deploy

deploy

Deploy the project to a hosting platform.

Arguments

• $1 (optional) — platform name override (e.g., vercel, fly, railway)
• --dry-run — show what would happen without executing

Step 1: Pre-Deploy Checks

Run the verify-clean-git-state micro-component from .claude/prompts/verify-clean-git-state.md.

Run the discover-commands micro-component from .claude/prompts/discover-commands.md.

Check git state:

• Warn if not on the default branch (but allow if user confirms)
• Warn if there are uncommitted changes

Step 2: Detect Platform

1. Vercel — best for Next.js, React, static sites. Free tier available.
2. Railway — best for full-stack apps with databases. Starts at $5/month.
3. Fly.io — best for apps needing global distribution. Free tier for small apps.
4. Netlify — best for static sites and Jamstack. Free tier available.
5. Render — best for background workers and cron jobs. Free tier available.
6. Other — I'll help you set up a Dockerfile for any platform.

Wait for user choice, then guide platform setup (generate config file, install CLI if needed).
</IF>
</ELSE>

## Step 3: Verify CLI Tool

Check if the platform's CLI tool is installed:

| Platform | CLI | Check | Install |
|---|---|---|---|
| Vercel | `vercel` | `vercel --version` | `npm i -g vercel` |
| Netlify | `netlify` | `netlify --version` | `npm i -g netlify-cli` |
| Fly.io | `flyctl` | `flyctl version` | `curl -L https://fly.io/install.sh \| sh` |
| Railway | `railway` | `railway --version` | `npm i -g @railway/cli` |
| Render | — | N/A (git push deploy) | N/A |
| Heroku | `heroku` | `heroku --version` | `brew install heroku/brew/heroku` or `npm i -g heroku` |

<IF condition="CLI not installed">
Show install command and ask user to install. If they can't install, provide manual deployment instructions:
"You can also deploy by pushing to your platform's git remote. Here's how: [platform-specific git push instructions]"
</IF>

## Step 4: Deploy

<IF condition="--dry-run">
Show what would be executed without running it:

Dry run — would execute: Platform: [name] Command: [deploy command] Branch: [current branch] Tests: [pass count]

Stop here.
</IF>

Execute the deployment:

| Platform | Command |
|---|---|
| Vercel | `vercel --prod` (or `vercel` for preview) |
| Netlify | `netlify deploy --prod` |
| Fly.io | `flyctl deploy` |
| Railway | `railway up` |
| Render | `git push render main` |
| Heroku | `git push heroku main` |

Monitor output for:
- Deployment URL (capture and display prominently)
- Build errors (present clearly with suggested fixes)
- Warnings (surface but don't block)

## Step 5: Report

```markdown
## Deployment Complete

**URL:** https://your-app.vercel.app
**Platform:** Vercel
**Branch:** main
**Tests:** 47 passing before deploy

### What Happened
- Built the project successfully
- Deployed to production
- Live at the URL above

### Next Time
Run `/deploy` again to redeploy after changes.

Platform: [name] Error: [error message]

What to Try

• [Specific suggestion based on error]
• [Platform documentation link if known]
• Run /debug-session "[error]" for deeper investigation

</IF>

## Rules

- **Never deploy from a dirty working tree** without explicit user confirmation
- **Never deploy with failing tests** without explicit user confirmation
- **Always show the live URL** after successful deployment
- **Graceful degradation** — if CLI is missing, show manual instructions instead of failing
- **No forced deploys** — if something looks wrong, warn and ask before proceeding
- This skill is READ + BASH only — no file edits. Deployment config generation happens in Step 2 only when no config exists.
