Inline comments:
In `@services/.env.example`:
- Around line 1-2: The env var names in the template (GROQ_API_KEY, MONGO_URI)
don't match the runtime lookups (groq_key, url); update the code to use a single
naming scheme—prefer the uppercase names from the template. Replace any uses of
groq_key with GROQ_API_KEY and url with MONGO_URI in the runtime code (e.g., in
the DB connector in config/db.py and the consumer in controllers/symptoms.py) so
os.getenv()/process.env lookups use the same keys as .env.example, and ensure
any error messages or defaults reference the same variable names.
In `@services/app.py`:
- Around line 18-19: The startup block is hardcoding debug=True which exposes
internals; update the if __name__=="__main__": app.run(...) invocation to read
the debug flag from an environment variable (e.g., FLASK_DEBUG or an application
config flag) and convert it to a boolean before passing it to app.run, or omit
debug entirely in production. Locate the main entry (the if __name__=="__main__"
block and the app.run call) and replace the literal True with a value derived
from os.environ (or app.config) so debug mode is controlled by configuration
rather than hardcoded.
In `@services/config/db.py`:
- Around line 5-8: Replace the use of os.getenv("url") with the documented
MONGO_URI environment variable and validate it before creating the MongoClient:
call load_dotenv(), read mongo_uri = os.getenv("MONGO_URI"), check that
mongo_uri is a non-empty string and raise a clear runtime error (or log and
exit) if missing, then pass mongo_uri into MongoClient instead of url; update
the symbols referenced (os.getenv("url") -> os.getenv("MONGO_URI"),
MongoClient(url) -> MongoClient(mongo_uri)) to ensure fail-fast behavior with a
clear message.
In `@services/controllers/symptoms.py`:
- Around line 30-33: The call to client.chat.completions.create in
check_symptoms is unhandled and can raise groq.APIError, timeouts, or network
exceptions; wrap the call in a try/except around
client.chat.completions.create(...) inside check_symptoms, catch groq.APIError
and relevant network/timeout exceptions (e.g.,
requests.exceptions.RequestException or socket.timeout depending on HTTP
client), log the exception, and return a graceful error response (HTTP 502/503
with a JSON error message) instead of letting the exception propagate.
- Around line 7-9: The Groq client is being initialized using
os.getenv("groq_key") which doesn't match the .env.example's GROQ_API_KEY;
update the Groq client initialization (the client=Groq(...) call) to use
os.getenv("GROQ_API_KEY") and add a startup validation after load_dotenv() that
checks the env value (e.g., groq_key or groq_api_key variable) and logs a clear
error and exits (or raises) if it's missing so the app fails fast instead of
failing silently at API call time.
In `@services/routes/symptoms_route.py`:
- Around line 13-14: Wrap the external call to check_symptoms in the
symptoms_route handler with a try/except that catches
network/HTTP/auth/rate-limit errors from the Groq client and returns structured
JSON responses with appropriate status codes; for transient/unavailable service
errors return a 502 with a message, for rate-limit errors return a 503 (or
inspect the exception for 429 and return 429), and for unexpected exceptions
return a 500—include the error message in the JSON body for debugging and ensure
you still return via jsonify({"reply": ...}) or jsonify({"error": ...}), using
the Flask response tuple (body, status_code) to set the HTTP status.
- Around line 7-13: Guard against non-JSON payloads by first obtaining the body
safely (use request.get_json(silent=True) or check request.is_json) and handle
None before accessing .get(); validate that s_id, u_id, and msg are present and
non-empty, and if any are missing return jsonify({"error": "missing fields",
"missing": [...]}) with a 400 status code instead of 200; finally pass the
validated s_id, u_id, msg into check_symptoms and keep using jsonify for the
success response. Ensure you update references to data, s_id, u_id, and msg in
this route so no .get() is called on None and that validation failures return
HTTP 400.

Environment variable names are inconsistent with runtime lookups.
services/.env.example uses GROQ_API_KEY / MONGO_URI, but runtime currently reads different keys (groq_key and url). A clean setup using this template will fail to authenticate/connect.
Please standardize one naming scheme across services/.env.example, services/config/db.py (Line [6]), and services/controllers/symptoms.py (Line [8]).

Use documented MONGO_URI environment variable and validate before MongoClient initialization.
The code uses os.getenv("url") but .env.example documents MONGO_URI. Additionally, there is no validation—if the environment variable is not set, MongoClient(None) will fail silently or hang. Align with the documented configuration key and fail fast with a clear error message.

Wrap the external API call with error handling.
client.chat.completions.create(...) is a network dependency with no error handling. Groq API failures (timeouts, rate limits, service unavailability) will propagate as unhandled exceptions, causing hard 500 errors without user-friendly messaging. Add a try-except block in check_symptoms() (lines 30-33) to handle groq.APIError, network exceptions, and timeout errors, returning a graceful error response instead.

Guard against non-JSON payloads and validate all required fields with proper error status codes.
Line 7 assigns request.json directly, which returns None for invalid or missing JSON payloads. This causes an AttributeError on line 8 when calling .get() on None. Additionally, validation only checks msg but ignores s_id and u_id, and returns HTTP 200 instead of 400 for validation failures.

non-JSON payloads by first obtaining the body safely (use
request.get_json(silent=True) or check request.is_json) and handle None before
accessing .get(); validate that s_id, u_id, and msg are present and non-empty,
and if any are missing return jsonify({"error": "missing fields", "missing":
[...]}) with a 400 status code instead of 200; finally pass the validated s_id,
u_id, msg into check_symptoms and keep using jsonify for the success response.
Ensure you update references to data, s_id, u_id, and msg in this route so no
.get() is called on None and that validation failures return HTTP 400.

Add error handling for external AI service failures.
The check_symptoms() call makes an external Groq API request that can fail due to network issues, authentication errors, or rate limits. Without error handling, these failures return unstructured 500 responses. Wrap the call in a try-except block and map failures to appropriate HTTP status codes (e.g., 502 for unavailable service, 503 for rate limiting) to improve API reliability and provide meaningful feedback to clients.

In `@services/routes/symptoms_route.py` around lines 13 - 14, Wrap the external
call to check_symptoms in the symptoms_route handler with a try/except that
catches network/HTTP/auth/rate-limit errors from the Groq client and returns
structured JSON responses with appropriate status codes; for
transient/unavailable service errors return a 502 with a message, for rate-limit
errors return a 503 (or inspect the exception for 429 and return 429), and for
unexpected exceptions return a 500—include the error message in the JSON body
for debugging and ensure you still return via jsonify({"reply": ...}) or
jsonify({"error": ...}), using the Flask response tuple (body, status_code) to
set the HTTP status.
