Initialize Claude Code with modern dev-shell-tools for a comfortable development experience.

What This Does

Installs complete dev environment setup:

1. Permissions (.claude/settings.local.json) - Pre-approved CLI tools
2. Rules (.claude/rules/cli-tools.md) - Instructions to prefer modern tools

Tools from dev-shell-tools:

Core Tools:

• Git: Full git access, lazygit, gh (GitHub CLI), delta, difft
• File ops: ls, mkdir, cat, wc, tree, eza, bat, chmod
• Search: rg (ripgrep), fd, fzf, ast-grep/sg
• Navigation: zoxide/z, broot/br
• Data processing: jq, yq, sd, xargs
• Analysis: tokei, procs, hyperfine, dust

Dev Tools:

• Package managers: npm, node, python, uv, pip, brew
• Task runners: just, bash
• Network: curl, http (httpie), firecrawl
• Documentation: tldr
• Windows: powershell

AI CLI Tools:

• gemini: Google Gemini CLI (2M context)
• claude: Anthropic Claude CLI
• codex: OpenAI Codex CLI
• perplexity: Perplexity CLI (web search)

Execution Flow

/init-tools
    |
    +-- Check for existing .claude/ files
    |     +-- If exists: Ask to overwrite or skip
    |     +-- If not: Proceed
    |
    +-- Create .claude directory
    +-- Create .claude/rules directory
    |
    +-- Write settings.local.json (permissions)
    +-- Write rules/cli-tools.md (tool preferences)

Instructions

Step 1: Check for existing settings

ls -la .claude/settings.local.json 2>/dev/null
ls -la .claude/rules/cli-tools.md 2>/dev/null

If files exist, ask user:

• Overwrite: Replace entirely
• Skip: Keep existing, do nothing

Step 2: Create directories

mkdir -p .claude/rules

Step 3: Write permissions file

Write to .claude/settings.local.json:

{
  "permissions": {
    "allow": [
      "Bash(git:*)",
      "Bash(ls:*)",
      "Bash(mkdir:*)",
      "Bash(cat:*)",
      "Bash(wc:*)",
      "Bash(tree:*)",
      "Bash(curl:*)",
      "Bash(rg:*)",
      "Bash(fd:*)",
      "Bash(fzf:*)",
      "Bash(z:*)",
      "Bash(zoxide:*)",
      "Bash(br:*)",
      "Bash(broot:*)",
      "Bash(ast-grep:*)",
      "Bash(sg:*)",
      "Bash(bat:*)",
      "Bash(eza:*)",
      "Bash(delta:*)",
      "Bash(difft:*)",
      "Bash(jq:*)",
      "Bash(yq:*)",
      "Bash(sd:*)",

      "Bash(tldr:*)",
      "Bash(dust:*)",
      "Bash(btm:*)",
      "Bash(bottom:*)",
      "Bash(firecrawl:*)",
      "Bash(gemini:*)",
      "Bash(claude:*)",
      "Bash(codex:*)",
      "Bash(perplexity:*)"
    ],
    "deny": [],
    "ask": [
      "Bash(git reset --hard:*)",
      "Bash(git checkout -- :*)",
      "Bash(git clean -f:*)",
      "Bash(git stash drop:*)",
      "Bash(git stash clear:*)",
      "Bash(git restore --worktree:*)",
      "Bash(git push --force:*)",
      "Bash(git push -f:*)",
      "Bash(git push origin --force:*)",
      "Bash(git push origin -f:*)",
      "Bash(git branch -D:*)"
    ]
  },
  "hooks": {}
}

Step 4: Write rules file

Write to .claude/rules/cli-tools.md:

# CLI Tool Preferences (dev-shell-tools)

ALWAYS prefer modern CLI tools over traditional alternatives.

## File Search & Navigation

| Instead of | Use | Why |
|------------|-----|-----|
| `find` | `fd` | 5x faster, respects .gitignore |
| `grep` | `rg` (ripgrep) | 10x faster, respects .gitignore |
| `ls` | `eza` | Git status, tree view |
| `cat` | `bat` | Syntax highlighting |
| `cd` + manual | `z`/`zoxide` | Frecent directories |
| `tree` | `eza --tree` | Interactive |

## Data Processing

| Instead of | Use |
|------------|-----|
| `sed` | `sd` |
| Manual JSON | `jq` |
| Manual YAML | `yq` |

## Git Operations

| Instead of | Use |
|------------|-----|
| `git diff` | `delta` or `difft` |
| Manual git | `lazygit` |
| GitHub web | `gh` |

## Code Analysis

- Line counts: `tokei`
- AST search: `ast-grep` / `sg`
- Benchmarks: `hyperfine`
- Disk usage: `dust`

## System Monitoring

| Instead of | Use |
|------------|-----|
| `du -h` | `dust` |
| `top`/`htop` | `btm` (bottom) |

## Documentation

| Instead of | Use |
|------------|-----|
| `man <cmd>` | `tldr <cmd>` |

## Python

| Instead of | Use |
|------------|-----|
| `pip` | `uv` |
| `python -m venv` | `uv venv` |

## Task Running

Prefer `just` over Makefiles.

## Web Fetching

| Priority | Tool | When to Use |
|----------|------|-------------|
| 1 | `WebFetch` | First attempt - fast, built-in |
| 2 | `r.jina.ai/URL` | JS-rendered pages, cleaner extraction |
| 3 | `firecrawl <url>` | Anti-bot bypass, blocked sites |

## AI CLI Tools

For multi-model analysis (see /conclave command):

| Tool | Model | Best For |
|------|-------|----------|
| `gemini` | Gemini 2.5 | 2M context, large codebases |
| `claude` | Claude | Coding, analysis |
| `codex` | OpenAI | Deep reasoning |
| `perplexity` | Perplexity | Web search, current info |

## Git Safety

Destructive commands require confirmation (in "ask" list):

| Command | Risk | Safe Alternative |
|---------|------|------------------|
| `git reset --hard` | Loses uncommitted changes | `git stash` first |
| `git checkout -- <file>` | Discards file changes | `git stash` or `git diff` first |
| `git clean -fd` | Deletes untracked files | `git clean -n` (dry run) first |
| `git stash drop` | Permanently deletes stash | Check `git stash list` first |
| `git push --force` | Overwrites remote history | `git push --force-with-lease` |
| `git branch -D` | Deletes unmerged branch | `git branch -d` (safe delete) |

**Before destructive operations:**
1. Check status: `git status`
2. Check for uncommitted changes: `git diff`
3. Consider stashing: `git stash`
4. Use dry-run flags when available

Step 5: Confirm

Report to user:

Initialized Claude Code with dev-shell-tools:

Created:
  .claude/settings.local.json  (51 tool permissions, 11 guardrails)
  .claude/rules/cli-tools.md   (modern tool preferences)

Claude will now:
  - Auto-approve dev-shell-tools commands
  - Prefer fd over find, rg over grep, bat over cat, etc.
  - Use AI CLIs for multi-model analysis
  - Ask before destructive git commands (reset --hard, push --force, etc.)

To customize: edit files in .claude/
To add to git: git add .claude/

Options

Flag	Effect
--force	Overwrite existing without asking
--perms-only	Only install permissions, skip rules
--rules-only	Only install rules, skip permissions
--minimal	Minimal permissions (git, ls, cat, mkdir only)
--full	Add cloud/container tools (docker, kubectl, terraform, etc.)
--no-guardrails	Skip git safety guardrails (empty "ask" list)

Full Template (--full)

Adds to permissions:

"Bash(docker:*)",
"Bash(docker-compose:*)",
"Bash(podman:*)",
"Bash(kubectl:*)",
"Bash(helm:*)",
"Bash(terraform:*)",
"Bash(pulumi:*)",
"Bash(aws:*)",
"Bash(gcloud:*)",
"Bash(az:*)",
"Bash(wrangler:*)",
"Bash(flyctl:*)",
"Bash(railway:*)"

Notes

• Permissions are project-local (don't affect other projects)
• Rules instruct Claude to prefer modern tools
• Global settings in ~/.claude/ still apply
• Changes take effect on next tool use (no restart needed)
