9 native commands

• /initProject setup

  Scans your codebase and creates a CLAUDE.md with commands, architecture notes, and project conventions.

• /clearContext reset

  Clears the conversation context — use before switching tasks to avoid context bleed between unrelated sessions.

• /modelModel switch

  Switch between Opus, Sonnet, and Haiku mid-session. Use Haiku for fast iteration, Opus for complex architecture decisions.

• /diffReview changes

  Shows a git diff of everything Claude has modified in the current session. Review before committing.

• /reviewCode review

  Ask Claude to review the code it just wrote — catches obvious mistakes before you run it.

• /simplifySimplify output

  Strips over-engineering from Claude's output. Useful when Claude adds abstractions you didn't ask for.

• /mcpMCP management

  Lists active MCP servers and their available tools. Use when debugging why a tool isn't responding.

• /permissionsPermission audit

  Shows what Claude Code is allowed to do in this session. Critical before running in CI/automated contexts.

• /helpQuick reference

  In-session quick reference for all native commands. Faster than docs.anthropic.com when you're mid-task.

6 custom commands (ready-to-paste in .claude/commands/)

• /commit-msgGit workflow

  Generates a conventional commit message from staged changes. Reads git diff, outputs message ready to copy.

• /pr-descGit workflow

  Writes a PR description from your branch commits. Title + summary + test plan. Paste directly into GitHub.

• /merge-fixGit workflow

  Resolves merge conflicts by understanding both sides. Explains what each change does before picking a resolution.

• /review-prGit workflow

  Reviews a PR diff for bugs, security issues, and style violations. Output formatted as inline review comments.

• /write-testCode quality

  Generates unit tests for the function or file at cursor. Detects the test framework already in use.

• /add-typesCode quality

  Adds TypeScript types to untyped JS. Infers types from usage, not just signatures — catches implicit any.
