name: marine-watch-planner description: Generate and adapt a sea-duty daily routine with watch rotations, sleep protection, duty handovers, internet-budgeted work blocks, and role-specific tasks. Use when a user asks to build or optimize an onboard schedule by vessel type, role, timezone, watch model (e.g., 4/4, 3/3), fatigue constraints, or low-bandwidth life at sea.

Marine Watch Planner

Overview

Build a practical 24h onboard routine that protects sleep, keeps safety anchors, and fits real constraints (role duties, sea state, and limited internet).

Workflow

1. Capture context inputs. 2. Select watch/sleep model. 3. Generate 24h timeline. 4. Add safety anchors and handovers. 5. Add bandwidth-aware work/content policy. 6. Return concise schedule + non-negotiables.

1) Capture context inputs

Collect only required inputs:

vessel type: cargo / tanker / offshore / yacht / fishing / ferry

role: captain / OOW / engineer / deck crew / passenger

timezone (IANA)

watch model: 4/4, 3/3, 6/6, solo cycle

start of first watch (local time)

internet limit (GB/week)

priorities: sleep, productivity, fitness, content, study

If data is missing, assume: 2-person 4/4, start 08:00, timezone Europe/Vilnius, 4 GB/week.

2) Select watch/sleep model

Use references/watch-models.md. Rules:

Protect minimum 6h sleep/day, target 7h.

Keep one uninterrupted core block >=3h when possible.

No cognitively heavy tasks immediately after fragmented sleep.

3) Generate 24h timeline

Use scripts/build_marine_plan.py for a starter plan. Required blocks:

on-watch blocks

sleep/rest blocks

meal/hydration

weather/navigation review

role duty block

optional online work + posting window

4) Add safety anchors

Use references/safety-anchors.md. Always include:

start-of-watch handover checklist

2-4 safety scans/day

end-of-day log line

5) Add internet policy

Use references/internet-budgeting.md. Always provide:

daily MB target from weekly limit

one low-traffic day/week

"offline-first" recommendations (downloads, no autoplay, no cloud sync on cellular)

6) Output format

Return exactly these sections:

1. Status: one line. 2. 24h Plan: bullet list HH:MM–HH:MM — action. 3. Non-negotiables: max 5 bullets. 4. Traffic budget: one line daily MB target + one line policy.

Keep it short, operational, and in the user language.
