Wait for the free limit to reset to keep reviewing this public repository. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

222-250: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick winConsider caching the assembled document.
buildSpecrunsscanAppDirectory(process.cwd())on every request to the spec route, and the response setscache-control: no-store. Each view therefore repeats a full filesystem walk of the app directory plus the registry reads.The filesystem scan cannot change inside a process for a deployed app, so it is the cheapest part to memoize. Cache the scan result per process, and keep the registry read per request so dynamically created content still appears immediately.

Inline comments:
In `@apps/playground/nextly.config.ts`:
- Around line 86-89: Update the comment describing the api-docs plugin to
document the actual `/admin/api/docs` route and its `/spec.json` and
`/scalar.js` endpoints, and state that the “API Docs” sidebar entry links there;
remove the incorrect plugin-path URL.
In `@packages/admin/src/components/layout/sidebar/SubSidebarContent.tsx`:
- Around line 111-115: Update the explanatory comment near SubSidebarContent to
remove the plan identifier “D20” while preserving the description of declarative
plugin-contributed menu items and the existing behavioral context.
In `@packages/nextly/src/plugins/routes/collect-routes.ts`:
- Around line 62-73: Update the admin-api collision validation in collectRoutes
to reject routes whose first path segment starts with ":" in addition to
reserved system-resource names, and add a regression test covering an admin-api
route such as "/:resource".
In `@packages/nextly/src/plugins/routes/route-path.ts`:
- Around line 24-28: Update the contract comment for the route-path function to
document both mount modes: standard routes receive the plugin namespace, while
the admin-api mount intentionally returns route.path directly because it
bypasses that prefix. Include a concise explanatory comment with the TypeScript
change.
In `@packages/nextly/src/plugins/routes/route-registry.ts`:
- Around line 133-134: Update the fullPath documentation to state that
namespacing applies only to non-admin-api mounts, while admin-api routes retain
route.path unchanged. Keep the contract accurate for consumers of
pluginRouteFullPath and the fullPath property.
In `@packages/nextly/src/plugins/routes/route-types.ts`:
- Around line 73-85: Remove the “Plan P5” references from the documentation
comments for the openapi property and PluginRouteOpenApi interface, while
preserving their descriptions of the code and behavior.
In `@packages/nextly/src/route-handler/content-surfaces.ts`:
- Around line 74-98: Update listContentSurfaces so each registry lookup,
getAllCollections and getAllSingles, is independently wrapped with rejection
handling that returns an empty projection for that surface. Preserve successful
records projection and ensure one failed registry does not prevent the other
surface from being listed or cause the function to reject.
In `@packages/plugin-api-docs/package.json`:
- Around line 28-29: Update the test:watch script in package.json to run
scripts/vendor-scalar.mjs before starting Vitest, matching the existing build,
dev, check-types, and test workflows.
In `@packages/plugin-api-docs/src/__tests__/scan.test.ts`:
- Around line 72-88: Update the decoy export in the test at
packages/plugin-api-docs/src/__tests__/scan.test.ts lines 72-88 to include an
extra verb such as DELETE, and revise the inline comment accordingly; make the
same fixture change at lines 267-274 so both tests depend on stripComments. Use
extractExportedNames and the shared health fixture as anchors, with no other
changes required.
In `@packages/plugin-api-docs/src/components/envelopes.ts`:
- Around line 59-67: Update the MutationResponse schema’s required fields to
include item alongside message, then add a schema test verifying that message
and item are required while warnings remains optional.
In `@packages/plugin-api-docs/src/fields.ts`:
- Around line 23-98: Update scalarSchema to honor FieldLike.hasMany for
multi-valued relationship, upload, select, and radio fields by returning an
array schema whose items preserve the existing scalar schema; keep single-valued
fields unchanged and ensure select/radio enums remain on the item schema.
In `@packages/plugin-api-docs/src/generate.ts`:
- Around line 75-154: Update expandContentOperations so templated
definition-level operations remain in the output when their corresponding
surface list is empty, while retaining per-surface expansion when entries exist.
Preserve the documented distinction between definition-level templated
operations and generated slug-specific operations, and keep the existing schema
and permission substitution behavior for expanded entries.
In `@packages/plugin-api-docs/src/layering.test.ts`:
- Around line 21-25: Replace the blocklist-based FORBIDDEN check with an
allowlist validation that rejects every non-permitted module specifier,
including side-effect, dynamic-import, and require forms. Update the per-file
assertion to collect disallowedSpecifiers and retain a code comment describing
the enforced boundary and rationale.
In `@packages/plugin-api-docs/src/paths.ts`:
- Around line 93-98: Update buildPaths() and the operation-building flow so each
template variable in op.path produces a parameter with the matching name, in set
to path, and required set to true; preserve existing operation parameters and
avoid duplicates. Add a test asserting every {name} segment has exactly one
corresponding required path parameter.
In `@packages/plugin-api-docs/src/plugin.ts`:
- Around line 44-49: Update the package ESLint configuration to recognize the
generated .txt asset extension for import-x/no-unresolved, preferably by adding
.txt to the existing node resolver extensions in eslint.config.mjs. Keep the
rule enabled and do not add an inline eslint-disable; alternatively ensure the
vendor-scalar script runs before lint on a clean checkout.
- Around line 87-108: Update normalizeDocsPath to reject a normalized docsPath
of "/" with the same validation error used for paths lacking a leading slash,
before docsRoutePaths can derive routes. Preserve normalization and acceptance
of valid non-root absolute paths.
In `@packages/plugin-api-docs/src/scan.ts`:
- Around line 179-212: Update extractExportedNames so export-list renames use
the right-hand exported name after as, preserving the original name when no
rename exists; this must make export { get as GET } detect GET and avoid
treating GET as exported in export { GET as legacyGet }. Also update the export
const branch to extract the identifier before an optional type annotation, so
declarations such as export const GET: Handler are recognized while retaining
existing filtering behavior.
- Around line 343-408: Harden walkRoutes and scanAppDirectory against filesystem
races and symlink cycles: track visited real paths (or skip symlinked
directories) before recursing, and guard each route-file read so deleted or
unreadable files are skipped instead of aborting the scan. Preserve
classification and unrecognized-file handling for successfully read files.
In `@packages/plugin-api-docs/tsconfig.json`:
- Around line 2-9: Add a concise comment near the include/exclude settings in
the TypeScript configuration explaining that production builds compile only
source files and omit test files. Keep the existing build boundaries unchanged.
In `@packages/plugin-api-docs/vitest.config.ts`:
- Around line 3-7: Add a concise comment near testTimeout and hookTimeout in
defineConfig explaining the operational reason both Vitest timeouts require
30000 milliseconds; leave the timeout values unchanged.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
A docsPath of "/" produces double-slash route paths.
normalizeDocsPath("/") strips the trailing slash, yields an empty string, and falls back to "/". docsRoutePaths then builds "//spec.json" and "//scalar.js", and the docs route claims the admin API root itself. The registry matcher splits on "/" and drops empty segments, so the registered path and the served URL disagree.
Reject a root docsPath the same way a missing leading slash is rejected.
🐛 Proposed fix
function normalizeDocsPath(raw: string | undefined): string {
- const path = (raw ?? DEFAULT_DOCS_PATH).replace(/\/+$/, "") || "/";
+ const path = (raw ?? DEFAULT_DOCS_PATH).replace(/\/+$/, "");
if (!path.startsWith("/")) {

`apiDocsPlugin: docsPath must start with "/" (got "${raw}")`

}
+ // The admin API root cannot be the docs base: the derived spec and bundle
+ // paths would collapse to "//spec.json", which the route matcher normalizes
+ // away, so the registered path and the served URL disagree.
+ if (path === "/") {
+ throw new Error(

Guard the file read and the directory recursion.
Two robustness gaps break the fault-tolerance this module states at Line 378-380:
- Line 393 reads each route file without a guard.
walkRoutescatches its own errors, but a file that is deleted or becomes unreadable between the walk and the read throws and aborts the whole spec request.buildSpecinpackages/plugin-api-docs/src/plugin.ts(lines 222-250) calls this per request, so one bad file removes the entire document. statSyncfollows symlinks, so a symlinked directory cycle underapp/makeswalkRoutesrecurse without bound and overflow the stack. Track visited real paths, or uselstatSyncand skip symlinked directories.

Make generated OpenAPI operation IDs unique per mount.
The admin and public media mounts both emit IDs such as listMedia. OpenAPI requires each operationId to be unique. Client generators can overwrite or reject duplicate operations.
Derive one mount-qualified ID from the service, mount base, and operation for both media and health mappings. Add a test whose separating property is that every generated operationId is unique when both media mounts exist.

| Finding | Fix |
|---|---|
Dynamic first segment (:resource) on admin-api routes shadows REST |
Rejected at boot (collect-routes.ts) + 2 regression tests |
Path {param} segments never declared as parameters |
Every templated segment now emits a required in: path parameter + doc-wide test |
import-x/no-unresolved on clean checkout (vendored .txt) |
Vendor script now runs before lint AND test:watch — file exists before eslint resolves it |
| Public media mount could document writes if scan reported the verb | Write descriptors hard-filtered (!op.write) for non-admin mounts + hostile-scan test |
Duplicate operationIds across the two media mounts |
Mount-qualified ids (listMedia.admin / listMedia.public) + uniqueness test |
| Empty content kind silently dropped templated ops | Templated op kept when the surface list is empty (no silent half-spec) + test |
respondMutation always carries item but schema said optional |
MutationResponse now requires item (verified against core's signature) |
Minor — fixed

PR Summary
feat(api-docs): add plugin-based OpenAPI docs with Scalar
What
Adds
@nextlyhq/plugin-api-docs— a new first-party plugin that generates a complete OpenAPI 3.1 spec on demand and serves an interactive Scalar API reference, all from a singleapiDocsPlugin()registration in the Nextly config.Why
Nextly had no built-in API documentation. Users and integrators had to reverse-engineer the REST surface manually. This plugin makes the full API surface discoverable and interactive, without requiring any manual spec authoring — everything is derived at request time from the running app.
How it works
The plugin assembles the spec from three derived sources, each backed by a new read-only introspection seam in core:
scanAppDirectory()(plugin-local)listAdminRestOperations()(new innextly)listPluginRoutes()(new innextly)openapi?annotationContent schemas (collections, singles, field groups) are resolved from the runtime registries first (covers dynamic Schema Builder content without restart) and fall back to config.
New package:
packages/plugin-api-docsRoutes contributed (mounted at the admin API root, not the plugin namespace):
GET /admin/api/docs— interactive Scalar reference page (HTML)GET /admin/api/docs/spec.json— the OpenAPI 3.1 document (admin-gated by default)GET /admin/api/docs/scalar.js— self-hosted Scalar bundle (no CDN dependency)Key design decisions:
