--- name: deploy-to-vercel description: Deploy applications and websites to Vercel. Use when the user requests deployment actions like "deploy my app", "deploy and give me the link", "push this live", or "create a preview deployment". metadata: author: vercel version: "3.0.0" --- # Deploy to Vercel Deploy any project to Vercel. **Always deploy as preview** (not production) unless the user explicitly asks for production. The goal is to get the user into the best long-term setup: their project linked to Vercel with git-push deploys. Every method below tries to move the user closer to that state. ## Step 1: Gather Project State Run all four checks before deciding which method to use: ```bash # 1. Check for a git remote git remote get-url origin 2>/dev/null # 2. Check if locally linked to a Vercel project (either file means linked) cat .vercel/project.json 2>/dev/null || cat .vercel/repo.json 2>/dev/null # 3. Check if the Vercel CLI is installed and authenticated vercel whoami 2>/dev/null # 4. List available teams (if authenticated) vercel teams list --format json 2>/dev/null ``` ### Team selection If the user belongs to multiple teams, present all available team slugs as a bulleted list and ask which one to deploy to. Once the user picks a team, proceed immediately to the next step — do not ask for additional confirmation. Pass the team slug via `--scope` on all subsequent CLI commands (`vercel deploy`, `vercel link`, `vercel inspect`, etc.): ```bash vercel deploy [path] -y --no-wait --scope ``` If the project is already linked (`.vercel/project.json` or `.vercel/repo.json` exists), the `orgId` in those files determines the team — no need to ask again. If there is only one team (or just a personal account), skip the prompt and use it directly. **About the `.vercel/` directory:** A linked project has either: - `.vercel/project.json` — created by `vercel link` (single project linking). Contains `projectId` and `orgId`. - `.vercel/repo.json` — created by `vercel link --repo` (repo-based linking). Contains `orgId`, `remoteName`, and a `projects` array mapping directories to Vercel project IDs. Either file means the project is linked. Check for both. **Do NOT** use `vercel project inspect`, `vercel ls`, or `vercel link` to detect state in an unlinked directory — without a `.vercel/` config, they will interactively prompt (or with `--yes`, silently link as a side-effect). Only `vercel whoami` is safe to run anywhere. ## Step 2: Choose a Deploy Method ### Linked (`.vercel/` exists) + has git remote → Git Push This is the ideal state. The project is linked and has git integration. 1. **Ask the user before pushing.** Never push without explicit approval: ``` This project is connected to Vercel via git. I can commit and push to trigger a deployment. Want me to proceed? ``` 2. **Commit and push:** ```bash git add . git commit -m "deploy: " git push ``` Vercel automatically builds from the push. Non-production branches get preview deployments; the production branch (usually `main`) gets a production deployment. 3. **Retrieve the preview URL.** If the CLI is authenticated: ```bash sleep 5 vercel ls --format json ``` The JSON output has a `deployments` array. Find the latest entry — its `url` field is the preview URL. If the CLI is not authenticated, tell the user to check the Vercel dashboard or the commit status checks on their git provider for the preview URL. --- ### Linked (`.vercel/` exists) + no git remote → `vercel deploy` The project is linked but there's no git repo. Deploy directly with the CLI. ```bash vercel deploy [path] -y --no-wait ``` Use `--no-wait` so the CLI returns immediately with the deployment URL instead of blocking until the build finishes (builds can take a while). Then check on the deployment status with: ```bash vercel inspect ``` For production deploys (only if user explicitly asks): ```bash vercel deploy [path] --prod -y --no-wait ``` --- ### Not linked + CLI is authenticated → Link first, then deploy The CLI is working but the project isn't linked yet. This is the opportunity to get the user into the best state. 1. **Ask the user which team to deploy to.** Present the team slugs from Step 1 as a bulleted list. If there's only one team (or just a personal account), skip this step. 2. **Once a team is selected, proceed directly to linking.** Tell the user what will happen but do not ask for separate confirmation: ``` Linking this project to on Vercel. This will create a Vercel project to deploy to and enable automatic deployments on future git pushes. ``` 3. **If a git remote exists**, use repo-based linking with the selected team scope: ```bash vercel link --repo --scope ``` This reads the git remote URL and matches it to existing Vercel projects that deploy from that repo. It creates `.vercel/repo.json`. This is much more reliable than `vercel link` (without `--repo`), which tries to match by directory name and often fails when the local folder and Vercel project are named differently. **If there is no git remote**, fall back to standard linking: ```bash vercel link --scope ``` This prompts the user to select or create a project. It creates `.vercel/project.json`. 4. **Then deploy using the best available method:** - If a git remote exists → commit and push (see git push method above) - If no git remote → `vercel deploy [path] -y --no-wait --scope `, then `vercel inspect ` to check status --- ### Not linked + CLI not authenticated → Install, auth, link, deploy The Vercel CLI isn't set up at all. 1. **Install the CLI (if not already installed):** ```bash npm install -g vercel ``` 2. **Authenticate:** ```bash vercel login ``` The user completes auth in their browser. If running in a non-interactive environment where login is not possible, skip to the **no-auth fallback** below. 3. **Ask which team to deploy to** — present team slugs from `vercel teams list --format json` as a bulleted list. If only one team / personal account, skip. Once selected, proceed immediately. 4. **Link the project** with the selected team scope (use `--repo` if a git remote exists, plain `vercel link` otherwise): ```bash vercel link --repo --scope # if git remote exists vercel link --scope # if no git remote ``` 5. **Deploy** using the best available method (git push if remote exists, otherwise `vercel deploy -y --no-wait --scope `, then `vercel inspect ` to check status). --- ### No-Auth Fallback — claude.ai sandbox **When to use:** Last resort when the CLI can't be installed or authenticated in the claude.ai sandbox. This requires no authentication — it returns a **Preview URL** (live site) and a **Claim URL** (transfer to your Vercel account). ```bash bash /mnt/skills/user/deploy-to-vercel/resources/deploy.sh [path] ``` **Arguments:** - `path` - Directory to deploy, or a `.tgz` file (defaults to current directory) **Examples:** ```bash # Deploy current directory bash /mnt/skills/user/deploy-to-vercel/resources/deploy.sh # Deploy specific project bash /mnt/skills/user/deploy-to-vercel/resources/deploy.sh /path/to/project # Deploy existing tarball bash /mnt/skills/user/deploy-to-vercel/resources/deploy.sh /path/to/project.tgz ``` The script auto-detects the framework from `package.json`, packages the project (excluding `node_modules`, `.git`, `.env`), uploads it, and waits for the build to complete. **Tell the user:** "Your deployment is ready at [previewUrl]. Claim it at [claimUrl] to manage your deployment." --- ### No-Auth Fallback — Codex sandbox **When to use:** In the Codex sandbox where the CLI may not be authenticated. Codex runs in a sandboxed environment by default — try the CLI first, and fall back to the deploy script if auth fails. 1. **Check whether the Vercel CLI is installed** (no escalation needed for this check): ```bash command -v vercel ``` 2. **If `vercel` is installed**, try deploying with the CLI: ```bash vercel deploy [path] -y --no-wait ``` 3. **If `vercel` is not installed, or the CLI fails with "No existing credentials found"**, use the fallback script: ```bash skill_dir="" # Deploy current directory bash "$skill_dir/resources/deploy-codex.sh" # Deploy specific project bash "$skill_dir/resources/deploy-codex.sh" /path/to/project # Deploy existing tarball bash "$skill_dir/resources/deploy-codex.sh" /path/to/project.tgz ``` The script handles framework detection, packaging, and deployment. It waits for the build to complete and returns JSON with `previewUrl` and `claimUrl`. **Tell the user:** "Your deployment is ready at [previewUrl]. Claim it at [claimUrl] to manage your deployment." **Escalated network access:** Only escalate the actual deploy command if sandboxing blocks the network call (`sandbox_permissions=require_escalated`). Do **not** escalate the `command -v vercel` check. --- ## Agent-Specific Notes ### Claude Code / terminal-based agents You have full shell access. Do NOT use the `/mnt/skills/` path. Follow the decision flow above using the CLI directly. For the no-auth fallback, run the deploy script from the skill's installed location: ```bash bash ~/.claude/skills/deploy-to-vercel/resources/deploy.sh [path] ``` The path may vary depending on where the user installed the skill. ### Sandboxed environments (claude.ai) You likely cannot run `vercel login` or `git push`. Go directly to the **no-auth fallback — claude.ai sandbox**. ### Codex Codex runs in a sandbox. Check if the CLI is available first, then fall back to the deploy script. Go to the **no-auth fallback — Codex sandbox**. --- ## Output Always show the user the deployment URL. - **Git push:** Use `vercel ls --format json` to find the preview URL. If the CLI isn't authenticated, tell the user to check the Vercel dashboard or commit status checks. - **CLI deploy:** Show the URL returned by `vercel deploy --no-wait`. Use `vercel inspect ` to check build status and report it to the user. - **No-auth fallback:** Show both the preview URL and the claim URL: ``` Deployment successful! Preview URL: https://my-app-abc123.vercel.app Claim URL: https://vercel.com/claim-deployment?code=... View your site at the Preview URL. To transfer this deployment to your Vercel account, visit the Claim URL. ``` **Do not** curl or fetch the deployed URL to verify it works. Just return the link. --- ## Troubleshooting ### Network Egress Error (claude.ai) If deployment fails due to network restrictions on claude.ai, tell the user: ``` Deployment failed due to network restrictions. To fix this: 1. Go to https://claude.ai/settings/capabilities 2. Add *.vercel.com to the allowed domains 3. Try deploying again ``` ### Escalated Network Access (Codex / sandboxed environments) If deployment fails due to network issues (timeouts, DNS errors, connection resets) in a sandboxed environment, rerun with escalated permissions (`sandbox_permissions=require_escalated`). Do not escalate the initial CLI availability check — only escalate the actual deploy command. Example guidance to the user: ``` The deploy needs escalated network access to deploy to Vercel. I can rerun the command with escalated permissions — want me to proceed? ``` ### CLI Auth Failure If `vercel login` or `vercel deploy` fails with authentication errors, fall back to the no-auth deploy script (claude.ai or Codex variant, depending on the environment).
