Guide for setup Codemap CLI

1. Determine setup context

Ask the user where they want to store the configuration:

Options:

1. Project level (shared via git) - Configuration tracked in version control, shared with team

   • CLAUDE.md updates go to: ./CLAUDE.md
   • Hook settings go to: ./.claude/settings.json

2. Project level (personal preferences) - Configuration stays local, not tracked in git

   • CLAUDE.md updates go to: ./CLAUDE.local.md
   • Hook settings go to: ./.claude/settings.local.json
   • Verify these files are listed in .gitignore, add them if not

3. User level (global) - Configuration applies to all projects for this user

   • CLAUDE.md updates go to: ~/.claude/CLAUDE.md
   • Hook settings go to: ~/.claude/settings.json

Store the user's choice and use the appropriate paths in subsequent steps.

2. Check if Codemap is already installed

Check whether codemap is installed by running codemap -help.

If not installed, proceed with setup.

3. Load Codemap documentation

Read the following documentation to understand Codemap's capabilities:

• Load https://raw.githubusercontent.com/JordanCoin/codemap/refs/heads/main/README.md to understand what Codemap is and its capabilities

4. Guide user through installation

macOS/Linux (Homebrew)

brew tap JordanCoin/tap && brew install codemap

Windows (Scoop)

scoop bucket add codemap https://github.com/JordanCoin/scoop-codemap
scoop install codemap

5. Verify installation

After installation, verify codemap works:

codemap .

6. Update CLAUDE.md file

Use the path determined in step 1. Once Codemap is successfully installed, update the appropriate CLAUDE.md file with the following content:

## Use Codemap CLI for Codebase Navigation

Codemap CLI is available for intelligent codebase visualization and navigation.

**Required Usage** - You MUST use `codemap --diff --ref master` to research changes different from default branch, and `git diff` + `git status` to research current working state.

### Quick Start

```bash
codemap .                    # Project tree
codemap --only swift .       # Just Swift files
codemap --exclude .xcassets,Fonts,.png .  # Hide assets
codemap --depth 2 .          # Limit depth
codemap --diff               # What changed vs main
codemap --deps .             # Dependency flow

Options

Flag	Description
--depth, -d <n>	Limit tree depth (0 = unlimited)
--only <exts>	Only show files with these extensions
--exclude <patterns>	Exclude files matching patterns
--diff	Show files changed vs main branch
--ref <branch>	Branch to compare against (with --diff)
--deps	Dependency flow mode
--importers <file>	Check who imports a file
--skyline	City skyline visualization
--json	Output JSON

Smart pattern matching - no quotes needed:

• .png - any .png file
• Fonts - any /Fonts/ directory
• *Test* - glob pattern

Diff Mode

See what you're working on:

codemap --diff
codemap --diff --ref develop

if the default branch is not `main`, but instead `master` (or something else) update content accordingly:
 - use `codemap --diff --ref master` instead of regular `codemap --diff`


## 7. Update .gitignore file

Update .gitignore file to include `.codemap/` directory:

```text
.codemap/

8. Test Codemap

Run a quick test to verify everything works:

codemap .
codemap --diff

9. Add hooks to settings file

• Use the settings path determined in step 1. Create the settings file if it doesn't exist and add the following content:

  {
      "hooks": {
          "session-start": "codemap hook session-start && echo 'git diff:' && git diff --stat && echo 'git status:' && git status"
      }
  }
  

  if default branch is not main, but instead master (or something else) update content accordingly:

  • use codemap hook session-start --ref=master instead of regular codemap hook session-start
  • For rest of commands also add --ref=master flag.

• Ask user whether he want to add any other hooks and provide list of options with descriptions. Add hooks that he asks for.

Available Hooks

Command	Trigger	Description
codemap hook session-start	SessionStart	Full tree, hubs, branch diff, last session context
codemap hook pre-edit	PreToolUse (Edit|Write)	Who imports file + what hubs it imports
codemap hook post-edit	PostToolUse (Edit|Write)	Impact of changes (same as pre-edit)
codemap hook prompt-submit	UserPromptSubmit	Hub context for mentioned files + session progress
codemap hook pre-compact	PreCompact	Saves hub state to .codemap/hubs.txt
codemap hook session-stop	SessionEnd	Edit timeline with line counts and stats

Example of file with full hooks configuration

{
  "hooks": {
    "SessionStart": [
      {
        "hooks": [
          {
            "type": "command",
            "command": "codemap hook session-start"
          }
        ]
      }
    ],
    "PreToolUse": [
      {
        "matcher": "Edit|Write",
        "hooks": [
          {
            "type": "command",
            "command": "codemap hook pre-edit"
          }
        ]
      }
    ],
    "PostToolUse": [
      {
        "matcher": "Edit|Write"
