/setup - Install Dependencies

Automatically install all viban dependencies based on the operating system.

Execution Steps

Step 1: Detect OS and Package Manager

# Detect OS
if [[ "$OSTYPE" == "darwin"* ]]; then
    OS="macos"
    PKG_MANAGER="brew"
elif [[ "$OSTYPE" == "linux-gnu"* ]]; then
    OS="linux"
    if command -v apt &> /dev/null; then
        PKG_MANAGER="apt"
    elif command -v dnf &> /dev/null; then
        PKG_MANAGER="dnf"
    elif command -v pacman &> /dev/null; then
        PKG_MANAGER="pacman"
    fi
fi

Report detected OS and package manager to user.

Step 2: Check Existing Dependencies

Check which dependencies are already installed:

command -v zsh &> /dev/null && echo "✓ zsh" || echo "✗ zsh"
command -v python3 &> /dev/null && echo "✓ python3" || echo "✗ python3"
command -v gum &> /dev/null && echo "✓ gum" || echo "✗ gum"
command -v jq &> /dev/null && echo "✓ jq" || echo "✗ jq"
command -v viban &> /dev/null && echo "✓ viban ($(viban --version 2>/dev/null || echo 'not installed'))" || echo "✗ viban"

Step 3: Install Missing Dependencies

For each missing dependency, run the appropriate install command:

macOS (Homebrew)

# Install Homebrew if not present
if ! command -v brew &> /dev/null; then
    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
fi

# Install dependencies
brew install zsh gum jq

Linux (apt - Debian/Ubuntu)

# Install zsh and jq
sudo apt update
sudo apt install -y zsh jq

# Install gum (requires Charm repo)
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://repo.charm.sh/apt/gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/charm.gpg
echo "deb [signed-by=/etc/apt/keyrings/charm.gpg] https://repo.charm.sh/apt/ * *" | sudo tee /etc/apt/sources.list.d/charm.list
sudo apt update
sudo apt install -y gum

Linux (dnf - Fedora/RHEL)

sudo dnf install -y zsh jq

# Install gum
echo '[charm]
name=Charm
baseurl=https://repo.charm.sh/yum/
enabled=1
gpgcheck=1
gpgkey=https://repo.charm.sh/yum/gpg.key' | sudo tee /etc/yum.repos.d/charm.repo
sudo dnf install -y gum

Linux (pacman - Arch)

sudo pacman -S --noconfirm zsh jq gum

Step 4: Install or Update viban CLI + Auto-detect (Parallel)

Run dependency installation in the background while auto-detecting project configuration in parallel:

Background task (install):

npm install -g claude-plugin-viban@latest

Parallel task (auto-detect) — run simultaneously:

Jump to Step 7 (Auto-detect Project Configuration) and start gathering project context while installation proceeds.

Wait for both tasks to complete before continuing to Step 5.

Step 5: Verify Installation

viban help

If successful, show:

╭─────────────────────────────────────╮
│      viban setup complete! 🎉       │
╰─────────────────────────────────────╯

All dependencies installed:
  ✓ zsh
  ✓ python3
  ✓ gum
  ✓ jq
  ✓ viban

You can now use:
  viban              Open TUI board
  viban add "task"   Add a task
  viban list         List all tasks
  /viban:assign      Auto-resolve next issue
  /viban:add         Create structured issue

Tip: Use /viban:sync to integrate with GitHub Issues.
     Run it anytime to set up two-way sync.

Step 6: Workflow Setup Introduction

After dependencies are installed and auto-detection is complete, explain to the user:

╭──────────────────────────────────────────────────╮
│         Workflow Setup (Optional)                │
╰──────────────────────────────────────────────────╯

/viban:assign uses your project's .viban/workflow.md
as the TOP PRIORITY when resolving issues.

Without a workflow, a default process is used:
analyze → implement → verify → ship.
Let's set up a custom workflow for this project now.

Ask the user with AskUserQuestion whether they want to configure a workflow now or skip.

• "Configure workflow" → Continue to Step 7
• "Skip" → End setup

Step 7: Auto-detect Project Configuration

Before interviewing, automatically gather project context. Do NOT ask the user about things you can detect.

7.1 Detect build/test commands:

# Check package.json scripts
[ -f package.json ] && cat package.json | jq '.scripts' 2>/dev/null

# Check for common build systems
[ -f Makefile ] && echo "Makefile found"
[ -f pyproject.toml ] && echo "pyproject.toml found"
[ -f Cargo.toml ] && echo "Cargo.toml found"
[ -f go.mod ] && echo "go.mod found"

Determine the appropriate build/test command from the detected files.

7.2 Detect existing conventions from git history:

# Recent commit messages to infer commit style
git log --oneline -20 2>/dev/null

# Branch naming patterns
git branch -r 2>/dev/null | head -20

7.3 Detect project type and verification methods:

Infer from file structure (e.g. src/components/ = frontend, routes/ or controllers/ = backend API, bin/ = CLI).

Store all detected values internally. These will be used in Step 9 to populate the workflow template without asking the user.

Step 8: Workflow Interview

Ask only what the agent cannot infer on its own. One AskUserQuestion call, 3 questions. Everything else uses smart defaults or auto-detection.

Q1. Pipeline

• header: "Pipeline"
• question: "After /viban:assign, how far should the agent go?"
• options:
  • "Full auto — analyze → implement → commit → PR (review in PR)"
  • "Stop before PR — I'll review the diff first (review in terminal/IDE)"
  • "Stop before commit — I'll review the code first (review in terminal/IDE)"
• multiSelect: false

Q2. Issue Tracker Sync

• header: "Sync"
• question: "Sync issues with an external tracker (GitHub Issues, Jira, Linear, etc.)?"
• options:
  • "Yes — set up two-way sync (issues imported from provider)"
  • "No — auto-number locally (#1, #2, #3...)"
  • "No — but use manual external IDs (e.g. PROJ-42)"
• multiSelect: false
• If user selects "Yes", run viban sync to initialize sync after workflow setup completes.

Q3. Extra Rules

Before asking, show the user what was auto-detected from Step 7:

Detected conventions:
  Commit style:  {e.g. "feat: ...", "fix: ..." (Conventional Commits)}
  Branch naming: {e.g. "feat/*", "fix/*"}
  Build command: {e.g. "npm run build && npm test"}
  Project type:  {e.g. "CLI tool (zsh)"}

Then ask:

• header: "Rules"
• question: "Anything to change or add to the detected conventions above?"
• options:
  • "Looks good, use as-is"
  • "Let me adjust"
• multiSelect: false
• If user selects "Let me adjust", collect free-text.

Defaults for everything else (do NOT ask):

Setting	Default	How to override
Commit/PR conventions	Auto-detected from git log history	Q3 free-text or edit .viban/workflow.md
Analysis depth	Agent decides per issue priority/complexity	Edit .viban/workflow.md
Implementation approach	Agent decides per issue type	Edit .viban/workflow.md
Quality gates	Build/tests pass + manual verification	Edit .viban/workflow.md
Test evidence	Test output logs in PR body	Q3 free-text or edit file
Post-merge	Auto-close issue + delete branch	Edit .viban/workflow.md
Verification method	Auto-detected from project type	Edit .viban/workflow.md

Step 9: Generate .viban/workflow.md

9.1 Create .viban/ directory and update .gitignore

mkdir -p .viban

Add .viban to .gitignore:

• If .gitignore exists but does not contain .viban: append .viban to it
• If .gitignore does not exist: create it with .viban
• If .gitignore already contains .viban: do nothing

if [ -f .gitignore ]; then
    grep -qxF '.viban' .gitignore || echo '.viban' >> .gitignore
else
    echo '.viban' > .gitignore
fi

9.2 Check for existing workflow

If .viban/workflow.md already exists, ask user with AskUserQuestion:

• "A workflow already exists at .viban/workflow.md. What would you like to do?"
• Options: "Overwrite with new interview results" / "Keep existing workflow"
• If user chooses to keep: skip generation and end setup.

9.3 Generate workflow file

Combine auto-detected values (Step 7) with interview answers (Step 8) to write .viban/workflow.md.

Auto-detected values (from Step 7) — do NOT ask user:

Value	Detection Source	Example
Build/test command	package.json, Makefile, Cargo.toml, etc.	npm run build && npm test
Project type	File structure analysis	"Web Frontend (React)"
Verification methods	Inferred from project type	"Browser test (Playwright)" for frontend, "CLI output check" for CLI
Existing commit style	git log --oneline -20	Infer convention from history
Branch naming pattern	git branch -r	feat/*, fix/*

Interview values (from Step 8) — only 3 questions:

Value	Source	Example
Pipeline	Q1	"Full auto" or "Stop before PR"
Issue tracker sync	Q2	"Yes (sync)" or "No (auto)" or "No (manual IDs)"
Extra rules	Q3	User-typed rules or "None"

Workflow generation principles:

• Q1 (Pipeline) determines the entire automation structure — which phases run automatically, where to stop, and whether to create PRs. "Full auto" = no stops + auto PR. "Stop before PR" = auto commit + user creates PR. "Stop before commit" = implement only + user reviews.
• Q2 (Issue tracker sync) determines how issues are managed. "Yes" = run viban sync after setup to import/sync issues from external tracker (GitHub, Jira, Linear, etc.), IDs come from provider. "No — auto-number" = viban auto-assigns #1, #2. "No — manual IDs" = agent asks for an external ID each time and passes --ext-id to viban add. When manual, commits/PRs reference the external ID instead of #N.
• Q3 (Extra rules) is appended verbatim to the Additional Rules section. If user mentions conventions, evidence, CHANGELOG, language, etc., incorporate into the relevant phase.
• Commit/PR conventions are auto-detected from git history (Step 7.2). If the user overrides via Q3, use the user's preference instead.
• Everything else uses smart defaults. Analysis depth, implementation approach, quality gates, verification methods, issue numbering, post-merge — all auto-determined by the agent or set to sensible defaults.
• Use auto-detected values for operational details (commands, tools, paths).
• Write the workflow in concrete, actionable language — not vague principles.

Generated template:

# Issue Resolution Workflow

> Auto-applied by `/viban:assign`. Generated by `/viban:setup` - edit freely.

## Pipeline

{FROM Q1:}
{- "Full auto": "Analyze → Implement → Verify → Build → Commit → PR → Review (fully autonomous)"}
{- "Stop before PR": "Analyze → Implement → Verify → Build → Commit → STOP (user creates PR)"}
{- "Stop before commit": "Analyze → Implement → STOP (user reviews code, then commits)"}

---

## Phase 1: Analyze

The agent determines analysis depth based on issue priority and complexity.

1. Read the issue description via `viban get {id}`
2. Explore codebase — approach chosen by agent based on issue context
3. Identify root cause and estimate scope

### Analysis Checklist
- [ ] Issue description fully understood
- [ ] Affected code located and read
- [ ] Root cause identified (or hypothesis formed)
- [ ] Scope of change estimated

---

## Phase 2: Implement

The agent determines implementation approach based on issue type and priority.

### Testing Requirements
{AUTO_DETECTED from project's test framework}

### Implementation Checklist
- [ ] Changes are focused on the issue scope
- [ ] No unrelated changes mixed in
- [ ] {TESTING_CHECKLIST — based on detected test framework}

{IF Q1 is "Stop before commit":}
### >>> STOP: Present changes to user. Wait for approval before committing.

---

## Phase 3: Verify

Verify the fix works. Build/tests must pass + manual verification.

### Verification Methods
{AUTO_DETECTED based on project type}

### Verification Checklist
- [ ] Fix verified
- [ ] No regressions in adjacent functionality
- [ ] Build and tests passing

---

## Phase 4: Build and Test

```bash
{AUTO_DETECTED build/test command}

If build/test fails: fix errors, return to Phase 3.

---

Phase 5: Ship

Commit Convention

{AUTO_DETECTED from git history — infer format from existing commits. If Q3 overrides, use that instead.}

Branch Convention

{AUTO_DETECTED from existing patterns, or issue-{id} as default}

Pull Request

{FROM Q1:} {- "Full auto": create PR with body template, move issue to review via viban review {id}} {- "Stop before PR": commit and push only, notify user that PR is pending. Run viban review {id}.} {- "Stop before commit": N/A — agent already stopped earlier}

PR Body Template

{AUTO_DETECTED from git history convention. If Q3 overrides, use that instead.}

Ship Checklist

• Rebased on latest main
• All commits follow convention
• viban review {id} executed

---

Issue Management

• Issue tracking: {FROM Q2: "Yes" = synced with external tracker via viban sync, "No — auto-number" = auto-increment (viban default), "No — manual IDs" = ask for external ID via --ext-id flag}
• Test evidence: include test output in PR body
• Post-merge: handled by /viban:approve (merges PR, runs viban done {id}, deletes branch)

---

Additional Rules

{FROM Q3, or "None"}

After writing `.viban/workflow.md`, confirm:

╭──────────────────────────────────────────────────╮ │ Workflow saved to .viban/workflow.md! ✨ │ ╰──────────────────────────────────────────────────╯

.viban/ added to .gitignore /viban:assign will now follow your custom workflow. You can edit .viban/workflow.md anytime to adjust it.

---

## Error Handling

- **Homebrew not found on macOS**: Prompt user to install Homebrew first
- **sudo required on Linux**: Inform user that admin privileges are needed
- **Package manager not found**: Show manual installation instructions
- **npm not found**: Install Node.js first

## CLI Reference

| Command | Description |
|---------|-------------|
| `viban help` | Show help and verify installation |
| `viban add "<title>"` | Add a task |
| `viban list` | List all tasks |
| `viban sync` | Initialize external tracker sync |

## Notes

- This command requires terminal access to run shell commands
- On Linux, sudo password may be required
- All commands are idempotent (safe to run multiple times)
