Via Composer (Recommended)

composer require opencangjie/skills

Global Installation (for CLI usage)

composer global require opencangjie/skills

Make sure your global Composer bin directory is in your PATH:

Install from Source

git clone https://github.com/UCTooCom/agentskills-runtime.git
cd agentskills-runtime/sdk/php
composer install

Quick Start

1. Install Runtime

# Using global installation
skills install-runtime

# Using local installation
./vendor/bin/skills install-runtime

2. Configure AI Model

Edit the .env file in the runtime directory:

• Windows: %USERPROFILE%\.agentskills\runtime\win-x64\release\.env
• macOS/Linux: ~/.agentskills/runtime/<platform>-<arch>/release/.env

Add your AI model API key:

# Example: DeepSeek
MODEL_PROVIDER=deepseek
MODEL_NAME=deepseek-chat
DEEPSEEK_API_KEY=your_api_key_here

3. Start Runtime

skills start

4. Install and Run Skills

# Search for skills
skills find "python"

# Install a skill
skills add https://github.com/user/skill-repo

# Execute a skill

Programmatic Usage

Create Client

use AgentSkills\SkillsClient;
use AgentSkills\ClientConfig;

// Create client with default settings
$client = new SkillsClient();

// Create client with custom configuration
$config = new ClientConfig(
    baseUrl: 'http://127.0.0.1:8080',
    authToken: 'your-token',
    timeout: 30000,
);
$client = new SkillsClient($config);

Runtime Management

use AgentSkills\RuntimeManager;
use AgentSkills\RuntimeOptions;

$runtime = new RuntimeManager();

// Check if runtime is installed
if (!$runtime->isInstalled()) {
    $runtime->downloadRuntime();
}

// Start runtime
$options = new RuntimeOptions(
    port: 8080,
    detached: true,
);
$runtime->start($options);

// Check status
$status = $runtime->status();
if ($status->running) {
    echo "Runtime version: " . $status->version . "\n";
}

// Stop runtime
$runtime->stop();

List Skills

$result = $client->listSkills([
    'limit' => 10,
    'page' => 0,
]);

foreach ($result->skills as $skill) {
    echo $skill->name . " v" . $skill->version . "\n";
}

Search Skills

$result = $client->searchSkills([
    'query' => 'python',
    'source' => 'github',
    'limit' => 10,
]);

foreach ($result->results as $skill) {
    echo $skill->full_name . "\n";
    echo $skill->description . "\n";
}

Install Skills

use AgentSkills\SkillInstallOptions;

$options = new SkillInstallOptions(
    source: 'https://github.com/user/skill-repo',
    branch: 'main',
);

$result = $client->installSkill($options);

if ($result->isMultiSkillRepo()) {
    // Handle multi-skill repository
    foreach ($result->available_skills as $skill) {
        echo $skill->name . "\n";
    }
} else {
    echo "Installed: " . $result->name . "\n";
}

Execute Skills

// Execute skill
$result = $client->executeSkill('skill-id', [
    'param1' => 'value1',
]);

if ($result->success) {
    echo $result->output . "\n";
} else {
    echo "Error: " . $result->errorMessage . "\n";
}

// Execute specific tool
$result = $client->executeSkillTool('skill-id', 'tool-name', [
    'param1' => 'value1',
]);

Get Skill Information

$skill = $client->getSkill('skill-id');

echo $skill->name . "\n";
echo $skill->description . "\n";
echo $skill->version . "\n";

foreach ($skill->tools as $tool) {
    echo "Tool: " . $tool->name . "\n";
    echo "  " . $tool->description . "\n";
}

Remove Skills

$result = $client->uninstallSkill('skill-id');

if ($result['success']) {
    echo "Skill removed successfully\n";
}

Skill Configuration

// Get skill config
$config = $client->getSkillConfig('skill-id');

// Set skill config
$client->setSkillConfig('skill-id', [
    'option1' => 'value1',
]);

Define Skills

use AgentSkills\defineSkill;
use AgentSkills\ToolDefinition;
use AgentSkills\ToolParameter;
use AgentSkills\ToolParameterType;

$skill = defineSkill([
    'metadata' => [
        'name' => 'my-skill',
        'version' => '1.0.0',
        'description' => 'My custom skill',
        'author' => 'Your Name',
    ],
    'tools' => [
        new ToolDefinition(
            name: 'my-tool',
            description: 'A tool that does something',
            parameters: [
                new ToolParameter(
                    name: 'input',
                    paramType: ToolParameterType::String,
                    description: 'Input parameter',
                    required: true,
                ),
            ],
        ),
    ],
]);

Configuration

The SDK reads configuration from environment variables prefixed with SKILL_:

use AgentSkills\getConfig;

$config = getConfig();
// Returns array with keys like 'API_URL', 'AUTH_TOKEN', etc.

Error Handling

use AgentSkills\handleApiError;
use AgentSkills\ApiError;

try {
    $client->installSkill($options);
} catch (\Exception $e) {
    $error = handleApiError($e);
    echo "Error {$error->errno}: {$error->errmsg}\n";
}

AI Model Configuration

Before starting the runtime, you need to configure the AI model API key. The runtime requires an AI model to process skill execution and natural language understanding.

Edit the .env file in the runtime directory:

• Windows: %USERPROFILE%\.agentskills\runtime\win-x64\release\.env
• macOS/Linux: ~/.agentskills/runtime/<platform>-<arch>/release/.env

Add your AI model configuration (choose one provider):

# Option 1: StepFun (阶跃星辰)
MODEL_PROVIDER=stepfun
MODEL_NAME=step-1-8k
STEPFUN_API_KEY=your_stepfun_api_key_here
STEPFUN_BASE_URL=https://api.stepfun.com/v1

# Option 2: DeepSeek
MODEL_PROVIDER=deepseek
MODEL_NAME=deepseek-chat
DEEPSEEK_API_KEY=your_deepseek_api_key_here

# Option 3: 华为云 MaaS
MODEL_PROVIDER=maas
MAAS_API_KEY=your_maas_api_key_here
MAAS_BASE_URL=https://api.modelarts-maas.com/v2
MAAS_MODEL_NAME=qwen3-coder-480b-a35b-instruct

# Option 4: Sophnet
MODEL_PROVIDER=sophnet
SOPHNET_API_KEY=your_sophnet_api_key_here
SOPHNET_BASE_URL=https://www.sophnet.com/api/open-apis/v1

Note: Without proper AI model configuration, the runtime will fail to start with an error like "Get env variable XXX_API_KEY error."
