[AI091]

Claude wrappers such as a plain ~/.local/bin/claude launcher could still offer claude update, even when the native-path classifier rejected them. The shared maintenance resolver fell back to that updater, leaving a button that could report success without updating the owning installation.

Claude now opts into manual fallback through the shared maintenance definition. Proven native symlinks and the recognized Windows native path retain Claude updates; known package owners retain their manager actions. Unproven Claude wrappers remain manual-only. Other providers retain their existing fallback behavior, including when their native-path predicate rejects a path.

Verification on head 529d9a9c6a68f8a6902ce679edd775c380fd61f5:

• Replaced the original two-case driver test file with two cases in the existing shared resolver suite. The shared suite grows from 51 to 53 cases; total affected cases stay at 53 across one file instead of two.
• Before the resolver fix: 48 passed, five failed, demonstrating the wrapper and unowned-path fallback bug. After: 53/53 passed, including actual temporary-file native symlinks, forwarding wrappers, and an unowned OpenCode executable, package owners, simulated Windows contexts, and fallback for other providers with rejected native-path predicates.
• Provider-core and server typechecks, scoped lint, formatting, and diff checks passed. Checks ran serially with nice -n 10; Vitest used --maxWorkers=2.
• Review round 1 found that a generic predicate guard also removed Codex/OpenCode fallback updates. Two existing cases reproduced that regression (51 passed, two failed); the Claude-only policy restores all 53 passes. Fresh full-diff Opus and Sol round 2 reviews found no blockers.

No installed provider was updated. No live Settings interaction or native installation upgrade was exercised. Windows coverage uses simulated resolution contexts on Linux; macOS, Windows, iOS, Android, and Electron desktop were not verified live. Prior contributor recordings are historical evidence, not verification of this rebuilt head.

Thanks @AI091 for the wrapper reproduction and native-install comparison in #14170. Original commits are preserved, with current main merged in.

Implementation: GPT-6.1 Sol; tests: GPT-6 Astra; independent reviews: Claude Opus 5.5 and GPT-6 Sol. Harnesses: Codex and Claude Code through T3 Code.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — The production change is a narrow correction that prevents one-click Claude updates for unproven wrapper paths while preserving native-install updates. Human review is required because the new test file adds a file-level suppression for a static-analysis diagnostic.

Walkthrough

Claude’s native-updater path check now recognizes versioned Claude paths and no longer treats ~/.local/bin/claude as native. Tests cover native, XDG-native, and wrapper installations. Provider-update documentation clarifies fallback and manual-update behavior.

Changes: Claude maintenance detection and guidance

Layer / File(s)	Summary
Native Claude path detection and tests apps/server/src/provider/Drivers/ClaudeMaintenance.ts, apps/server/src/provider/Drivers/ClaudeMaintenance.test.ts	The native-updater path check requires a command path, excludes ~/.local/bin/claude, and recognizes paths containing /claude/versions/. Tests cover native, XDG-native, and wrapper layouts.
Provider update guidance docs/internals/providers.md, docs/user/install.md	The documentation states that Pi and Grok use native updaters when installer ownership is unproven. It directs users to update unrecognized Claude, Codex, and OpenCode installations through their original installers.

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix · Severity of issue fixed: Medium

Possibly related issues

• OpenCode update targets a Vite+ shim that delegates to another install (shimMode system_first), then reports "still outdated" #22741: Both changes concern updater selection when command paths involve wrappers or shims. This change adjusts Claude path detection, but does not address Vite+ system-first delegation.

Merge Risk: Low · up to 2e585

Claude installs reached through unusual layouts can still get an update button that does not change the installed version: a custom symlink to a Homebrew install, or a path pointing directly at a versioned binary. The update is reported as unchanged rather than corrupting anything, and ordinary native, npm and wrapper installs behave as intended. Tightening the path check is worthwhile but need not block the merge.

Review details

Systems and components

• observed — apps/server (service) was modified; 2 changed files map to changed impact.

Before / after behavior

• observed — Modified behavior in apps/server/src/provider/Drivers/ClaudeDriver.ts: isClaudeNativeCommandPath no longer classifies paths ending in /.local/bin/claude as native. Paths ending in /.local/bin/claude.exe and paths containing /.local/share/claude/ remain classified as native; the added comment describes the launcher distinction.
• observed — Modified behavior in apps/server/src/provider/Drivers/ClaudeDriver.test.ts: Adds an isolated test layer and temporary Claude installation fixtures. On non-Windows hosts, verifies that the native layout resolves an update command for the binary, while the wrapper layout resolves null; the test also fails if the disabled driver makes an HTTP request or spawns a process.

Full details: Description check

Explanation

The description clearly explains the problem, implementation, affected provider behavior, verification results, limitations, linked issues, and review context. It does not use the template headings or explicitly document maintainer approval, but it provides the required information well enough for a focused fix.

Full details: Linked Issues check

Explanation

The PR satisfies the coding objectives for [#27697] and [#28486]. Claude sets requiresCommandPath: true and removes the plain ~/.local/bin/claude match. An unproven wrapper, including a Nix-store target, does not receive claude update. Proven native paths include the native version layouts and the recognized Windows path. The resolver can therefore continue to select a proven package owner such as Homebrew before using a native update. The shared and Claude maintenance tests cover wrappers, native symlinks, XDG native paths, package owners, Windows contexts, and provider fallback regressions. The optional Nix-specific hint is not an acceptance requirement in the linked issues.

Full details: Out of Scope Changes check

Explanation

The resolver tests, Claude fixture changes, and provider documentation support the linked provider-maintenance objectives. Coverage for Codex, OpenCode, and other providers protects existing shared-resolver behavior after the Claude-specific policy change. No demonstrated unrelated product behavior appears in the reviewed changes.

Note

This comment is posted by Julius' dot

The native/wrapper regression tests and before/after recordings support this narrower wrong-owner guard: it preserves native Claude updates and leaves wrappers manual-only, without adding mise upgrade support.

Under the direction and scope requirement, could a maintainer confirm whether the provider-layer deferral in #9225 also covers this guard against current main, or whether this focused repair can proceed? V2 is still maintained separately in #14567. Please record that decision here so this can be routed appropriately; leaving it open pending clarification.

[charlielockyer-rice]

This fixes the no-op button for me too. One small follow-up idea: when the install is manual-only because it's managed by mise (T3 already detects /mise/installs/ and /mise/shims/), the popup could say so, e.g. "Installed with mise. Update it with mise upgrade claude." Just text, not running it. Right now it's hard to tell why there's no update button or what to do instead.

[juliusmarminge]

Taking over this one as maintainer for batch claude-04. I will preserve your commits, rebuild the regression in the shared maintenance resolver tests, and finish ownership detection against current main. Thanks for the wrapper reproduction and native-install comparison.

Keep fixed version paths manual-only.

If binaryPath points directly to /custom/claude/versions/2.1.314, this condition selects the native updater. Claude installs a new version and updates its managed launcher, but the configured version path stays fixed. T3 continues to run the old version. Require a launcher that the updater can move before offering the update action. (code.claude.com)

Check Homebrew ownership before accepting this path.

A symlink at /home/me/claude/versions/bin/claude can point to a Homebrew keg. The native predicate matches the symlink, so the resolver selects claude update before checking the real path. This bypasses brew upgrade and may leave the Homebrew installation unchanged.

Exclude Homebrew-shaped real paths from Claude’s native branch, and add a regression fixture for this symlink.

Suggested fix in maintenanceResolver.ts

     nativeUpdate?.isCommandPath &&
     commandPaths.some(nativeUpdate.isCommandPath) &&
-    !npmGlobalPrefixFromCommandPath(context.realCommandPath, packageName)
+    !npmGlobalPrefixFromCommandPath(context.realCommandPath, packageName) &&
+    !(definition.provider === "claudeAgent" &&
+      homebrewOwnershipFromCommandPath(context.realCommandPath))

Evidence

Enable an outdated, unrecognized .local/bin/claude wrapper, then open Settings → Providers → Claude → update advisory. Both runs use Chromium at 1280×800, light theme, fresh isolated state, and the same version-only executable fixture. The fixture's account-status warning is expected on both sides. Local paths are redacted; recordings are cropped excerpts.

Not shown:

• Actual Nix installation and /nix/store symlink resolution were not exercised; the captured reproduction uses the explicitly reported unrecognized-wrapper case.
• Homebrew ownership and brew upgrade were not exercised; no Homebrew installation was provisioned.
• Recognized native installations, custom XDG native paths, and Windows launchers were not exercised.
• No updater was executed. The proof covers whether the real app offers an update action, not the resulting installed version.
