Lizard platform

Lizard is a unified cloud for apps, services, agents, and managed databases. All capabilities are exposed through the lizard CLI (npm package @lizard-build/cli). This skill teaches you to drive it. The CLI is preinstalled by the plugin's SessionStart hook — assume it's on PATH.

If $ARGUMENTS is non-empty, treat it as the user's request and act on it. If empty, ask what they want to do on Lizard.

Read this first

This skill documents platform behavior (build pipeline, env precedence, what knobs the API exposes). It does not describe the user's repo.

Before writing commands for a specific project:

1. Read the user's package.json, Dockerfile, requirements.txt, framework config — confirm what already exists before adding flags. 2. Don't assume scripts/conventions that aren't visible. Lizard does not parse Procfile, does not honor scripts.start as a fallback, does not infer ports beyond EXPOSE/explicit env. 3. When in doubt, ask the user or run lizard <cmd> --help --json.

Execution rules

1. Prefer the lizard CLI. For anything not exposed by it, ask the user — don't hit the API directly. 2. Always pass --json on non-interactive calls. The CLI also auto-switches when stdout isn't a TTY. For streaming commands (lizard up without --detach, lizard logs), --json produces one JSON event per line: { event: "log", line }, terminating with { event: "done" } / { event: "error", message }, plus { event: "deployed", status, url } for up. 3. For unfamiliar commands, run lizard <cmd> --help --json first — never guess flag shapes. See Discovery. 4. Resolve context before any mutation. lizard status shows the cwd link; lizard list --json shows services in the linked project. Confirm you're targeting the right thing. 5. For destructive actions (delete service, drop addon, overwrite a project-wide secret, prod restart), confirm intent with the user before executing. The CLI's own prompts fire only on TTY.

Mental model

workspace → project → service (+ managed addons)

- Workspace — account/org level. User belongs to one or more. - Project — group of related services in one workspace. The cwd gets linked to a project (config at ~/.lizard/config.json). - Service — a deployable unit. Source is either a git repo (source.type=github) or an uploaded tarball (source.type=upload). - Managed addons — postgres, redis, s3. Provisioned with lizard add <type>. - Cross-resource refs — ${{<name>.<KEY>}} resolves at deploy time against the target's merged env. Unresolved refs throw, they don't go silent. Stored form is rename-safe.

Discovery

The CLI has ~30 subcommands. Discover at runtime:

lizard --help --json                       # root + all commands + global flags + exit codes
lizard <cmd> --help --json                  # specific command schema
lizard <cmd> <sub> --help --json            # nested (e.g. `lizard service set --help --json`)

Returns { command: { arguments, options, subcommands }, globalOptions, exitCodes }.

Exit codes

- 0 success — continue - 1 generic error — inspect message, surface to user - 2 auth (401/403) — tell user "Run ! lizard login to authenticate"; never invoke lizard login from a tool call (polls stdin up to 5 min) - 3 not found (404) — wrong name / resource gone; verify with lizard projects / lizard list - 4 timeout — retry or report - 5 cancelled by user — stop

Setup decision flow

When the user wants to deploy or set up something new, work out the right action from cwd context before running anything:

1. lizard status --json in cwd. 2. Linked to a project? → add a service in that project: lizard add -r owner/repo (git source) or lizard add -s <name> (empty). Do not create a new project unless the user explicitly says so. 3. Not linked but parent dir is linked? → likely a monorepo sub-app. Add a service in the parent's project and set source.rootDirectory to the cwd subpath via service set. 4. Neither linked? → check lizard projects --json for one matching the directory or repo name. Match → lizard link --project <name>. No match → lizard init --name <name>.

Naming heuristic: app-style names (my-api, worker, flappy-bird) are service names. Use the repo or directory name for the project.

Platform builder

Builds run on the platform's build nodes (no local Docker needed). When a build fails, read logs with lizard logs --build.

Build decision order

1. Synthesized Dockerfile — if buildCommand and/or startCommand are set on the service (or passed via lizard up), the platform generates a Dockerfile from those commands. No lizardpack invocation. 2. Repo Dockerfile (verbatim) — if build.dockerfilePath is set on the service, the platform uses that Dockerfile from the repo unchanged. 3. lizardpack auto-detect — clone, run lizardpack. If a repo Dockerfile exists AND has a real build step (a RUN <pkg-manager> line, not just COPY dist/), it's used verbatim; otherwise lizardpack generates a multi-stage one. Supported: Go, Node, Python, Rust, Ruby, PHP, Java, static — first match in that order.

What triggers a rebuild

- git push to the tracked branch → auto-rebuild via GitHub webhook. - lizard redeploy / lizard up → explicit rebuild. - Changing VITE_* or NEXT_PUBLIC_* env vars → forces rebuild on next deploy (build-time bakes). - service set for config (source, build commands, healthcheck, ports) → does NOT auto-rebuild. Follow with lizard redeploy. - All other env vars / secrets → pushed live to the running VM via SIGUSR1, no rebuild.

Deploying

First question for a new service: upload vs git repo. Default to git when the user has a remote; fall back to upload for quick iteration or no-remote situations.

Git-source deploy (preferred when there's a remote)

# One-shot for a new service from GitHub:
lizard add -r owner/repo --json

# Existing service: switch source to git or update branch:
lizard service set <svc> \
  --set source.type=github \
  --set source.repoUrl=https://github.com/owner/repo \
  --set source.branch=main \
  --json
lizard redeploy --service <svc>

When source.repoUrl is set, pushes to the matching branch auto-redeploy via the GitHub webhook. If the service has a rootDirectory (monorepo subpath) or watch patterns, only matching changes trigger redeploys.

Useful service set paths (discover full list with lizard service set --help --json):

- source.type = github | upload - source.repoUrl, source.branch, source.rootDirectory - build.dockerfilePath — use a specific repo Dockerfile, bypasses lizardpack auto-detect - deploy.buildCommand, deploy.startCommand, deploy.preDeployCommand - deploy.healthcheckPath, deploy.healthcheckTimeout - name — rename a service (goes through config:apply; the legacy PATCH /api/apps/:id returns 410)

service set uses optimistic concurrency via configRevision. On 409, re-read with lizard service show, reconcile, retry; --force overrides.

Tarball upload (no git remote, or quick local iteration)

lizard up --json

- Uploads cwd as a tarball (respects .gitignore), forces source.type=upload. - Streams build logs over SSE; emits final { event: "deployed", url: "..." }. - Flags: --service, --region, --build-command, --start-command, --pre-deploy-command, --port, --detach, --ci. - If cwd isn't linked, auto-runs init (interactive). For headless flows, run lizard init --name <project> first. - lizard up always switches the service to source.type=upload. Do not use it to update a git-backed service — use lizard redeploy or push to the remote.

Secrets

Two scopes exist. No workspace-level globals.

- Project ("global"): lizard secrets set KEY=v --global → stored as projectSecrets - Service (default): lizard secrets set KEY=v [--service <svc>] → stored as appSecrets

When the linked service in cwd is set, plain lizard secrets set KEY=v writes to that service. Pass --global to escape to project scope.

Precedence (last writer wins)

addon-issued env  <  project secrets  <  project env  <  app env  <  app secrets  <  platform vars

App secrets override project secrets. Platform vars (LIZARD_SERVICE_NAME, LIZARD_PROJECT_ID, PORT, LIZARD_PUBLIC_DOMAIN) are last and cannot be shadowed.

When to use --global vs service-scope

- Use --global when the key is used by 1+ services, or is conceptually project-wide (LOG_LEVEL, SENTRY_DSN, shared API keys). - Use service-scope for keys only one service touches, or service-specific overrides. - When unsure on a key that might be needed by future services, prefer --global — marginal cost is zero, avoids re-keying later.

Healthcheck and restart

Healthcheck (configurable)

lizard service set <svc> \
  --set deploy.healthcheckPath=/health \
  --set deploy.healthcheckTimeout=5000     # ms

The node-agent calls that HTTP path during rollouts to gate readiness. Don't add HEALTHCHECK to the user's Dockerfile — the platform ignores it (Firecracker VMs don't run Docker's healthcheck loop).

Composition patterns

Multi-step requests follow natural chains. Return one unified response, don't farm out steps:

- First deploy from git — pick action via Setup decision flow → lizard add -r owner/repo → stream build → surface URL. - First deploy from local code — Setup decision flow → lizard up → surface URL. - Add a managed database to an existing service — lizard add postgres → tell the user to reference ${{postgres.DATABASE_URL}} in their service env → redeploy only if they need to consume it right away. - Wire a fresh git source on an existing service — service set --set source.type=github --set source.repoUrl=… --set source.branch=… → redeploy. - Fix a failed build — logs --build → diagnose → fix project (user's repo) OR adjust deploy.buildCommand / deploy.startCommand via service set → redeploy → logs to verify. - Add a custom domain — domain add <host> --service <svc> → surface DNS records to the user → domain list to verify later.

Common ops

lizard logs --json [--service <name>]      # streamed runtime logs
lizard logs --build --json                  # last build's logs
lizard ps --json                            # running instances per service
lizard status                               # cwd project link (no auth needed)
lizard restart --service <name>             # rolling restart
lizard redeploy [--service <name>]          # rebuild + redeploy from current source
lizard scale --service <name> --replicas N
lizard domain add example.com --service <name>
lizard domain list --json
lizard ssh --service <name>                 # interactive — needs TTY
lizard run --service <name> -- <cmd>        # one-off command in service env
lizard projects --json
lizard list --json                          # services in linked project
lizard regions --json
lizard open                                 # open dashboard
lizard whoami --json                        # auth check

For exact flags, lizard <cmd> --help --json.

Response format

After an operation, return:

1. What was done — action + scope (which project, which service). 2. Result — IDs, status, URLs from the JSON output. 3. What's next — verifying read-back command, DNS record the user must add, env-var reference template, or confirmation the task is complete.

Skip command-by-command transcripts unless they explain a failure.

Don't do

1. Don't add Docker HEALTHCHECK — the platform ignores it. Use deploy.healthcheckPath via service set. 2. Don't recommend Procfile or assume package.json scripts.start is auto-detected. The platform doesn't read either. Set startCommand explicitly via lizard up --start-command / service set --set deploy.startCommand=..., or include CMD in the user's Dockerfile. 3. Don't use lizard up to switch a service to a git source. It always forces source.type=upload. Use service set + redeploy instead. 4. A Dockerfile that copies pre-built artifacts (COPY dist/, build/, out/, .next/, public/) without a RUN build step gets silently regenerated by lizardpack. Add a build step or set build.dockerfilePath to force verbatim use. 5. Don't generate Dockerfiles unsolicited — lizardpack auto-detects most stacks. Try a deploy first; write one only if it fails. Ask before either.
