xAI — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the xai-pp-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 xai --cli-only
   

2. Verify: xai-pp-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 1.26.5 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/ai/xai/cmd/xai-pp-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.

Use xAI's REST API from scripts and agents with JSON-first output, local cache support, and MCP tooling. The CLI keeps the official bearer-token contract and exposes read-only inspection commands for model and credential health checks.

Unique Capabilities

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

Model planning

• model-picker — Rank live xAI models for a task using the authenticated model catalog.

  Use this before generation, vision, embedding, image, or video workflows when an agent needs a valid model ID.

  xai-pp-cli model-picker --task reasoning --json --select recommendations.model,recommendations.why
  

• model-capabilities — Build a live capability matrix for the authenticated xAI model catalog.

  Use this when an agent needs to choose between chat, reasoning, vision, embedding, image, and video surfaces.

  xai-pp-cli model-capabilities --json --select models.id,models.capabilities
  

Cost and readiness

• cost-preview — Estimate xAI token cost from live model pricing metadata before sending a request.

  Use this before a large request to estimate prompt and completion cost from xAI's current model metadata.

  xai-pp-cli cost-preview --task chat --input-tokens 2000 --output-tokens 500 --json
  

• smoke-chat — Verify that the authenticated key can run a tiny xAI chat completion.

  Use this after auth setup to prove inference works, not only that the key is syntactically valid.

  xai-pp-cli smoke-chat --yes --json --select model,success,content_preview
  

• api-key — Inspect the authenticated xAI API key status and permissions without exposing the secret value.

  Use this when a workflow fails with authorization errors and the agent needs a safe credential-health check.

  xai-pp-cli api-key --json --select api_key_blocked,api_key_disabled,acls
  

Agent readiness

• api — Browse the complete generated xAI endpoint surface by interface for agent planning and fallback calls.

  Use this when a task needs an endpoint that is not obvious from the top-level command list.

  xai-pp-cli api

Finding the right command

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

xai-pp-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.

Auth Setup

Run xai-pp-cli auth setup for the URL and steps to obtain a token (add --launch to open the URL). Then store it:

xai-pp-cli auth set-token YOUR_TOKEN_HERE

Or set XAI_API_KEY as an environment variable.

Run xai-pp-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:

  xai-pp-cli api-key --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:

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

Entries are stored locally at ~/.local/share/xai-pp-cli/feedback.jsonl. They are never POSTed unless XAI_FEEDBACK_ENDPOINT is set AND either --send is passed or XAI_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.

xai-pp-cli profile save briefing --json
xai-pp-cli --profile briefing api-key
xai-pp-cli profile list --json
xai-pp-cli profile show briefing
xai-pp-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 xai-pp-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

Install the MCP binary from this CLI's published public-library entry or pre-built release, then register it:

claude mcp add xai-pp-mcp -- xai-pp-mcp

Verify: claude mcp list

Direct Use

1. Check if installed: which xai-pp-cli If not found, offer to install (see Prerequisites at the top of this skill).
2. Match the user query to the best command from the Unique Capabilities and Command Reference above.
3. Execute with the --agent flag:

   xai-pp-cli <command> [subcommand] [args] --agent
   

4. If ambiguous, drill into subcommand help: xai-pp-cli <command> --help.
