Linq — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the linq-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 linq --cli-only
   

2. Verify: linq-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/social-and-messaging/linq/cmd/linq-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.

Community-curated OpenAPI 3.1 blueprint for the Linq Partner API, derived from https://docs.linqapp.com/api and cross-checked against github.com/linq-team/linq-go/api.md. The blueprint is generic and contains no private deployment-specific behavior or examples.

Generic Linq messaging experience

Use these commands for ordinary Linq rich messaging.

Core workflow:

linq-pp-cli compose preview --text "Congrats!" --effect screen:confetti --decorate 0:8:bold --preferred-service iMessage --agent
linq-pp-cli compose send --chat-id ch_123 --text "Congrats!" --effect screen:confetti --idempotency-key req_123 --agent --dry-run

Typing indicators:

linq-pp-cli typing start --chat-id ch_123 --agent --dry-run
linq-pp-cli typing stop --chat-id ch_123 --agent --dry-run
linq-pp-cli typing pulse --chat-id ch_123 --dwell 800ms --agent --dry-run
tail -f ./debug/linq-webhooks.ndjson | linq-pp-cli typing watch --agent
linq-pp-cli webhooks add-event sub_123 chat.typing_indicator.started chat.typing_indicator.stopped --agent --dry-run
linq-pp-cli webhooks doctor --subscription-id sub_123 --agent
linq-pp-cli capability check +15551234567 --agent

Effects and decorations:

linq-pp-cli effects list --agent
linq-pp-cli effects preview --text "Hello world" --decorate 0:5:bold --decorate 6:11:shake --agent

Attachments:

linq-pp-cli attachments plan --file ./photo.jpg --agent
linq-pp-cli attachments upload --file ./photo.jpg --agent --dry-run
linq-pp-cli attachments send-url --chat-id ch_123 --url https://cdn.example/photo.jpg --text "Photo attached" --agent --dry-run
linq-pp-cli attachments send-id --chat-id ch_123 --attachment-id att_123 --text "Photo attached" --agent --dry-run
linq-pp-cli attachments audit-url https://cdn.example/photo.jpg --agent
linq-pp-cli attachments cleanup --attachment-id att_123 --agent --dry-run

Rich link previews:

linq-pp-cli link-preview audit https://example.com --agent
linq-pp-cli link-preview send --chat-id ch_123 --url https://example.com --agent --dry-run
linq-pp-cli link-preview metadata https://example.com --agent --dry-run

Reactions and contact sharing:

linq-pp-cli react add --message-id msg_123 --type like --agent --dry-run
linq-pp-cli react remove --message-id msg_123 --type like --agent --dry-run
linq-pp-cli react custom --message-id msg_123 --emoji "tada" --agent --dry-run
linq-pp-cli contact-share preflight --chat-id ch_123 --from +16282893046 --agent --dry-run
linq-pp-cli contact-share send --chat-id ch_123 --from +16282893046 --yes --agent --dry-run

Protocol rules to preserve: typing, effects, and decorations are iMessage-only; inbound typing indicators are push-only webhook events and this CLI only manages subscriptions or inspects captured streams; rich previews and reactions work on iMessage/RCS and simplify on SMS; link preview parts must be the only part; first outbound chat openers must not contain links.

For inbound typing awareness, enable both typing events on the target subscription with a dry-run first:

linq-pp-cli webhooks add-event sub_123 chat.typing_indicator.started chat.typing_indicator.stopped --agent --dry-run
linq-pp-cli webhooks doctor --subscription-id sub_123 --agent

webhook-subscriptions update-awebhook-subscription sends a full replacement subscribed_events array for that field, not a delta. Prefer webhooks add-event / remove-event so the CLI fetches the current set, validates event names against webhook-events, computes the union/diff, and sends the correct replacement array.

Finding the right command

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

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

linq-pp-cli auth set-token YOUR_TOKEN_HERE

Or set LINQ_API_V3_API_KEY as an environment variable.

Run linq-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:

  linq-pp-cli contact-card get --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:

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

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

linq-pp-cli profile save briefing --json
linq-pp-cli --profile briefing contact-card get
linq-pp-cli profile list --json
linq-pp-cli profile show briefing
linq-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 linq-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

1. Install the MCP server:

   go install github.com/mvanhorn/printing-press-library/library/social-and-messaging/linq/cmd/linq-pp-mcp@latest
   

2. Register with Claude Code:

   claude mcp add linq-pp-mcp -- linq-pp-mcp
   

3. Verify: claude mcp list

Direct Use

1. Check if installed: which linq-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:

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

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