# /deploy

Deploy the project to its hosting platform. Reads the stack template YAML (`templates/stacks/{stack}.yaml`) for exact deploy config (platform, CLI tools, infra tier, CI/CD, monitoring), detects installed CLI tools, sets up database and environment, pushes code, and verifies deployment is live.

## References

- `templates/principles/dev-principles.md` — CI/CD, secrets, DNS, shared infra rules
- `templates/stacks/*.yaml` — Stack templates with deploy, infra, ci_cd, monitoring fields

> Paths are relative to the skill's plugin root. Search for these files via Glob if not found at expected location.

## When to use

After `/build` has completed all tasks (build stage is complete). This is the deployment engine.

Pipeline: `/build` → **`/deploy`** → `/review`

## MCP Tools (use if available)

- `session_search(query)` — find how similar projects were deployed before
- `project_code_search(query, project)` — find deployment patterns across projects
- `codegraph_query(query)` — check project dependencies and stack

If MCP tools are not available, fall back to Glob + Grep + Read.

## Pre-flight Checks

### 1. Verify build is complete (optional)
- If pipeline state tracking exists (`.solo/states/` directory), check `.solo/states/build`.
- If `.solo/states/` exists but `build` marker is missing: warn "Build may not be complete. Consider running `/build` first."
- If `.solo/states/` does not exist: skip this check and proceed with deployment.

### 2. Detect available CLI tools

Run in parallel — detect what's installed locally:
```bash
vercel --version 2>/dev/null && echo "VERCEL_CLI=yes" || echo "VERCEL_CLI=no"
wrangler --version 2>/dev/null && echo "WRANGLER_CLI=yes" || echo "WRANGLER_CLI=no"
npx supabase --version 2>/dev/null && echo "SUPABASE_CLI=yes" || echo "SUPABASE_CLI=no"
fly version 2>/dev/null && echo "FLY_CLI=yes" || echo "FLY_CLI=no"
sst version 2>/dev/null && echo "SST_CLI=yes" || echo "SST_CLI=no"
gh --version 2>/dev/null && echo "GH_CLI=yes" || echo "GH_CLI=no"
```

Record which tools are available. Use them directly when found — do NOT `npx` if CLI is already installed globally.

### 3. Load project context (parallel reads)
- `CLAUDE.md` — stack name, architecture, deploy platform
- `docs/prd.md` — product requirements, deployment notes
- `docs/workflow.md` — CI/CD policy (if exists)
- `package.json` or `pyproject.toml` — dependencies, scripts
- `fly.toml`, `wrangler.toml`, `sst.config.ts` — platform configs (if exist)
- `docs/plan/*/plan.md` — **active plan** (look for deploy-related phases/tasks)

**Plan-driven deploy:** If the active plan contains deploy phases or tasks (e.g. "deploy Python backend to VPS", "run deploy.sh", "set up Docker on server"), treat those as **primary deploy instructions**. The plan knows the project-specific deploy targets that the generic stack YAML may not cover. Execute plan deploy tasks in addition to (or instead of) the standard platform deploy below.

### 4. Read stack template YAML

Extract the **stack name** from `CLAUDE.md` (look for `stack:` field or tech stack section).

Read the stack template to get exact deploy configuration:

**Search order** (first found wins):
1. `templates/stacks/{stack}.yaml` — relative to this skill's plugin root
2. `.solo/stacks/{stack}.yaml` — user's local overrides (from `/init`)
3. Search via Glob for `**/stacks/{stack}.yaml` in project or parent directories

Extract these fields from the YAML:
- `deploy` — target platform(s): `vercel`, `cloudflare_workers`, `cloudflare_pages`, `fly.io`, `docker`, `app_store`, `play_store`, `local`
- `deploy_cli` — CLI tools and their use cases (e.g. `vercel (local preview, env vars, promote)`)
- `infra` — infrastructure tool and tier (e.g. `sst (sst.config.ts) — Tier 1`)
- `ci_cd` — CI/CD system (e.g. `github_actions`)
- `monitoring` — monitoring/analytics (e.g. `posthog`)
- `database` / `orm` — database and ORM if any (affects migration step)
- `storage` — storage services if any (R2, D1, KV, etc.)
- `notes` — stack-specific deployment notes

**Use the YAML values as the source of truth** for all deploy decisions below. The YAML overrides the fallback tier matrix.

### 5. Detect platform (fallback if no YAML)

If stack YAML was not found, use this fallback matrix:

| Stack | Platform | Tier |
|-------|----------|------|
| `nextjs-supabase` / `nextjs-ai-agents` | Vercel + Supabase | Tier 1 |
| `cloudflare-workers` | Cloudflare Workers (wrangler) | Tier 1 |
| `astro-static` / `astro-hybrid` | Cloudflare Pages (wrangler) | Tier 1 |
| `python-api` | Fly.io (quick) or Pulumi + Hetzner (production) | Tier 2/4 |
| `python-ml` | skip (CLI tool, no hosting needed) | — |
| `ios-swift` | skip (App Store is manual) | — |
| `kotlin-android` | skip (Play Store is manual) | — |

If `$ARGUMENTS` specifies a platform, use that instead of auto-detection or YAML.

**Auto-deploy platforms** (from YAML `deploy` field or fallback):
- `vercel` / `cloudflare_pages` — auto-deploy on push. Push to GitHub is sufficient if project is already linked. Only run manual deploy for initial setup.
- `cloudflare_workers` — `wrangler deploy` needed (no git-based auto-deploy for Workers).
- `fly.io` — `fly deploy` needed.

## Deployment Steps

### Step 1. Git — Clean State + Push

```bash
git status
git log --oneline -5
```

If dirty, commit remaining changes:
```bash
git add -A
git commit -m "chore: pre-deploy cleanup"
```

Ensure remote exists and push:
```bash
git remote -v
git push origin main
```

If no remote, create GitHub repo:
```bash
gh repo create {project-name} --private --source=. --push
```

**For platforms with auto-deploy (Vercel, CF Pages):** pushing to main triggers deployment automatically. Skip manual deploy commands if project is already linked.

### Step 2. Database Setup

**Supabase** (if `supabase/` dir or Supabase deps detected):
```bash
# If supabase CLI available:
supabase db push          # apply migrations
supabase gen types --lang=typescript --local > db/types.ts  # optional: regenerate types
```
If no CLI: guide user to Supabase dashboard for migration.

**Drizzle ORM** (if `drizzle.config.ts` exists):
```bash
npx drizzle-kit push      # push schema to database
npx drizzle-kit generate  # generate migration files (if needed)
```

**D1 (Cloudflare)** (if `wrangler.toml` has D1 bindings):
```bash
wrangler d1 migrations apply {db-name}
```

If database is not configured yet, list what's needed and continue — don't block on it.

### Step 3. Environment Variables

Read `.env.example` or `.env.local.example` to identify required variables.

Generate platform-specific instructions:

**Vercel:**
```bash
# If vercel CLI is available and project is linked:
vercel env ls  # show current env vars

# Guide user:
echo "Set env vars: vercel env add VARIABLE_NAME"
echo "Or via dashboard: https://vercel.com/[team]/[project]/settings/environment-variables"
```

**Cloudflare:**
```bash
wrangler secret put VARIABLE_NAME  # interactive prompt for value
# Or in wrangler.toml [vars] section for non-secret values
```

**Fly.io:**
```bash
fly secrets set VARIABLE_NAME=value
fly secrets list
```

**Do NOT create or modify `.env` files with real secrets.**
List what's needed, let user set values.

### Step 4. Platform Deploy

**Vercel** (if not auto-deploying):
```bash
vercel link          # first time: link to project
vercel               # deploy preview
vercel --prod        # deploy production (after verifying preview)
```

**Cloudflare Workers/Pages:**
```bash
wrangler deploy              # Workers
wrangler pages deploy ./out  # Pages (check build output dir)
```

**Fly.io:**
```bash
fly launch   # first time — creates app, sets region
fly deploy   # subsequent deploys
```

**SST** (if sst.config.ts exists):
```bash
sst deploy --stage prod    # production
sst deploy --stage dev     # staging
```

### Step 5. Verify Deployment

After deployment, verify it actually works:

```bash
# 1. HTTP status check
STATUS=$(curl -s -o /dev/null -w "%{http_code}" https://{deployment-url})

# 2. Check for runtime errors in page body
BODY=$(curl -s https://{deployment-url} | head -200)

# 3. Check Vercel deployment logs for errors
vercel logs --output=short 2>&1 | tail -30
```

**If HTTP status is not 200, or page contains error messages:**
1. Check `vercel env ls` — are all required env vars set on the platform?
2. If env vars missing: add them with `vercel env add NAME production <<< "value"`
3. If env vars set but wrong: `vercel env rm NAME production` then re-add
4. After fixing env vars: redeploy with `vercel --prod --yes`
5. Re-check HTTP status and page content

**Common runtime errors and fixes:**
- "Supabase URL/Key required" → add `NEXT_PUBLIC_SUPABASE_URL` + `NEXT_PUBLIC_SUPABASE_ANON_KEY` to Vercel
- "DATABASE_URL not set" → add `DATABASE_URL` to Vercel
- "STRIPE_SECRET_KEY missing" → add Stripe keys or remove Stripe code if not ready
- Blank page / hydration error → check build logs, may need `vercel --prod` redeploy

**Do NOT output `<solo:done/>` until the live URL returns HTTP 200 and page loads without errors.** If you cannot fix the issue, output `<solo:redo/>` to go back to build. Output pipeline signals ONLY if `.solo/states/` directory exists.

### Step 6. Post-Deploy Log Monitoring

After verifying HTTP 200, **tail production logs** to catch runtime errors that only appear under real conditions (missing env vars, DB connection issues, SSR crashes, API timeouts).

Read the `logs` field from the stack YAML to get platform-specific commands:

**Vercel (Next.js):**
```bash
vercel logs --output=short 2>&1 | tail -50
```
Look for: `Error`, `FUNCTION_INVOCATION_FAILED`, `EDGE_FUNCTION_INVOCATION_FAILED`, `504 GATEWAY_TIMEOUT`, unhandled rejections.

**Cloudflare Workers:**
```bash
wrangler tail --format=pretty 2>&1 | head -100
```
Look for: `Error`, uncaught exceptions, D1 query failures, R2 access errors.

**Cloudflare Pages (Astro):**
```bash
wrangler pages deployment tail --project-name={name} 2>&1 | head -100
```

**Fly.io (Python API):**
```bash
fly logs --app {name} 2>&1 | tail -50
fly status --app {name}
```
Look for: `ERROR`, `CRITICAL`, unhealthy instances, OOM kills, connection refused.

**Supabase Edge Functions (if used):**
```bash
supabase functions logs --scroll 2>&1 | tail -30
```

**What to do with log errors:**
- **Env var missing** → fix with platform CLI (see Step 3), redeploy
- **DB connection error** → check connection string, IP allowlist
- **Runtime crash / unhandled error** → if `.solo/states/` exists, output `<solo:redo/>` to go back to build with fix; otherwise fix and redeploy
- **No errors in 30 lines of logs** → proceed to report

**If logs show zero traffic (fresh deploy), make a few test requests:**
```bash
curl -s https://{deployment-url}/           # homepage
curl -s https://{deployment-url}/api/health  # API health (if exists)
```
Then re-check logs for any errors triggered by these requests.

### Step 7. Post-Deploy Report

```
Deployment: {project-name}

  Platform:  {platform}
  URL:       {deployment-url}
  Branch:    main
  Commit:    {sha}

  Done:
    - [x] Code pushed to GitHub
    - [x] Deployed to {platform}
    - [x] Database migrations applied (or N/A)

  Manual steps remaining:
    - [ ] Set environment variables (listed above)
    - [ ] Custom domain (optional)
    - [ ] PostHog / analytics setup (optional)

  Next: /review — final quality gate
```

## Completion

### Signal completion

If `.solo/states/` directory exists, output this exact tag ONCE and ONLY ONCE — the pipeline detects the first occurrence:
```
<solo:done/>
```
**Do NOT repeat the signal tag anywhere else in the response.** One occurrence only.
If `.solo/states/` directory does not exist, skip the signal tag.

## Error Handling

### CLI not found
**Cause:** Platform CLI not installed.
**Fix:** Install the specific CLI: `npm i -g vercel`, `npm i -g wrangler`, `brew install flyctl`, `brew install supabase/tap/supabase`.

### Deploy fails — build error
**Cause:** Build works locally but fails on platform (different Node version, missing env vars).
**Fix:** Check platform build logs. Ensure `engines` in package.json matches platform. Set missing env vars.

### Database connection fails
**Cause:** DATABASE_URL not set or network rules block connection.
**Fix:** Check connection string, platform's DB dashboard, IP allowlist.

### Git push rejected
**Cause:** Remote has diverged.
**Fix:** `git pull --rebase origin main`, resolve conflicts, push again.

## Verification Gate

Before reporting "deployment successful":
1. **Run** `curl -s -o /dev/null -w "%{http_code}"` against the deployment URL.
2. **Verify** HTTP 200 (not 404, 500, or redirect loop).
3. **Check** the actual page content matches expectations (not a blank page or error).
4. **Only then** report the deployment as successful.

Never say "deployment should be live" — verify it IS live.

## Critical Rules

1. **Use installed CLIs** — detect `vercel`, `wrangler`, `supabase`, `fly`, `sst` before falling back to `npx`.
2. **Auto-deploy aware** — if platform auto-deploys on push, just push. Don't run manual deploy commands unnecessarily.
3. **NEVER commit secrets** — no .env files with real values, no API keys in code.
4. **Preview before production** — deploy preview first, verify, then promote to prod.
5. **Check build locally first** — `pnpm build` / `uv build` (or equivalent) before deploying.
6. **Check production logs** — always tail logs after deploy, catch runtime errors before declaring success.
7. **Report all URLs** — deployment URL + platform dashboard links.
8. **Infrastructure in repo** — prefer `sst.config.ts` or `fly.toml` over manual dashboard config.
9. **Verify before claiming done** — HTTP 200 from the live URL + clean logs, not just "deploy command succeeded".
