Cloud AI Coding Agents

Claude Code — Anthropic

Claude Code is Anthropic's agentic coding environment with GitHub Actions integration, launched to general availability in August 2025. It operates across three execution contexts: the Claude.com interface, VS Code integration, and GitHub Actions CI/CD environment.

Setup & GitHub Integration

1. Install the Claude Code GitHub App — grants private repository access via native GitHub App with OAuth authentication.
2. Select target repository — choose the repository from the dropdown (e.g., "vip").
3. Configure model selection — select the desired model (e.g., Opus 4.6) and enable auto-accept edits.
4. Configure coding standards — add a CLAUDE.md file in the repository root to define custom coding standards, conventions, and project-specific instructions.
5. Verify task execution — review completed tasks via the task list view, which shows status indicators and line change counts.

Agentic Capabilities

• Autonomous PR implementation from GitHub issues
• Triage and duplicate elimination across open issues
• CI failure analysis and automatic fix generation
• Code review comment implementation
• Vulnerability scanning and remediation
• Subagent support for parallel task execution

Jules — Google Labs

Jules is Google's flagship autonomous coding agent, launched to general availability in August 2025 after a successful beta phase (40K+ tasks completed, 140K+ code improvements). It operates as an "async development agent" for scoped, well-defined tasks, running in secure Google Cloud VMs.

Setup & GitHub Integration

1. Install the Google Labs Jules GitHub App — install from GitHub Settings > Applications.
2. Grant required permissions — read access to administration and artifact metadata; read and write access to actions, code, issues, and pull requests.
3. Select target repository — open Jules and choose the repository from the session modal (e.g., "evgeny-trushin/vip").
4. Configure repo access — use the "Configure repo access" link to manage which repositories Jules can access.
5. Use Environment Snapshots — save dependency states for reproducible execution.
6. Explore Settings tabs — General, Integrations BETA, MCP BETA, and API Key.
7. (Optional) Jules CLI — configure Jules Tools for terminal-native workflows.
8. (Optional) Public API — use the Jules Public API for third-party integrations.

Agentic Capabilities

• Plan-first workflow: generates a visible execution plan for user approval before modifications
• Autonomous bug fixing from GitHub issues
• Feature implementation from issue descriptions
• Dependency management and version upgrades
• Test execution and validation
• Multimodal input support (text, audio, images for context)
• Audio changelogs for asynchronous status sharing
• Support for empty repositories (can create projects from scratch)
• Reusable environment snapshots for faster execution

Execution Model

Purely asynchronous, backgrounded in a secure Google Cloud VM. The user assigns a task, Jules executes autonomously in an isolated environment, and generates a PR for human review. No interactive participation required. Designed for "scoped tasks" with well-defined acceptance criteria.

GitHub Copilot Coding Agent — Microsoft / GitHub

GitHub Copilot Coding Agent (internally codenamed Project Padawan) is GitHub's native autonomous coding agent, launched in May 2025. It operates directly within the GitHub.com interface and GitHub Actions environment as a Tier 1 Primary Autonomous Agent — distinct from Copilot Agent Mode (local VS Code).

Setup & GitHub Integration

1. Navigate to GitHub Copilot settings — open https://github.com/copilot and ensure a Copilot subscription is active ($10/mo base or $39/mo Pro+).
2. Enable the Copilot Coding Agent feature — activate the Coding Agent capability in the Copilot settings panel.
3. Assign issues to @copilot — trigger autonomous task execution by assigning any GitHub issue to @copilot.
4. Review Actions runner configuration — Copilot executes in an isolated GitHub Actions runner environment automatically — no external VM or approval workflow needed.
5. (Optional) Configure MCP servers — set up Model Context Protocol servers for extended tool access (databases, APIs, custom tools).
6. Set up iterative feedback loops — configure feedback and task refinement workflows for complex multi-step tasks.
7. Verify PR review integration — confirm that Copilot-created pull requests integrate with your existing review workflow.

Platform Reference

GitHub Configuration

GitHub serves as the central orchestration layer for AI coding agents. All primary autonomous agents require GitHub App installation and repository access grants. This section documents the shared foundation that enables Claude Code, ChatGPT Codex, Jules, and GitHub Copilot.

Configuration Steps

1. Authenticate via GitHub — use GitHub Mobile or email fallback to enter sudo mode.
2. Navigate to Installed Apps — go to GitHub Settings > Applications > Installed GitHub Apps.
3. Review installed apps — Google Labs Jules, Claude Code GitHub App, Codex integration, GitHub Copilot.
4. Configure repository access — for each app, select "Only select repositories" (not "All repositories").
5. Choose specific repositories — grant access to targeted repositories (e.g., vip, selfdev, claude-skills-collection).
6. Review permissions — verify each app has appropriate read/write access to administration, artifact metadata, actions, code, issues, and pull requests.
7. Save the configuration.

Authentication Methods

Security Best Practices

• Use selective repository access over blanket "All repositories" (principle of least privilege)
• Private repositories (e.g., vip marked with lock icon) require explicit grant
• Sudo mode protects sensitive configuration changes (re-authentication after inactivity)
• Review installed app permissions periodically
• Consider SOC 2 Type II compliance requirements for enterprise deployments
• For strict data residency: evaluate self-hosted options (OpenHands, Windsurf Enterprise, Cursor local operation)
