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.

⚠️ GitGuardian has uncovered 2 secrets following the scan of your pull request.

Please consider investigating the findings and remediating the incidents. Failure to do so may lead to compromising the associated services or software components.

Since your pull request originates from a forked repository, GitGuardian is not able to associate the secrets uncovered with secret incidents on your GitGuardian dashboard.
Skipping this check run and merging your pull request will create secret incidents on your GitGuardian dashboard.

🔎 Detected hardcoded secrets in your pull request

GitGuardian id	GitGuardian status	Secret	Commit	Filename
-	-	Better Auth Secret	a8c640434a11314afd520949a2b1ddd90881929b	`bash nano apps/sim/.env	View secret
-	-	Generic High Entropy Secret	a8c640434a11314afd520949a2b1ddd90881929b	`bash nano apps/sim/.env	View secret

🛠 Guidelines to remediate hardcoded secrets

1. Understand the implications of revoking this secret by investigating where it is used in your code.
2. Replace and store your secrets safely. Learn here the best practices.
3. Revoke and rotate these secrets.
4. If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.

To avoid such incidents in the future consider

• following these best practices for managing and storing secrets including API keys and other credentials
• install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.
