Summary

  • What changed?

The installer now identifies a plugin entry by the package it resolves to rather than by how its path is spelled, and appends oc-codex-multi-auth only when nothing already in the config resolves to this plugin. Cache eviction refuses any path that resolves outside the OpenCode cache directory. README, AGENTS.md, and the setup skill describe the local-checkout setup and what the installer does with it.

  • Why is this needed?

Anyone developing on this project points OpenCode at their clone rather than at the published package:

{ "plugin": ["file:///path/to/oc-codex-multi-auth"] }

Before this change, the next npx -y oc-codex-multi-auth@latest removed that entry and wrote the published package name in its place, in both opencode.json and tui.json. OpenCode then loaded npm's copy instead of the contributor's working tree. Nothing failed, so the swap was easy to miss - the symptom is edits that appear to have no effect - and the previous entry survived only in the timestamped backup file.

Renaming the clone did not avoid it. A directory not ending in /oc-codex-multi-auth passed the filter, but the published name was still appended beside it, leaving both copies registered at once. No directory name produced a correct result.

Now the entry is kept exactly as written, under any directory name, and whether it is written as a path, a file:// URL, or a build output directory, with nothing appended beside it. An entry carrying plugin options keeps its options. Contributors can run any installer mode without checking afterwards whether their config still points at their own build, and the installer prints which checkout it kept.

The same name-matching drove the exit-time cache refresh, which removed three paths recursively based on their final path segment alone. A checkout linked into ~/.cache/opencode/node_modules so OpenCode loads it was therefore deleted on the next exit with an update pending. Those paths are now resolved through their symlinks and must still be contained in the OpenCode cache directory to be removed; a path that escapes, a path that cannot be resolved, and the cache directory itself are refused and logged.

Stale references the installer itself produced are still retired, exactly as before: a repeated bare name, version pins, the former oc-chatgpt-multi-auth name, and paths into node_modules or the versioned package cache.

Testing

  • npm run lint
  • npm run build
  • npm test

npm test reports 3567 passed, 1 skipped, with no changes needed to existing expectations.

New coverage in test/install-oc-codex-multi-auth.test.ts: a checkout is preserved when referenced as a path, a file:// URL, a dist build output, a differently named directory, and a monorepo packages/ directory; package-manager references are still retired; an unresolvable path is preserved unless it is package-manager output; entries carrying plugin options are never rewritten; an unrelated local plugin is untouched while the published name is registered; and two end-to-end installer runs confirm a config registering a checkout is left byte-identical under both --plugin-only and --modern.

New coverage in test/auto-update-checker.test.ts: eviction is refused for a cache entry that resolves onto a linked working checkout, for a path outside the cache directory, for the cache directory itself, and for every path when the cache directory cannot be resolved.

Also verified outside the suite by running the built installer against a copy of a real OpenCode config that registers a checkout: opencode.json and tui.json were both left byte-identical and no backup file was written.

Compliance Confirmation

  • This change stays within the repository scope and OpenAI Terms of Service expectations.
  • This change uses official authentication flows only and does not add bypass, scraping, or credential-sharing behavior.
  • I updated tests and documentation when the change affected users, maintainers, or repository behavior.

Notes

  • Linked issue:
  • Follow-up work or rollout notes: a follow-up PR adds plugin origin self-identification, so the plugin reports which checkout it is running from and stops offering to update a build it did not install. It is written on top of this branch and depends on this one being accepted; if this PR changes during review, that branch will be rebased onto the merged result.

This PR is AI generated, but under direct supervision and on request of @Nowaker.

  2. P1 duplicate registrations remain
Fix with agent prompt
### Issue 1
scripts/install-oc-codex-multi-auth-core.js:272-276
if a checkout is linked or junctioned beneath the opencode cache, this lexical containment check classifies it as installer-managed even though its real target is developer-owned. normalization then discards the checkout entry and adds the published package name, silently making opencode load the published copy. this also affects windows junctions. add vitest coverage for a cache path that resolves through a symlink or junction to an external checkout.

### Issue 2
scripts/install-oc-codex-multi-auth-core.js:undefined-361
a config left by the previous installer can contain both a differently named local checkout and `oc-codex-multi-auth`. every local checkout is retained, and this branch independently retains one published entry. the installer therefore leaves the duplicate registration it is intended to repair. track one managed registration across both branches and add vitest coverage for local-plus-published and duplicate-local inputs.

Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

For each issue above, determine whether it is valid and should be fixed. If so, fix it directly.

Summary

this pr changes installer registration to preserve local checkouts and hardens runtime cache eviction against paths escaping the opencode cache.

  • plugin entries are classified using package metadata and their origin.
  • relative paths and windows path casing receive dedicated handling.
  • installer and runtime cache behavior gain substantial vitest coverage.
  • documentation now explains local-checkout registration and cache updates.

Reviews (3) · Last reviewed commit: "fix(installer): stop keeping a cache cop..."

A config that points OpenCode at a working clone of this repository lost
that entry on the next install. Any path ending in `/oc-codex-multi-auth`
was read as an installer-written reference, removed, and replaced with the
published package name, so the next request ran against npm rather than
the code being edited - silently, with the previous entry recoverable only
from the backup file.

Renaming the clone did not help. A differently named directory survived the
filter, but the published name was still appended beside it, leaving both
copies registered at once. No directory name produced a correct result.

Entries are now identified by the package they resolve to, read from the
nearest enclosing `package.json`, rather than by how the path is spelled. A
path outside `node_modules` and the versioned package cache is somewhere a
human deliberately pointed OpenCode, so it is kept byte-identical, whatever
the directory is called and whether it is written as a path, a `file://`
URL, or a build output directory. An entry carrying plugin options keeps
its options. The published package name is appended only when nothing in
the config resolves to this plugin.

References the installer itself produced are still retired: a repeated bare
name, version pins, the former `oc-chatgpt-multi-auth` name, and paths into
`node_modules` or the versioned package cache.

The exit-time cache refresh deleted three paths recursively, each chosen
purely because its final segment matched a managed package name. A
developer who links a working checkout into the OpenCode cache so OpenCode
loads it - `npm link`, or a symlink under `node_modules` - therefore lost
that checkout the next time OpenCode exited with an update pending.

Every path is now resolved through its symlinks and must still be contained
in the OpenCode cache directory before it can be removed. A path that
escapes, a path that cannot be resolved, and the cache directory itself are
refused and logged rather than deleted.

Developing on this project means pointing OpenCode at a clone rather than
at the published package, but nothing said so, and the install commands
were presented without noting that they write the reader's real OpenCode
config.

README gains a section on that setup and on what the installer does with
it. AGENTS.md separates the installer from the standalone CLI commands it
had been listed beside, since only the installer writes config, and records
that a plugin entry is identified by what it resolves to rather than by its
last path segment. The setup skill tells an agent to read the existing
`plugin` array before installing, and to prefer `update` when the goal is
only a stale package cache.

Review of ndycode#259 found four ways the new classifier still reached the
wrong answer. Each one ends with OpenCode loading two copies of this
plugin, or none.

A relative entry was never resolved, so its package.json was never read.
OpenCode resolves such an entry against the config file that declares
it, so `./plugins/my-codex-fork` names a real checkout; the installer
saw an unreadable path, called it unrelated, and appended the published
name beside it. The declaring config directory is now passed down and
used to resolve relative entries FOR INSPECTION ONLY - the entry itself
is still written back exactly as the user spelled it.

A checkout and the published name could both survive. The published
entry was kept whenever it appeared, independently of any checkout, so
a config left by an older installer kept the duplicate registration
this change exists to repair. Registration is now decided once, across
the whole list, before any entry is kept.

A checkout of the FORMER package name satisfied that registration. It
is user-owned, so it is still never removed, but `oc-chatgpt-multi-auth`
is valid for cleanup and not as the registration the installer must
ensure - a config holding only a legacy checkout now also gets the
current package registered.

Windows reaches one directory under many spellings, so a `NODE_MODULES`
path there is the same package-manager output as `node_modules` and was
being preserved as if a human had chosen it. Segment comparison is now
case-insensitive on win32 only; elsewhere the two are different
directories and must stay so.

Thanks — four of the five findings were real defects, and I confirmed each one by running the reported input through the pre-fix matcher before changing anything. All five are addressed in a2ce671.

1. Relative checkout paths get duplicated — real, fixed

Raised independently by @greptile-apps (P1, :281) and @coderabbitai (:281), and correct on both counts.

resolveDeclaredPackageName rejected every non-absolute path before reading package.json, so a relative entry could never be identified by the package it resolves to. Verified against the old code:

normalizePluginList(["other", "../../my-codex-fork"], …, { baseDirectory: <configDir> })
  before: ["other", "../../my-codex-fork", "oc-codex-multi-auth"]   <- both registered
  after : ["other", "../../my-codex-fork"]

The fix follows the guidance exactly: a new resolveInspectionPath resolves a relative entry against the declaring config directory, and that resolved path is used only for reading metadata. The entry written back to the config is the original specifier, byte for byte. runInstaller passes paths.configDir down through normalizePluginList and mergeTuiConfig, so opencode.json and tui.json both get it.

One deliberate detail: with no declaring directory (the unit-test path, and any caller that has not supplied one), a relative entry is left alone rather than resolved against the installer's working directory. That directory is not where OpenCode would look, so resolving there would identify a different place entirely. There is a test for both halves of this.

2. Duplicate registrations remain — real, fixed

@greptile-apps (P1, :361). Also verified:

normalizePluginList(["/tmp/…/my-codex-fork", "oc-codex-multi-auth"])
  before: ["/tmp/…/my-codex-fork", "oc-codex-multi-auth"]   <- two copies of one plugin
  after : ["/tmp/…/my-codex-fork"]

The two branches each tracked registration independently, exactly as described. normalizePluginList now classifies the whole list first and derives a single checkoutRegistered fact from it, so a published-name entry is retired when a checkout of the current package already covers it. New coverage for local-plus-published and duplicate-local inputs.

3. A legacy checkout satisfies current registration — real, fixed

@coderabbitai (:351). A checkout declaring oc-chatgpt-multi-auth set registered = true, so the current package never got registered at all:

normalizePluginList(["/tmp/…/my-legacy-fork"])
  before: ["/tmp/…/my-legacy-fork"]                            <- plugin not registered
  after : ["/tmp/…/my-legacy-fork", "oc-codex-multi-auth"]

Implemented as suggested in substance: the legacy path is still user-owned and kept untouched, but only a checkout whose declared name is PACKAGE_NAME counts as the registration. I hoisted the check out of the loop rather than using registered ||= inside it, because finding 2 needs the answer before deciding what to do with a published entry that appears earlier in the array.

4. Windows path casing misclassifies — real, fixed

@greptile-apps (P2, :245). Correct: NODE_MODULES on Windows is the same directory as node_modules, so a package-managed path spelled in caps was being treated as a user-owned checkout and retained.

classifyPluginEntry("C:/app/NODE_MODULES/oc-codex-multi-auth")
  before            : local-checkout
  after  (win32)    : managed-package
  after  (linux)    : local-checkout

Segment casing is now folded only on win32; on POSIX the two spellings are genuinely different directories and must stay distinguishable. The platform is injectable so both branches are covered by tests.

To be straight about the limits of this one: I cannot execute it on Windows here, so the win32 behaviour is verified by injecting platform, not by running on the OS. The junction case the comment mentions is unchanged and still relies on the path as written — a junction whose own path contains no package-manager segment is treated as a checkout, which I believe is the right default (a junction somebody created by hand is a deliberate choice), but I have not exercised it on a real junction.

5. AGENTS.md contradicts the cleanup contract — real, fixed

@coderabbitai (AGENTS.md:78). The rule said "outside node_modules" while the installer also retires entries under the versioned OpenCode package cache. Rather than the more abstract "recognized package-manager output", I named both concretely, since the rule's job is to stop a future reader guessing:

a path outside package-manager output - node_modules, and the versioned directories of the OpenCode package cache - belongs to whoever wrote it and is never rewritten or removed.

Testing

test/install-oc-codex-multi-auth.test.ts is 43 tests, all passing, with six added for the cases above: a differently named relative checkout, a relative entry with no declaring directory, local-plus-published dedup, duplicate locals, a legacy-named checkout, and win32 vs POSIX segment casing. npm run lint, npm run build, and npm run typecheck are all clean.

Full-suite numbers are noisier than I would like and I would rather say so than quote a flattering figure: this machine was running at a load average above 50 throughout, and test/index.test.ts failed 277/277 on the unmodified base commit while passing 277/277 on the modified tree in the same minute. I compared every file that failed, base versus branch, back to back at the same load — no file fails on the branch that passes on the base.

@Nowaker CodeRabbit's GitHub chat credential is not a code-delivery check. Repository permission fields and authentication errors from that credential do not say whether the separate coding workflow can create a branch or pull request. When you approve a code change, that workflow attempts delivery with its own credential and reports GitHub's concrete success or error; that result is authoritative.

Thanks for the detailed validation. The five reported defects are addressed in a2ce671:

  • Relative checkout paths are inspected from the declaring config directory while preserving the original specifier (scripts/install-oc-codex-multi-auth-core.js:245, with config-directory wiring near :1538 and :1574).
  • Registration is deduplicated across the whole plugin list, so a current-package checkout removes a neighboring published entry (scripts/install-oc-codex-multi-auth-core.js:361). Legacy checkouts remain preserved without satisfying current-package registration.
  • Package-manager path matching folds segment casing only for win32, with injected-platform coverage for Windows and POSIX behavior (test/install-oc-codex-multi-auth.test.ts:1230).
  • Cache eviction rejects paths outside the cache, the cache root itself, unresolved roots, and symlink-resolved working checkouts before recursive deletion (lib/auto-update-checker.ts:121).

The added tests cover the reported installer and cache regressions, including option-bearing entries and end-to-end relative checkouts. The lack of execution on a Windows host and the absence of new concurrency/token-redaction tests are noted limitations, but neither is a blocker for this change. No further blocking finding remains.

used to resolve relative entries FOR INSPECTION ONLY - the entry itself
is still written back exactly as the user spelled it.

A checkout and the published name could both survive. The published
entry was kept whenever it appeared, independently of any checkout, so
a config left by an older installer kept the duplicate registration
this change exists to repair. Registration is now decided once, across
the whole list, before any entry is kept.

A checkout of the FORMER package name satisfied that registration. It
is user-owned, so it is still never removed, but `oc-chatgpt-multi-auth`
is valid for cleanup and not as the registration the installer must
ensure - a config holding only a legacy checkout now also gets the
current package registered.

Windows reaches one directory under many spellings, so a `NODE_MODULES`
path there is the same package-manager output as `node_modules` and was
being preserved as if a human had chosen it. Segment comparison is now
case-insensitive on win32 only; elsewhere the two are different
directories and must stay so.

An entry pointing into OpenCode's package cache at
`<cache>/packages/oc-codex-multi-auth` survived normalization as a local
checkout, because classification recognized only the versioned
`packages/<name>@<version>` spelling the cache usually writes. The
unversioned directory is a cache layout too, and `clearCache` removes it
on the same run, so the installer preserved an entry and then deleted
what it pointed at. OpenCode then had a config naming a plugin
directory that no longer existed.

Spelling could not separate the two: `packages/oc-codex-multi-auth` is
also how an ordinary monorepo names its own package, and treating every
unversioned `packages/` directory as cache would retire those real
checkouts. Ownership can. The installer already knows its cache root and
already empties it, so an entry resolving to somewhere inside that root
is one the installer wrote and may retire, whatever it is called. A
monorepo lives elsewhere and is untouched.

Classification takes the cache root the same way it takes the config
directory, so the containment question is answered against a path the
caller supplies rather than one guessed here. Windows path casing folds,
since one directory is reachable there under several spellings.

Containment is compared on the path as written, without resolving
symlinks, which is the opposite of what the cache eviction path does and
is deliberate. Eviction decides whether to delete a directory
recursively, so it must refuse anything whose real location escapes the
cache. This decides whether an entry names something `clearCache`
removes, and `clearCache` removes the paths exactly as it spells them -
`rm` unlinks a symlink rather than descending into its target. Resolving
here would preserve an entry whose link is about to be unlinked out from
under it, which is the failure this commit exists to end.

P1 linked checkouts get replaced

if a checkout is linked or junctioned beneath the opencode cache, this lexical containment check classifies it as installer-managed even though its real target is developer-owned. normalization then discards the checkout entry and adds the published package name, silently making opencode load the published copy. this also affects windows junctions. add vitest coverage for a cache path that resolves through a symlink or junction to an external checkout.

- Do not hardcode ports other than OAuth callback port `1455`; use existing constants/helpers.
- Do not remove `store: false` or `reasoning.encrypted_content` from shipped config templates.
- Do not treat `oc-chatgpt-multi-auth` as current except in migration/cleanup logic.
- Do not identify a plugin entry by the spelling of its last path segment. Resolve what it points at; a path outside package-manager output - `node_modules`, and the versioned directories of the OpenCode package cache - belongs to whoever wrote it and is never rewritten or removed.

Document all OpenCode cache directories.

isPackageManagerPath returns true for any resolved plugin path inside cacheDirectory, including unversioned packages/<name> paths. classifyPluginEntry therefore marks them as managed, and normalizePluginList removes them. The test covers both unversioned and versioned paths. Change “the versioned directories of the OpenCode package cache” to “the directories of the OpenCode package cache” so the guidance matches the installer.

Do not treat an unresolved path as a registered checkout.

When resolveDeclaredName returns null, managedNameFromPathSpelling classifies /old/oc-codex-multi-auth as the current package. normalizePluginList then sets checkoutRegistered and does not append the published package.

Restrict basename fallback to package-manager paths. This preserves cleanup for missing node_modules and cache entries while treating missing user-owned paths as unrelated. Update the POSIX casing test to expect an unrelated entry for its nonexistent uppercased NODE_MODULES path.

Proposed correction
 const inspectionPath = resolveInspectionPath(entryPath, baseDirectory);
 const declaredName = inspectionPath ? resolveDeclaredName(inspectionPath) : null;
+const packageManagerPath = isPackageManagerPath(entryPath, {
+	platform,
+	cacheDirectory,
+	inspectionPath,
+});
 const managedName = declaredName
 	? getManagedPackageNames().find(
 		(managed) => managed.toLowerCase() === declaredName.toLowerCase(),
 	  ) ?? null
-	: managedNameFromPathSpelling(entryPath);
+	: packageManagerPath
+		? managedNameFromPathSpelling(entryPath)
+		: null;

 if (!managedName) return { kind: UNRELATED_ENTRY, name: null };

-return isPackageManagerPath(entryPath, { platform, cacheDirectory, inspectionPath })
+return packageManagerPath
 	? { kind: MANAGED_PACKAGE_ENTRY, name: managedName }
 	: { kind: LOCAL_CHECKOUT_ENTRY, name: managedName, path: inspectionPath ?? entryPath };
