SectorForge ships in two forms, for two different Claude surfaces.
For Claude Code (CLI) and the Cowork / Code view in Claude Desktop. Install via marketplace — see the top-level README:
/plugin marketplace add dakesec/SectorForge
/plugin install sector-forge@sectorforge
For regular Claude Desktop / Claude.ai chat threads, which can't load Claude Code plugins but can load uploaded Agent Skills that run in the code-execution sandbox.
skill/sector-forge/— the skill source (SKILL.md + scripts + references + example). This is the same engine, with paths made relative to the skill folder and a Pillow-install step for the sandbox.sector-forge.skill— the packaged, uploadable file (a zip with a.skillextension;sector-forge/at its root).
- Open Settings → Capabilities → Skills (custom-skill upload requires a plan that supports it, e.g. Pro/Max/Team/Enterprise).
- Choose Upload skill and select
sector-forge.skill. - Start a new chat and ask for a map ("make me a sci-fi battlemap of …"). The
skill runs
scripts/build_map.pyin the sandbox and returns the.dd2vtt/ Foundry JSON / PNG for download.
# from the repo root, refresh the skill copy of the engine, then:
python dist/build_skill.py # (or re-zip dist/skill/sector-forge into dist/sector-forge.skill)
