Detection now returns every valid installation it finds (Homebrew + nvm + npm-global + custom wrappers like codex-multi-auth-codex), de-duplicated by canonical path. When more than one is present, the Path field in the agent config panel renders a dropdown so the user can pick which binary to use; the selection is persisted via the existing customPath store and becomes the default for future agents. Closes #1048
📝 WalkthroughWalkthroughThis PR adds multi-path binary discovery for agents. It refactors path-prober to enumerate all valid installation locations (not just the first), propagates those paths through type definitions, integrates discovery into agent detection, and provides a UI dropdown for users to choose which installation to use when multiple are found.

Confidence Score: 3/5Safe to merge for users who won't use the chooser in the Wizard or Director's Notes; the stale-state bug silently breaks persistence in those two contexts. The chooser's onChange handler calls the blur callback synchronously right after scheduling a React state update, so AgentSelectionScreen and EncoreTab will call setCustomPath / setDirectorNotesSettings with the previously-selected path rather than the one the user just picked. The user sees the right value in the UI but the wrong one gets persisted — a silent data-integrity failure on the primary feature path. Focus on AgentConfigPanel.tsx (the chooser onChange handler) and its callers AgentSelectionScreen.tsx and EncoreTab.tsx, where the blur callback reads stale state. Important Files Changed

customPath
onCustomPathChange(next) schedules a React state update (async), so customPath in the parent has not changed yet when onCustomPathBlur?.() fires immediately after in the same event handler. Callers that read the state value inside their blur handler — AgentSelectionScreen.tsx (const pathToSet = customPath.trim() || null then setCustomPath(pathToSet)) and EncoreTab.tsx (customPath: ac.customPath || undefined) — will therefore persist the previous path instead of the one the user just selected. The fix is to pass next directly into the blur callback, or refactor the callbacks to accept the new value as a parameter.

active can re-introduce a duplicate
findAllBinaryPaths de-duplicates by resolved canonical path (realpath), so if /usr/local/bin/codex and /opt/homebrew/bin/codex both point to the same binary, only one enters found. But found.includes(active) uses plain string equality, so when detection.path is /usr/local/bin/codex (what which returned first) and found already contains /opt/homebrew/bin/codex, the check returns false and active is prepended — giving the chooser two options that launch the exact same binary. The dedup step should resolve active via realpath and compare against the canonical keys already seen by findAllBinaryPaths.

Normalize path comparison before prepending active path.
Line 152 uses exact string comparison; on Windows this can duplicate the same path with different casing in allPaths. Normalize (or canonicalize) before the membership check.

Avoid silently swallowing lookup failures in findAllBinaryPaths.
Line 638-Line 640 catches and ignores all errors, which hides actionable diagnostics when environment expansion or lookup behavior regresses. Please explicitly handle expected failures (debug log with context) and rethrow/report unexpected ones.
As per coding guidelines: "Do not silently swallow errors. Let unhandled exceptions bubble up to Sentry for error tracking in production. Handle expected/recoverable errors explicitly (e.g., NETWORK_ERROR). For unexpected errors, re-throw them to allow Sentry to capture them."

Persisted path can be stale when selecting from the dropdown.
Line 450 updates state, then Line 452 immediately commits via blur callback. If the blur handler reads customPath from state, it may persist the previous value instead of next. Please commit using the selected value directly (e.g., pass next through the callback contract) or defer persistence until the state update is reflected.

Related feedback-flow regression filed as #1064. This PR likely needs explicit validation that Send Feedback uses the persisted/selected provider path when multiple Codex installs are present, especially when is the working auth wrapper. The current feedback UI auto-picks the first detected supported provider and can otherwise fail with a generic "Something went wrong" error. |

Thanks for picking this up — the chooser flow and realpath dedup logic are clean, and the new path-prober tests are nice. A couple of blockers before this can go in, plus two should-fixes the bots flagged that I'd like to double down on.
Blockers
1. Base branch / 793-file diff — please rebase onto current rc
This PR targets rc but the branch carries 655a089c7 ("test: add full unit coverage suite (#1040)"), which was squash-merged to main on May 25 and never landed on rc. That single commit is what's producing the 238k-line / 793-file diff and the mergeable_state: dirty — nothing wrong with the feature itself.
The change feels right for rc (UI polish, ships with the next release), so the fix is a rebase onto upstream/rc rather than retargeting to main. After the rebase the diff should shrink back to the ~8 files actually involved.
2. Chooser selection silently persists the previous path
src/renderer/components/shared/AgentConfigPanel.tsx:
onChange={(e) => {
const next = e.target.value;
onCustomPathChange(next); // schedules setState
onCustomPathBlur?.(); // runs synchronously, no value passed
}}onCustomPathBlur is then implemented by reading customPath out of closure in both call sites:
src/renderer/components/Wizard/screens/AgentSelectionScreen.tsx:939–945onCustomPathBlur={async () => { const pathToSet = customPath.trim() || null; // ← stale await window.maestro.agents.setCustomPath(configuringAgentId!, pathToSet); await refreshAgentDetection(); }}
src/renderer/components/Settings/tabs/EncoreTab.tsx:57(persistDnCustomConfigreadsac.customPath).
Net effect: pick path B → UI shows B → IPC writes A. The chooser appears to work but its primary purpose (persisting the selection) silently fails in the Wizard and Director's Notes contexts.
Smallest correct fix is to thread the value through the callback so the persistence path doesn't depend on the not-yet-committed React state:
// AgentConfigPanel.tsx
onCustomPathBlur?: (value?: string) => void;
onChange={(e) => {
const next = e.target.value;
onCustomPathChange(next);
onCustomPathBlur?.(next);
}}
// AgentSelectionScreen.tsx
onCustomPathBlur={async (value) => {
const pathToSet = (value ?? customPath).trim() || null;
await window.maestro.agents.setCustomPath(configuringAgentId!, pathToSet);
await refreshAgentDetection();
}}
// EncoreTab.tsx
const persistDnCustomConfig = (nextPath?: string) => {
setDirectorNotesSettings({
...directorNotesSettings,
customPath: (nextPath ?? ac.customPath) || undefined,
customArgs: ac.customArgs || undefined,
customEnvVars: Object.keys(ac.customEnvVars).length > 0 ? ac.customEnvVars : undefined,
});
};The value ?? customPath fallback keeps the existing onBlur-from-text-input path working unchanged. Worth a small RTL test that mounts AgentConfigPanel with allPaths.length > 1, fires change on the <select>, and asserts the persist callback was called with the selected value.
Should-fix
3. detector.ts merged step can re-introduce duplicates
src/main/agents/detector.ts:152:
const found = await findAllBinaryPaths(agentDef.binaryName); // already realpath-deduped
const active = detection.path;
const merged = active && !found.includes(active) ? [active, ...found] : found;findAllBinaryPaths correctly dedupes via fs.realpath + Windows lowercase, but this merge uses plain string Array.includes against detection.path. If detection.path is the symlink (/usr/local/bin/codex) and found already contains the canonical target (/opt/homebrew/Cellar/codex/.../bin/codex), both get pushed and the chooser shows two rows for the same binary. Same hazard on Windows with mixed casing.
Easiest path is to share the normalization from path-prober:
let activeKey: string | undefined;
try {
activeKey = active ? await fs.promises.realpath(active) : undefined;
} catch {
activeKey = active;
}
if (isWindows() && activeKey) activeKey = activeKey.toLowerCase();
const foundKeys = await Promise.all(found.map(async (p) => {
try {
const k = await fs.promises.realpath(p);
return isWindows() ? k.toLowerCase() : k;
} catch {
return isWindows() ? p.toLowerCase() : p;
}
}));
const merged = active && activeKey && !foundKeys.includes(activeKey)
? [active, ...found]
: found;Or factor the normalization out of findAllBinaryPaths into a small helper so both sites use the same logic.
4. Silent catch {} in findAllBinaryPaths
src/main/agents/path-prober.ts ~line 638:
} catch {
// which/where failures are non-fatal; we still have direct probe results
}CLAUDE.md is explicit about not swallowing exceptions — anything unusual here should reach Sentry. The detector a few lines down already gets this right (logger.debug('findAllBinaryPaths failed ...')); the prober just needs the same treatment:
} catch (err) {
logger.debug(
`which/where lookup failed for ${binaryName}`,
LOG_CONTEXT,
{ err },
);
}If you want to be more selective, you can match on the expected ENOENT/non-zero-exit modes and rethrow everything else, but a debug log is the minimum.
Other observations
- The two feature commits are authored as
Test User <test@example.com>rather than your usual identity. Worth cleaning up in the rebase. - @jeffscottward's comment about Send Feedback (#1064) honoring the persisted path when multiple Codex installs are present is unaddressed. PR #1067 fixed the error surfacing there but doesn't touch the path-selection side. Worth a manual smoke after this lands, since the chooser is now the source of truth for which Codex Send Feedback should reach for.
- Manual test row in the PR description (multi-install Codex chooser persistence across restart) is still unchecked — would be good to confirm post-rebase, especially with the closure fix in (2).
Happy to take another look once the rebase + (2) land.
