Level - Printing Press CLI

Prerequisites: Install the CLI

This skill drives the levelio-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:

   npx -y @mvanhorn/printing-press-library install levelio --cli-only
   

2. Verify: levelio-cli --version
3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.4 or newer). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead:

go install github.com/mvanhorn/printing-press-library/library/monitoring/levelio/cmd/levelio-cli@latest

If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.

levelio-cli syncs your entire Level estate - devices, groups, tags, custom fields, alerts, and OS updates - into a local SQLite database, then answers portfolio-wide questions offline that the Level web UI shows one device at a time. Match every API operation with agent-native output (--json/--select/--csv), then transcend with weighted at-risk ranking, fleet-wide patch posture, per-client posture scorecards, group-clustered alert triage, reboot-debt tracking, and custom-field coverage audits.

When to Use This CLI

Use levelio-cli when an agent or technician needs a portfolio-wide answer about a Level-managed fleet - at-risk endpoints, patch exposure, alert clusters, stale agents, security-score distribution, or custom-field gaps - rather than a single device's detail. It is the right tool for cross-entity rollups, anti-joins (what is missing), and scriptable RMM automation, all offline against a synced local store.

Anti-triggers

Do not use this CLI for:

• single-device detail lookups (use devices show , not the fleet analytics commands)
• real-time monitoring without a prior sync - analytics commands read the local store
• authoring automations, scripts, or monitoring policies - the public API only triggers automation webhooks

Unique Capabilities

These capabilities aren't available in any other tool for this API.

Cross-entity fleet intelligence

• at-risk - Rank the worst endpoints across every axis at once - active alerts, pending patches, low security score, and how long they have been dark - as a single weighted risk score.

  Reach for this when an agent needs the single prioritized 'fix these first' list across the whole fleet instead of one health axis at a time.

  levelio-cli at-risk --top 20 --agent
  

• patch-posture - Aggregate OS updates across the fleet - available vs installed, by category and device, including patches that errored - so you can see exposure at a glance.

  Use when an agent must report fleet-wide patch exposure or pick which category of updates to push next.

  levelio-cli patch-posture --category security --agent
  

• fleet - One-screen inventory rollup, cross-tabbed any way you slice it - by OS, platform, group, or tag - with online and maintenance counts.

  Reach for this for a portfolio-wide inventory answer instead of paging through device lists.

  levelio-cli fleet --by os --online --agent
  

• alert-triage - Cluster unresolved alerts by group and severity with device context, so systemic fires surface above one-off noise.

  Reach for this to answer 'where are my fires and which are systemic' in one call.

  levelio-cli alert-triage --severity critical --group-by group --agent
  

• client-scorecard - One row per top-level group (client) with device count, online %, open critical alerts, average security score, stale count, and patch exposure - the QBR-ready per-client rollup.

  Reach for this when an agent needs per-client fleet posture in one table - which client is worst, where to focus - instead of walking groups and devices one call at a time.

  levelio-cli client-scorecard --agent
  

Health and drift

• stale - List devices that have gone dark - not seen in N days - with an option to exclude machines intentionally in maintenance mode.

  Use to find agents that silently stopped checking in without chasing each device in the UI.

  levelio-cli stale --days 14 --exclude-maintenance --agent
  

• group-tree - Render the Level group hierarchy with each node showing its real rolled-up health - descendant device, alert, stale, and score counts.

  Use to see the org structure annotated with where the problems actually concentrate.

  levelio-cli group-tree --with alerts,stale,score --agent
  

• since - Show what changed in a recent time window - new alerts, newly published updates, and devices last seen - so you can answer 'what happened since I last looked'.

  Reach for this at the start of a shift to catch up on everything that moved overnight.

  levelio-cli since --hours 24 --agent
  

• alert-recurrence - Rank which alert names fire most often across the fleet and on how many distinct devices, so chronically noisy monitors surface above one-off fires.

  Reach for this when the question is which monitors are chronically noisy and worth tuning, not which fires are burning right now (use alert-triage for that).

  levelio-cli alert-recurrence --top 15 --agent
  

• reboot-due - List devices waiting on a reboot to finalize installed patches - and how long they have been waiting - joined with online and maintenance state.

  Reach for this when patches are installed but not yet effective - the reboot backlog is the gap between patch posture on paper and in reality.

  levelio-cli reboot-due --days 3 --agent
  

Governance and hygiene

• cf-coverage - Audit which devices, groups, or the org are missing a custom-field value - the absence the UI can't show - via an anti-join.

  Reach for this when an agent must enforce data hygiene - e.g. every device must carry an asset-tag or warranty field.

  levelio-cli cf-coverage --missing --agent
  

• security-posture - Show the fleet security-score distribution and everyone under a threshold, optionally rolled up by group.

  Use to report fleet security posture or target the weakest endpoints for remediation.

  levelio-cli security-posture --below 70 --by-group --agent
  

• tag-audit - Surface tag-data drift: devices with zero tags, orphan tags applied to nothing, and duplicate tag names that fragment the fleet.

  Reach for this when fleet filters and automations misbehave because tag data drifted - untagged devices and orphan tags are invisible until audited.

  levelio-cli tag-audit --agent

Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

levelio-cli which "<capability in your own words>"

which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match - fall back to --help or use a narrower query.

Recipes

Morning fleet catch-up

levelio-cli since --hours 12 --agent

Everything that changed overnight - new alerts, new updates, devices that checked in - in one structured payload.

Patch-day exposure report

levelio-cli patch-posture --category security --agent --select summary,by_category

Fleet-wide pending vs installed security updates, narrowed to just the rollup fields an agent needs.

Find the worst endpoints fast

Devices that have not checked in for a week and are not in maintenance - the silent-failure list.

Data-hygiene audit

levelio-cli cf-coverage --missing --agent

Every assignee missing a custom-field value, so required asset/warranty data can be backfilled.

Per-client QBR rollup

levelio-cli client-scorecard --agent

One row per client group - devices, online %, open criticals, average security score, stale count, and patch exposure - ready for a QBR slide.

Auth Setup

Authenticate with a Level API key (Settings -> API keys; read-only is enough for every list/show/sync/analytics command). Export it as LEVEL_API_TOKEN; it is sent as 'Authorization: Bearer '.

Run levelio-cli doctor to verify setup.

Agent Mode

Add --agent to any command. Expands to: --json --compact --no-input --no-color --yes.

• Pipeable - JSON on stdout, errors on stderr

• Filterable - --select keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:

  levelio-cli alerts list --agent --select id,name,status
  

• Previewable - --dry-run shows the request without sending

• Offline-friendly - sync/search commands can use the local SQLite store when available

• Non-interactive - never prompts, every input is a flag

• Explicit retries - use --idempotent only when an already-existing create should count as success, and --ignore-missing only when a missing delete target should count as success

Response envelope

Commands that read from the local store or the API wrap output in a provenance envelope:

{
  "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
  "results": <data>
}

Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal AND no machine-format flag (--json, --csv, --compact, --quiet, --plain, --select) is set - piped/agent consumers and explicit-format runs get pure JSON on stdout.

Agent Feedback

When you (or the agent) notice something off about this CLI, record it:

levelio-cli feedback "the --since flag is inclusive but docs say exclusive"
levelio-cli feedback --stdin < notes.txt
levelio-cli feedback list --json --limit 10

Entries are stored locally at ~/.local/share/levelio-cli/feedback.jsonl. They are never POSTed unless LEVELIO_FEEDBACK_ENDPOINT is set AND either --send is passed or LEVELIO_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.

Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.

Output Delivery

Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:

Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.

Named Profiles

A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.

levelio-cli profile save briefing --json
levelio-cli --profile briefing alerts list
levelio-cli profile list --json
levelio-cli profile show briefing
levelio-cli profile delete briefing --yes

Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.

Exit Codes

Argument Parsing

Parse $ARGUMENTS:

1. Empty, help, or --help → show levelio-cli --help output
2. Starts with install → ends with mcp → MCP installation; otherwise → see Prerequisites above
3. Anything else → Direct Use (execute as CLI command with --agent)

MCP Server Installation

1. Install the MCP server:
