nwn-mcp: Skill for Claude Code

Areas

Sub-skill of /create-adventure. Reads the plot section of adventure.md, builds all areas required by the plot, and appends an areas summary back to adventure.md.

Prerequisites

• adventure.md must exist in the MCP temp directory ($MCP_FOLDER_TEMP, defaults to $TEMP/nwn-mcp or /tmp/nwn-mcp) and contain a completed ## Plot section. All sub-skills read from and append to this shared file.
• A module must be loaded. If none is loaded, call load_module using the module name from adventure.md.

Workflow

Fully autonomous. Make all decisions based on the plot document — do NOT ask the user for input.

Phase 0: Clean Up Starter Area

If the module was created by create_module, it contains a temporary _start area (MicroSet 3x3). Before building real areas:

1. Call remove_object to remove _start from the GIT if needed
2. The first real area you create will become the new entry area — after creating it, update the IFO entry point: use modify_gff_field to set Mod_Entry_Area to the new area's resref, and set Mod_Entry_X/Mod_Entry_Y to a walkable position in that area
3. Remove _start from Mod_Area_list in the IFO, and delete _start.are, _start.git, _start.gic from the temp dir

Pre-Check: Validate adventure.md

Read adventure.md from the MCP temp directory. Verify these sections exist and are non-empty:

• ## Module
• ## Plot

If any required section is missing or contains no content below its heading: STOP. Output: "ERROR: adventure.md is missing required section [name]. The prerequisite skill has not run or failed. Cannot proceed."

Phase 1: Read the Plot

Read adventure.md. Extract from the ## Plot section:

• Locations — all areas that need to be built (name, type, description)
• Setting — interior or exterior? What biome/environment per location?
• Mood — dark, peaceful, eerie, bustling, etc.
• Scale — how large should each area be?
• Connections — which areas connect to which (for door/transition planning)
