plugin-builder

Scaffold a new plugin inside an existing marketplace — the shipped dir skeleton, plugin.json, install.sh with the Git-Bash guard, settings.json, and CLAUDE.md; then register it in the catalog and in release-please packages with the catalog extra-files sync. Use when adding a plugin to a marketplace.

Audit a marketplace (or a single plugin) — run the shipping-hygiene sensor, structural checks (every catalog entry has a dir, every dir has a manifest, versions in sync), and the portability sweep. Reports findings and offers fixes. Use to validate a marketplace is healthy.

Generate the gated SessionStart install hook plus cloud-setup.sh and a "use skills directly" fallback so the marketplace is usable in Claude Code web/cloud sessions. Use to make a marketplace cloud-aware.

Scaffold a new Claude Code plugin-marketplace monorepo — catalog, repo-root tests/scripts/docs trees, CI workflows, release-please config, dev-setup, the hygiene sensor, and a root CLAUDE.md. Use when starting a fresh marketplace repository.

Run shellcheck -x over every shipped and dev shell script, flag bash-4/GNU-only constructs, verify env-bash shebangs, and check that each install.sh has the Git-Bash-on-Windows guard. Use to validate cross-platform portability (macOS bash 3.2 / BSD / Windows Git Bash).

Wire release-please with one package per plugin and the marketplace.json extra-files jsonpath sync, so plugin.json, the release tag, and the catalog entry can never drift. Use to set up or repair automated versioning + catalog sync.
