Skills

Skills are reusable prompt modules. By loading SKILL.md, you can inject domain-specific instructions into a session.

Overview

Reuse domain knowledge as skills.
Share consistent behavior across projects.
Enable or disable skills per session.

In Laravel, use SessionConfig skillDirectories and disabledSkills.

Basic usage

If you set a parent directory in skillDirectories, each SKILL.md in its subdirectories is loaded.

use Revolution\Copilot\Contracts\CopilotSession;
use Revolution\Copilot\Facades\Copilot;
use Revolution\Copilot\Types\SessionConfig;

Copilot::start(function (CopilotSession $session) {
    $response = $session->sendAndWait(prompt: 'Review this diff from a security perspective');

    dump($response->content());
}, config: new SessionConfig(
    skillDirectories: [
        base_path('skills'),
    ],
));

You can also pass the config as an array.

Copilot::run(
    prompt: 'Suggest improvements for this README',
    config: [
        'skillDirectories' => [base_path('skills')],
    ],
);

Disable specific skills

Use disabledSkills to disable selected skills after discovery.

$config = new SessionConfig(
    skillDirectories: [base_path('skills')],
    disabledSkills: ['experimental-feature', 'deprecated-tool'],
);

Directory structure

skills/
├── code-review/
│   └── SKILL.md
└── documentation/
    └── SKILL.md

Point skillDirectories to the parent folder, such as skills/.

`SKILL.md` format

SKILL.md is Markdown. You can optionally include YAML frontmatter.

---
name: code-review
description: Specialized code review capabilities
---

# Code Review Guidelines

When reviewing code, always check for:

1. Security vulnerabilities
2. Performance issues
3. Code style
4. Test coverage

Main frontmatter fields:

name: Skill identifier (used by disabledSkills)
description: Short skill description

If you omit name, the directory name is used.

Combine with custom agents

If you set customAgents[].skills, those skill contents are preloaded when that agent starts.

use Revolution\Copilot\Types\SessionConfig;

$config = new SessionConfig(
    skillDirectories: [base_path('skills/security')],
    customAgents: [
        [
            'name' => 'security-auditor',
            'description' => 'Security-focused code reviewer',
            'prompt' => 'Focus on OWASP Top 10 vulnerabilities',
            'skills' => ['security-scan', 'dependency-check'],
        ],
    ],
);

If you omit skills, no skill content is injected into that agent.

Inspect and manage via RPC

You can discover, enable, and disable skills through RPC.

// Discover skills at server level
$result = Copilot::client()->rpc()->skills()->discover();

// List skills in the session
$session->rpc()->skills()->list();

// Enable/disable a specific skill in the session
$session->rpc()->skills()->enable(['name' => 'security-scan']);
$session->rpc()->skills()->disable(['name' => 'security-scan']);

Best practices

Split skills by domain (skills/security, skills/testing, etc.).
Add both name and description in frontmatter.
Explicitly exclude conflicting instructions with disabledSkills.
Verify each skill alone before combining multiple skills.
