Get Codex's second opinion — and actually trust it: a different model reviews your code, plans, and research, and a fresh independent verifier subagent — never the session that wrote the work — judges every finding (Agreed/Disputed/Nuanced/Unverifiable, plus False Positive/Uncited from the citation script) before you act, catching hallucinated citations. Skills: setup, review, adversarial, rescue, verify, research, status, result, cancel, transfer. Task delegation (rescue) wraps your verbatim request in adaptive, preview-approved prompt blocks. Transfer hands the whole session off to a resumable Codex thread (v1.0.5+). Prompt-running skills accept --model/--effort via config.toml, also passed at run time when a project's own .codex/config.toml would override them.

Rubber duck tutor that keeps you engaged across the whole AI-coding lifecycle — before you ask AI to build (/duck-prebuild), once code is written and before you ship (/duck-verify, /duck-review), and when orienting to unfamiliar code (/duck-orient), plus /duck for auto-detect. /coach is its teaching sibling, manual-invocation only: /coach <topic> explains and drills a concept, /coach <file> or a bare /coach right after generating code dissects it section by section (what/why-this-way/where-it-breaks), and /coach alone surfaces an unresolved gap from a past duck session and teaches it — resolved only once you pass the exercise, not by saying you understand. Ship-point hooks triage what you just pushed against six risk categories and target the riskiest change you didn't actually discuss, fall back to retrieving an unresolved gap from a past session, or demote to a non-blocking scoreboard after three ignored confrontations in a row. Confrontation telemetry (fired/answered/ignored) is queryable from /duck-orient. Doesn't overlap /code-review or /grilling — duck only checks whether you understand, never whether the code or plan is good, and never teaches — that's coach's job.

Visualize Claude Code plugins, git diffs, and markdown docs as HTML or markdown reports with diagrams. On a capable account, HTML reports publish as claude.ai Artifacts (--local writes a local file instead). Skills: plugin-visual (plugin audit with security and architecture), diff-visual (catch up on a diff before review, with a quiz), doc-visual (diagrams per section), fact-check (verify claims against code and git history), report-manager (list, open, delete, search, refine). Reports take --format md and --lang.

Replaces Claude Code's built-in worktree — aligns with native git worktree where CC diverges (HEAD base, origin/* auto-tracking) and adds layers native lacks: .worktreeinclude/.worktreelink for gitignored files with a /worktree-setup skill that scans and builds them, upstream-aware removal guard, idempotent re-entry.
