Claude Code

Claude Code: Deep Coding at Terminal Velocity \ Anthropic

Claude Code Features​

  1. CLAUDE.md: A project memory file to define custom rules and conventions. Claude reads at the start of every session.
  2. Permissions: Control which tools Claude can and can't use.
  3. Plan Mode: Claude plans before it acts. You can review them before any code changes.
  4. Checkpoints: Automatic snapshots of your project to revert to if something goes wrong.
  5. Skills: Reusable instruction files Claude follows automatically.
  6. Hooks: Run custom shell scripts on lifecycle events like PreToolUse or PostToolUse.
  7. MCP: Connect Claude to any external tools like databases and third-party services.
  8. Plugins: Extend Claude with third-party integrations containing skills, MCPs, and hooks.
  9. Context: Feed Claude what it needs and manage the current context window with /context.
  10. Slash Commands: Create shortcuts for tasks you run often. Type / and pick from your saved commands.
  11. Compaction: Compress long conversations to save tokens.
  12. Subagents: Spawn parallel agents for complex tasks. Divide large multi-step workflows and run them simultaneously.

Commands​

brew install --cask claude-code

claude
claude --login
claude --think
# Print Mode: Runs a one-off task (e.g., "fix tests") and exits.
claude -p "query"
  • /compact: Manually shrinks the conversation history to save tokens while preserving key context.
  • /init: Initializes a CLAUDE.md file in your project to store local coding standards and instructions.
  • /model: Quickly switch between models (e.g., switching to haiku for fast tasks or opus for complex logic).
  • /review: Triggers a code review of your current changes or a specific file.
  • /rewind: (Double-tap Esc or type /rewind) Opens a menu to undo recent code changes or revert the conversation.
  • /mcp: Manages Model Context Protocol servers (connecting Claude to tools like Jira, Slack, or databases).
  • /clear: This wipes the old context
  • /powerup: interactive lessons teaching Claude Code features with animated demos

Monitoring​

  • /cost: It will display a breakdown of Input Tokens, Output Tokens, and Cache Hits/Misses, along with a total USD estimate for the current session.
  • /stats: Displays your current token usage and rate limit status.

GSD​

GSD 2.0​

The original GSD was a collection of markdown prompts installed into ~/.claude/commands/. It relied entirely on the LLM reading those prompts and doing the right thing. That worked surprisingly well — but it had hard limits:

  • No context control. The LLM accumulated garbage over a long session. Quality degraded.
  • No real automation. "Auto mode" was the LLM calling itself in a loop, burning context on orchestration overhead.
  • No crash recovery. If the session died mid-task, you started over.
  • No observability. No cost tracking, no progress dashboard, no stuck detection.

GSD v2 solves all of these because it's not a prompt framework anymore — it's a TypeScript application that controls the agent session.

npm install -g gsd-pi@latest

# From within the project directory
/gsd migrate

# Or specify a path
/gsd migrate ~/projects/my-old-project

/gsd auto

`/gsd` and `/gsd next` # — Step Mode
