# wrkflw-secrets
Comprehensive secrets management for wrkflw workflow execution. This crate provides secure handling of secrets with support for multiple providers, encryption, masking, and GitHub Actions-compatible variable substitution.
## Features
- **Multiple Secret Providers**: Environment variables, files, HashiCorp Vault, AWS Secrets Manager, Azure Key Vault, Google Cloud Secret Manager
- **Secure Storage**: AES-256-GCM encryption for secrets at rest
- **Variable Substitution**: GitHub Actions-compatible `${{ secrets.* }}` syntax
- **Secret Masking**: Automatic masking of secrets in logs and output with pattern detection
- **Caching**: Optional caching with TTL for performance optimization
- **Rate Limiting**: Built-in protection against secret access abuse
- **Input Validation**: Comprehensive validation of secret names and values
- **Health Checks**: Provider health monitoring and diagnostics
- **Configuration**: Flexible YAML/JSON configuration with environment variable support
- **Thread Safety**: Full async/await support with concurrent access
- **Performance Optimized**: Compiled regex patterns and caching for high-throughput scenarios
## Quick Start
```rust
use wrkflw_secrets::prelude::*;
#[tokio::main]
async fn main() -> SecretResult<()> {
// Create a secret manager with default configuration
let manager = SecretManager::default().await?;
// Set an environment variable
std::env::set_var("GITHUB_TOKEN", "ghp_your_token_here");
// Get a secret
let secret = manager.get_secret("GITHUB_TOKEN").await?;
println!("Token: {}", secret.value());
// Use secret substitution
let mut substitution = SecretSubstitution::new(&manager);
let template = "curl -H 'Authorization: Bearer ${{ secrets.GITHUB_TOKEN }}' https://api.github.com";
let resolved = substitution.substitute(template).await?;
// Mask secrets in logs
let mut masker = SecretMasker::new();
masker.add_secret(secret.value());
let safe_log = masker.mask(&resolved);
println!("Safe log: {}", safe_log);
Ok(())
}
```
## Configuration
### Environment Variables
```bash
# Set default provider
export WRKFLW_DEFAULT_SECRET_PROVIDER=env
# Enable/disable secret masking
export WRKFLW_SECRET_MASKING=true
# Set operation timeout
export WRKFLW_SECRET_TIMEOUT=30
```
### Configuration File
Create `~/.wrkflw/secrets.yml`:
```yaml
default_provider: env
enable_masking: true
timeout_seconds: 30
enable_caching: true
cache_ttl_seconds: 300
providers:
env:
type: environment
prefix: "WRKFLW_SECRET_"
file:
type: file
path: "~/.wrkflw/secrets.json"
vault:
type: vault
url: "https://vault.example.com"
auth:
method: token
token: "${VAULT_TOKEN}"
mount_path: "secret"
```
## Secret Providers
### Environment Variables
The simplest provider reads secrets from environment variables:
```rust
// With prefix
std::env::set_var("WRKFLW_SECRET_API_KEY", "secret_value");
let secret = manager.get_secret_from_provider("env", "API_KEY").await?;
// Without prefix
std::env::set_var("GITHUB_TOKEN", "ghp_token");
let secret = manager.get_secret_from_provider("env", "GITHUB_TOKEN").await?;
```
### File-based Storage
Store secrets in JSON, YAML, or environment files:
**JSON format** (`secrets.json`):
```json
{
"API_KEY": "secret_api_key",
"DB_PASSWORD": "secret_password"
}
```
**Environment format** (`secrets.env`):
```bash
API_KEY=secret_api_key
DB_PASSWORD="quoted password"
GITHUB_TOKEN='single quoted token'
```
**YAML format** (`secrets.yml`):
```yaml
API_KEY: secret_api_key
DB_PASSWORD: secret_password
```
### HashiCorp Vault
```yaml
providers:
vault:
type: vault
url: "https://vault.example.com"
auth:
method: token
token: "${VAULT_TOKEN}"
mount_path: "secret"
```
### AWS Secrets Manager
```yaml
providers:
aws:
type: aws_secrets_manager
region: "us-east-1"
role_arn: "arn:aws:iam::123456789012:role/SecretRole" # optional
```
### Azure Key Vault
```yaml
providers:
azure:
type: azure_key_vault
vault_url: "https://myvault.vault.azure.net/"
auth:
method: service_principal
client_id: "${AZURE_CLIENT_ID}"
client_secret: "${AZURE_CLIENT_SECRET}"
tenant_id: "${AZURE_TENANT_ID}"
```
### Google Cloud Secret Manager
```yaml
providers:
gcp:
type: gcp_secret_manager
project_id: "my-project"
key_file: "/path/to/service-account.json" # optional
```
## Variable Substitution
Support for GitHub Actions-compatible secret references:
```rust
let mut substitution = SecretSubstitution::new(&manager);
// Default provider
let template = "TOKEN=${{ secrets.GITHUB_TOKEN }}";
let resolved = substitution.substitute(template).await?;
// Specific provider
let template = "API_KEY=${{ secrets.vault:API_KEY }}";
let resolved = substitution.substitute(template).await?;
```
## Secret Masking
Automatically mask secrets in logs and output:
```rust
let mut masker = SecretMasker::new();
// Add specific secrets
masker.add_secret("secret_value");
// Automatic pattern detection for common secret types
let log = "Token: ghp_1234567890123456789012345678901234567890";
let masked = masker.mask(log);
// Output: "Token: ghp_***"
```
Supported patterns:
- GitHub Personal Access Tokens (`ghp_*`)
- GitHub App tokens (`ghs_*`)
- GitHub OAuth tokens (`gho_*`)
- AWS Access Keys (`AKIA*`)
- JWT tokens
- Generic API keys
## Encrypted Storage
For sensitive environments, use encrypted storage:
```rust
use wrkflw_secrets::storage::{EncryptedSecretStore, KeyDerivation};
// Create encrypted store
let (mut store, key) = EncryptedSecretStore::new()?;
// Add secrets
store.add_secret(&key, "API_KEY", "secret_value")?;
// Save to file
store.save_to_file("secrets.encrypted").await?;
// Load from file
let loaded_store = EncryptedSecretStore::load_from_file("secrets.encrypted").await?;
let secret = loaded_store.get_secret(&key, "API_KEY")?;
```
## Error Handling
All operations return `SecretResult<T>` with comprehensive error types:
```rust
match manager.get_secret("MISSING_SECRET").await {
Ok(secret) => println!("Secret: {}", secret.value()),
Err(SecretError::NotFound { name }) => {
eprintln!("Secret '{}' not found", name);
}
Err(SecretError::ProviderNotFound { provider }) => {
eprintln!("Provider '{}' not configured", provider);
}
Err(SecretError::AuthenticationFailed { provider, reason }) => {
eprintln!("Auth failed for {}: {}", provider, reason);
}
Err(e) => eprintln!("Error: {}", e),
}
```
## Health Checks
Monitor provider health:
```rust
let health_results = manager.health_check().await;
for (provider, result) in health_results {
match result {
Ok(()) => println!("✓ {} is healthy", provider),
Err(e) => println!("✗ {} failed: {}", provider, e),
}
}
```
## Security Best Practices
1. **Use encryption** for secrets at rest
2. **Enable masking** to prevent secrets in logs
3. **Rotate secrets** regularly
4. **Use least privilege** access for secret providers
5. **Monitor access** through health checks and logging
6. **Use provider-specific authentication** (IAM roles, service principals)
7. **Configure rate limiting** to prevent abuse
8. **Validate input** - the system automatically validates secret names and values
## Rate Limiting
Protect against abuse with built-in rate limiting:
```rust
use wrkflw_secrets::rate_limit::RateLimitConfig;
use std::time::Duration;
let mut config = SecretConfig::default();
config.rate_limit = RateLimitConfig {
max_requests: 100, // Max requests per window
window_duration: Duration::from_secs(60), // 1 minute window
enabled: true,
};
let manager = SecretManager::new(config).await?;
// Rate limiting is automatically applied to all secret access operations
match manager.get_secret("API_KEY").await {
Ok(secret) => println!("Success: {}", secret.value()),
Err(SecretError::RateLimitExceeded(msg)) => {
println!("Rate limited: {}", msg);
}
Err(e) => println!("Other error: {}", e),
}
```
## Input Validation
All inputs are automatically validated:
```rust
// Secret names must:
// - Be 1-255 characters long
// - Contain only letters, numbers, underscores, hyphens, and dots
// - Not start or end with dots
// - Not contain consecutive dots
// - Not be reserved system names
// Secret values must:
// - Be under 1MB in size
// - Not contain null bytes
// - Be valid UTF-8
// Invalid examples that will be rejected:
manager.get_secret("").await; // Empty name
manager.get_secret("invalid/name").await; // Invalid characters
manager.get_secret(".hidden").await; // Starts with dot
manager.get_secret("CON").await; // Reserved name
```
## Performance Features
### Caching
```rust
let config = SecretConfig {
enable_caching: true,
cache_ttl_seconds: 300, // 5 minutes
..Default::default()
};
```
### Optimized Pattern Matching
- Pre-compiled regex patterns for secret detection
- Global pattern cache using `OnceLock`
- Efficient string replacement algorithms
- Cached mask generation
### Benchmarking
Run performance benchmarks:
```bash
cargo bench -p wrkflw-secrets
```
## Feature Flags
Enable optional providers:
```toml
[dependencies]
wrkflw-secrets = { version = "0.1", features = ["vault-provider", "aws-provider"] }
```
Available features:
- `env-provider` (default)
- `file-provider` (default)
- `vault-provider`
- `aws-provider`
- `azure-provider`
- `gcp-provider`
- `all-providers`

//! # wrkflw-secrets
//!
//! Comprehensive secrets management for wrkflw workflow execution.
//! Supports multiple secret providers and secure handling throughout the execution pipeline.
//!
//! ## Features
//!
//! - **Multiple Secret Providers**: Environment variables, file-based storage, with extensibility for cloud providers
//! - **Secret Substitution**: GitHub Actions-style secret references (`${{ secrets.SECRET_NAME }}`)
//! - **Automatic Masking**: Intelligent secret detection and masking in logs and output
//! - **Rate Limiting**: Built-in protection against secret access abuse
//! - **Caching**: Configurable caching for improved performance
//! - **Input Validation**: Comprehensive validation of secret names and values
//! - **Thread Safety**: Full async/await support with thread-safe operations
//!
//! ## Quick Start
//!
//! ```rust
//! use wrkflw_secrets::{SecretManager, SecretMasker, SecretSubstitution};
//!
//! #[tokio::main]
//! async fn main() -> Result<(), Box<dyn std::error::Error>> {
//! // Initialize the secret manager with default configuration
//! let manager = SecretManager::default().await?;
//!
//! // Set an environment variable for testing
//! std::env::set_var("API_TOKEN", "secret_api_token_123");
//!
//! // Retrieve a secret
//! let secret = manager.get_secret("API_TOKEN").await?;
//! println!("Secret value: {}", secret.value());
//!
//! // Use secret substitution
//! let mut substitution = SecretSubstitution::new(&manager);
//! let template = "Using token: ${{ secrets.API_TOKEN }}";
//! let resolved = substitution.substitute(template).await?;
//! println!("Resolved: {}", resolved);
//!
//! // Set up secret masking
//! let mut masker = SecretMasker::new();
//! masker.add_secret("secret_api_token_123");
//!
//! let log_message = "Failed to authenticate with token: secret_api_token_123";
//! let masked = masker.mask(log_message);
//! println!("Masked: {}", masked); // Will show: "Failed to authenticate with token: se***123"
//!
//! // Clean up
//! std::env::remove_var("API_TOKEN");
//! Ok(())
//! }
//! ```
//!
//! ## Configuration
//!
//! ```rust
//! use wrkflw_secrets::{SecretConfig, SecretProviderConfig, SecretManager};
//! use std::collections::HashMap;
//!
//! #[tokio::main]
//! async fn main() -> Result<(), Box<dyn std::error::Error>> {
//! let mut providers = HashMap::new();
//!
//! // Environment variable provider with prefix
//! providers.insert(
//! "env".to_string(),
//! SecretProviderConfig::Environment {
//! prefix: Some("MYAPP_SECRET_".to_string())
//! }
//! );
//!
//! // File-based provider
//! providers.insert(
//! "file".to_string(),
//! SecretProviderConfig::File {
//! path: "/path/to/secrets.json".to_string()
//! }
//! );
//!
//! let config = SecretConfig {
//! default_provider: "env".to_string(),
//! providers,
//! enable_masking: true,
//! timeout_seconds: 30,
//! enable_caching: true,
//! cache_ttl_seconds: 300,
//! rate_limit: Default::default(),
//! };
//!
//! let manager = SecretManager::new(config).await?;
//! Ok(())
//! }
//! ```
//!
//! ## Security Features
//!
//! ### Input Validation
//!
//! All secret names and values are validated to prevent injection attacks and ensure compliance
//! with naming conventions.
//!
//! ### Rate Limiting
//!
//! Built-in rate limiting prevents abuse and denial-of-service attacks on secret providers.
//!
//! ### Automatic Pattern Detection
//!
//! The masking system automatically detects and masks common secret patterns:
//! - GitHub Personal Access Tokens (`ghp_*`)
//! - AWS Access Keys (`AKIA*`)
//! - JWT tokens
//! - API keys and tokens
//!
//! ### Memory Safety
//!
//! Secrets are handled with care to minimize exposure in memory and logs.
//!
//! ## Provider Support
//!
//! ### Environment Variables
//!
//! ```rust
//! use wrkflw_secrets::{SecretProviderConfig, SecretManager, SecretConfig};
//!
//! // With prefix for better security
//! let provider = SecretProviderConfig::Environment {
//! prefix: Some("MYAPP_".to_string())
//! };
//! ```
//!
//! ### File-based Storage
//!
//! Supports JSON, YAML, and environment file formats:
//!
//! ```json
//! {
//! "database_password": "super_secret_password",
//! "api_key": "your_api_key_here"
//! }
//! ```
//!
//! ```yaml
//! database_password: super_secret_password
//! api_key: your_api_key_here
//! ```
//!
//! ```bash
//! # Environment format
//! DATABASE_PASSWORD=super_secret_password
//! API_KEY="your_api_key_here"
//! ```

# wrkflw Secrets Management Demo
This demo demonstrates the comprehensive secrets management system in wrkflw, addressing the critical need for secure secret handling in CI/CD workflows.
## The Problem
Without proper secrets support, workflows are severely limited because:
1. **No way to access sensitive data** - API keys, tokens, passwords, certificates
2. **Security risks** - Hardcoded secrets in code or plain text in logs
3. **Limited usefulness** - Can't integrate with real services that require authentication
4. **Compliance issues** - Unable to meet security standards for production workflows
## The Solution
wrkflw now provides comprehensive secrets management with:
- **Multiple secret providers** (environment variables, files, HashiCorp Vault, AWS Secrets Manager, etc.)
- **GitHub Actions-compatible syntax** (`${{ secrets.* }}`)
- **Automatic secret masking** in logs and output
- **Encrypted storage** for sensitive environments
- **Flexible configuration** for different deployment scenarios
## Quick Start
### 1. Environment Variables (Simplest)
```bash
# Set secrets as environment variables
export GITHUB_TOKEN="ghp_your_token_here"
export API_KEY="your_api_key"
export DB_PASSWORD="secure_password"
```
Create a workflow that uses secrets:
```yaml
# .github/workflows/secrets-demo.yml
name: Secrets Demo
on: [push]
jobs:
test-secrets:
runs-on: ubuntu-latest
steps:
- name: Use GitHub Token
run: |
echo "Using token to access GitHub API"
curl -H "Authorization: Bearer ${{ secrets.GITHUB_TOKEN }}" \
https://api.github.com/user
- name: Use API Key
run: |
echo "API Key: ${{ secrets.API_KEY }}"
- name: Database Connection
env:
DB_PASS: ${{ secrets.DB_PASSWORD }}
run: |
echo "Connecting to database with password: ${DB_PASS}"
```
Run with wrkflw:
```bash
wrkflw run .github/workflows/secrets-demo.yml
```
### 2. File-based Secrets
Create a secrets file:
```json
{
"API_KEY": "your_api_key_here",
"DB_PASSWORD": "secure_database_password",
"GITHUB_TOKEN": "ghp_your_github_token"
}
```
Or environment file format:
```bash
# secrets.env
API_KEY=your_api_key_here
DB_PASSWORD="secure database password"
GITHUB_TOKEN=ghp_your_github_token
```
Configure wrkflw to use file-based secrets:
```yaml
# ~/.wrkflw/secrets.yml
default_provider: file
enable_masking: true
timeout_seconds: 30
providers:
file:
type: file
path: "./secrets.json" # or "./secrets.env"
```
### 3. Advanced Configuration
For production environments, use external secret managers:
```yaml
# ~/.wrkflw/secrets.yml
default_provider: vault
enable_masking: true
timeout_seconds: 30
enable_caching: true
cache_ttl_seconds: 300
providers:
env:
type: environment
prefix: "WRKFLW_SECRET_"
vault:
type: vault
url: "https://vault.company.com"
auth:
method: token
token: "${VAULT_TOKEN}"
mount_path: "secret"
aws:
type: aws_secrets_manager
region: "us-east-1"
role_arn: "arn:aws:iam::123456789012:role/SecretRole"
```
## Secret Providers
### Environment Variables
**Best for**: Development and simple deployments
```bash
# With prefix
export WRKFLW_SECRET_API_KEY="your_key"
export WRKFLW_SECRET_DB_PASSWORD="password"
# Direct environment variables
export GITHUB_TOKEN="ghp_token"
export API_KEY="key_value"
```
Use in workflows:
```yaml
steps:
- name: Use prefixed secret
run: echo "API: ${{ secrets.env:API_KEY }}"
- name: Use direct secret
run: echo "Token: ${{ secrets.GITHUB_TOKEN }}"
```
### File-based Storage
**Best for**: Local development and testing
Supports multiple formats:
**JSON** (`secrets.json`):
```json
{
"GITHUB_TOKEN": "ghp_your_token",
"API_KEY": "your_api_key",
"DATABASE_URL": "postgresql://user:pass@localhost/db"
}
```
**YAML** (`secrets.yml`):
```yaml
GITHUB_TOKEN: ghp_your_token
API_KEY: your_api_key
DATABASE_URL: postgresql://user:pass@localhost/db
```
**Environment** (`secrets.env`):
```bash
GITHUB_TOKEN=ghp_your_token
API_KEY=your_api_key
DATABASE_URL="postgresql://user:pass@localhost/db"
```
### HashiCorp Vault
**Best for**: Production environments with centralized secret management
```yaml
providers:
vault:
type: vault
url: "https://vault.company.com"
auth:
method: token
token: "${VAULT_TOKEN}"
mount_path: "secret/v2"
```
Use vault secrets in workflows:
```yaml
steps:
- name: Use Vault secret
run: curl -H "X-API-Key: ${{ secrets.vault:api-key }}" api.service.com
```
### AWS Secrets Manager
**Best for**: AWS-native deployments
```yaml
providers:
aws:
type: aws_secrets_manager
region: "us-east-1"
role_arn: "arn:aws:iam::123456789012:role/SecretRole"
```
### Azure Key Vault
**Best for**: Azure-native deployments
```yaml
providers:
azure:
type: azure_key_vault
vault_url: "https://myvault.vault.azure.net/"
auth:
method: service_principal
client_id: "${AZURE_CLIENT_ID}"
client_secret: "${AZURE_CLIENT_SECRET}"
tenant_id: "${AZURE_TENANT_ID}"
```
## Secret Masking
wrkflw automatically masks secrets in logs to prevent accidental exposure:
```bash
# Original log:
# "API response: {\"token\": \"ghp_1234567890abcdef\", \"status\": \"ok\"}"
# Masked log:
# "API response: {\"token\": \"ghp_***\", \"status\": \"ok\"}"
```
Automatically detects and masks:
- GitHub Personal Access Tokens (`ghp_*`)
- GitHub App tokens (`ghs_*`)
- GitHub OAuth tokens (`gho_*`)
- AWS Access Keys (`AKIA*`)
- JWT tokens
- Generic API keys
## Workflow Examples
### GitHub API Integration
```yaml
name: GitHub API Demo
on: [push]
jobs:
github-integration:
runs-on: ubuntu-latest
steps:
- name: List repositories
run: |
curl -H "Authorization: Bearer ${{ secrets.GITHUB_TOKEN }}" \
-H "Accept: application/vnd.github.v3+json" \
https://api.github.com/user/repos
- name: Create issue
run: |
curl -X POST \
-H "Authorization: Bearer ${{ secrets.GITHUB_TOKEN }}" \
-H "Accept: application/vnd.github.v3+json" \
https://api.github.com/repos/owner/repo/issues \
-d '{"title":"Automated issue","body":"Created by wrkflw"}'
```
### Database Operations
```yaml
name: Database Demo
on: [push]
jobs:
database-ops:
runs-on: ubuntu-latest
steps:
- name: Run migrations
env:
DATABASE_URL: ${{ secrets.DATABASE_URL }}
DB_PASSWORD: ${{ secrets.DB_PASSWORD }}
run: |
echo "Running database migrations..."
# Your migration commands here
- name: Backup database
run: |
pg_dump "${{ secrets.DATABASE_URL }}" > backup.sql
```
### Multi-Provider Example
```yaml
name: Multi-Provider Demo
on: [push]
jobs:
multi-secrets:
runs-on: ubuntu-latest
steps:
- name: Use environment secret
run: echo "Env: ${{ secrets.env:API_KEY }}"
- name: Use file secret
run: echo "File: ${{ secrets.file:GITHUB_TOKEN }}"
- name: Use Vault secret
run: echo "Vault: ${{ secrets.vault:database-password }}"
- name: Use AWS secret
run: echo "AWS: ${{ secrets.aws:prod/api/key }}"
```
## Security Best Practices
### 1. Use Appropriate Providers
- **Development**: Environment variables or files
- **Staging**: File-based or simple vault
- **Production**: External secret managers (Vault, AWS, Azure, GCP)
### 2. Enable Secret Masking
Always enable masking in production:
```yaml
enable_masking: true
```
### 3. Rotate Secrets Regularly
Use secret managers that support automatic rotation:
```yaml
providers:
aws:
type: aws_secrets_manager
region: "us-east-1"
# AWS Secrets Manager handles automatic rotation
```
### 4. Use Least Privilege
Grant minimal necessary permissions:
```yaml
providers:
vault:
type: vault
auth:
method: app_role
role_id: "${VAULT_ROLE_ID}"
secret_id: "${VAULT_SECRET_ID}"
# Role has access only to required secrets
```
### 5. Monitor Secret Access
Use secret managers with audit logging:
```yaml
providers:
azure:
type: azure_key_vault
vault_url: "https://myvault.vault.azure.net/"
# Azure Key Vault provides detailed audit logs
```
## Troubleshooting
### Secret Not Found
```bash
Error: Secret 'API_KEY' not found
# Check:
1. Secret exists in the provider
2. Provider is correctly configured
3. Authentication is working
4. Correct provider name in ${{ secrets.provider:name }}
```
### Authentication Failed
```bash
Error: Authentication failed for provider 'vault'
# Check:
1. Credentials are correct
2. Network connectivity to secret manager
3. Permissions for the service account
4. Token/credential expiration
```
### Secret Masking Not Working
```bash
# Secrets appearing in logs
# Check:
1. enable_masking: true in configuration
2. Secret is properly retrieved (not hardcoded)
3. Secret matches known patterns for auto-masking
```
## Migration Guide
### From GitHub Actions
Most GitHub Actions workflows work without changes:
```yaml
# This works directly in wrkflw
steps:
- name: Deploy
env:
API_TOKEN: ${{ secrets.API_TOKEN }}
run: deploy.sh
```
### From Environment Variables
```bash
# Before (environment variables)
export API_KEY="your_key"
./script.sh
# After (wrkflw secrets)
# Set in secrets.env:
# API_KEY=your_key
# Use in workflow:
# ${{ secrets.API_KEY }}
```
### From CI/CD Platforms
Most secrets can be migrated by:
1. Exporting from current platform
2. Importing into wrkflw's chosen provider
3. Updating workflow syntax to `${{ secrets.NAME }}`
## Performance Considerations
### Caching
Enable caching for frequently accessed secrets:
```yaml
enable_caching: true
cache_ttl_seconds: 300 # 5 minutes
```
### Connection Pooling
For high-volume deployments, secret managers support connection pooling:
```yaml
providers:
vault:
type: vault
# Vault client automatically handles connection pooling
```
### Timeout Configuration
Adjust timeouts based on network conditions:
```yaml
timeout_seconds: 30 # Increase for slow networks
```
## Conclusion
With comprehensive secrets management, wrkflw is now suitable for production workflows requiring secure access to:
- External APIs and services
- Databases and storage systems
- Cloud provider resources
- Authentication systems
- Deployment targets
The flexible provider system ensures compatibility with existing secret management infrastructure while providing a GitHub Actions-compatible developer experience.
**The usefulness limitation has been removed** - wrkflw can now handle real-world CI/CD scenarios securely and efficiently.
