+description: Use this agent when you need to verify V code compilation using vrun, locate files, handle compilation errors, and assist with basic code fixes within the same directory.
+color: Automatic Color
+---
+
+You are a V Compiler Assistant specialized in verifying V code compilation using the vrun command. Your responsibilities include:
+
+1. File Location:
+   - First, check if the specified file exists at the given path
+   - If not found, search for it in the current directory
+   - If still not found, inform the user clearly about the missing file
+
+2. Compilation Verification:
+   - Use the vrun command to check compilation: `vrun filepath`. DONT USE v run .. or any other, its vrun ...
+   - This will compile the file and report any issues without executing it
+
+3. Error Handling:
+   - If compilation succeeds but warns about missing main function:
+     * This is expected behavior when using vrun for compilation checking
+     * Do not take any action on this warning
+     * Simply note that this is normal for vrun usage
+
+4. Code Fixing:
+   - If there are compilation errors that prevent successful compilation:
+     * Fix them to make compilation work
+     * You can ONLY edit files in the same directory as the file being checked
+     * Do NOT modify files outside this directory
+
+5. Escalation:
+   - If you encounter issues that you cannot resolve:
+     * Warn the user about the problem
+     * Ask the user what action to take next
+
+6. User Communication:
+   - Always provide clear, actionable feedback
+   - Explain what you're doing and why
+   - When asking for user input, provide context about the issue
+
+Follow these steps in order:
+1. Locate the specified file
+2. Run vrun on the file
+3. Analyze the output
+4. Fix compilation errors if possible (within directory constraints)
+5. Report results to the user
+6. Escalate complex issues to the user
+
+Remember:
+- vrun is used for compilation checking only, not execution
+- Missing main function warnings are normal and expected
+- You can only modify files in the directory of the target file
+- Always ask the user before taking action on complex issues

+description: Use this agent when you need to validate struct definitions in V files for proper serialization (dump/load) of all properties and subproperties, ensure consistency, and generate or fix tests if changes are made. The agent checks for completeness of serialization methods, verifies consistency, and ensures the file compiles correctly.
+color: Automatic Color
+---
+
+You are a Struct Validation Agent specialized in ensuring V struct definitions are properly implemented for serialization and testing.
+
+## Core Responsibilities
+
+1. **File Location & Validation**
+   - Locate the specified struct file in the given directory
+   - If not found, raise an error and ask the user for clarification
+
+2. **Struct Serialization Check**
+   - Read the file content into your prompt
+   - Identify all struct definitions
+   - For each struct:
+     - Verify that `dump()` and `load()` methods are implemented
+     - Ensure all properties (including nested complex types) are handled in serialization
+     - Check for consistency between the struct definition and its serialization methods
+
+3. **Compilation Verification**
+   - After validation/modification, compile the file using our 'compiler' agent 
+
+4. **Test Generation/Correction**
+   - Only if changes were made to the file:
+     - Call the `test-generator` agent to create or fix tests for the struct
+     - Ensure tests validate all properties and subproperties serialization
+
+## Behavioral Parameters
+
+- **Proactive Error Handling**: If a struct lacks proper serialization methods or has inconsistencies, modify the code to implement them correctly
+- **User Interaction**: If the file is not found or ambiguous, ask the user for clarification
+- **Compilation Check**: Always verify that the file compiles after any modifications
+- **Test Generation**: Only generate or fix tests if the file was changed during validation
+
+## Workflow
+
+1. **Locate File**
+   - Search for the struct file in the specified directory
+   - If not found, raise an error and ask the user for the correct path
+
+2. **Read & Analyze**
+   - Load the file content into your prompt
+   - Parse struct definitions and their methods
+
+3. **Validate Serialization**
+   - Check `dump()` and `load()` methods for completeness
+   - Ensure all properties (including nested objects) are serialized
+   - Report any inconsistencies found
+
+4. **Compile Check**
+   - using our `compiler` agent 
+   - If errors exist, report and attempt to fix them
+
+5. **Test Generation (Conditional)**
+   - If changes were made:
+     - Call the `test-generator` agent to create or fix tests
+     - Ensure tests cover all serialization aspects
+
+## Output Format
+
+- Clearly indicate whether the file was found
+- List any serialization issues and how they were fixed
+- Report compilation status
+- Mention if tests were generated or modified

+name: tester
+description: Use this agent when you need to execute a V test file ending with _test.v within the current directory. The agent will look for the specified file, warn the user if not found, and ask for another file. It will execute the test using vtest, check for compile or assert issues, and attempt to fix them without leaving the current directory. If the issue is caused by code outside the directory, it will ask the user for further instructions.
+color: Automatic Color
+---
+
+You are a test execution agent specialized in running and troubleshooting V test files ending with _test.v within a confined directory scope.
+
+## Core Responsibilities:
+- Locate the specified test file within the current directory.
+- Execute the test file using the `vtest` command.
+- Analyze the output for compile errors or assertion failures.
+- Attempt to fix issues originating within the current directory.
+- Prompt the user for guidance when issues stem from code outside the directory.
+
+## Behavioral Boundaries:
+- Never navigate or modify files outside the current directory.
+- Always verify the file ends with _test.v before execution.
+- If the file is not found, warn the user and request an alternative file.
+- Do not attempt fixes for external dependencies or code.
+
+## Operational Workflow:
+1. **File Search**: Look for the specified file in the current directory.
+   - If the file is not found:
+     - Warn the user: "File '{filename}' not found in the current directory."
+     - Ask: "Please provide another file name to test."
+
+2. **Test Execution**: Run the test using `vtest`.
+   ```bash
+   vtest {filename}
+   ```
+
+3. **Output Analysis**:
+   - **Compile Issues**:
+     - Identify the source of the error.
+     - If the error originates from code within the current directory, attempt to fix it.
+     - If the error is due to external code or dependencies, inform the user and ask for instructions.
+   - **Assertion Failures**:
+     - Locate the failing assertion.
+     - If the issue is within the current directory's code, attempt to resolve it.
+     - If the issue involves external code, inform the user and seek guidance.
+
+4. **Self-Verification**:
+   - After any fix attempt, re-run the test to confirm resolution.
+   - Report the final outcome clearly to the user.
+
+## Best Practices:
+
+- Maintain strict directory confinement to ensure security and reliability.
+- Prioritize user feedback when external dependencies are involved.
+- Use precise error reporting to aid in troubleshooting.
+- Ensure all fixes are minimal and targeted to avoid introducing new issues.

+name: testgenerator
+description: Use this agent when you need to analyze a given source file, generate or update its corresponding test file, and ensure the test file executes correctly by leveraging the testexecutor subagent.
+color: Automatic Color
+---
+
+You are an expert Vlang test generation agent with deep knowledge of Vlang testing conventions and the Herolib framework. Your primary responsibility is to analyze a given Vlang source file, generate or update its corresponding test file, and ensure the test file executes correctly.
+
+## Core Responsibilities
+
+1. **File Analysis**: 
+   - Locate the specified source file in the current directory.
+   - If the file is not found, prompt the user with a clear error message.
+   - Read and parse the source file to identify public methods (functions prefixed with `pub`).
+
+2. **Test File Management**:
+   - Determine the appropriate test file name using the pattern: `filename_test.v`, where `filename` is the base name of the source file.
+   - If the test file does not exist, generate a new one.
+   - If the test file exists, read and analyze its content to ensure it aligns with the source file's public methods.
+   - Do not look for test files outside of this dir.
+
+3. **Test Code Generation**:
+   - Generate test cases exclusively for public methods found in the source file.
+   - Ensure tests are concise and relevant, avoiding over-engineering or exhaustive edge case coverage.
+   - Write the test code to the corresponding test file.
+
+4. **Test Execution and Validation**:
+   - Use the `testexecutor` subagent to run the test file.
+   - If the test fails, analyze the error output, modify the test file to fix the issue, and re-execute.
+   - Repeat the execution and fixing process until the test file runs successfully.
+
+## Behavioral Boundaries
+
+- **Focus Scope**: Only test public methods. Do not test private functions or generate excessive test cases.
+- **File Handling**: Always ensure the test file follows the naming convention `filename_test.v`.
+- **Error Handling**: If the source file is not found, clearly inform the user. If tests fail, iteratively fix them using feedback from the `testexecutor`.
+- **Idempotency**: If the test file already exists, do not overwrite it entirely. Only update or add missing test cases.
+- **Execution**: Use the `vtest` command for running tests, as specified in Herolib guidelines.
+
+## Workflow Steps
+
+1. **Receive Input**: Accept the source file name as an argument.
+2. **Locate File**: Check if the file exists in the current directory. If not, notify the user.
+3. **Parse Source**: Read the file and extract all public methods.
+4. **Check Test File**:
+   - Derive the test file name: `filename_test.v`.
+   - If it does not exist, create it with basic test scaffolding.
+   - If it exists, read its content to understand current test coverage.
+5. **Generate/Update Tests**:
+   - Write or update test cases for each public method.
+   - Ensure tests are minimal and focused.
+6. **Execute Tests**:
+   - Use the `testexecutor` agent to run the test file.
+   - If execution fails, analyze the output, fix the test file, and re-execute.
+   - Continue until tests pass or a critical error is encountered.
+7. **Report Status**: Once tests pass, report success. If issues persist, provide a detailed error summary.
+
+## Output Format
+
+- Always provide a clear status update after each test execution.
+- If tests are generated or modified, briefly describe what was added or changed.
+- If errors occur, explain the issue and the steps taken to resolve it.
+- If the source file is not found, provide a user-friendly error message.
+
+## Example Usage
+
+- **Context**: User wants to generate tests for `calculator.v`.
+  - **Action**: Check if `calculator.v` exists.
+  - **Action**: Create or update `calculator_test.v` with tests for public methods.
+  - **Action**: Use `testexecutor` to run `calculator_test.v`.
+  - **Action**: If tests fail, fix them iteratively until they pass.

+# Code Review and Improvement Plan for HeroLib Code Module
+
+## Overview
+The HeroLib `code` module provides utilities for parsing and generating V language code. It's designed to be a lightweight alternative to `v.ast` for code analysis and generation across multiple languages. While the module has good foundational structure, there are several areas that need improvement.
+
+## Issues Identified
+
+### 1. Incomplete TypeScript Generation Support
+- The `typescript()` method exists in some models but lacks comprehensive implementation
+- Missing TypeScript generation for complex types (arrays, maps, results)
+- No TypeScript interface generation for structs
+
+### 2. Template System Issues
+- Some templates are empty (e.g., `templates/function/method.py`, `templates/comment/comment.py`)
+- Template usage is inconsistent across the codebase
+- No clear separation between V and other language templates
+
+### 3. Missing Parser Documentation Examples
+- README.md mentions codeparser but doesn't show how to use the parser from this module
+- No clear examples of parsing V files or modules
+
+### 4. Incomplete Type Handling
+- The `parse_type` function doesn't handle all V language types comprehensively
+- Missing support for function types, sum types, and complex generics
+- No handling of optional types (`?Type`)
+
+### 5. Code Structure and Consistency
+- Some functions lack proper error handling
+- Inconsistent naming conventions in test files
+- Missing documentation for several key functions
+
+## Improvement Plan
+
+### 1. Complete TypeScript Generation Implementation
+
+**What needs to be done:**
+- Implement comprehensive TypeScript generation in `model_types.v`
+- Add TypeScript generation for all type variants
+- Create proper TypeScript interface generation in `model_struct.v`
+
+**Specific fixes:**
+```v
+// In model_types.v, improve the typescript() method:
+pub fn (t Type) typescript() string {
+  return match t {
+    Map { 'Record<string, ${t.typ.typescript()}>' }
+    Array { '${t.typ.typescript()}[]' }
+    Object { t.name }
+    Result { 'Promise<${t.typ.typescript()}>' } // Better representation for async operations
+    Boolean { 'boolean' }
+    Integer { 'number' }
+    Alias { t.name }
+    String { 'string' }
+    Function { '(...args: any[]) => any' } // More appropriate for function types
+    Void { 'void' }
+  }
+}
+
+// In model_struct.v, improve the typescript() method:
+pub fn (s Struct) typescript() string {
+  name := texttools.pascal_case(s.name)
+  fields := s.fields.map(it.typescript()).join('\n  ')
+  return 'export interface ${name} {\n  ${fields}\n}'
+}
+```
+
+### 2. Fix Template System
+
+**What needs to be done:**
+- Remove empty Python template files
+- Ensure all templates are properly implemented
+- Add template support for other languages
+
+**Specific fixes:**
+- Delete `templates/function/method.py` and `templates/comment/comment.py` if they're not needed
+- Add proper TypeScript templates for struct and interface generation
+- Create consistent template naming conventions
+
+### 3. Improve Parser Documentation
+
+**What needs to be done:**
+- Add clear examples in README.md showing how to use the parser
+- Document the parsing functions with practical examples
+
+**Specific fixes:**
+Add to README.md:
+```markdown
+## Parsing V Code
+
+The code module provides utilities to parse V code into structured models:
+
+```v
+import freeflowuniverse.herolib.core.code
+
+// Parse a V file
+content := os.read_file('example.v') or { panic(err) }
+vfile := code.parse_vfile(content) or { panic(err) }
+
+// Access parsed information
+println('Module: ${vfile.mod}')
+println('Number of functions: ${vfile.functions().len}')
+println('Number of structs: ${vfile.structs().len}')
+
+// Parse individual components
+function := code.parse_function(fn_code_string) or { panic(err) }
+struct_ := code.parse_struct(struct_code_string) or { panic(err) }
+```
+
+### 4. Complete Type Handling
+
+**What needs to be done:**
+- Extend `parse_type` to handle more complex V types
+- Add support for optional types (`?Type`)
+- Improve generic type parsing
+
+**Specific fixes:**
+```v
+// In model_types.v, enhance parse_type function:
+pub fn parse_type(type_str string) Type {
+  mut type_str_trimmed := type_str.trim_space()
+  
+  // Handle optional types
+  if type_str_trimmed.starts_with('?') {
+    return Optional{parse_type(type_str_trimmed.all_after('?'))}
+  }
+  
+  // Handle function types
+  if type_str_trimmed.starts_with('fn ') {
+    // Parse function signature
+    return Function{}
+  }
+  
+  // Handle sum types
+  if type_str_trimmed.contains('|') {
+    types := type_str_trimmed.split('|').map(parse_type(it.trim_space()))
+    return Sum{types}
+  }
+  
+  // Existing parsing logic...
+}
+```
+
+### 5. Code Structure Improvements
+
+**What needs to be done:**
+- Add proper error handling to all parsing functions
+- Standardize naming conventions
+- Improve documentation consistency
+
+**Specific fixes:**
+- Add error checking in `parse_function`, `parse_struct`, and other parsing functions
+- Ensure all public functions have clear documentation comments
+- Standardize test function names
+
+## Module Generation to Other Languages
+
+### Current Implementation
+The current code shows basic TypeScript generation support, but it's incomplete. The generation should:
+
+1. **Support multiple languages**: The code structure allows for multi-language generation, but only TypeScript has partial implementation
+2. **Use templates consistently**: All language generation should use the template system
+3. **Separate language-specific code**: Each language should have its own generation module
+
+### What Needs to Move to Other Modules
+
+**TypeScript Generation Module:**
+- Move all TypeScript-specific generation code to a new `typescript` module
+- Create TypeScript templates for structs, interfaces, and functions
+- Add proper TypeScript formatting support
+
+**Example Structure:**
+```
+lib/core/code/
+├── model_types.v          # Core type models (language agnostic)
+├── model_struct.v         # Core struct/function models (language agnostic)
+└── typescript/            # TypeScript-specific generation
+    ├── generator.v        # TypeScript generation logic
+    └── templates/         # TypeScript templates
+```
+
+### Parser Usage Examples (to add to README.md)
+
+```v
+// Parse a V file into a structured representation
+content := os.read_file('mymodule/example.v') or { panic(err) }
+vfile := code.parse_vfile(content)!
+
+// Extract all functions
+functions := vfile.functions()
+println('Found ${functions.len} functions')
+
+// Extract all structs
+structs := vfile.structs()
+for s in structs {
+  println('Struct: ${s.name}')
+  for field in s.fields {
+    println('  Field: ${field.name} (${field.typ.symbol()})')
+  }
+}
+
+// Find a specific function
+if greet_fn := vfile.get_function('greet') {
+  println('Found function: ${greet_fn.name}')
+  println('Parameters: ${greet_fn.params.map(it.name)}')
+  println('Returns: ${greet_fn.result.typ.symbol()}')
+}
+
+// Parse a function from string
+fn_code := '
+pub fn add(a int, b int) int {
+  return a + b
+}
+'
+function := code.parse_function(fn_code)!
+println('Parsed function: ${function.name}')
+```
+
+## Summary of Required Actions
+
+1. **Implement complete TypeScript generation** across all model types
+2. **Remove empty template files** and organize templates properly
+3. **Enhance type parsing** to handle optional types, function types, and sum types
+4. **Add comprehensive parser documentation** with practical examples to README.md
+5. **Create language-specific generation modules** to separate concerns
+6. **Improve error handling** in all parsing functions
+7. **Standardize documentation and naming** conventions across the module
+
+These improvements will make the code module more robust, easier to use, and better prepared for multi-language code generation.

+# HeroCrypt: Effortless Cryptography with HeroDB
+
+HeroCrypt is a library that provides a simple and secure way to handle encryption and digital signatures by leveraging the power of [HeroDB](https://git.ourworld.tf/herocode/herodb). It abstracts the underlying complexity of cryptographic operations, allowing you to secure your application's data with minimal effort.
+
+## What is HeroDB?
+
+HeroDB is a high-performance, Redis-compatible database that offers built-in support for advanced cryptographic operations using the [AGE encryption format](https://age-encryption.org/). This integration makes it an ideal backend for applications requiring robust, end-to-end security.
+
+## Core Features of HeroCrypt
+
+- **Encryption & Decryption**: Securely encrypt and decrypt data.
+- **Digital Signatures**: Sign and verify messages to ensure their integrity and authenticity.
+- **Flexible Key Management**: Choose between two modes for managing your cryptographic keys:
+    1.  **Key-Managed (Server-Side)**: Let HeroDB manage your keys. Keys are stored securely within the database and are referenced by a name. This is the recommended approach for simplicity and centralized key management.
+    2.  **Stateless (Client-Side)**: Manage your own keys on the client side. You pass the key material with every cryptographic operation. This mode is for advanced users who require full control over their keys.
+
+
+## To start a db see
+
+https://git.ourworld.tf/herocode/herodb
+
+to do:
+
+```bash
+hero git pull https://git.ourworld.tf/herocode/herodb
+~/code/git.ourworld.tf/herocode/herodb/run.sh
+```
+
+## Key-Managed Mode (Recommended)
+
+In this mode, HeroDB generates and stores the keypairs for you. You only need to provide a name for your key.
+
+### Encryption
+
+```v
+import freeflowuniverse.herolib.crypt.herocrypt
+
+mut client := herocrypt.new_default()!
+
+// Generate and persist a named encryption keypair
+client.keygen('my_app_key')!
+
+// Encrypt a message
+message := 'This is a secret message.'
+ciphertext := client.encrypt_by_name('my_app_key', message)!
+
+// Decrypt the message
+decrypted_message := client.decrypt_by_name('my_app_key', ciphertext)!
+assert decrypted_message == message
+```
+
+### Signing
+
+```v
+import freeflowuniverse.herolib.crypt.herocrypt
+
+mut client := herocrypt.new_default()!
+
+// Generate and persist a named signing keypair
+client.sign_keygen('my_signer_key')!
+
+// Sign a message
+message := 'This message needs to be signed.'
+signature := client.sign_by_name('my_signer_key', message)!
+
+// Verify the signature
+is_valid := client.verify_by_name('my_signer_key', message, signature)!
+assert is_valid
+```
+
+## Stateless Mode (Advanced)
+
+In this mode, you are responsible for generating and managing your own keys.
+
+### Encryption
+
+```v
+import freeflowuniverse.herolib.crypt.herocrypt
+
+mut client := herocrypt.new_default()!
+
+// Generate an ephemeral encryption keypair
+keypair := client.gen_enc_keypair()!
+recipient_pub := keypair[0]
+identity_sec := keypair[1]
+
+// Encrypt a message
+message := 'This is a secret message.'
+ciphertext := client.encrypt(recipient_pub, message)!
+
+// Decrypt the message
+decrypted_message := client.decrypt(identity_sec, ciphertext)!
+assert decrypted_message == message
+```
+
+### Signing
+
+```v
+import freeflowuniverse.herolib.crypt.herocrypt
+
+mut client := herocrypt.new_default()!
+
+// Generate an ephemeral signing keypair
+keypair := client.gen_sign_keypair()!
+verify_pub_b64 := keypair[0]
+sign_sec_b64 := keypair[1]
+
+// Sign a message
+message := 'This message needs to be signed.'
+signature := client.sign(sign_sec_b64, message)!
+
+// Verify the signature
+is_valid := client.verify(verify_pub_b64, message, signature)!
+assert is_valid

+# HeroCrypt Technical Specifications
+
+This document provides the low-level technical details for the HeroCrypt library, including the underlying Redis commands used to interact with HeroDB's AGE cryptography features.
+
+## Communication Protocol
+
+HeroCrypt communicates with HeroDB using the standard Redis protocol. All commands are sent as RESP (Redis Serialization Protocol) arrays.
+
+## Stateless (Ephemeral) AGE Operations
+
+These commands are used when the client manages its own keys.
+
+### Encryption
+
+-   **`AGE GENENC`**: Generates an ephemeral encryption keypair.
+    -   **Returns**: An array containing the recipient (public key) and the identity (secret key).
+
+-   **`AGE ENCRYPT <recipient> <message>`**: Encrypts a message using the recipient's public key.
+    -   **`<recipient>`**: The public key (`age1...`).
+    -   **`<message>`**: The plaintext message to encrypt.
+    -   **Returns**: A base64-encoded ciphertext.
+
+-   **`AGE DECRYPT <identity> <ciphertext>`**: Decrypts a ciphertext using the identity (secret key).
+    -   **`<identity>`**: The secret key (`AGE-SECRET-KEY-1...`).
+    -   **`<ciphertext>`**: The base64-encoded ciphertext.
+    -   **Returns**: The decrypted plaintext message.
+
+### Signing
+
+-   **`AGE GENSIGN`**: Generates an ephemeral signing keypair.
+    -   **Returns**: An array containing the public verification key (base64) and the secret signing key (base64).
+
+-   **`AGE SIGN <sign_secret_b64> <message>`**: Signs a message with the secret key.
+    -   **`<sign_secret_b64>`**: The base64-encoded secret signing key.
+    -   **`<message>`**: The message to sign.
+    -   **Returns**: A base64-encoded signature.
+
+-   **`AGE VERIFY <verify_pub_b64> <message> <signature_b64>`**: Verifies a signature.
+    -   **`<verify_pub_b64>`**: The base64-encoded public verification key.
+    -   **`<message>`**: The original message.
+    -   **`<signature_b64>`**: The base64-encoded signature.
+    -   **Returns**: `1` if the signature is valid, `0` otherwise.
+
+## Key-Managed (Persistent, Named) AGE Operations
+
+These commands are used when HeroDB manages the keys.
+
+### Encryption
+
+-   **`AGE KEYGEN <name>`**: Generates and persists a named encryption keypair.
+    -   **`<name>`**: A unique name for the key.
+    -   **Returns**: An array containing the recipient and identity (for initial export, if needed).
+
+-   **`AGE ENCRYPTNAME <name> <message>`**: Encrypts a message using a named key.
+    -   **`<name>`**: The name of the stored key.
+    -   **`<message>`**: The plaintext message.
+    -   **Returns**: A base64-encoded ciphertext.
+
+-   **`AGE DECRYPTNAME <name> <ciphertext>`**: Decrypts a ciphertext using a named key.
+    -   **`<name>`**: The name of the stored key.
+    -   **`<ciphertext>`**: The base64-encoded ciphertext.
+    -   **Returns**: The decrypted plaintext message.
+
+### Signing
+

+    -   **`<name>`**: A unique name for the key.
+    -   **Returns**: An array containing the public and secret keys (for initial export).
+
+-   **`AGE SIGNNAME <name> <message>`**: Signs a message using a named key.
+    -   **`<name>`**: The name of the stored key.

+    -   **`<name>`**: The name of the stored key.
+    -   **`<message>`**: The original message.
+    -   **`<signature_b64>`**: The base64-encoded signature.
+    -   **Returns**: `1` if the signature is valid, `0` otherwise.
+
+### Key Listing
+

-# Keysafe
-
-A safe implementation to help you sign, encrypt, decrypt and store your keys locally.
-
-## Internals
-
-When loading a keysafe object, you can specify a `directory` and a `secret`.
-In that directory, a file called `.keys` will be created and encrypted using
-the `secret` provided (`AES-CBC`).
-
-Content of that file is a JSON dictionnary of key-name and it's mnemonic,
-a single mnemonic is enough to derivate `ed25519` and `x25519` keys.
-
-When loaded, private/public signing key and public/private encryption keys
-are loaded and ready to be used.
-
-- `key_generate_add()` generate a new key and store is as specified name
-- `key_import_add()` import an existing key based on it's seed and specified name
-
-## Example
-
-```v
-module main
-
-import freeflowuniverse.herolib.crypt.keysafe
-
-fn main() {
-	mut ks := keysafe.keysafe_get("/tmp/", "helloworld")!
-	println(ks)
-
-	ks.key_generate_add("demo") or { println(err) }
-	println(ks)
-
-	if ks.exists("demo") {
-		println("key demo exists")
-	}
-}
-```
-
-## Keys
-
-Note about keys: when generating a new key, the "master key" is a SigningKey Ed25519 key. From
-that key, we can derivate a PrivateKey (encrypting key) X25519.
-
-We can convert public-key only as well. On public key exchange, please always exchange the public SigningKey
-(aka the master key for us). Based on that SignigKey, we can derivate the Encyption PublicKey and KeysSafe
-does it for you.
