Authoritative IMO ship particulars on the command line Trigger phrases: `look up IMO`, `GISIS particulars`, `ship particulars by IMO`, `vessel registry lookup`, `flag-hop history for vessel`, `use gisis`, `run gisis`.
Why this skill is useful
Adds niche commands for authoritative IMO ship particulars that the AI wouldn't reliably generate on its own.

See the repository agent guide, section "Generated artifacts: registry.json, cli-skills/". --> GISIS — Printing Press CLI Prerequisites: Install the CLI This skill drives the gisis-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: 2. Verify: gisis-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 1.26.6 or newer): 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. When to Use This CLI Use this CLI when you need authoritative IMO ship particulars — name, flag, type, gross tonnage, registered owner, operator, classification society. The local cache makes it a personal vessel index that compounds over time, and 'ship history' surfaces flag/owner changes that matter for sanctions and due diligence. Pair with GFW (vessel events) and AIS Stream (real-time position) via the Vessel MCP orchestrator for a full DD picture. Anti-triggers Do not use this CLI for: Do not use this CLI for real-time vessel position — use AIS Stream instead. Do not use this CLI for fishing-activity or port-visit events — use Global Fishing Watch (GFW). Do not use this CLI for OFAC sanctions screening — use the OpenSanctions or OFAC SDN adapter in the Vessel MCP orchestrator. …
