🤖 Fix all issues with AI agents
In `@docs/COURSE_COMPARISON_FEATURE.md`:
- Around line 148-150: The fenced code block showing the example request
"/courses/compare?courses=MAL401,MAL402" is missing a language specifier; update
that block to include a language identifier (e.g., "text" or "http") so the
snippet is syntax-highlighted and accessible—locate the fenced block containing
"/courses/compare?courses=MAL401,MAL402" and change the opening backticks to
include the chosen language (for example, ```text).
In `@src/app/api/extract-themes/route.ts`:
- Around line 52-102: The Gemini fetch call (creating geminiResponse) has no
timeout; wrap the request with an AbortController, pass controller.signal into
the fetch options for the gemini request, start a timeout (e.g., setTimeout to
call controller.abort() after a chosen ms) and clearTimeout on success, and
update the route handler's catch block to detect an AbortError (error.name ===
'AbortError') and return a 504 NextResponse.json({ error: 'Theme extraction
timed out' }); ensure you reference the existing geminiResponse fetch invocation
and clear the timeout to avoid leaks.
- Around line 52-53: The fetch call that creates geminiResponse currently sends
the API key in the URL query string; change the request to call the same
endpoint without the ?key=... suffix and pass the API key via the
"x-goog-api-key" header instead. Update the geminiResponse fetch invocation to
include an options object (method, headers, body) and add "x-goog-api-key":
geminiApiKey to headers (keep other headers and the JSON body intact). Ensure
the request URL is
"https://generativelanguage.googleapis.com/v1beta/models/gemini-1.5-flash:generateContent"
and remove any query-parameter usage of geminiApiKey.
In `@src/app/api/generate-summary/route.ts`:
- Around line 73-89: The prompt embeds raw user reviews via the reviewsText
interpolation in the prompt (see reviewsText in
src/app/api/generate-summary/route.ts), which allows prompt-injection; fix by
sanitizing/escaping or structuring the input: sanitize each review string
(remove/escape instruction-like tokens such as "ignore", "system", "assistant",
or long-form prompts), or better, pass reviews as structured data to the model
(e.g., include reviews as a JSON payload or as a separate non-instruction
message) and send fixed system/instruction messages that never include raw user
content; update the code that builds the prompt to use the sanitized/structured
reviews and keep the template literal (the instruction block) static so user
text cannot inject new instructions.
- Around line 4-13: The POST handler destructures courseCode and courseTitle but
does not validate them, causing "undefined" to appear in the Gemini prompt;
update the POST function to either validate and return a 400 when courseCode or
courseTitle are missing (similar to the existing courseId check) or assign safe
defaults (e.g., empty string or "Unknown") before using them in the prompt;
modify the destructuring/validation in POST and ensure any later use of
courseCode/courseTitle (in the Gemini prompt construction) uses the validated or
defaulted values.
- Around line 61-102: The fetch call that creates geminiResponse lacks a timeout
and may hang; wrap the request in an AbortController with a timer (e.g., create
AbortController(), set a setTimeout to call controller.abort() after your
desired timeout) and pass controller.signal into the fetch options for the
request that builds the Gemini payload, clear the timeout after fetch completes,
and handle the abort/timeout case (detect AbortError or signal.aborted) in the
surrounding handler that constructs the response so you return a proper error
instead of hanging; modify the code where geminiResponse is awaited to include
the controller, timeout, and cleanup.
- Around line 61-62: The fetch call that creates geminiResponse currently
appends geminiApiKey as a query parameter; remove the key from the URL and move
authentication into the request headers by adding 'x-goog-api-key': geminiApiKey
and 'Content-Type': 'application/json', and ensure the fetch options include
method: 'POST' and the JSON body used by generateContent; update the call site
that builds the request body so it passes JSON.stringify(...) in the fetch
options instead of relying on URL params (refer to geminiResponse, geminiApiKey
and the fetch invocation in route.ts).
In `@src/app/courses/compare/page.tsx`:
- Around line 20-31: The component currently calls useSearchParams() in a
statically rendered page which will fail in production; wrap the subtree that
uses useSearchParams (e.g., the CourseComparisonPage or the component exported
from page.tsx) in a React Suspense boundary with a fallback (import Suspense
from 'react') so the CSR bailout is isolated, or alternatively stop calling
useSearchParams() here and accept searchParams as a prop from a parent Server
Component; update the default export (Page) or the parent layout to render
<Suspense fallback={...}> around the component that reads search params.
In `@src/components/courses/compare/ComparisonCharts.tsx`:
- Around line 69-77: The radarData is built per course but the RadarChart
expects data per metric; change the shape so each element represents a metric
(e.g., { metric: 'Overall', courseA: 4.5, courseB: 3.8, ... }) by iterating
metrics ['overall','difficulty','workload','reviews'] and mapping each course's
value into keys named by course.code (use Math.min(course.review_count/10,5) for
reviews); then update the RadarChart rendering to generate one <Radar> per
course (use course.code as dataKey and colors[idx % colors.length] for
fill/stroke) so each radar trace reads its values from the metric-shaped
radarData and the chart displays one trace per course. Ensure references to
radarData, courses, colors, and the RadarChart/Radar components (the existing
Radar rendering block) are updated accordingly.
In `@src/components/courses/compare/ComparisonTable.tsx`:
- Around line 63-73: The renderers in ComparisonTable.tsx call toFixed on
numeric fields (e.g., course.overall_rating, course.difficulty_rating,
course.workload_rating) which will throw if the value is null/undefined; update
each renderer to defensively check the value before calling toFixed (or coerce
to a safe default number) and render a fallback (e.g., '-' or 'N/A') when
missing; ensure you also pass a safe numeric value into StarRating (or handle
its props) so it never receives undefined—refer to the render lambda that
returns the <div> with StarRating and the span showing
course.overall_rating.toFixed(1) (and the equivalent renderers for
difficulty_rating and workload_rating) to apply the checks.
In `@src/components/courses/compare/CourseSelector.tsx`:
- Around line 130-134: CourseSelector currently calls
course.overall_rating.toFixed(1) which can throw if overall_rating is
null/undefined; update the display logic in the CourseSelector component to
defensively handle missing ratings by normalizing the value (e.g., use a default
like 0 or fallback text) before calling toFixed, e.g., check
course.overall_rating != null or coalesce with 0 (refer to course.overall_rating
in the JSX) so the UI never invokes toFixed on undefined/null.
In `@src/components/courses/compare/ReviewHighlights.tsx`:
- Around line 70-72: The reviews fetch branch currently swallows errors; modify
the block handling the reviews fetch (the conditional around
reviewsByUUID[course.id] = data) to log the error when the fetch fails using the
same logger/mechanism used for the UUID fetch error, and include course.id (or
course identifier) in the log so failures for a specific course are traceable;
keep the existing behavior of assigning data when no error.
In `@src/components/courses/CompareButton.tsx`:
- Around line 25-29: getComparisonList currently calls JSON.parse on
localStorage data which can throw on corrupted JSON; wrap the parse in a
try-catch inside getComparisonList (checking typeof window first remains), and
on parse failure return an empty array (optionally remove the bad STORAGE_KEY or
log the error) so the component doesn't crash when stored data is invalid.
In `@src/components/courses/CompareCoursesButton.tsx`:
- Around line 11-15: getComparisonList currently calls JSON.parse on
localStorage.getItem(STORAGE_KEY) without handling malformed JSON; wrap the
parse in a try-catch inside getComparisonList so that if JSON.parse throws you
return an empty array (and optionally clear the corrupted STORAGE_KEY or log the
error), ensuring the component won't break when stored data is invalid.
In `@src/components/courses/course_page/AddToComparison.tsx`:
- Around line 22-25: Normalize and dedupe the comparison list inside
setComparisonList by removing duplicate course IDs before writing to
localStorage and dispatching the update event; update the implementation in
setComparisonList to create a deduplicated array (preserving order) from the
incoming courseIds, JSON.stringify and store that deduped array, then dispatch
'comparison-list-updated'. Also apply the same normalization wherever the
comparison is updated/created (the related update handlers around lines 45-52)
so stored lists never contain duplicates and the 4-item cap behaves correctly.
- Around line 16-20: getComparisonList currently calls JSON.parse on
localStorage data which can throw or return non-array values; wrap the parse in
a try/catch, validate the parsed value is an array of strings, and return [] on
error or invalid shape. In the getComparisonList function, read
localStorage.getItem(STORAGE_KEY) then try JSON.parse inside try/catch, check
Array.isArray(result) and that every item is typeof 'string' (or coerce/ignore
non-strings), and optionally remove the malformed STORAGE_KEY entry before
returning [].
In `@src/components/courses/course_page/CourseSummary.tsx`:
- Around line 22-24: In generateSummary, the loading state is incorrectly set to
false at the start; change the initial call to setIsLoading(true) (leave
setError(null) as-is), and ensure setIsLoading(false) is called in the promise
resolution path (e.g., in a finally block or after catch) so the spinner shows
while the API request runs; update any try/catch/finally around generateSummary
to guarantee setIsLoading(false) on both success and error.
- Around line 154-158: The empty-state copy in the CourseSummary component is
misleading—update the JSX in CourseSummary.tsx (the empty-state div that
currently says "Click 'Generate Summary' to analyze student reviews") to reflect
the actual UI action (e.g., "Click 'Refresh' to analyze student reviews" or a
neutral message like "No reviews available; click Refresh"), so the placeholder
matches the existing "Refresh" button and won't confuse users.
- Around line 56-59: The useEffect that auto-generates a summary calls
generateSummary but omits it from the dependency array, risking a stale closure;
fix by either wrapping generateSummary in useCallback (so its identity is
stable) and then adding generateSummary to the useEffect deps, or by inlining
the summary-fetching logic directly inside the useEffect and keeping [courseId]
as the dependency; ensure you reference the generateSummary function and the
courseId variable when updating dependencies.
🧹 Nitpick comments (17)
.env.example (1)
9-11: Minor formatting nits from static analysis.The static analysis tool flagged two minor issues:
- Key ordering:
NEXT_PUBLIC_SUPABASE_ANON_KEYshould come beforeNEXT_PUBLIC_SUPABASE_URLalphabetically- Missing blank line at the end of the file
These are low-priority style nits. The important thing is that
GEMINI_API_KEYcorrectly lacks theNEXT_PUBLIC_prefix, ensuring it remains server-side only.💅 Optional fix for linter warnings

3-3: Remove unused import.
useEffectis imported but not used in this component.🧹 Remove unused import
-import { useState, useEffect } from 'react'; +import { useState } from 'react';
69-74: Consider adding accessible label to the remove button.The remove button uses only an icon (
X), which may not be accessible to screen readers. Adding anaria-labelimproves accessibility.♿ Proposed fix for accessibility
<button onClick={() => handleRemoveCourse(course.id)} className="ml-1 hover:text-destructive transition-colors" + aria-label={`Remove ${course.code} from comparison`} > <X className="h-3 w-3" /> </button>src/components/courses/CompareCoursesButton.tsx (2)
36-38: Consider replacingalert()with a more polished notification.Using
alert()blocks the UI thread and provides a jarring UX. Consider using a toast notification component for a more seamless experience, especially since this is a user-facing action.
9-9: CentralizeSTORAGE_KEYto avoid drift.The
STORAGE_KEYconstant is duplicated across three comparison-related components:CompareCoursesButton.tsx,CompareButton.tsx, andAddToComparison.tsx, all with the same value ('course_comparison_list'). Moving this tosrc/constants(which already exists in the codebase) would prevent accidental mismatches if the key name needs to change.src/app/api/extract-themes/route.ts (2)
6-6: Remove unusedcourseCodefrom destructuring.
courseCodeis extracted from the request body but never used in the route handler. Either remove it or use it (e.g., in logging or the prompt for additional context).🧹 Proposed fix
- const { courseId, courseCode } = await request.json(); + const { courseId } = await request.json();
16-22: Consider adding rate limiting or caching for this endpoint.This endpoint fetches reviews and calls an external AI API on every request. For popular courses, this could lead to:
- Excessive Supabase queries
- High Gemini API costs
- Rate limiting from Google
Consider caching the extracted themes (e.g., in Supabase or Redis) with a TTL, and only regenerating when reviews are updated.
src/components/courses/course_page/CourseKeyThemes.tsx (2)
24-56: Missing loading state initialization before fetch.Line 27 sets
setIsLoading(true), but the initial state on Line 21 already setsisLoadingtotrue. This is fine for the initial mount but causes a brief flash if re-fetching. Also,courseCodeis included in the dependency array but isn't validated before calling the fetch.Consider simplifying: either remove Line 27 (redundant on mount) or validate both props:
🔧 Suggested improvement
- if (courseId) { + if (courseId && courseCode) { fetchKeyThemes(); }
30-36: Consider using GET instead of POST for data retrieval.This endpoint fetches data without side effects, which aligns better with GET semantics. Using POST for read-only operations can cause issues with caching and doesn't follow REST conventions. If POST is required for payload size reasons, this is acceptable but worth documenting.
src/components/courses/CompareButton.tsx (1)
62-65: Replacealert()with toast notifications.Using
alert()blocks the main thread and provides poor UX. Consider using a toast notification system (if available in your UI library) for a more polished experience.Also applies to: 120-123
src/components/courses/compare/ReviewHighlights.tsx (2)
56-73: N+1 query pattern: Sequential fetches can be optimized.The code fetches reviews for each course in a sequential loop, resulting in N database calls. This can be optimized by batching the query using
.in('target_id', uuids)and then grouping results client-side.♻️ Suggested optimization
- // Fetch reviews for each course UUID - for (const course of courses) { - const uuid = codeToUUID[course.code.toUpperCase()]; - if (!uuid) continue; - - const { data, error } = await supabase - .from('reviews') - .select('id, comment, rating_value, difficulty_rating, workload_rating, created_at, target_id') - .eq('target_id', uuid) - .eq('target_type', 'course') - .not('comment', 'is', null) - .order('created_at', { ascending: false }) - .limit(10); - - if (!error && data) { - reviewsByUUID[course.id] = data; - } - } + // Batch fetch reviews for all course UUIDs + const uuids = Object.values(codeToUUID); + if (uuids.length === 0) { + setLoading(false); + return; + } + + const { data: allReviews, error } = await supabase + .from('reviews') + .select('id, comment, rating_value, difficulty_rating, workload_rating, created_at, target_id') + .in('target_id', uuids) + .eq('target_type', 'course') + .not('comment', 'is', null) + .order('created_at', { ascending: false }); + + if (!error && allReviews) { + // Group by target_id and limit to 10 per course + const uuidToCourseId = Object.fromEntries( + courses.map(c => [codeToUUID[c.code.toUpperCase()], c.id]) + ); + for (const review of allReviews) { + const courseId = uuidToCourseId[review.target_id]; + if (!courseId) continue; + if (!reviewsByUUID[courseId]) reviewsByUUID[courseId] = []; + if (reviewsByUUID[courseId].length < 10) { + reviewsByUUID[courseId].push(review); + } + } + }
140-147: Potential undefined value for Tabs defaultValue.If
courses[0]?.idis undefined (empty array case), the Tabs component may behave unexpectedly. While line 110 guards against empty courses, adding a fallback is safer.🔧 Suggested fix
- <Tabs defaultValue={courses[0]?.id} className="w-full"> + <Tabs defaultValue={courses[0]?.id || ''} className="w-full">src/app/courses/page.tsx (1)
5-7: Consider handling loading state for courses.The
useCourseshook returns{ courses, isLoading, error }, but onlycoursesis destructured. TheComparisonFloatingButtonreceivescourseswhich may be empty while loading. Per the relevant code snippet forComparisonFloatingButton, it returnsnullwhen no courses are selected, but the initial empty courses array during loading could cause brief UI inconsistencies.This is a minor concern since the floating button handles empty selection gracefully, but for consistency with the comparison page (
src/app/courses/compare/page.tsxlines 18, 22) which usesisLoading, you may want to handle the loading state here as well.Also applies to: 19-19
src/components/courses/compare/ComparisonTable.tsx (1)
143-163: Consider using a stable key instead of array index.Line 147 uses
idxas the key forTableRow. While thecomparisonRowsarray is stable within a render, usingrow.labelas the key would be more semantically correct and resilient to future changes.♻️ Suggested fix
- <TableRow - key={idx} + <TableRow + key={row.label} className="hover:bg-muted/30 transition-colors" >src/components/courses/compare/ComparisonCharts.tsx (2)
31-34: Remove unusedgetDepartmentColorfunction.This helper function is defined but never used in this component. It appears to be copy-pasted from
ComparisonTable.tsx. Consider removing it to reduce dead code.♻️ Suggested fix
- const getDepartmentColor = (department: string) => { - const dept = departmentProperties.find((d) => d.name === department); - return dept?.color || '#718096'; - }; -Also remove the unused import on line 20:
-import departmentProperties from '@/constants/department';
44-67: Remove unusedidxparameter from reduce callbacks.The
idxparameter is declared but never used in the reduce callbacks. This is a minor cleanup.♻️ Suggested fix
{ metric: 'Overall', - ...courses.reduce((acc, course, idx) => { + ...courses.reduce((acc, course) => { acc[course.code] = course.overall_rating; return acc; }, {} as Record<string, number>), },Apply similar changes to the other reduce callbacks on lines 55 and 62.

163-163: Documentation claims memoization that isn't implemented.The documentation states "Charts data is memoized to prevent unnecessary recalculations", but the
ComparisonCharts.tsxcomponent doesn't useuseMemofor its data transformations (ratingsData,radarData,creditsData). Consider either implementing memoization or updating the documentation to be accurate.

Add a timeout to the Gemini API fetch request.
The fetch call to the Gemini API has no timeout configured. If the external service is slow or unresponsive, this could cause the request to hang indefinitely, potentially exhausting server resources.

🌐 Web query:
Gemini API authentication methods query parameter vs Authorization header
💡 Result:
For the Google Gemini API (Google AI for Developers / Generative Language API), the authentication method determines whether you use a query parameter or an HTTP header:
1) API key (recommended header; query param is fallback)
- Header (preferred): send your key in
x-goog-api-key.- Gemini API docs show requests using
x-goog-api-key. [1] - Google Cloud’s general guidance for API keys also recommends
X-goog-api-key. [2]
- Gemini API docs show requests using
- Query parameter (fallback):
?key=YOUR_API_KEY- Google Cloud docs note this works when you can’t set headers, but it exposes the key in URLs (logs, proxies, browser history), so it’s less safe. [2]
2) OAuth 2.0 access token (Authorization header)
- Use the standard header:
Authorization: Bearer ACCESS_TOKEN. [3][4]
3) Live API ephemeral tokens (special case)
- Ephemeral tokens can be sent either:
- as an
access_tokenquery parameter, or - in
Authorization: Token <token>(auth-schemeToken, notBearer). [5]
- as an
Bottom line:
- Use
x-goog-api-keyheader for API keys (avoid putting keys in the URL). [1][2] - Use
Authorization: Bearerfor OAuth. [3][4] - Only use query parameters when the specific feature requires it (e.g., Live API ephemeral tokens) or headers are impossible. [2][5]
Sources: [1] Gemini API reference (ai.google.dev), [2] Google Cloud “Use API keys” doc, [3] Gemini OAuth quickstart (ai.google.dev), [4] Google Cloud REST auth doc, [5] Gemini ephemeral tokens doc (ai.google.dev).
Use x-goog-api-key header instead of query parameter.
The Gemini API supports passing the API key via the x-goog-api-key header, which is Google's recommended approach. Query parameters expose the key in server logs, CDN logs, and browser history. Change the request to use the header method instead:

Normalize the comparison list to prevent duplicates from inflating counts.
Without de-dupe, the same course ID can appear multiple times (e.g., cross-component updates or stale storage), which can block adding new courses due to the 4-item cap. Consider normalizing in setComparisonList.

Preselecting courses from the courses query param is currently case-sensitive (courseIds.includes(c.id)), but course IDs in result.json are lowercase while users may paste/share uppercase codes. Normalizing the parsed IDs (e.g., .map(id => id.toLowerCase().trim())) before matching would make share links more robust.

Unqualified uuid_generate_v4() calls in DEFAULT expressions may fail in some environments.
Extensions are installed in the extensions schema (lines 6-7), but DEFAULT clauses at lines 20, 22, 31, 46, 72, 96, 108, and 530 call unqualified uuid_generate_v4(). This depends on search_path configuration and will cause INSERT failures if the extensions schema is not in the search_path.

course_update and professor_update policies allow unrestricted updates by any authenticated user.
The policies use USING (true) WITH CHECK (true), enabling any authenticated user to directly modify course and professor records. This contradicts the authorization model where INSERT and DELETE are restricted to admins. While the comment notes these policies "allow trigger updates," triggers execute independently through their own security context (SECURITY DEFINER functions) and do not justify open direct access. Direct user updates should still be restricted to admins via USING (is_admin()) WITH CHECK (is_admin()), consistent with insert/delete policies and other sensitive operations like flag_update.

🌐 Web query:

In supabase-js, .select() returns an object like:
data: the rows (array) unless you sethead: truecount: the total number of rows matched only if you passcount: 'exact' | 'planned' | 'estimated'error: any error
With head: true
Supabase sends a HEAD request, so no rows are returned:
const { data, count, error } = await supabase
.from('characters')
.select('*', { head: true, count: 'exact' })
// data === null
// count === (number of matching rows)This is expected: head returns no data, so data is null; the row total is in count. [1][2]
With head: false (default)
You can get both rows and count:
const { data, count, error } = await supabase
.from('characters')
.select('*', { count: 'exact' })
// data === Row[]
// count === total matching rowsNote: by default Supabase limits returned rows to 1,000 per request (so data.length may be ≤ 1000 even when count is larger). [1]
Sources:
[1] Supabase docs: JavaScript select() (examples incl. { count: 'exact', head: true }, and 1,000 row default)
[2] Supabase GitHub discussion: “Count comes back in count. Head returns no data so null.”
Professor count will always display zero with head: true.
When using .select() with head: true, the response's data field is null (no rows returned). Line 20 attempts to access professors?.length, which evaluates to undefined, and the fallback || 0 always results in displaying "0 records" regardless of actual row count.
Use the count field from the response instead:

In `@src/app/api/analyze-sentiment/route.ts`:
- Around line 8-12: The route currently uses the caller-supplied
SentimentRequest.comment when calling Gemini and persisting sentiment; instead,
after validating reviewId, fetch the canonical review record (e.g., via your
existing review lookup function or collection) and use the stored review text
(e.g., storedReview.text or storedReview.comment) for the sentiment analysis
call and when saving the sentiment result; also handle the case where the review
is not found and return an error. Update all code paths that call Gemini or
persist sentiment (including the blocks referenced around 108-124 and 133-176)
to replace usage of SentimentRequest.comment with the fetched stored review
field and keep validation and error handling intact.
In `@src/app/api/batch-analyze-sentiment/route.ts`:
- Around line 42-45: Validate and cap the caller-controlled limit in the POST
handler before any processing begins: in the POST(Request) function (handling
BatchAnalysisRequest with { limit, targetType, reviewIds }), coerce limit to an
integer, enforce a hard maximum (e.g., maxLimit = 100) and a minimum of 1, and
replace the incoming value with the capped value before using it to slice
reviewIds or drive the batch loop; also apply the same validation/cap to any
subsequent code paths in this file that consume limit (the batch-processing loop
and any logic between lines ~83-148) to ensure a single request cannot trigger
an unbounded number of AI calls or long sleeps.
- Around line 65-73: The current destructuring ignores Supabase errors (const {
data: analyzedReviews } = await
supabaseAdmin.from('review_sentiments').select('review_id')), causing failures
to be treated as empty results and reprocessing already-analyzed reviews; update
the call to capture the response error (e.g., const { data: analyzedReviews,
error } = ...), check if error is truthy and fail fast (throw or return an HTTP
500) from this route handler instead of proceeding, and only build analyzedIds
from analyzedReviews when there is no error; reference supabaseAdmin,
analyzedReviews, analyzedIds and the surrounding route handler to locate where
to add the error check and early exit.
In `@src/app/api/generate-summary/route.ts`:
- Around line 67-72: In the catch block in route.ts (the error handling around
generate course summary), stop echoing the raw exception message in the HTTP
response: keep the existing server-side logging (console.error or processLogger)
to record the full error, but change the NextResponse.json payload to a generic
body such as { error: 'Internal server error' } and retain the { status: 500 }
response; update the code that currently builds errorMessage from error
instanceof Error and removes it from the returned JSON while leaving the logging
call unchanged.
In `@src/app/courses/compare/page.tsx`:
- Around line 20-30: The useEffect that syncs selected courses from searchParams
only updates when a non-empty 'courses' param exists, leaving stale selections
when the param is removed; update the effect (the block containing
searchParams.get('courses') and setSelectedCourses) to explicitly clear
selections when the 'courses' param is missing or empty — i.e., compute
courseIds = searchParams.get('courses')?.split(',') || []; if courseIds.length >
0 then setSelectedCourses(preselectedCourses.slice(0,4)) else
setSelectedCourses([]) so selectedCourses is cleared when the URL no longer
contains the param.
In `@src/app/courses/page.tsx`:
- Line 18: The page currently calls useCourses() while
src/components/courses/ItemList.tsx also calls useCourses(), causing duplicated
loads; instead call useCourses() exactly once in the parent (page.tsx or a
new/top-level container), remove the duplicate hook calls from child components
(ItemList and ComparisonFloatingButton), and pass the resulting courses array
(and any loading/error state) down as props (e.g., courses, isLoading, error) to
ItemList and ComparisonFloatingButton; update ItemList and
ComparisonFloatingButton to accept those props (or read from a new
CoursesContext if you prefer a provider) and delete their internal calls to
useCourses() so network/db work is performed only once.
In `@src/lib/ai-service/summary.ts`:
- Around line 47-48: The entityName assignment can become undefined for
professor when metadata.name is missing; update the logic in the entityName
computation (used where targetType and metadata are checked) to provide a safe
fallback—e.g., if targetType === 'professor' use metadata.name ?? metadata.email
?? `Professor ${metadata.id ?? 'unknown'}` or a generic label like "this
professor"; ensure the ternary that defines entityName always returns a
non-empty string so the prompt never contains "undefined".
In `@src/lib/ai-service/themes.ts`:
- Around line 75-83: The code trusts model output when building validThemes;
tighten validation in the themes processing (the themes variable and validThemes
mapping) so ThemeData values are well-typed: ensure tag is a non-empty string,
sentiment is one of the expected enum values (e.g.,
"positive","negative","neutral") and reject any other strings, and
coerce/validate count to an integer (use parseInt or Number and default to 1 if
invalid or negative). Update the filter/map that produces validThemes to enforce
these checks (validate t.tag, check t.sentiment against allowedSentiments, parse
and clamp t.count) before returning ThemeData so downstream badge color and
count logic receives correct types/values.

reviewsText directly inside the instruction string (variable prompt), allowing

JSON-only requirement and output schema) separately from the untrusted data:
keep the instruction text in prompt (or as a system/message) and supply
reviewsText/targetType as a distinct input or structured variable (e.g., as a
separate user message or as JSON-escaped content) so the model receives
instructions and data separately and cannot be influenced by reviewer text;
update the code that builds prompt and the call site (references: prompt,

- Line 127: The documentation wrongly references adding a function to
src/lib/ai-service.ts; update the docs to point to the correct directory
src/lib/ai-service/ and show that new functionality should be added as a new

that directory; change the example line and any subsequent references from
src/lib/ai-service.ts to src/lib/ai-service/<module>.ts (or explicitly mention
themes.ts) so readers can find the correct location.
- Line 9: Update the documentation entry that currently lists
`/src/lib/ai-service.ts` so it points to the actual implementation structure
using the ai-service directory barrel export (i.e., reference the ai-service
index barrel export instead of a single file); edit the header line `### 1.
**/src/lib/ai-service.ts** (NEW)` to mention the ai-service directory/barrel
export (for example `### 1. **src/lib/ai-service (index.ts barrel)**`) so
developers are directed to the correct `ai-service` module location.
In `@src/app/api/extract-themes/route.ts`:
- Line 7: The destructured variable courseCode from the request body in the

processLogger.debug or similar) so it’s referenced; update the line in route.ts

In `@src/app/courses/compare/page.tsx`:
- Around line 24-27: The preselection logic using courses.filter loses the order

Array.prototype.find), filter out any not-found results, then slice(0, 4) and
pass that to setSelectedCourses so selectedCourses preserves the query order;
reference the existing preselectedCourses variable and the setSelectedCourses
call when making the change.
In `@src/lib/ai-service/client.ts`:
- Around line 50-55: The safetySettings array currently sets every
HARM_CATEGORY_* threshold to 'BLOCK_NONE', disabling filtering; update the
safetySettings (the safetySettings variable/array used when initializing the
client in client.ts) to use stricter defaults such as 'BLOCK_ONLY_HIGH' for at
least violent/dangerous/hate/sexually explicit categories (e.g., change entries
for HARM_CATEGORY_DANGEROUS_CONTENT, HARM_CATEGORY_HATE_SPEECH,
HARM_CATEGORY_SEXUALLY_EXPLICIT to 'BLOCK_ONLY_HIGH'), or make the thresholds
configurable and default to safer values; ensure the updated safetySettings is
passed into the same client initialization code that currently references
safetySettings so the new policy is enforced.
- Around line 110-120: The MAX_TOKENS repair code that mutates cleanedResponse
is fragile for nested JSON (it only appends a single closing bracket/brace), so
update the MAX_TOKENS handling in the block that checks finishReason ===
'MAX_TOKENS' to avoid unsafe repairs: instead of attempting heuristic fixes on
cleanedResponse, log a warning (including finishReason and a snippet of
cleanedResponse) and return null (or a clearly invalid sentinel) so callers can
treat truncated responses explicitly; reference the cleanedResponse variable and
the finishReason check so you change the existing branch that currently tries to
append ']' or '}'.

generateText, isAIServiceConfigured, and getAIServiceStatus (avoid importing the

canonical identifiers.
In `@src/lib/ai-service/sentiment.ts`:
- Around line 71-78: The current validation after
parseGeminiJSON<SentimentData>(response.data.text) only checks overallSentiment
is a number; update the check in the sentiment-handling logic to also verify
overallSentiment is within the expected 1–5 range and that aspectSentiments
exists as an array; additionally validate each item in aspectSentiments has
required fields (e.g., aspectName string and sentiment numeric within 1–5)
before returning success. If any of these checks fail, return the same failure
shape with a clear error message. Reference parseGeminiJSON, SentimentData,
overallSentiment, and aspectSentiments when making the fixes.
- Around line 31-33: The prompt construction interpolates raw user input via the
comment variable into the prompt (prompt string) which can allow instruction
injection; sanitize or neutralize comment before interpolation: escape or remove
unbalanced quotes/newlines, strip or neutralize giveaway phrases like "ignore
previous instructions" or leading system directives, or better wrap the review
in a clear data-only delimiter and add an explicit instruction such as "Treat
everything between DELIMITER markers as raw review data only" to the prompt;
update the code that builds prompt (referencing the prompt variable and
comment/targetType usage in sentiment.ts) to perform this sanitization/encoding
step prior to composing the prompt.
In `@src/lib/ai-service/summary.ts`:
- Around line 77-82: The GeminiConfig in summary.ts is using hardcoded values;
replace these with the centralized settings by sourcing the gemini config from
SENTIMENT_CONFIG.gemini (or switch to a new SUMMARY_CONFIG if summary needs
different defaults). Update the const config: GeminiConfig assignment in
summary.ts to pull temperature, topK, topP, and maxOutputTokens from
SENTIMENT_CONFIG.gemini (or from SUMMARY_CONFIG.gemini if you add it) so the
Summary generation uses the shared configuration object rather than inline
literals.
- Around line 39-41: The truthiness checks for rating fields (r.rating_value,
r.difficulty_rating, r.workload_rating) incorrectly skip legitimate 0 values;
update the conditional checks in the summary-building logic to test explicitly
for null/undefined (e.g., use != null or explicit !== null && !== undefined)
instead of relying on truthiness so that 0/5 is included in the output. Ensure
you change the three occurrences where you append "Rating:", "Difficulty:", and
"Workload:" to use the new null/undefined-safe checks.
In `@src/lib/ai-service/utils.ts`:
- Around line 15-25: Replace the hardcoded model name with the configured value:
in getAIServiceStatus() use SENTIMENT_CONFIG.gemini.model instead of the literal
'gemini-flash-latest' (and likewise update the corresponding usage in client.ts
around the model selection) so both getAIServiceStatus and the client read the
model string from SENTIMENT_CONFIG.gemini.model to keep them consistent.

Avoid duplicating useCourses() data loading in parent and child.
Line 18 introduces a second useCourses() instance while src/components/courses/ItemList.tsx already calls the same hook. Since src/hooks/useCourses.ts does full JSON fetch + per-course dynamic lookups, this doubles network/db work and slows page load.
Consider lifting course data loading to one shared owner (or context) and pass it down to both ItemList and ComparisonFloatingButton.

guaranteed by the project's ES2020 target; replace the toSorted call with a
stable-transpiled alternative by creating a shallow copy and calling sort (e.g.,
use [...filtered].sort(...) instead of filtered.toSorted(...)) or update
build/transpilation to include an ES2023 polyfill/target so toSorted is emitted
safely; locate the toSorted usage in the code where sorted is defined and change
it to use the copied-array + sort pattern (or adjust tsconfig/polyfills) to
avoid runtime errors on older engines.

There was a problem hiding this comment.
Validation is less strict than the single-review endpoint.
The batch route only checks minCommentLength (line 136) but skips maxCommentLength and minWordCount validation that the single route performs via preprocessComment. This inconsistency could result in:
- Processing comments that are too long (potentially hitting AI token limits)
- Processing comments with fewer than the minimum required words
Consider reusing the preprocessComment function from the single route or applying the same validation logic here.

Added an AI-driven feature that analyzes course reviews to automatically extract and display 6-8 key themes (e.g., "Heavy Workload", "Engaging Lectures", "Tough Exams") as color-coded badges in the course page sidebar. The feature uses Gemini AI to identify common topics with sentiment analysis (positive/negative/neutral) and frequency counts, helping students quickly understand course characteristics at a glance.
