What is adventure-plot?

A step that turns a high-level creative prompt into a structured adventure plan stored in adventure.md. The plan describes the module's story and guides later building steps.

Use it to outline a Neverwinter Nights adventure from its theme, level range, and tone, including the plot that later steps will follow.

It gives the other adventure-building steps a shared written source instead of requiring each one to invent its own details.

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.

Model	Per session	Once invoked
Fable 5	$0.00042	$0.01958
Opus 5	$0.00021	$0.00979
Sonnet 5	$0.00008	$0.00392
Haiku 4.5	$0.00004	$0.00196

Security

Grade A, and why

adventure-plot 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plot

Sub-skill of /create-adventure. Takes a creative prompt (theme, level range, tone) and generates a complete structured adventure document at adventure.md. All downstream skills read from this file.

Prerequisites

The module should already be loaded (created by the /create-adventure orchestrator during pre-flight).
adventure.md already exists in the MCP temp directory with the # Adventure: [Title] heading and ## Module section. This skill appends the ## Plot section to it.

File Location

adventure.md is in the MCP temp directory: $MCP_FOLDER_TEMP (defaults to $TEMP/nwn-mcp or /tmp/nwn-mcp). Read the existing file first, then rewrite it with the full content (preserving the existing heading and module section).

Workflow

Fully autonomous. Generate all narrative content from the user's creative prompt — do NOT ask the user for input.

Pre-Check: Validate adventure.md

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

## Module

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: Understand Context

Read the existing adventure.md to get the title, module metadata, and target level.
Call get_module_summary to understand the loaded module state.
Call list_areas to see what locations already exist.
Call list_tilesets to understand what spatial environments are available. This informs what kinds of locations are buildable (forest, dungeon, crypt, city, interior, castle, etc.). Do NOT design locations that require tilesets or terrain types that don't exist.

Phase 2: Generate the Adventure

Rewrite adventure.md preserving the existing # Adventure: [Title] heading and ## Module section, then appending the full ## Plot section using the structure below. Every section is required — downstream skills depend on specific headings and field names.

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.
