+name: deploy-company-linux
+description: Deploy, publish, update, inspect, or roll back Docker Compose and Dockerfile applications on the company internal Linux server at 192.168.31.51. Use when Codex is asked to deploy a local project to the company server, release a new version, check a deployed application, establish deployment SSH access, or restore the previous release.
+---
+
+# Deploy Company Linux
+
+Deploy applications to the company Linux host through SSH with release directories, health checks, and automatic rollback.
+
+## Workflow
+
+1. Read `references/server-profile.md` before choosing ports or a deployment name.
+2. Inspect the project, including `AGENTS.md`, Git status, Docker files, environment examples, volumes, ports, and health endpoints.
+3. Prefer an existing `compose.yaml`, `compose.yml`, `docker-compose.yaml`, or `docker-compose.yml`. Use Dockerfile mode only when no Compose configuration exists.
+4. Derive a lowercase app name that starts with a letter or digit and contains only letters, digits, underscores, and hyphens. Do not reuse an existing application name unless the user is updating that application.
+5. Detect port collisions against the server profile and a live preflight. Ask only when the intended application name, public port, or health endpoint cannot be inferred safely.
+6. Authenticate with an SSH key. If key authentication is unavailable, use `COMPANY_LINUX_PASSWORD` only for the current process. Never write a password into the skill, repository, deployment archive, command output, or shell history.
+7. Run preflight before deployment:
+
+   ```powershell
+   powershell -ExecutionPolicy Bypass -File scripts/deploy.ps1 `
+     -Action preflight -AppName <app-name>
+   ```
+
+8. Deploy from the project root:
+
+   ```powershell
+   powershell -ExecutionPolicy Bypass -File scripts/deploy.ps1 `
+     -Action deploy -ProjectPath <absolute-project-path> `
+     -AppName <app-name> -Mode auto `
+     -HealthUrl <remote-health-url>
+   ```
+
+9. Report the release path, containers, exposed endpoint, and health result. If the command fails, report whether automatic rollback succeeded and include the smallest relevant log excerpt.
+
+## Authentication Setup
+
+Prefer an existing SSH key. For first-time setup, set the password only in the current PowerShell process, run the setup script, then remove it:
+
+```powershell
+$env:COMPANY_LINUX_PASSWORD = Read-Host "Company Linux password"
+powershell -ExecutionPolicy Bypass -File scripts/setup-ssh-key.ps1
+Remove-Item Env:COMPANY_LINUX_PASSWORD
+```
+
+The setup script adds the current user's Ed25519 public key to `/home/jsxq/.ssh/authorized_keys`. Treat this as a server change and run it only when the user authorizes SSH key setup.
+
+## Dockerfile Mode
+
+When deploying a Dockerfile without Compose, provide both ports if the application must be reachable:
+
+```powershell
+powershell -ExecutionPolicy Bypass -File scripts/deploy.ps1 `
+  -Action deploy -ProjectPath <path> -AppName <name> `
+  -Mode dockerfile -PublishPort 8800 -ContainerPort 8000 `
+  -HealthUrl http://127.0.0.1:8800/health
+```
+
+Use `.env` as the container environment file when it exists. Do not print its contents.
+
+## Status and Rollback
+
+Check status:
+
+```powershell
+powershell -ExecutionPolicy Bypass -File scripts/deploy.ps1 `
+  -Action status -AppName <app-name>
+```
+
+Roll back to the previous successful release:
+
+```powershell
+powershell -ExecutionPolicy Bypass -File scripts/deploy.ps1 `
+  -Action rollback -AppName <app-name>
+```
+
+## Safety Rules
+
+- Deploy only under `/home/jsxq/apps/<app-name>`.
+- Keep application data in named Docker volumes or explicit shared directories. Warn before deploying Compose files that bind persistent data to source-relative paths.
+- Never run `docker system prune`, remove Docker volumes, delete unrelated containers, modify firewall rules, or use `sudo` as part of the normal workflow.
+- Do not deploy an unreviewed `.env` accidentally. Verify that it belongs to the target environment without revealing its values.
+- Do not expose database, Redis, administrative, or debug ports unless the user explicitly requires it.
+- Treat a production-named application or an existing public port as high impact; show the detected target before updating it.
+- Preserve the previous release. The remote script automatically restores it when a supplied health check fails.
+
+## Bundled Scripts
+
+- `scripts/deploy.ps1`: preflight, deploy, status, and rollback entry point for Windows/Codex Desktop.
+- `scripts/remote-deploy.sh`: deterministic release and rollback logic executed on the server.
+- `scripts/setup-ssh-key.ps1`: optional one-time SSH key bootstrap.
+- `scripts/ssh-askpass.cmd`: reads the temporary password environment variable without storing a password in the file.
