Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

wargame-map scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/wargame-map - Generate Wargame-Style Maps

Generate historically accurate, playable wargame-style hex maps for any geographic area at any scale. Produces static PNG/PDF, interactive HTML, and game data JSON.

Usage

/wargame-map <area or scenario description> [options]
/wargame-map --spec <yaml_file>

Examples

  • /wargame-map Normandy 1944 --hex-size 5
  • /wargame-map Eastern Front 1941 --hex-size 50 --style simonsen
  • /wargame-map Stalingrad tactical --hex-size 1 --style kibler
  • /wargame-map Persian Gulf --hex-size 25
  • /wargame-map --spec configs/examples/normandy_hex.yaml

Prerequisites

This skill requires the wargame-cartographer Python package. On first use, clone and install:

git clone https://github.com/fredzannarbor/wargame-cartographer.git ~/wargame-cartographer
cd ~/wargame-cartographer
uv sync

Implementation

When invoked, follow these steps:

1. Locate Installation

Find the wargame-cartographer installation:

# Check common locations
ls ~/wargame-cartographer/pyproject.toml 2>/dev/null || \
ls ./pyproject.toml 2>/dev/null

If not found, tell the user to install it first.

2. Ensure Dependencies

cd ~/wargame-cartographer
uv sync

3. Parse Input

If --spec is provided, use that YAML file directly:

cd ~/wargame-cartographer
uv run wargame-map generate <spec_file>

If natural language, construct a MapSpec YAML:

  1. Geocode the area: Use the description to determine a bounding box. For well-known scenarios:

    • "Normandy 1944" → bbox: -1.80,48.80,0.50,49.80
    • "Eastern Front" → bbox: 20.0,45.0,42.0,60.0
    • "Stalingrad" → bbox: 43.8,48.4,44.8,49.0
    • "North Africa" → bbox: -5.0,28.0,25.0,38.0
    • "Pacific Theater" → bbox: 90.0,-10.0,180.0,50.0
    • "Gettysburg" → bbox: -77.30,39.78,-77.20,39.86
    • "Bulge" → bbox: 5.5,49.5,6.8,50.5
    • For other areas, use OSM Nominatim or estimate from geography knowledge
  2. Infer scale from keywords:

    • "tactical" or hex-size < 5 → 1-5 km hexes
    • "operational" or default → 5-25 km hexes
    • "strategic" or hex-size > 25 → 25-100 km hexes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
