fix(init): stop agents from silently relinking a repository by seanperez29 · Pull Request #582 · clerk/cli

seanperez29 · 2026-10-26T14:37:32Z

Summary

In agent mode, clerk init --app <id> replaced an existing link to a different application without asking. Inside a Git repository the link is stored for the whole repository (by remote, else by its Git directory), so relinking one folder switched every project there to the new application. A monorepo with a web app linked to A could have its link switched to B by an agent setting up a second app. Human mode already asks (clerk link's "Re-link to …?"); agents didn't, since #212.

clerk init now stops instead, unless --relink is passed.

replacedLink(cwd, app) in link reports which link a new --app would replace and over what scope. Inside a repository that's the repository's link. Outside one, it's only a link stored for that exact folder; a folder whose parent is linked elsewhere gets a link of its own and isn't stopped.
The stop is a usage error naming the current application and the scope: /repo is linked to Web (app_A). Linking it to app_B switches every Clerk CLI command in /repo to app_B. Rerun with --relink to switch it, or pass --app app_A to keep the current link. With --json it is also printed as { "status": "input-required", "link": { "flag": "--relink", "question", "issue", "current", "requested", "scope" } }.
When it's checked: a --starter app before anything is written (the stop also offers --app <linked> to share the repository's application, or creating the app outside the repository), and a project init generates in a blank directory once it exists, before linking.
--relink is a usage error without --app.
The native-init E2E test, which asserted the old silent relink, now expects the stop and then a successful --relink run.

This is the first of two stacked PRs that move setup rules out of agent prompts and into the CLI. Next: #583 (JSON for iOS and macOS starters).

Validation

bun run format:check, lint, typecheck, and bun run test (4,963 pass).
Live, with real Git repositories, real Xcode, and a throwaway CLERK_CONFIG_DIR: a repository linked by Git directory, one linked by remote (run from a subfolder), and a non-Git parent link all behave as described.
E2E (test:e2e:op) not run locally; CI runs it.

🤖 Generated with Claude Code

In agent mode, `clerk init --app <id>` replaced an existing link to a different application without asking. Inside a Git repository the link is stored for the whole repository (by remote, else by its Git directory), so relinking one folder switched every project there. - `replacedLink()` in link says which link a new `--app` would replace, and over what scope: the repository, or only a folder's own link outside one. - `clerk init` stops with a usage error that names the current application and the scope, unless `--relink` is passed; with `--json` it also prints an `input-required` status. A new `--starter` app is checked before it is written, and a project init generates in a blank directory before it is linked. The stop offers `--app <linked>` to share the application. - Human mode keeps `clerk link`'s own confirmation. - The native-init E2E test now expects the stop, then `--relink`.

Walkthrough

Agent-mode clerk init --app now checks whether the requested application would replace an existing link. It stops with a usage error unless --relink is supplied, and JSON mode reports input-required. The new replacedLink helper determines replacement scope from repository and folder link state. Tests and documentation cover the guard, and an end-to-end test verifies both unconfirmed and confirmed relinking.

Merge Risk: Low · up to 03ac4

Agents following the iOS setup prompt may repeat a stopped command instead of asking before switching applications. Update that guidance; the remaining risk is bounded.

Explanation

The title names the main change: agent-mode clerk init stops instead of silently relinking a repository. It matches the raw summary, the PR description, and the objectives, which all describe the new stop-unless---relink behavior for --app. The title is concise, specific, and follows the conventional-commit style.

Handle link decisions in the iOS agent prompt.

The prompt currently tells agents to rerun the same command for every input-required result. A relink response must not be rerun unchanged because the CLI requires --relink to switch applications. Ask the user to approve the switch, then rerun with --relink; otherwise keep the current link or stop. The existing link.question, current, and requested fields provide the required data.

Suggested prompt update

-selection-required and `input-required` exit with a nonzero code and print a usage error, but they ask for input rather than report a failure: resolve only the missing information below from the JSON on stdout and rerun the same setup command. Don't run a separate dry run unless the user asks for a preview. +`selection-required` and `input-required` exit with a nonzero code and print a usage error, but they ask for input rather than report a failure. Resolve only the missing information below from the JSON on stdout.

Do not rerun the unchanged command for a link decision. Don't run a separate dry run unless the user asks for a preview.
