feat: add production-ready security infrastructure and CI/CD pipeline #142
Conversation
- Add comprehensive input validation and sanitization middleware - Implement rate limiting for API endpoints and Discord bot - Configure CORS with environment-aware security policies - Create production Dockerfiles for backend and frontend - Add GitHub Actions CI/CD pipeline with testing and security scanning - Write unit tests for core agent functionality - Add OpenAPI/Swagger API documentation - Update docker-compose for full production stack
WalkthroughThis PR introduces comprehensive production-readiness infrastructure across CI/CD, security middleware, containerization, and testing. It adds GitHub Actions workflows for validation and scanning, implements input validation and rate limiting, creates multi-stage Dockerfiles, and establishes Docker Compose networking with security controls and observability.

Estimated code review effort🎯 4 (Complex) | ⏱️ ~45 minutes Multiple middleware modules contain dense rate-limiting logic with windowing, cleanup mechanisms, and validation rules. Integration across Docker, CI/CD, application setup, and Discord bot requires understanding of distinct control flows. Heterogeneous changes span infrastructure, security, and application logic, each requiring separate reasoning paths. Possibly related PRs

Make rate checks atomic to avoid limit bypass under concurrency.
Concurrent requests can both pass checks and exceed limits. Guard check-and-append with a lock.

In frontend/Dockerfile around line 10 the builder stage runs "npm ci
--only=production" which omits devDependencies needed for the build; remove the

installed before running "npm run build", ensuring the build tools are present

In frontend/Dockerfile around lines 21-23 (and similarly for lines 27-29), the
image assumes a healthcheck tool that may not exist; modify the Dockerfile to
install curl (e.g., apk add --no-cache curl) during build and change the
HEALTHCHECK to use curl -f against the container HTTP endpoint (adjust port to
8080 if you opt to run nginx on 8080). Ensure the curl install step is placed
before the HEALTHCHECK instruction and that the HEALTHCHECK uses an appropriate
exit status (curl -f ... || exit 1); optionally, add Dockerfile changes to
create a non-root user and update nginx.conf to listen on 8080 if you decide to
drop root.

In frontend/nginx.conf around lines 13 to 18, remove the deprecated
X-XSS-Protection header, change Referrer-Policy to
strict-origin-when-cross-origin, and tighten the Content-Security-Policy to a
safer baseline: restrict default-src to 'self', explicitly allow
scripts/styles/images only from trusted sources (e.g., script-src 'self';
style-src 'self' https:; img-src 'self' data:), deny plugins/objects (object-src
'none'), set base-uri 'self' and frame-ancestors 'self', and consider adding
upgrade-insecure-requests; if your app needs inline scripts/styles, replace them
with nonces or hashes rather than using 'unsafe-inline'.

add_header after the return and does not explicitly set Content-Type before
returning; move the add_header directive and explicit Content-Type header (e.g.,
add_header Content-Type "text/plain"; or use default_type text/plain;) to appear
before the return statement so headers are sent, and ensure the return uses the
intended plain-text payload (return 200 "healthy\n";) after those header
directives.

In tests/tests_main.py around lines 80 to 86, the test currently uses the
vacuous assertion validate_session_id(valid_session) in [True, False]; replace
that with a concrete positive assertion assert
validate_session_id(valid_session) is True (or assert
validate_session_id(valid_session)), and add a negative case: create an invalid
session id (e.g., a random string or a malformed UUID like "not-a-uuid" or a
UUID with a non-v4 variant) and assert validate_session_id(invalid_session) is
False to ensure the validator rejects bad IDs.
