What it does

Install Start is an agent skill from foxted/rsc-boundary. Installs and wires the npm package @rsc-boundary/start into a TanStack Start app (dependencies, root route provider, optional explicit markers). Use when the user wants to add RSC Boundary to a TanStack Start / TanStack Router app, or set up server/client boundary devtools with TanStack.

Its SKILL.md is about 970 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with TanStack, npm, React and Next.js. The repository describes itself as: Tooling to visualize React Server Components vs Client Components boundaries in Next.js App Router. The licence is MIT.

When your agent uses it

  • The user wants to add RSC Boundary to a TanStack Start / TanStack Router app
  • Set up server/client boundary devtools with TanStack

Example prompts

  • “Use the install-start skill to install and wires the npm package @rsc-boundary/start into a TanStack Start app (dependencies, root route provider…”
  • “/install-start”

Requirements

  • Node.js

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Install the dependency
  2. Add the provider to the root route
  3. Behavior to set expectations
  4. Optional API (only if the user asks)
  5. Verify

What it can do on your machine

Read from SKILL.md and the folder at commit ad7aa8e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • pnpm
    • npm
    • yarn

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use pnpm, npm and yarn, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Install Start loads about 969 tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 324 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~76
When it runs · the whole SKILL.md, loaded when a task matches
~969

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Installs and wires the npm package @rsc-boundary/start into a TanStack Start app (dependencies, root route provider, optional explicit markers). Use when the user wants to add RSC Boundary to a TanStack Start / TanStack Router app, or set up server/client boundary devtools with TanStack.

Install RSC Boundary in a TanStack Start app

Package: @rsc-boundary/start on npm.

Prerequisites

  • @tanstack/react-start 1+
  • React 19+ and react-dom 19+ (peer dependencies)

If versions are older, say so and recommend upgrading before installing.

1. Install the dependency

Use the project's package manager:

bash
pnpm add @rsc-boundary/start
bash
npm install @rsc-boundary/start
bash
yarn add @rsc-boundary/start
Monorepo / local development

If the user is working inside this repository and consuming the package from the workspace, use the workspace protocol:

json
"@rsc-boundary/start": "workspace:*"

Ensure the packages are built (pnpm --filter @rsc-boundary/start build, which also builds core) before the app typechecks against dist/.

2. Add the provider to the root route

Edit the root route file (app/routes/__root.tsx).

  1. Import the provider:

    tsx
    import { RscBoundaryProvider } from "@rsc-boundary/start";
  2. Wrap <Outlet /> (or {children}) inside <body> with <RscBoundaryProvider>.

Minimal pattern:

tsx
import { RscBoundaryProvider } from "@rsc-boundary/start";
import { Outlet, createRootRoute } from "@tanstack/react-router";
import { Meta, Scripts } from "@tanstack/react-start";

export const Route = createRootRoute({
  component: RootComponent,
});

function RootComponent() {
  return (
    <html lang="en">
      <head>
        <Meta />
      </head>
      <body>
        <RscBoundaryProvider>
          <Outlet />
        </RscBoundaryProvider>
        <Scripts />
      </body>
    </html>
  );
}

Preserve existing structure: <ScrollRestoration />, <Scripts />, <Meta />, and any other layout UI stay as they are—only add the provider around the main content as appropriate.

3. Behavior to set expectations

  • Development: A small control (pill) appears in the bottom-left; toggling it highlights client vs server regions. No changes are required in individual route components.
  • Production: The provider is a no-op (children only). Devtools never mount in production builds.

4. Optional API (only if the user asks)

From @rsc-boundary/start the app can also use:

  • RscServerBoundaryMarker / SERVER_BOUNDARY_DATA_ATTR — explicit server region labels, useful when heuristic detection misses or mislabels a subtree
  • RscDevtoolsStart — advanced mounting without the provider wrapper
  • createRscBoundaryProvider — factory for custom wiring (re-exported from @rsc-boundary/core)

Prefer RscBoundaryProvider unless the user's setup requires splitting these.

Explicit marker example:

tsx
import { RscServerBoundaryMarker } from "@rsc-boundary/start";

// In a server-rendered component:
<RscServerBoundaryMarker label="HeroSection">
  <section>...</section>
</RscServerBoundaryMarker>

5. Verify

  • Run pnpm dev (or vinxi dev).
  • Open the app in the browser; confirm the RSC Boundary control appears and toggling highlights boundaries.
  • Navigate between routes; the MutationObserver should re-scan automatically.

Troubleshooting (brief)

  • Peer dependency warnings: Align react and react-dom to ^19.
  • Types / module not found: Ensure install completed and, for workspace usage, that packages are built.
  • Nothing in production: Expected; devtools are development-only.
  • Framework internals still visible in panel: Open an issue with the component name so it can be added to the startAdapter internals list.
