MLA 023 Code AI Models & Modes

Description:

Claude Code is the most extensible agentic platform due to its hierarchical memory and deterministic hooks, distinguishing it from IDE-centric competitors like Cursor and Antigravity. While these tools increase developer output by 26%, approximately 45% of AI-generated code contains security vulnerabilities, requiring human review discipline.

Links Market Context

Vibe-coding, a term coined by Andrej Karpathy on February 2, 2025, involves directing software creation via natural language. By 2026, 44% of developers use these tools daily. Anthropic's claude Code drives this shift, contributing to $3 billion in annualized revenue.

Primary Tool Comparison
  • Cursor (Anysphere): VS Code fork with visual editing and background agents. Uses credit-based billing ($20 to $200/month).
  • OpenAI Codex CLI: Rust-based terminal agent using GPT-5.3-Codex. Bundled with ChatGPT Plus ($20/month) and supports network-disabled execution.
  • Google Antigravity: Agent-first IDE built on Gemini 3. Features a Manager View for orchestrating multiple parallel agents.
  • Claude Code: CLI-first platform using Sonnet 4.5 and Opus 4.5/4.6. Known for a composable extensibility model and multi-surface availability (CLI, IDE, Web, Mobile).
Claude Code Architecture
  • Memory (CLAUDE.md): A 4-tier hierarchy (Enterprise, Project, User, Local) that provides persistent context. Supports recursive directory lookups and file imports.
  • Skills: Model-invoked capability packs. claude autonomously loads instructions based on YAML metadata and task relevance to save context.
  • Commands: User-invoked slash commands (e.g., /reset, /review). Users create custom commands via markdown files in .claude/commands.
  • Hooks: Deterministic shell commands or prompts triggered by 12 lifecycle events (e.g., PrePrompt, PostToolUse). Exit code 2 blocks actions, enabling hard enforcement of linting, testing, or security policies.
  • MCP (Model Context Protocol): Open standard connecting claude to external APIs (GitHub, Sentry, Postgres). Tools load on demand to reduce context usage by 95%.
  • Subagents: Specialized workers (General, Plan, Explore) with isolated context windows for delegated tasks.
  • Agent Teams: Experimental multi-session coordination using claude-teams. Independent instances communicate via JSON inbox files.
  • Headless Mode: Using --headless enables CI/CD integration and automated GitHub Actions for code reviews.
Security and Workflow
  • Safety: Local installations use Seatbelt (macOS) or Bubblewrap (Linux) for filesystem and network isolation.
  • Risks: 45% of AI-generated code has security flaws. 10% of apps built with vibe-coding tools show vulnerabilities on initial scans.
  • Best Practice: Use CLAUDE.md for soft guidance and Hooks for hard enforcement. Standard flow follows: Explore -> Plan -> Code -> Commit. Use claude undo to restore state via automatic checkpoints.
