src/cli/index.ts at lines 368-371 and 458-459 to capture the result and report

preserve its existing failure handling. In tests/claude-shell-hook.test.ts lines
53-72, add a CRLF .zshrc fixture verifying the owned block is removed while
unrelated content remains.

I cannot approve the current head because it is 16 commits behind the current dev tip (caf20353f). The existing diff and CI results therefore predate a material set of integration changes.
Please rebase this focused change onto the latest dev, resolve any conflicts without carrying unrelated commits, rerun the focused checks plus the full exact-head suite, and re-request review. This is a review-state blocker, not a rejection of the fix direction.
The .zshrc hook was appended whenever system-env injection succeeded, so a user who never installed Claude Code still got an OpenCodex-owned block sourcing a file for a CLI they do not have, and a stale block survived uninstalling it. Write the hook only when an executable claude is discoverable on PATH, and reconcile rather than append: when Claude Code or system-env integration is gone, remove the OpenCodex-owned block and leave every user line untouched. Empty PATH segments are ignored so a workspace-local file is never mistaken for a durable installation, and a failed removal is reported as failed instead of reported as absent. Carries @lilinxiong's #2105 implementation and tests. Added a note on the intended failure direction: "installed" is answered from the PATH of the calling process, so a service context with a stripped PATH can remove a hook an interactive shell would have kept. That is reversible on the next foreground ocx start, whereas a hook pointing at an uninstalled CLI is the stale state this reconciliation exists to clear. Closes #2105
…ccess Two defects CodeRabbit found on #2144. uninstallShellHook matched the owned block with LF-only newlines. A .zshrc with CRLF endings -- ordinary on a home directory an editor or another OS has touched -- did not match, so the file was rewritten unchanged while the caller was told the hook was removed. The hook kept sourcing on every new interactive shell and the reported state said it did not. The pattern now accepts CR?LF and verifies the marker is gone before claiming removal; a block shaped differently is reported failed. Both cli/index.ts call sites discarded the result, so state: "failed" -- the one outcome the user has to act on -- was never surfaced. They now print the reason and where to look.

Match only the exact OpenCodex-owned hook block.
Line 125 accepts any bracketed line that contains claude-env.sh. It also does not anchor the marker to a complete line. A user-modified hook command can match this pattern, be deleted, and return removed: true.
Build the pattern from the exact two lines in SHELL_HOOK_LINE. Allow CRLF between those lines. Preserve the captured preceding line delimiter. Add a regression test with a marker followed by a modified bracketed command and verify that reconciliation returns failed without changing .zshrc.
Proposed fix
- const cleaned = content.replace(/\r?\n?# opencodex claude-env hook\r?\n\[.*claude-env\.sh.*(?:\r?\n)?/g, "\n");
+ const escapedHook = SHELL_HOOK_LINE
+ .split("\n")
+ .map(line => line.replace(/[.*+?^${}()|[\]\\]/g, "\\$&"))

Summary
The
.zshrchook was appended whenever system-env injection succeeded, so a user who never installed Claude Code still got an OpenCodex-owned block sourcing a file for a CLI they do not have — and a stale block survived uninstalling it.Credit: @lilinxiong's #2105 is the implementation and test suite carried here.
The hook is now written only when an executable
claudeis discoverable on PATH, and the operation is a reconcile rather than an append: when Claude Code or system-env integration is gone, the OpenCodex-owned block is removed and every user line is left untouched. Empty PATH segments are ignored so a workspace-local file is never mistaken for a durable installation, and a failed removal is reported as failed instead of silently reported as absent.One thing worth stating plainly
"Installed" is answered from the PATH of the calling process. A launchd/service context with a stripped PATH can therefore fail to see a
claudethat the user's interactive shell finds, and will remove the hook.That is the intended failure direction rather than an oversight: removing an OpenCodex-owned block is reversible on the next foreground
ocx start, whereas leaving a hook pointing at an uninstalled CLI is exactly the stale state this reconciliation exists to clear. Only our own marked block is ever touched. I added that reasoning as a comment onreconcileShellHookso the next reader does not have to rediscover it.Verification
