Claude Code's advanced features include hooks for injecting custom logic at agent lifecycle stages, scheduled workflows via /loop and /schedule commands, custom agents defined in .claude/agents/, persistent context through CLAUDE.md and Projects, session state files, model switching, parallel sessions with Git worktrees, and integrated browser testing. These capabilities let developers automate repetitive work, maintain consistency across long sessions, and handle complex development tasks with better efficiency.
Hooks are the standout power feature, letting you run custom logic before tool use or on permission requests. Users configure pre-bash guards to block dangerous commands, format-on-save to auto-format every file edit, pre-compact and post-compact hooks to preserve context across compaction, and StopFailure hooks to log API errors. Scheduled workflows using /loop and /schedule can run on a timer for up to a week, handling jobs like PR babysitting or stale PR cleanup. Custom agents live in .claude/agents/ with restricted tools, specific models, and custom prompts for specialized behavior.
Context and memory management relies on Projects to load multiple files so Claude remixes existing material instead of thinking fresh, CLAUDE.md files that store conventions, architecture decisions, and testing expectations read automatically each session, and state files like plan.md and tasks.md that get reloaded each run to prevent context loss. For workflows, users report starting with a cheaper model like Claude Fable 5 to frame the problem, then switching to Claude Opus 4.8. Git worktrees with the -w flag run dozens of parallel Claude sessions in the same repo, and the desktop app auto-starts a dev server to test builds in a built-in browser.

Claude Code offers a range of advanced features for developers, focusing on enhanced control, efficient context management, and automation. These capabilities allow for more complex workflows and better integration into existing development environments.
Enhanced Control and Automation
Advanced features in Claude Code give users granular control over agent behavior and enable automated workflows.
Hooks: Inject custom logic at various stages of an agent's lifecycle, such as before tool use or upon permission requests, allowing for tailored responses and error handling. "Hooks are the real power feature... pre-bash-guard blocks dangerous commands, format-on-save auto-formats every file edit, pre-compact/post-compact preserves context across compaction, and a StopFailure hook logs API errors for diagnostics."
Scheduled Workflows: Automate tasks and workflows using /loop and /schedule commands, which can run operations on a timer for up to a week, useful for repetitive tasks like PR babysitting or stale PR cleanup. "/loop & /schedule — Auto-run workflows on a timer (up to a week). Great for PR babysitting, Slack feedback loops, stale PR cleanup"
Custom Agents and Models: Define custom agents with specific tools, models, and prompts, enabling specialized behavior and focused task execution. "Define custom agents with restricted tools, specific models, and custom prompts in .claude/agents/"
Context and Memory Management
Efficiently managing context and memory is crucial for Claude Code's performance and accuracy, particularly in large or ongoing projects.
Projects for Fixed Material: Use "Projects" to load multiple files, ensuring Claude remixes existing material rather than generating new ideas, which is ideal for repeated tasks with consistent content. "load 40 files into a Project, every answer remixes those files instead of thinking fresh."
CLAUDE.md for Persistent Context: Utilize CLAUDE.md files to store project conventions, architectural decisions, and testing expectations, which Claude automatically reads at the start of each session to maintain consistency. "investing time in a thorough CLAUDE.md. Project conventions, architecture decisions, testing expectations, common patterns. Claude follows them session after session, which keeps it from drifting during longer tasks."
Session State and Memory Files: Save important session data and learnings into dedicated memory files or handoff.md files, which Claude can reference in future sessions, preventing context loss and reducing token costs. "Biggest unlock for me was saving state to files (plan.md, tasks.md) and reloading each run. Feels like the agent "remembers” without blowing context."
Workflow Optimization
Model Switching for Efficiency: Start a conversation with a cheaper model like Claude Fable 5 to frame the problem, then switch to a more powerful model like Claude Opus 4.8 to continue the thread once the context is established, saving on costs. "frame the problem in Claude Fable 5 (your first prompt matters most), switch to Claude Opus 4.8 to continue the thread."
Parallel Sessions with Git Worktrees: Run multiple Claude sessions in parallel within the same repository using Git worktrees, enabling simultaneous development on different features or branches. "Git worktrees (-w) — Run dozens of parallel Claude sessions in the same repo"
Integrated Browser Testing: Auto-start a development server and test it within a built-in browser through the desktop app, providing a real-time view of what Claude is building. "Desktop app web server testing — Auto-starts your dev server and tests it in a built-in browser"
Do these advanced features address your specific needs for using Claude Code?
Bottom line
Claude Code offers features to streamline development workflows, from planning to testing and collaboration.
FAQ
What are hooks in Claude Code?
Hooks inject custom logic at stages of an agent's lifecycle, such as before tool use or on permission requests. You can use them for pre-bash guards, format-on-save, context preservation across compaction, and logging API errors.
How do I automate tasks in Claude Code?
Use the /loop and /schedule commands to run workflows on a timer for up to a week. They work well for repetitive jobs like PR babysitting, Slack feedback loops, and stale PR cleanup.
How does Claude Code keep context across sessions?
CLAUDE.md stores project conventions, architecture decisions, and testing expectations that Claude reads at the start of each session. You can also save session state to files like plan.md and tasks.md and reload them each run to maintain continuity without blowing context.
Can I run multiple Claude Code sessions at the same time?
Yes. Git worktrees with the -w flag let you run dozens of parallel Claude sessions in the same repository, so you can work on different features or branches simultaneously.
How do I save money using different Claude models?
Start your conversation with a cheaper model like Claude Fable 5 to frame the problem, since the first prompt matters most. Once context is established, switch to a more powerful model like Claude Opus 4.8 to continue the thread.
What is CLAUDE.md used for?
CLAUDE.md stores project conventions, architecture decisions, testing expectations, and common patterns. Claude reads it automatically at the start of each session, which keeps it from drifting during longer tasks.
