adonis0123 Bundle

Build or extend a persistent macOS local web surface when the request includes a stable *.localhost URL, an existing loopback daemon/gateway, login startup, or a thin .app launcher that opens or wakes a persistent local HTTP surface. Once triggered, it can add file-backed CRUD or local/public content projections without changing public publishing. Covers domain ownership, exact Host routing, explicit access/threat boundaries, safe mutations, launchd lifecycle, TDD, curl checks, and proportional browser QA. Do not use for public or remote URL launchers, public hosting, production deployment, ordinary frontend/CRUD work on an existing dev server, merely opening or interacting with an existing URL, website audits, or native apps with no local HTTP surface.

adonis0123 Bundle

Set up or migrate code-inspector-plugin across modern frontend frameworks. Use when you need click-to-source IDE navigation, hotkey customization, or inspector troubleshooting.

artsmc-claude-dev-agents Bundle

Use when Mark reports a bug by pasting a raw artifact with little or no prose — a stack trace, an HTTP request/response trace (URL + method + status like 500/403/404/502), a console/React/Prisma error, a ChunkLoadError, a shell error, or a screenshot of a visual defect — or when he says things like 'still failing', 'clicking X does nothing', 'no inline editor on the rendered page', 'do we have local postgres/pgvector?', or 'identify the true error'. This is the front-to-back debugging procedure — extract the trigger and reproduction from terse input, probe whether the underlying plumbing even exists, localize by contrasting known-good vs broken, and drive to a durable root cause rather than a workaround. Reach for this BEFORE proposing any fix.

Use when: a backend feature has been implemented and needs a security pass before PR review or merge. Trigger phrases: "check security", "security review backend", "security audit", "security check after implementation". Skip when task is purely frontend styling, config-only change, or documentation update with no logic. SCOPE: always review only the files changed in the current feature/PR.

Use when: a backend feature has been implemented and needs a performance pass before PR review or merge. Trigger phrases: "check performance", "performance review", "optimize backend", "review queries", "N+1 check". Skip when task is purely frontend, config change, or documentation update. SCOPE: always review only the files changed in the current feature/PR.

Use after any frontend/UI change, when user says verify UI, check the page, or does it render. Supersedes generic verify flows for rendered UI. Not for backend-only changes (verification-protocol test/lint/build covers those).
