Skills are slash commands that extend Claude Code with pre-built workflows for maritime data queries.

​
Installation

If you ran datadocked-mcp --setup, skills are already installed.
The DataDocked MCP Server must be installed and configured with your API key.

​
Basic Skills

Quick lookups using single API calls.

/track-vessel

1 credit · IMO, MMSI, or nameReal-time position, speed, course, and ETA for any vessel. Vessel names are resolved using search_vessel_by_name.
/track-vessel Ever Given
/track-vessel 9811000

/vessel-info

5 credits · IMO, MMSI, or nameComprehensive vessel details including type, flag, dimensions, tonnage, engine specs, and management info. Vessel names are resolved using search_vessel_by_name.
/vessel-info MSC Oscar
/vessel-info 9247431

/port-traffic

5 credits · Port codeView arrivals and departures at any port worldwide.
/port-traffic SGSIN
/port-traffic NLRTM

​
Intelligence Reports

Comprehensive reports combining multiple data sources.

/vessel-dossier

~13 credits · IMO, MMSI, or nameComplete intelligence report combining position, specifications, management, port history, and PSC inspections. Vessel names are resolved using search_vessel_by_name.
/vessel-dossier 9811000
/vessel-dossier Ever Given
  • Current position & navigation status
  • Full vessel specifications (from get_vessel_details)
  • Engine & fuel details
  • Owner, operator & manager info
  • Recent port calls
  • PSC inspection history (requires IMO)
  • Risk assessment score

/voyage-brief

~38 credits · IMO, MMSI, or nameCurrent voyage narrative with weather conditions, route context, and ETA analysis. Vessel names are resolved using search_vessel_by_name.
/voyage-brief Ever Given
/voyage-brief 9811000
  • Current voyage details
  • Weather at vessel location
  • Historical position data
  • Port call context
  • ETA reliability analysis

​
Fleet & Area Monitoring

Track multiple vessels or monitor geographic regions.

/fleet-monitor

~3 credits/vessel · IMO or MMSITrack multiple vessels in a dashboard view with real-time positions. Uses bulk endpoint then fetches details by IMO.
/fleet-monitor 9811000, 9321483, 9454450
  • Position for each vessel
  • Speed & heading comparison
  • ETA summary table
  • Fleet status overview

/area-watch

~85 credits · Circular searchMonitor all vessels in a geographic region using circular search (center point + radius, max 50km).
/area-watch 1.25, 103.75, 50 tanker
/area-watch Singapore Strait tanker
  • All vessels within radius
  • Filter by vessel type
  • Position & heading data
  • Traffic density analysis
Maximum radius is 50 km. Uses circular search with latitude, longitude, and radius_km.

​
Compliance & Risk

Assess vessel compliance and operational risk.

/compliance-audit

~10 credits · IMO onlyPSC risk assessment with detention history and deficiency analysis.
/compliance-audit 9811000
  • PSC inspection history
  • Detention records
  • Deficiency breakdown
  • Risk score calculation
  • Flag state performance
PSC inspections require IMO number. Resolve vessel names to IMO first using /track-vessel.

/port-intel

~55 credits · Port codeComprehensive port activity analysis with traffic patterns.
/port-intel SGSIN
/port-intel NLRTM
  • Recent arrivals/departures
  • Vessel type breakdown
  • Traffic volume trends
  • Average port time
  • Key operators analysis

​
Historical Analysis

Analyze vessel patterns over time.

/route-history

~156 credits (30 days) · IMO or MMSIHistorical voyage patterns and port call analysis over time.
/route-history 9811000 90
  • Historical positions
  • Port call timeline
  • Trade route patterns
  • Seasonal variations
  • Speed/efficiency trends

/competitor-watch

~210 credits · Circular searchAnalyze vessels by owner/operator in a specific region using circular search (max 50km).
/competitor-watch 25.0, -90.0, 50
/competitor-watch Singapore Strait
  • Vessels by operator
  • Fleet composition
  • Market share analysis
  • Activity patterns
Maximum radius is 50 km. Uses circular search with latitude, longitude, and radius_km.

​
Usage Tips

Vessel Name Resolution

Skills accept vessel names (e.g., “Ever Given”). Names are resolved to IMO/MMSI using search_vessel_by_name (+1 credit).

Use IMO Numbers

IMO numbers (7 digits) are most reliable and skip the name lookup. PSC inspections require IMO only.

Check Credits First

Each skill shows estimated cost before execution.

Combine Skills

Start with /track-vessel to get IMO, then use /vessel-dossier for deep dives.
