Greptile Summary

This PR introduces a comprehensive automated key management system implementing a "find, store, inject, forget" workflow for securely managing API keys and secrets. The system integrates with GitHub Actions to scan for required environment variables, check GitHub repository secrets, fetch missing keys from external sources, store them securely, inject them into configuration files, and clear sensitive data from memory.

Major changes:

• New scripts/key-manager.ts implementing core functionality with KeyManager class
• Configuration file key-manager.config.json defining 13 environment variables with validation patterns
• GitHub Actions workflow .github/workflows/key-manager.yml for automated execution
• Comprehensive documentation suite (5 new docs) covering usage, integration, and examples
• Test suite using Vitest for configuration validation
• Updated README with key management section

Issues found:

• Constructor parameter configPath is unused since config loading happens in init() method
• Extensive use of console.log (69 instances) violates project coding standards requiring createLogger from sim/logger

Confidence Score: 4/5

• This PR is safe to merge with minor fixes recommended
• The implementation is well-architected with comprehensive documentation and security considerations. However, it has a logical error (unused constructor parameter) and style violations (extensive console logging instead of project logger). The core functionality is currently placeholder-based (no actual encryption/external fetching), which is acceptable for initial implementation but should be noted.
• Pay attention to scripts/key-manager.ts - fix unused constructor parameter and replace console logging with project logger

Important Files Changed

Filename	Overview
scripts/key-manager.ts	Adds automated key management system with scan, check, fetch, store, inject, and clear workflow. Contains unused constructor parameter and extensive console logging instead of proper logger.
key-manager.config.json	Configuration file defining 13 required/optional keys with patterns, injection targets, external sources, and security settings. Well-structured and complete.
.github/workflows/key-manager.yml	GitHub Actions workflow for running key manager with proper permissions, environment setup, and security cleanup steps.
scripts/key-manager.test.ts	Basic configuration validation tests. Missing tests for core functionality like scanning, checking secrets, injection, and memory clearing.

1. scripts/key-manager.ts, line 82-86 (link)

   style: Uses console.log extensively throughout the file (69 instances). Project standards require using createLogger from sim/logger with logger.info, logger.warn, logger.error instead of console methods.

   _{Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!}

   Context Used: Context from dashboard - Global coding standards that apply to all files (source)

2. scripts/key-manager.ts, line 67 (link)

   logic: unused parameter - config is loaded in init() instead
