

Wiring

Both registered in plugin.json + README skill table; counts updated (80 skills, 6 hooks, 7 rules). No version bump and no Recent Updates blocks — version sequencing is the release owner's call (main has a pending v2.9.0 of its own).

Stacking

Based on chore/secret-scan-hygiene (#5) so it inherits the .gitleaksignore and clears the push-gate. Merge #5 first, then this retargets to main.

Behavioural-first defense against the 2026 supply-chain worm campaign
(Shai-Hulud / Mini Shai-Hulud). Proactive sibling to the reactive
security-ops: npm audit / pip-audit are advisory-driven and blind in the
window before an advisory exists, so this leans on Socket.dev behavioural
scanning (free CLI + no-key depscore MCP), a pre-install-scan.sh PreToolUse
hook (advisory by default, SUPPLY_CHAIN_BLOCK=1 for a hard gate), stale-OIDC
audit, a 7-day dependency cooldown, and a read-only self-integrity scan for
worm persistence hooks injected into Claude Code / VS Code / MCP configs.

Ships rules/supply-chain.md (global doctrine), four references (threat model,
Socket CLI/MCP/pricing, hardening checklist, free/OSS tooling landscape) and
three Axiom-protocol scripts (integrity-audit, preinstall-check, exposure-check
with a seeded IOC catalog). Also adds the missing security-ops row to the
README skill table.

(cherry picked from commit 85d9d9b8ee51c8010e4b82cbd43582ff503087c5)
Tidyverse-first, current-best-practice R reference (the first data-science
skill in the set). SKILL.md routes an import -> tidy -> transform -> visualize
-> model -> communicate workflow across nine references (~4,000 lines):
tidyverse-core, import-io, strings-dates-factors, visualization,
iteration-functional, modeling-stats, data-table, time-series, and
workflow-tooling. Leads with the modern stack (native |>, dplyr .by=, purrr,
ggplot2, broom/tidymodels, tsibble/fable, Quarto/renv) and flags base R and
data.table as the right tool when they are.
