🧠 TeamHealthBot — Anonymous Slack gRPC Health Check System (Work in Progress 🚧)

TeamHealthBot is an anonymous Slack-integrated health check system designed to make it easier for users to report dysfunctional or unhealthy teams — without pressure, judgment, or retaliation. Each week, users are prompted privately to rate their team from 1–100, with scoring logic designed to encourage honest responses and detect outliers. The scores are processed via a high-performance C++ gRPC microservice, with calculations that factor in deviation, inflation limits, and alignment bonuses to detect anomalies and ensure fairness.

🔧 System Design Overview

🎯 Core Flow:

1. Slack bot sends /teamhealth prompt to all users (via slash command or weekly schedule).
2. Users respond with a score from 1–100 within 5 minutes.
3. Scores are:
   • Cached in Redis (for speed and deduplication)
   • Aggregated by Spring Boot
   • Sent to a C++ gRPC microservice for score normalization.
4. Final team score is computed using:
   • Team average
   • Variance/deviation penalties
   • Inflation caps (to prevent constant 100s)
   • Alignment bonuses (tight clustering gets bonus)
5. Result is logged, stored in PostgreSQL, and can be shown in Slack.

⚙️ How to Run Locally

🧵 1. Start the gRPC C++ Microservice

cd cpp_microservice-gRPC/build
cmake ..
make
./microservice
## 🧮 Score Calculation (via gRPC)```protomessage CalculateScoreRequest { string team_id = 1; map<string, int32> scores = 2;}message CalculateScoreResponse { int32 final_score = 1;}
