Cross-vendor second-opinion code review client commands (/second-opinion:start, /second-opinion:models). Does not auto-register an MCP server on install; the external mcp-second-opinion server is opt-in - register it with `claude mcp add second-opinion --transport http --url http://127.0.0.1:8080/mcp` once it is running.

Claude Power Pack cross-cutting help/meta plus utilities: /cpp:help maps every CPP command family; /cpp:dockers container status, /cpp:happy-check, /cpp:load-best-practices (bundled 25K guide), /cpp:load-mcp-docs (folded from top-level commands, #582). The legacy symlink installer is not distributed as a plugin.

Security scanning: quick/full/deep scans (gitleaks, git history, pip-audit), finding explanations, and risk-graded permission audits (/security:*).

CLAUDE.md management: lint for missing CI/CD, Docker, and troubleshooting directives.

GitHub issue management: create, list, view, update, and close issues from Claude Code (/github:issue-*).

Codex CLI orchestration: read-only delegation (/codex:ask), one-shot exec with JSONL monitoring, full issue lifecycle delegation (/codex:auto), and readiness checks.

Self-improvement loops: post-run friction retro + codify, deployment retrospectives, and the fleet-wide friction-knowledge ledger (/self-improvement:*).

CI/CD automation: Makefile init/check, pipeline codegen (GitHub Actions or self-hosted Woodpecker), container generation, health checks, smoke tests, deploy verification, and tiered IaC scaffolding.

Documentation and diagrams: C4 architecture diagrams as GitHub-renderable Mermaid (/documentation:c4) and PowerPoint generation (/documentation:pptx).
