Marketplace ${OFFICIAL_MARKETPLACE} exists with an unexpecte

Error message

Marketplace ${OFFICIAL_MARKETPLACE} exists with an unexpected source; refusing to replace it

What it means

`ensureOfficialMarketplace()` only adds the official marketplace when it is absent; if a marketplace named `compound-engineering-plugin` already exists but points at something other than a git clone of the official repository, the function refuses to overwrite it and throws this error instead of silently replacing a user's configuration.

Solutions

1. Run `codex plugin marketplace list --json` and inspect the source of `compound-engineering-plugin`
2. If it is unwanted, remove it with `codex plugin marketplace remove compound-engineering-plugin`, then retry `codex:dev -- remote`
3. If it points at a fork but you intend the official one, remove and re-add the official marketplace
4. If it is intentional (e.g. your own fork), keep local mode instead of switching to remote

Example fix

// before: fork marketplace under the official name
await runCodex(context, runner, ["plugin", "marketplace", "add", "me/plugin"])
await switchToRemote(context, runner) // throws
// after: official marketplace
await runCodex(context, runner, ["plugin", "marketplace", "remove", "compound-engineering-plugin"])
await switchToRemote(context, runner)

const marketplaces = JSON.parse((await runner.run("codex", ["plugin", "marketplace", "list", "--json"])).stdout)
const existing = marketplaces.find((m: { name: string }) => m.name === "compound-engineering-plugin")
if (existing && !JSON.stringify(existing).includes("EveryInc/compound-engineering-plugin")) {
  throw new Error("Official marketplace name occupied by a non-official source; resolve manually")
}

function isOfficialMarketplaceSource(m?: { marketplaceSource?: { sourceType?: string; source?: string } }): boolean {
  return m?.marketplaceSource?.sourceType === "git" &&
    m.marketplaceSource.source?.includes("EveryInc/compound-engineering-plugin") === true
}

try {
  await switchToRemote(context, runner)
} catch (error) {
  if (String(error).includes("unexpected source")) {
    console.error("Resolve the marketplace named compound-engineering-plugin manually before switching to remote")
  } else throw error
}

When it happens

Trigger: Calling `switchToRemote(context, runner)` when `codex plugin marketplace list --json` reports a marketplace named `compound-engineering-plugin` whose `marketplaceSource` is not `git` type or whose URL does not normalize to `https://github.com/EveryInc/compound-engineering-plugin`.

Common situations: The user previously added the marketplace from a local path (`sourceType: "path"`) or a fork's URL; the marketplace was installed from a different clone URL (SSH vs HTTPS counts only if normalization differs, but a fork does trigger this); leftover state from testing a custom marketplace under the same name.
