Simplify CI workflow configuration by eliminating unnecessary repetition * Fix CI testcontainers integration and verify review fixes are complete (#15) * Initial plan * Verify review fixes are complete and CI passes Co-authored-by: unclesp1d3r <251112+unclesp1d3r@users.noreply.github.com> * fix(ci): Configure Testcontainers for GitHub Actions environment - Add explicit Testcontainers environment variables (TESTCONTAINERS_RYUK_DISABLED, DOCKER_HOST) - Remove duplicate npm-install step (bahmutov/npm-install@v1) - Add Docker verification step to diagnose connectivity issues - Pre-pull Docker images (mongo:7, redis:7-alpine, minio/minio:latest) to avoid timeout issues during test execution This addresses the failing CI checks where integration tests couldn't connect to containerized services. The changes ensure Docker is properly configured and available before running tests with Testcontainers. Co-authored-by: unclesp1d3r <251112+unclesp1d3r@users.noreply.github.com> * fix(backend): Read Redis config from environment at connection time Modified createRedisClient() to read REDIS_HOST, REDIS_PORT, and REDIS_PASSWORD directly from process.env at connection time instead of using the cached config object. This allows integration tests to dynamically set Redis connection parameters after module load when using testcontainers. The config module parses environment variables once at module load time, before tests have a chance to start containers and set env vars. By reading environment variables directly during connection, tests can now override Redis configuration with testcontainer-provided host and port values. This fixes the issue where tests couldn't connect to Redis because the connection was attempting to use the default localhost:6379 instead of the testcontainer's dynamically assigned host and port. Co-authored-by: unclesp1d3r <251112+unclesp1d3r@users.noreply.github.com> * fix(redis): Read Redis config from environment variables for better test container support feat(deps): Add 'just' package as a development dependency --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: unclesp1d3r <251112+unclesp1d3r@users.noreply.github.com> Co-authored-by: UncleSp1d3r <unclesp1d3r@evilbitlabs.io> * feat: Initialize monorepo with backend, Next.js frontend, shared package, CI/CD, and development tooling. * refactor(config): Enhance configuration getters for MongoDB, Redis, and S3 to read environment variables dynamically - Updated MongoDB, Redis, and S3 configuration to use getters that read from process.env, allowing for more flexible environment variable management. - Added tests to verify that configuration defaults and environment variable overrides work as expected. - Introduced a delay in queue closure to ensure all connections are properly terminated before shutdown. * chore(justfile): Update default command to use --choose and add shell configurations - Changed the default command from `--list` to `--choose` for better user interaction. - Added configurations for Windows and Bash shells to enhance cross-platform compatibility. * chore(deps): Remove 'just' package from development dependencies in package-lock.json * feat(justfile): Revamp setup and validation scripts for Unix and Windows - Introduced platform-specific setup and validation recipes in the justfile for Unix and Windows environments. - Enhanced setup scripts to check Node.js version, install dependencies, copy environment files, and start Docker services. - Added validation scripts to ensure the correct environment setup, including checks for Node.js, npm, Docker, and project structure. - Removed outdated shell scripts for setup and validation, consolidating functionality within the justfile for improved maintainability. * feat(config): Enhance environment variable handling for JWT and SESSION secrets - Introduced a secure secret generation function using crypto for JWT and SESSION secrets. - Updated environment variable schema to make JWT_SECRET and SESSION_SECRET optional, with validation for production environments. - Modified the parseEnv function to ensure that missing secrets are generated securely in production, improving security practices. - Adjusted Redis password handling to normalize empty strings to undefined for consistent behavior across configurations. * fix(config): Update Redis password handling to return empty string instead of undefined - Modified the Redis password getter to return an explicitly set empty string from the environment variable instead of normalizing it to undefined. - Updated unit tests to reflect this change, ensuring consistent behavior when handling empty passwords. * feat(prompts): Add new prompts for CI checks, code review, performance tuning, security hardening, and task management - Introduced a comprehensive set of prompts to enhance development workflows, including: - `ci_check.prompt.md`: Guidelines for ensuring code changes pass all CI checks before merging. - `code_review.prompt.md`: Framework for analyzing diffs and applying safe internal fixes while preserving public APIs. - `performance_tuning.prompt.md`: Strategies for analyzing performance and applying micro-optimizations. - `security_hardening.prompt.md`: Best practices for improving security posture through safe edits. - `work_next_task.prompt.md`: Process for managing and executing the next task in the development workflow. - Each prompt includes detailed action workflows, focus categories, and critical requirements to guide developers effectively. * feat(ci): Add ci-check command documentation - Introduced a new markdown file for the ci-check command, providing instructions on how to run it based on the guidelines in .github/prompts/ci_check.prompt.md. This addition enhances developer resources for ensuring code changes pass CI checks before merging. * refactor(config): Simplify environment variable handling for configuration getters - Refactored the configuration getters for JWT_SECRET, SESSION_SECRET, and other environment variables to use destructuring for improved readability and maintainability. - Updated the logic for handling missing JWT and SESSION secrets to ensure secure generation in production environments. - Enhanced the handling of various environment variables (e.g., PORT, API_BASE_URL, MONGODB_URI) to utilize destructured assignments, maintaining consistent behavior across configurations. * feat(justfile): Enhance setup and info commands for cross-platform compatibility - Added Git hooks installation for Windows environments, with a warning if bash is not found. - Improved validation checks to exit on missing dependencies for root, backend, and frontend. - Updated info command to provide environment details for both Unix and Windows platforms. - Introduced minio-console command for Unix and updated the Windows version to handle URL opening more robustly. - Consolidated ci-check command to streamline CI processes. * fix(queue): Improve error handling during queue event closure - Enhanced the error event listener to handle wrapped errors from BullMQ, ensuring proper logging of connection closed messages. - Updated the queue closure process to close events before removing listeners, maintaining the error handler during shutdown to catch connection errors. - Ensured listeners are removed even if closing events fails, improving robustness during shutdown. * test(e2e): Add Playwright configuration and home page tests - Add Playwright configuration with Chrome browser support and HTML reporting - Create home page e2e tests to verify page load and main content visibility - Configure test environment with localhost:3000 base URL and retry logic - Add test-results directory to .prettierignore to exclude test artifacts - Refactor queue error handling to use shared helper function for connection-closed error detection - Improve error suppression during normal shutdown to prevent unhandled errors in tests * chore(.gitignore): Add frontend test results directory to ignore list - Add frontend/test-results/ to .gitignore to exclude test artifacts - Prevents test result files from being tracked in version control - Keeps repository clean by ignoring generated test output directories * chore(justfile): Improve install-hooks for cross-platform support - Added checks for the existence of install-git-hooks.sh - Enhanced error handling for missing scripts in both Unix and Windows environments Signed-off-by: UncleSp1d3r <unclesp1d3r@evilbitlabs.io> * chore(.gitignore): Add Playwright report to ignore list chore(test-results): Remove obsolete .last-run.json file Signed-off-by: UncleSp1d3r <unclesp1d3r@evilbitlabs.io> * chore(frontend): update Jest and Playwright configurations - Add testPathIgnorePatterns to Jest config to exclude specific directories. - Modify Playwright test command for better handling of no tests. - Adjust Playwright config to conditionally include web server settings based on CI environment.

1. First, run `just ci-check` to identify any failures
9+
2. Analyze the output to understand what specific checks are failing. If everything passes, you're done.
10+
3. Make minimal, targeted fixes to address ONLY the failing checks:
11+
- For formatting issues: run `just format`
12+
- For linting issues (ESLint): fix the specific violations reported (rerun with `just lint`)
13+
- For type errors: fix the underlying TypeScript code until `just type-check` succeeds
14+
- For test failures: fix the failing tests or underlying code (verify with `just test`, `just test-backend`, `just test-frontend`, or `just test-integration`)
15+
- For dependency security issues: run `npm audit` and address findings, update dependencies as needed
16+
4. After making fixes, run `just ci-check` again to verify all checks pass
17+
5. If any checks still fail, repeat steps 2-4 until all checks pass
18+
6. Provide a summary of what was fixed and confirm that `just ci-check` now passes completely
19+
20+
Keep changes minimal and focused - only fix what's actually causing the CI failures. Do not make unnecessary refactoring or style changes beyond what's required to pass the checks.

description: Analyze diff, apply safe internal fixes, report results
6+
---
7+
8+
Analyze only the changed files (diff scope) and improve them while preserving public APIs. Focus categories: (1) Code Smells (large/duplicate/complex) (2) Design Patterns (service layer, factory, builder, repository) (3) Best Practices (TypeScript strict mode, project conventions, MERN stack patterns) (4) Readability (naming, structure, cohesion) (5) Maintainability (modularization, clarity, service layer separation) (6) Performance (async/await, MongoDB queries, Redis operations, blocking I/O) (7) Type Safety (strict TypeScript, avoid `any`, proper Zod schemas, Mongoose types) (8) Error Handling (AppError class, structured errors, no silent failures, proper logging with Pino). Context: HashHive = MERN stack, service-layer architecture, project-scoped multi-tenancy, security-first, zero-warnings, memory conscious. Prefer clear + secure over clever.
9+
10+
## ACTION WORKFLOW (MANDATORY)
11+
12+
1. Collect diff file list. 2. Analyze per focus category. 3. Classify each finding: `safe-edit` (apply now), `deferred`, `requires-approval`. 4. Auto-apply only `safe-edit` (mechanical, internal, non-breaking, warning removal, correctness, logging consistency, blocking I/O → async/await, console.log → Pino logger). 5. Run `just lint` then `just test`. On failure: isolate failing hunk, revert it, re-run, document skip. 6. Generate report (summary table, applied edits + rationale, deferred backlog, approval-needed with risks, next-step roadmap). 7. Output unified diff (never commit). If zero safe edits: state "No safe automatic edits applied" and still output full report.
13+
14+
## AUTO-EDIT CONSTRAINTS (STRICT)
15+
16+
- Scope: Only diff-related files
17+
- Gates: Must pass `just lint` + tests
18+
- User Control: Never commit/stage
19+
- Public API: No signature/visibility/export changes
20+
- Validation: Always run quality gates before reporting
21+
22+
## CRITICAL REQUIREMENTS
23+
24+
- Actionable suggestions (code examples when clearer)
25+
- Auto-apply only clearly safe internal fixes
26+
- Prioritize runtime correctness, safety, type rigor, security posture
27+
- Preserve all public APIs (no signature/visibility changes)
28+
- Avoid cleverness; optimize for clarity & maintainability
29+
30+
## REPO RULES (REINFORCED)
31+
32+
Zero warnings (ESLint) | Strict TypeScript (no `any`) | Precise typing | Async/await for I/O | Service-layer architecture | AppError for errors | Zod validation | Project-scoped multi-tenancy | Memory efficient | S3-compatible storage (MinIO) | Path validation | No secrets in logs | JSDoc for all public APIs | Pino logging (no console.log)
33+
34+

35+
36+
## EXECUTION CHECKLIST
37+
38+
1 Diff scan 2 Analyze 3 Classify 4 Safe edits applied 5 Gates pass 6 Report (summary/applied/deferred/approval-needed/roadmap) 7 Output diff. On blocker: report + remediation guidance.
39+
40+
## QUICK REFERENCE MATRIX
41+
42+
Category -> Examples of Safe Edits:
43+
44+
- Smells: remove dead code, split oversized internal function (no visibility change)
45+
- Patterns: introduce small private helper or service method internally
46+
