Marketplace foundation: Deno-native JSR-URL plugin add (dx scaffolder protocol)

[rickylabs]

Marketplace foundation — Deno-native JSR-URL plugin add (dx scaffolder protocol)

Why (motivation / evidence)

Run-2 fresh-user eye-tests of all four published tutorials on jsr:@netscript/cli@0.0.1-alpha.12
found 0 of 4 completable. Every tutorial walls at its first official-plugin step:

Unsupported plugin kind … Supported kinds: api (exit 246)

Grounding (origin/main @ alpha.12) showed the published netscript plugin add <official-kind> path
does not exist for a real userland install. Official kinds (auth/workers/sagas/triggers/
streams) are registered only when the CLI discovers a NetScript monorepo checkout above the
project (add-plugin.ts:88-92 → resolveOfficialPluginSourceRoot → official-plugin-source.ts
requires packages/cli/bin/netscript.ts + plugins/*/scaffold.plugin.json). A jsr:@netscript/cli
userland install has no such checkout, so DEFAULT_PLUGIN_KIND_PROVIDERS ships only ['api'] and
every official kind is rejected. The scaffold.runtime e2e "passes" because it scaffolds inside the
monorepo, so the walk-up finds the real checkout — the true userland-JSR install path is untested
and unbuilt. (Supersedes the false "prod/JSR plugin add is already correct, thin stubs" assumption.)

What — the design

plugin add becomes a Deno-native, JSR-URL-scheme installer that is identical for first-party and
third-party plugins, and is the foundation of the NetScript marketplace.

Resolution (kind → JSR URL):

• Bare name → NetScript-scoped JSR package, e.g. netscript plugin add workers → jsr:@netscript/…workers.
  (Lock the exact convention in PLAN — published names are currently @netscript/plugin-<kind>; decide
  whether workers maps to @netscript/plugin-workers or we adopt @netscript/<kind>.)
• Scoped name → that JSR package as-is, e.g. netscript plugin add @acme/cool-plugin → jsr:@acme/cool-plugin.

Install pipeline (identical for native + external):

1. Validate the URL is a real JSR package (JSR registry/meta API via fetch; deno info/deno add
   semantics).
2. Validate it is a real NetScript plugin — the package must satisfy a published plugin protocol
   (exported manifest / declared scaffolder bin export). Define this contract.
3. External-package confirmation — for non-netscript-native packages, extract JSR metadata
   (name, version, author, description, links) and ask the user to confirm it's the intended package.
   Skippable with --skip-confirmation and --ci.
4. Run the plugin's own scaffolder via deno x / dx jsr:… — the plugin itself emits the
   scaffold artifacts it needs (e.g. auth → database/auth.prisma + auth-api service + /api/v1/auth/*
   routes; sagas/streams → runtime resource). No CLI-embedded templates, no static descriptors — the
   plugin owns its scaffolding. (This makes ANY third-party plugin installable the same way.)
5. Integrity + verification — verify the produced output (expected artifacts / checksums) and run
   any declared post-install scripts from the plugin manifest.

Maintainer ↔ prod symmetry:

• Maintainer mode defaults to --local-path (local plugin source/bin), accepts --jsr-url to
  exercise the JSR path.
• Prod CLI defaults to JSR, accepts --local-path to extend a project with locally-built plugins.

Enterprise-grade / Deno-native requirements (to harden in PLAN)

• Permission model for running an external plugin's scaffolder binary — do NOT blanket -A; scope
  Deno permissions (e.g. --allow-write=<projectRoot> and minimal read/net) and rely on the step-3
  confirmation gate for untrusted packages. This is the key security surface.
• Plugin protocol/manifest contract — the published, versioned shape that makes a JSR package "a
  valid NetScript plugin" (scaffolder bin export, declared artifacts, post-scripts, peer/runtime deps).
• Integrity — verify scaffolder output is what the manifest promised before declaring success;
  fail closed.
• Runtime vs scaffold split — userland depends on the plugin's runtime off JSR (thin import, no
  source copy / no source leak into userland); scaffolding is produced by the dx scaffolder run.
• e2e-cli-prod must exercise a TRUE userland install (outside any monorepo checkout) of at least
  one official kind, so this entire class can never regress (the current e2e blind spot).

Scope / blast radius

• packages/cli — new resolver + install pipeline + permission/confirmation/integrity layers; flag
  surface (--jsr-url, --local-path, --skip-confirmation, --ci); kind→URL convention.
• The five @netscript/plugin-* packages — each must ship a dx-runnable scaffolder bin + manifest
  (framework-source change → WSL Codex per doctrine).
• e2e-cli-prod — add true-userland official-plugin install coverage.

Relationships

• Supersedes fix(triggers): reject defer trigger actions instead of silent no-op (S2) #67 (dynamic plugin→package registry) — the "registry" becomes JSR + the netscript-scope
  convention + the plugin protocol.
• Unblocks fix(cli): JSR-safe bundled-asset embedding — prod CLI scaffold usable from JSR (alpha.5) #135 — all four tutorials wall on this; they become completable once it lands.
• Feeds fix(cli): prod-scaffold config import-map + non-zero error exit + Windows path-sep (alpha-1) #144 — tutorial doc-truth alignment retargets to the new plugin add mechanism.

Process

Harness-gated: research → plan → PLAN-EVAL (OpenHands minimax-M3, separate session) → WSL Codex
daemon-attached implementation slices → adversarial review → IMPL-EVAL (OpenHands qwen3.7-max) →
merge → cut alpha.13 → re-run the 4 eye-tests. Then this becomes the spine the marketplace builds on.

Deep-Search Brief — Competing framework MARKETPLACE / PLUGIN-INSTALL systems (serves issue #167)

Engine: OpenHands + openrouter/google/gemini-3.5-flash (web-browsing research run).
Output: post the dossier as a structured comment (or sequential comments if long) on GitHub issue
#167 (rickylabs/netscript). Grow it incrementally — post Track findings as you complete them, do
not defer everything to one final comment. Do NOT commit anything to the repo / do not modify files;
this is web research only. Title the first comment MARKETPLACE DEEP-SEARCH DOSSIER (Gemini 3.5 Flash).

SKILL

• netscript-harness — this is a harness-gated research phase feeding a PLAN; respect the
  research-only boundary (no code, no commits).
• netscript-doctrine — package/plugin archetype + public-surface vocabulary, so findings map onto
  NetScript's plugin model.
• netscript-deno-toolchain — Deno/JSR install primitives (deno add, deno run jsr:, deno x),
  so you frame analogs against what NetScript can actually do natively.
• openhands-handoff — your own run/reporting contract.

What you are serving (ground truth — do NOT research NetScript itself; write FOR this design)

NetScript is a Deno-native, JSR-published meta-framework (plugin architecture over Hono + oRPC +
Fresh + .NET Aspire; first-party plugins: workers, sagas, triggers, streams, auth). Issue #167 defines
a new netscript plugin add install mechanism that is to become the foundation of the NetScript
marketplace. The proposed design:

1. plugin add <kind-or-spec> resolves a name to a JSR package URL — bare name → a NetScript-scoped
   JSR package; scoped name (@acme/x) → that JSR package as-is.
2. Validate the URL is a real JSR package.
3. Validate it is a real NetScript plugin (a published plugin protocol/manifest contract).
4. For EXTERNAL (third-party) packages, extract registry metadata and ask the user to confirm; skippable
   via --skip-confirmation / --ci.
5. Run the plugin's OWN scaffolder via deno x / deno run jsr:… — the plugin emits the scaffold
   artifacts it needs (DB schema, service, routes, infra wiring). The plugin owns its scaffolding; the
   CLI does not embed templates.
6. Integrity-verify the produced output + run declared post-install scripts.
   Symmetry: maintainer mode defaults to local plugin source (--local-path, accepts --jsr-url); prod
   CLI defaults to JSR (accepts --local-path). Runtime = thin JSR import (no source copy); scaffolding
   = the installer run.

Your job: study how the BEST competing ecosystems do registry-resolved plugin/extension install (and
especially install-time scaffolding/codegen), so the #167 plan is best-in-class, enterprise-grade,
secure, and Deno-native. Validate or challenge each step of the design above with real-world evidence.

Targets (verify each; add others you judge relevant — do not pad with irrelevant ones)

Closest analogs — registry-fetch-then-run-an-installer-that-scaffolds (PRIORITIZE these):

• Angular ng add (fetches an npm package, runs its schematic installer that mutates the
  project) and ng update (migration schematics). This is the single closest analog — study deeply.
• Astro astro add (resolves an integration, installs deps, edits astro.config with a
  confirmation diff prompt).
• Nuxt nuxi module add (module registry resolution + install + config wiring).
• Nx plugins + generators (nx add, nx generate — generators ARE scaffolders; plugin = package
  exposing generators/executors; local vs published plugin symmetry).
• Expo config plugins + npx expo install (version-aware install + build-time config mods).
• Vue CLI plugins / Angular schematics ecosystem, Capacitor plugins.

Framework/CMS plugin marketplaces (the user named these — cover all):

• Medusa (plugins / modules), Directus (extensions + Marketplace + sandboxed extensions),
  Strapi (Marketplace + plugin SDK + strapi generate), Gatsby (plugins + themes; install =
  npm + config in gatsby-config), Convex (components/ecosystem, npx convex codegen, how
  components are added and what the manifest/contract looks like).

Other RELEVANT (pick the ones with genuinely transferable mechanics):

• Backstage (plugin architecture, app integration), Payload, Sanity (plugins + sanity install), Supabase (CLI + extensions), Shopify (App Store + Shopify CLI + Hydrogen),
  WordPress (plugin directory + trust/review), VS Code Extension Marketplace (manifest
  package.json contributes, publisher verification, signing), Storybook addons (storybook add
  runs a post-install that edits config), Vite/Rollup plugins, Homebrew taps, Raycast /
  Obsidian / Figma plugin stores (trust + review + sandbox models).

Dimensions to capture for EACH exemplar (cite URL + the specific mechanism — no vague claims)

1. Install command & resolution — exact CLI shape; how a short name maps to a registry package;
   official/first-party vs scoped/third-party namespacing; default registry + overrides.
2. Install-time scaffolding / codegen — does adding the plugin RUN code that writes files / edits
   config / adds migrations? How (schematic, generator, post-install, config-plugin)? Idempotency,
   conflict/merge handling, dry-run/preview, diff confirmation.
3. Plugin manifest / protocol contract — what declares a package as a valid plugin (manifest file,
   package.json field, exported symbol); capability/contribution declaration; the scaffolder/installer
   entrypoint convention; peer/framework-version constraints.
4. Trust, verification & security — how the system validates a package is genuine + safe; official
   vs community badges/curation; review/approval; publisher verification & signing/provenance; and
   crucially the permission/sandbox model when running third-party installer code (this is the Marketplace foundation: Deno-native JSR-URL plugin add (dx scaffolder protocol) #167
   security crux — capture how Directus sandboxes extensions, how VS Code/npm handle install scripts,
   how Deno's permission model could apply). Confirmation prompts for untrusted packages.
5. Versioning, lockfiles & upgrade/migration — version pinning, compatibility gates, update/
   migration flows (Angular ng update, Expo SDK upgrades).
6. Discovery / marketplace surface — the registry/marketplace website; search + metadata + ratings;
   how the CLI ties into the marketplace; first-party curation vs open submission.
7. First-party-dev vs published-install symmetry — how the framework develops its OWN plugins in a
   monorepo vs how end users install them from the registry (directly informs NetScript's maintainer/
   prod --local-path/--jsr-url symmetry).
8. Uninstall / removal / integrity — clean removal, leftover artifacts, verification of applied
   changes.

Synthesize (the deliverable — concrete, not a literature review)

1. Ranked pattern catalog — the transferable mechanics, each with the exemplar + URL + a one-line
   "how NetScript should apply it (or deliberately not)".
2. Validation of the Marketplace foundation: Deno-native JSR-URL plugin add (dx scaffolder protocol) #167 design — go step-by-step (1–6 above) and for each say: which exemplars do
   it this way, what they got right, what pitfalls to avoid, and any refinement to the NetScript step.
   Explicitly flag anything in the Marketplace foundation: Deno-native JSR-URL plugin add (dx scaffolder protocol) #167 design that NO mature ecosystem does (a yellow flag worth
   reconsidering) and anything best-in-class that Marketplace foundation: Deno-native JSR-URL plugin add (dx scaffolder protocol) #167 is MISSING.
3. Recommended plugin-manifest / protocol skeleton for NetScript (fields + the dx-scaffolder
   entrypoint convention), grounded in the closest analogs (ng add schematic collection, Nx generator
   schema, Astro integration shape, VS Code contributes manifest).
4. Security model recommendation — the trust + confirmation + permission-scoping model for running a
   third-party plugin's scaffolder, mapped onto Deno's permission flags (what to allow, what to deny by
   default, when to prompt). This is the highest-value section.
5. Marketplace surface roadmap — what the discovery/curation/verification surface should look like as
   it grows from "direct JSR install" to a full marketplace (so Marketplace foundation: Deno-native JSR-URL plugin add (dx scaffolder protocol) #167's foundation is forward-compatible).
6. Anti-patterns — concrete failure modes to avoid (e.g. arbitrary unsandboxed install scripts,
   namespace confusion / typosquatting, non-idempotent scaffolders, version-incompatible installs).

Constraints

• Cite EVERY exemplar with its URL and the specific mechanism — no generalities.
• Bias toward the registry-fetch → run-installer → scaffold analogs (ng add, astro add, nuxi, Nx,
  Expo config plugins, Storybook add) since they match Marketplace foundation: Deno-native JSR-URL plugin add (dx scaffolder protocol) #167 most directly.
• Keep findings actionable for a Deno/JSR-native CLI (note where an npm-ecosystem mechanic does/does
  not translate to deno add / deno run jsr: / Deno permissions).
• Honor repo voice doctrine: no "honest/honesty/honestly" or candor-announcing framing.
• Post incrementally to issue Marketplace foundation: Deno-native JSR-URL plugin add (dx scaffolder protocol) #167; do not commit to the repo.

Executive Summary & Core Insights

NetScript issue #167 defines a critical inflection point: moving from a collection of first-party packages to a rich, open, secure, and developer-friendly marketplace. The foundation of this marketplace is the netscript plugin add <kind-or-spec> install mechanism, which resolves packages directly from the Deno/JSR registry, validates their credentials and plugin protocol adherence, and then runs local scaffolder routines to integrate them.

This research dossier conducts an exhaustive analysis of the industry's best-practice plugin, integration, and schematic installation systems. Our primary goal is to validate, challenge, and refine NetScript’s proposed design using evidence from production ecosystems.

Core Key Takeaways for NetScript

1. The Scaffolding Divide (Imperative vs Declarative): Angular, Astro, and Nx use imperative AST mutation to alter configuration files and source code. This is powerful but highly fragile, prone to breakage across minor configuration shifts. VS Code, Convex, and Gatsby pivot toward declarative contributes/manifest matrices and sandboxed configuration schemas. NetScript, leverage Deno's native TypeScript capabilities! Instead of attempting complex regex or AST parsing of user files, the NetScript scaffolder should write standard, deterministic config/schema modules, and have the main program dynamically read/import them at boot time.
2. The "Deno Permission" Sandboxing Paradigm (Crux of Marketplace foundation: Deno-native JSR-URL plugin add (dx scaffolder protocol) #167): Node-based ecosystems (Angular, Astro, npm install-scripts) are notorious security hazards since third-party schematic code runs with absolute local root privileges. Under Deno, NetScript has the unprecedented capability to enforce rigorous permission boundaries directly on third-party plugin scaffolders. When triggering deno run jsr:... for a plugin scaffolder, NetScript MUST spawn it under strict --allow-read, --allow-write (restricted explicitly to the local workspace folder), --deny-net (unless specifically declared), and --deny-run policies.
3. Local/Remote Dev Symmetry: Nx and Angular prioritize first-party development vs published use-cases via "workspace generators." NetScript’s --local-path override matches Nx's local generator symlink paradigm, facilitating mono-repo co-development.

Targeted Exemplar Deep-Search (1 of 3): Major CLI Scaffolders

1. Angular Schematics (ng add & ng update)

• Primary Reference URL: Angular CLI Add | Angular Schematics Overview | Angular Update Guide
• Install Command & Resolution:
  ng add <package-spec>
  Resolves <package-spec> to an npm registry package. Bare names (e.g., @angular/material) resolve directly. Scoped names are respected.
• Install-time Scaffolding & Codegen:
  Adding an Angular package triggers @angular-devkit/schematics-cli. The package’s package.json designates a schematics collection file (usually collection.json). This file outlines named schematics. The ng-add schematic is automatically invoked. It performs AST (Abstract Syntax Tree) transformations on angular.json, main files, styles, and modules. It uses a virtual tree abstraction (Tree and Rule objects) to perform mutations before flushing them to the physical disk.
  Idempotency & Conflicts: The virtual Tree verifies file modifications. If conflicts occur (multiple files touched in overlapping lines), Angular halts and reverts the virtual tree, erroring gracefully unless files are forcibly overwritten.
  Dry Run: Fully supported via ng add <package-spec> --dry-run, outputting clean logs of created, modified, or deleted files without actual writes.
• Plugin Manifest / Protocol Contract:
  package.json contains a "schematics" key pointing to collection.json. The collection.json manifest strictly declares the schematic schema JSON mapping options to arguments, and the compiled JS factory entrypoint.
• Trust, Verification & Security:
  Angular schematics run with full Node.js privileges. No sandbox exists; malicious packages can run arbitrary filesystem sweeps or networking exfiltration inside custom factory scripts. Prompts are interactive (e.g., asking to choose a theme) but do not protect against compromised packages.
• Versioning, Lockfiles & Migrations:
  Tracked via standard npm install inside npm-shrinkwrap.json or package-lock.json. ng update reads the package's "ng-update" block pointing to migration schematics, automatically running codegen migrations (e.g., renaming import scopes, altering deprecated method calls) when transitioning versions.
• Symmetry of Local/First-party vs Published-install:
  Maintains exact symmetry. A developer can build and test local schematics using typescript directly. Local schematics are executed via schematics .:my-schematic, whereas published ones run via ng add.
• Uninstall Mechanics:
  Angular lacks automatic ng remove revert schematics. Uninstalling requires manual git revert or npm uninstall, leaving scaffolded code, templates, and styles stranded in the user’s codebase.

---

2. Astro (astro add)

• Primary Reference URL: Astro Add Command Reference | Astro Integration API
• Install Command & Resolution:
  astro add <integration-name-or-package>
  Resolves <integration-name> against both first-party alias mappings (e.g., tailwind maps to @astrojs/tailwind) and community integrations on npm. Scoped peer-packages are fully supported.
• Install-time Scaffolding & Codegen:
  1. Detects and prompts user to install dependencies using the local package manager (npm, pnpm, yarn, bun).
  2. Rewrites astro.config.mjs using AST parsers to import and wire up the integration inside the integrations: [...] array.
  3. Displays a clean, readable visual diff in the terminal showing exactly what changes are being made to astro.config.mjs.
     Idempotency & Conflicts: Handled at AST level; if compilation detects that the integration identifier is already imported and initialized, the modification is skipped.
     Dry Run: Supported via --yes or interactive verification CLI flows.
• Plugin Manifest / Protocol Contract:
  An Astro integration package must default-export (or name-export) a function returning an object adhering to the AstroIntegration TypeScript type (wrapping name and lifecycle hooks like astro:config:setup, astro:server:setup, and astro:build:start).
• Trust, Verification & Security:
  Executes with full shell permissions. It outputs the exact configuration adjustments and asks for permission before running: Astro will make the following changes... Continue? (Y/n). No VM sandbox is active.
• Symmetry of Local/First-party vs Published-install:
  Excellent parity. Developers can declare local plugins in astro.config.mjs via standard path-relative imports, or install them from npm, with no change in core runtime behavior.
• Uninstall Mechanics:
  No automatic astro remove removal schematics are provided; removal of configuration adjustments requires manual editing of astro.config.mjs.

3. Nuxt (nuxi module add)

• Primary Reference URL: Nuxi Module Add | Nuxt Modules Developer Guide
• Install Command & Resolution:
  nuxi module add <module-name>
  Resolves modules against Nuxt's Centralized Module Registry (https://api.nuxt.com/modules) and community scopes on npm.
• Install-time Scaffolding & Codegen:
  Installs the module package. Uses magicast (a Recast-powered AST utility for programmatically editing TS files) to inject the module into the modules array inside nuxt.config.ts. No custom runtime code is executed for folder configuration; Nuxt modules hook directly into Nuxt's runtime hooks at boot-time instead.
• Plugin Manifest / Protocol Contract:
  Modules are declared via defineNuxtModule from @nuxt/kit. Declares a meta property (declaring name, configKey, compatibility with Nuxt/Bridge versions), plus setup functions.
• Trust, Verification & Security:
  Modules are curated and categorized inside the Nuxt Registry (marked as official, community, or unverified). Installation execution is unsandboxed.
• Symmetry of Local/First-party vs Published-install:
  Perfect. Local modules are loaded in nuxt.config.ts via relative filesystem paths under the modules array.
• Uninstall Mechanics:
  No automated uninstall cli; user manually deletes the lines from nuxt.config.ts.

---

4. Nx Plugins and Generators (nx add, nx g)

• Primary Reference URL: Nx Add Command | Nx Plugin Generators
• Install Command & Resolution:
  nx add <plugin-package> or nx g <plugin-package>:<generator-name>
  Resolves against the public npm registry or local workspace reference directories. Prefers standard npm namespace structures.
• Install-time Scaffolding & Codegen:
  Nx utilizes a conceptual virtual file tree system via @nx/devkit. When running an imperative "generator" script, all file mutations (reads, writes, AST transforms) are executed inside an in-memory Tree object.
  Idempotency & Diff Confirmation: Nx supports standard --dry-run out of the box. Running dry run outputs a log of all modifications (created, modified, or deleted files) without altering the disk. If physical file contents overlap conflict-wise, a git-style merges-prompt or a clean overwrite-protection warning occurs.
• Plugin Manifest / Protocol Contract:
  A plugin contains a generators.json (or collection.json) mapping generator names to their schemas and execution scripts. Each generator must provide a descriptive schema.json declaring parameters with validation fields, and an entrypoint function with signature (tree: Tree, schema: SchemaOptions) => void | Promise<void | GeneratorCallback>.
• Trust, Verification & Security:
  Runs natively on local Node.js environment without VM sandboxes. Curation is mostly handled by public npm registry visibility and official plugin badges.
• Symmetry of Local/First-party vs Published-install:
  Excellent. Nx permits local "workspace generators" inside the workspace that run using local code, maintaining immediate symmetry between local plugin development and published plugins.

5. Expo Config Plugins & npx expo install

• Primary Reference URL: Expo Config Plugins Reference | Expo Install CLI
• Install Command & Resolution:
  npx expo install <package>
  Resolves against npm, but checks a centralized compatibility matrix file mapped to the project's current Expo SDK major version. It acts as an intelligent peer-dependency manager.
• Install-time Scaffolding & Codegen:
  Config plugins are JS functions that run during native platform compilation (npx expo prebuild). Instead of modifying physical native files permanently during installation (expo install), native config modifications are deferred and evaluated dynamically at build-time. The plugin reads app.json (the declarative configurations) and modulates target Android/iOS code templates programmatically during build compilation.
• Plugin Manifest / Protocol Contract:
  Config plugins are declared inside app.json (or app.config.js) under the "plugins" array. The module must export a function matching the signature ConfigPlugin<T> = (config: ExpoConfig, props: T) => ExpoConfig.
• Trust, Verification & Security:
  Permissions are elevated during prebuild. Interactive prompts do not sandbox execution. However, because scaffolding modifications are evaluated at build-time dynamically inside a controlled config pipeline rather than immediately writing static native code to disk upon installation, the user can easily toggle the plugin off inside app.json.

6. CMS / Framework Marketplaces

A. Medusa Plugins and Commerce Modules

• Primary Reference URL: Medusa Commerce Modules | Medusa Extension SDK
• Install Command & Resolution: Installed standard-npm-wise (npm install <package>). Registry resolution is standard npm.
• Install-time Scaffolding / Codegen: No immediate post-install CLI scaffolding. Everything is structured via the Commerce Modules paradigm. Databases are updated programmatically when running the centralized migration CLI medusa db:migrate.
• Plugin Manifest / Protocol Contract: Explicit module declarations are registered inside medusa-config.js with structured configuration blocks mapping services and loaders.

B. Directus Extensions and Marketplace

• Primary Reference URL: Directus Extension Sandboxing | Directus Marketplace Overview
• Install Command & Resolution: Installed directly inside Directus' central Admin Dashboard App Interface or via npm install <extension-package>.
• Install-time Scaffolding / Codegen: The Admin Console downloads the extension tarball to the extensions/ directory. If migrations or schema configurations exist, Directus executes them automatically during server startup.
• Plugin Manifest / Protocol Contract: Extensions present a specific package.json descriptor carrying directus-specific metadata fields declaring their kind (e.g., interface, display, endpoint, hook, operation).
• Trust, Verification & Security (The Sandbox Exemplar):
  Directus provides a highly relevant sandbox model. Extensions are executed inside a sandboxed environment (isolated-vm or standard restrictive processes in cloud instances) with strict privilege restrictions. For the Directus Self-Hosted Marketplace, packages must pass a strict security review and automated analysis before being cleared for the community registry. Unverified, direct-file extensions can be loaded locally but flag explicit security warnings to administrators.

C. Strapi Marketplace

• Primary Reference URL: Strapi Market | Strapi Generate CLI
• Install Command & Resolution: Installed via npm install or resolved via the marketplace dashboard UI.
• codegen / Scaffolding: Uses manual scaffolding or pre-built local schemas. Generates local boilerplate files via the standalone interactive command strapi generate.
• Manifest & Safety: Uses custom plugins configured inside config/plugins.js. No VM sandboxing; relies on manual code audits and public verification of publisher metadata on the Strapi Market portal.

D. Gatsby Recipes & Convex Components

• Primary Reference URLs: Gatsby Recipes | Convex Backend Components
• Gatsby Recipes Mechanic: The most declarative installer ever built. Instead of letting arbitrary JS run during install to rewrite user files, Gatsby Recipes are written in MDX with declarative JSX components (like <NPMPackage name="gatsby-source-contentful" />, <GatsbyPlugin name="gatsby-source-contentful" />, <File write="..." />). The Gatsby CLI parses the recipe, resolves what will occur, presents a unified visual diff, and safely executes those declarative declarations.
• Convex Components Mechanic: Under Convex, components are independent directory scopes registered under a centralized backend. They are declared via convex.config.json with clear interfaces. Scaffolding is kept local, and actual wiring is evaluated through type-safe schema compilers without mutating the developer's raw source file imports.

8-Dimension Deep-Dive Analysis across Exemplars

This section consolidates how elite frameworks resolve the 8 architectural dimensions requested.

Dimension 1: Install Command & Resolution

• Angular CLI (ng add): Resolves bare names via a local JSON fallback map first (e.g. @angular/pwa -> @angular/pwa npm script), otherwise queries npm. Scope names are resolved directly on the npm registry.
• Astro CLI (astro add): Uses strict mapping aliases (like tailwind -> @astrojs/tailwind) to maintain a clean public-surface lexicon.
• Nx (nx add): Directly delegates the install command to the detected package manager (npm, yarn, pnpm, bun) then invokes the package's initial generator.
• Expo CLI (npx expo install): Fetches SDK-specific metadata configuration maps (https://expo.dev/--/api/v2/versions) to pinpoint compatible major/minor coordinates instead of querying npm blindly.
• Nuxt Module Add (nuxi module add): Maps lazy package identifiers against the Nuxt API, preventing version clashes.
• NetScript Mapping Alignment: The proposed #167 style maps bare names to a NetScript-scoped JSR package (@netscript/<name>) and scoped names (@acme/x) directly as-is on JSR. This aligns perfectly with Astro and Angular aliases while staying JSR native.

Dimension 2: Install-Time Scaffolding / Codegen

• Angular (Schematics) & Nx (Generators): Imperative JS/TS code that mutates actual files. They read and modify JS/TS TS-AST nodes, ensuring structurally sound edits. But AST mutation is expensive to write and fragile if user files deviate from expectations.
• Astro & Nuxt: Configuration-focused AST rewrites (targeting astro.config.mjs or nuxt.config.ts).
• Gatsby (Recipes): Fully declarative! Parses MDX recipe instructions, shows side-effects in dry-run, and executes cleanly.
• Convex & Expo: Defers actual file rewrites by maintaining runtime imports or dynamic build-time compilation hook structures over a standard app.json.
• NetScript Alignment: NetScript’s proposed design has the plugin own its scaffolding via deno x / deno run jsr:.... The CLI acts as the orchestrator, not the template host. This is a very clean separation of concerns!

Dimension 3: Plugin Manifest / Protocol Contract

• VS Code Extensions (package.json): Leverages a static contributes manifest representing absolute declarations of commands, shortcuts, and themes. The host reads this without executing any third-party code.
• Angular & Astro: Specify an entrypoint structure. For Astro, it's an object with hook definitions (astro:config:setup, etc.). For Angular, it's collection.json metadata defining schematic rules.
• Convex Components (convex.config.json): Declaratively registers dependency hooks and boundaries, allowing compile-time isolation.
• NetScript Alignment: NetScript should define a formal plugin manifest contract (such as netscript-plugin.json or as exported metadata from mod.ts) declaring supported triggers, hooks, database migrations, and scaffolding entrypoints.

Dimension 4: Trust, Verification & Security

• Directus Extension Sandbox: Directus runs extensions inside restricted JavaScript environments (isolated-vm or node sub-processes with limited capability scopes) to avoid unprivileged database sweeps or networking exfiltration.
• VS Code & npm: Rely heavily on publisher verification & signature validation (e.g., Sigstore provenance, verified publisher badges on VS Code marketplace).
• The Security Gap: Almost all npm tools (Angular, Astro, storybook) run installers unsandboxed. NetScript can change this paradigm entirely by taking advantage of Deno's native flags (--allow-read=<path>, --allow-write=<path>, --deny-net, etc.).

Dimension 5: Versioning, Lockfiles & Upgrade/Migration

• Angular (ng update): Reads the "ng-update" property inside package.json to obtain migration schematics. Migrations are run on major upgrades to auto-refactor deprecated APIs.
• Expo CLI: Version pinning is governed by an automated SDK version list. The CLI prevents mixing incompatible core libraries.
• NetScript Alignment: Native Deno lock files (deno.lock) and JSR semantic versioning (which enforces strictly reproducible builds and version constraints) make this extremely lightweight for NetScript.

Dimension 6: Discovery / Marketplace Surface

• Strapi Market & VS Code: Feature official vs community badges, verified publisher checks, download counts, and ratings. Curation is done through strict manual submissions.
• Nuxt & Astro Registries: Read metadata directly from automated GitHub workflows or static registries, providing an open, lightweight discovery mechanism.

Dimension 7: First-Party Dev vs Published-Install Symmetry (Local Symmetry)

• Nx Plugins: Local generators are placed under a local directory (e.g. tools/generators) and invoked exactly like published packages.
• NetScript Alignment: NetScript's proposal coordinates this symmetry cleanly: --local-path is used by maintainers to develop and scaffold plugins directly from local development folders, while production users download directly from JSR.

Dimension 8: Uninstall / Removal / Integrity

• Angular: Lacks automatic removal; uninstalling leaves scaffolded code orphaned in the workspace.
• Astro & Nuxt: Manually deleting config lines is the standard path.
• Gatsby Recipes: Keeps a strict internal state log, allowing clean revert/uninstall routines of all declarative edits.
• NetScript Alignment: If NetScript plugin scaffolding writes artifacts to dedicated, deterministic files or directories, removal is as simple as deleting those directories, preventing scattered codebase drift.

Synthesis & Architectural Recommendations for NetScript

This chapter provides actionable, concrete designs to refine and guarantee the success of NetScript's issue #167 marketplace initiative.

1. Ranked Pattern Catalog for NetScript

The following table ranks the most valuable patterns from our research, along with specific implementation recommendations:

Rank	Pattern	Source Ecosystem	Practical NetScript Application
1	Deno Permission-Scoped Scaffolder Execution	Native Deno Security	Apply: Run the third-party installer using --allow-read and limit --allow-write strictly to the local subdirectories (like ./plugins/).
2	Aesthetic AST Difference Preview	Astro Add CLI	Apply: Show the diff representation of any auto-injected configuration exports to the developer and prompt before writing files.
3	Interactive Dry-Run Mode	Nx Generators	Apply: Introduce --dry-run to CLI scaffolder calls, allowing the program to execute file generation purely in memory.
4	Static Capabilities Registry	VS Code Manifest	Apply: For optimal performance, parse the JSON metadata fields of the plugin without initiating a runtime module boot.
5	Declarative Scaffold Recipes	Gatsby Recipes	Apply: Instead of allowing execution of arbitrary JS, prompt the scaffolder to emit a declarative JSON manifest mapping tables, files, and routes to be created.
6	Central Compatibility Maps	Expo SDK / Nuxt API	Avoid: Do not hardcode version maps inside NetScript CLI; rely on JSR's built-in semantic version constraints.

2. Validation & Critique of the Proposed NetScript #167 Design

Below, we analyze each step of NetScript's proposed 6-step plugin add protocol:

• Step 1: Bare name/Scoped name JSR package URL resolution
  • Validation: Excellent. Emulates Angular and Astro mappings.
  • Refinement: Guard against typosquatting. Ensure bare name resolution defaults to verified @netscript scopes only, prompting with warnings if resolving to unverified third-party scopes.
• Step 2: Validate the URL is a real JSR package
  • Validation: Correct. Uses a fast JSR metadata check (https://jsr.io/@scope/name/meta.json).
• Step 3: Validate the URL is a genuine NetScript plugin
  • Validation: Critical. Ensure validation can be performed statically (either by loading the JSR package's raw manifest JSON or querying JSR metadata) prior to executing the package's code.
• Step 4: Prompt third-party confirmation & --skip-confirmation
  • Validation: Standard. Matches Astro and Angular CLI behaviors.
• Step 5: Run the plugin's own scaffolder via deno run jsr:...
  • Validation: Ultra-flexible strategy. Devolving scaffolding files/artifacts to the plugin itself is a highly elegant, decoupled solution.
  • Safety Red Flags: Running arbitrary third-party code via deno run jsr: is an immediate vector for compromise unless wrapped in a restricted sandbox! (See our security recommendations below).
• Step 6: Integrity verification of produced outputs & Maintainer local symmetry
  • Validation: Strong. Local path development (--local-path) mirrors Nx workspace generator symmetry perfectly, enabling seamless first-party developer cycles vs published JSR production use.

Missing Best-in-Class Features:

1. Strict Idempotency Assurance: NetScript must mandate that the plugin's scaffolding script can run repeatedly without corrupting existing code files or producing duplicate lines.
2. Visual Configuration Diff Preview: Astro's primary DX value-add is displaying a clear visual diff of modified configurations prior to physical execution. NetScript should log the file writes/updates to terminal stdout before finalizing them.

3. Recommended Plugin-Manifest & Protocol Specification

To define a secure, highly predictable, and developer-friendly installation routine, we propose the following schema definition.

Static Manifest Contract: netscript-plugin.json

Every NetScript marketplace plugin must publish a netscript-plugin.json manifest at its root. This allows NetScript CLI to validate and read metadata statically without executing any JS code:

{
  "$schema": "https://netscript.dev/schemas/plugin.v1.json",
  "name": "@netscript/cron",
  "version": "1.4.2",
  "displayName": "Enterprise Cron Scheduler",
  "description": "Distributed cron scheduling engine with built-in telemetry.",
  "peerDependencies": {
    "netscript": "^2.1.0"
  },
  "capabilities": {
    "hasDatabaseMigrations": true,
    "hasRoutes": true,
    "hasBackgroundWorkers": true
  },
  "scaffolder": {
    "entrypoint": "cli-scaffold.ts",
    "requiredPermissions": {
      "net": false,
      "read": ["./"],
      "write": ["./plugins/cron/", "./db/migrations/"]
    }
  }
}

The dx-scaffolder Entrypoint Convention

The plugin's scaffolding entrypoint (cli-scaffold.ts) should export a default function adhering to a standard protocol interface:

// Proposed protocol structure
export interface ScaffolderContext {
  workspaceRoot: string;
  options: Record<string, unknown>;
  dryRun: boolean;
  logger: {
    log: (msg: string) => void;
    warn: (msg: string) => void;
  };
}

export interface ScaffoldResult {
  status: "success" | "failed";
  createdFiles: string[];
  modifiedFiles: string[];
  databaseMigrationsAdded: boolean;
}

export default async function scaffold(ctx: ScaffolderContext): Promise<ScaffoldResult> {
  // Scaffolder logic goes here...
}

4. Deno-Native Security & Sandboxing Architecture (The Core Solution)

Node.js ecosystems suffer from lack of sandboxing during installation. Under Deno, NetScript has a powerful security layer. By exploiting Deno's native fine-grained permissions, NetScript can isolate third-party installers completely:

1. Spawn the Scaffolder Process using Limited Flags:
   When issuing deno run jsr:... to run the plugin's internal cli-scaffold.ts, spawn the command as a subprocess using strict, minimal capabilities:

   deno run --allow-read --allow-write="./plugins/, ./db/migrations/" --deny-net --deny-run jsr:@scope/plugin/cli-scaffold

2. Enforced Permission Sandbox Matrix:
   • --allow-read: Grant access ONLY to the project's root folder (./). This prevents the scaffolder from harvesting system config directory variables (like ~/.ssh or ~/.aws/).
   • --allow-write: Restrict writes exclusively to the directory designated for that plugin (e.g., ./plugins/<plugin-name>/) and the project's migration repository. Prevent arbitrary modifications to vital framework code.
   • --deny-net (Default): Deny outbound internet connections. If a plugin absolutely requires network access during installation (e.g., pulling a remote asset/schema), the user must see an explicit prompt and grant permission, avoiding quiet exfiltration of secrets.
   • --deny-run: Absolute denial of subprocess execution. The installer cannot spawn hidden shell programs or install system-level global binaries.

Security Confirmation UX Flow (Mock):

⚠️  [NetScript Security Sandbox] Installing third-party plugin "@acme/analytics"...
This plugin requests the following scaffold permissions:
  ✓ Write access to: ./plugins/analytics/
  ✓ Read access to: ./
  ✕ Network requested: YES (Targeting: api.analytics.acme.com)
  ✕ System execution: NO (Blocked)

Do you trust "@acme/analytics" and want to grant network access? [y/N]

5. Forward-Compatible Marketplace Surface Roadmap

NetScript can grow incrementally from JSR resolution to a mature, first-class enterprise marketplace:

1. Phase 1: JSR-Native Manifest Resolution (Immediate)
   Resolves purely against stable JSR URL paths. The CLI parses static metadata manifests (netscript-plugin.json) and runs sandboxed Deno install pipelines.
2. Phase 2: Verified Scopes & Signature Curation (Short-term)
   NetScript establishes a list of officially verified scopes (@netscript, @netscript-community). Installing packages from outside these scopes triggers explicit CLI safety prompts.
3. Phase 3: Centralized Indexing & Discovery Portal (Long-term)
   Build market.netscript.dev as a lightweight metadata index (harvesting JSR search API endpoints and scoring ratings/tags). The CLI implements search overlays (netscript plugin search <term>).

---

6. Anti-Patterns to Avoid

• AP-1: Unsandboxed Scaffolding Runs: Permitting arbitrary JS/TS scaffolder code to execute with root machine privileges.
• AP-2: Non-Idempotent Code Injections: Repeatedly adding line entries to config modules, leading to corrupted, un-parsable configurations.
• AP-3: Scope Hijacking / Typosquatting: Letting bare names resolve to obscure unverified namespaces (e.g. auth mapping to @unverified/auth instead of @netscript/auth).
• AP-4: Fragile Source AST Mutations: Modifying user-written controllers or routes. Favor writing clean, self-contained plugin modules and registering them statically inside local plugin manifests.

🔒 Architecture locked — full unification of the plugin command surface (2026-06-29)

This issue's "Deno-native plugin add" foundation is being delivered as a full unification of the
entire netscript plugin <verb> <kind> machinery (PR #172, task #157). Locking the decisions here so
they are settled before implementation.

Decision 1 — ownership & extension model

@netscript/plugin + @netscript/cli own the command logic and rule the shape — opinionated,
strong single-target defaults. Core is never aware of any specific plugin. The plugin package is
the "NetScript adapter" / connector: it plugs plugin-core's implementation into the ecosystem
(services, setup, scaffold, commands) by supplying a typed contract object + seams.

Mechanism = composition + contract, modeled on Vite's plugin architecture (proven composition),
made more restrictive because NetScript is single-target, not multi-framework → strong defaults.
A plugin returns a typed NetScriptPlugin object from a factory (createPluginAdapter); core owns
the pipeline and calls into it. No cross-package implementation inheritance — doctrine 03
(L162-175, Bloch Item 18) forbids a plugins/* adapter extends-ing a base from @netscript/plugin;
extension across packages happens through interfaces + registration, which is exactly the
contract+seams shape.

Decision 2 — command taxonomy

MANDATORY (every plugin has them; shared logic lives in core, parameterized by plugin-supplied
typed seams — full lifecycle, day one):

• install (rename of add) — seams: dep specifier · starter resource set · NetScript-config
  params · Prisma contract path · wiring entrypoint spec
• doctor — seams: health endpoint (sensible default) · required config keys · extra checks
• info — seams: capabilities · version source (defaults to manifest)
• update — core defaults (re-resolve dep + re-sync wiring/config)
• remove — core defaults (reverse install)

OPTIONAL (per-plugin specifics; core defines the contract/shape like an oRPC contract, plugin
implements): add <resource> (was add-* → add job/add task/…), generate <resource>
(was generate-* → generate registry), plus list/run/logs/… as contract-shaped optionals.

Decision 3 — naming (breaking, acceptable pre-1.0)

Full rename + namespace: netscript plugin install <kind>, netscript <kind> add <resource>,
netscript <kind> generate <resource>.

Decision 4 — one item generator

A single type-checked ItemScaffolder<TInput> (type-checked stub source-of-truth + typed identifier
substitution — no string concatenation, no .template files) drives BOTH install (starter set)
and add <resource> (user id). This kills the three current overlapping mechanisms
(renderPlugin() full-source copy, the thin-scaffold pass, and the src/scaffolding/ string
generator) and the three forked, base-less item-scaffolder contracts.

What stays correct (kept)

CLI host-side config wiring (appsettings / netscript.config.ts / deno.json / register-plugins /
service-context) and copyPluginSchemasToRootDb are correct and unchanged. Only the
renderPlugin() full-source branch is deleted. A plugin is a dependency, never stringified into
userland.

Bar = definition of done + output quality. Slices, gates, and the full plan are in PR #172.
