Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00064 | $0.00722 |
| Opus 5 | $0.00032 | $0.00361 |
| Sonnet 5 | $0.00013 | $0.00144 |
| Haiku 4.5 | $0.00006 | $0.00072 |
Grade A, and why
create-material 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 2d 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.

Create Material
Overview
Use this skill to turn a rough story-material prompt into a complete materials/*.md source file.
Always follow AGENTS.md and materials/_template.md. Generate useful seed material from the prompt, ask for missing information and intended story use, revise from feedback, then write only after confirmation.
Before running a bundled command, resolve <skill-dir> to the absolute directory
containing this SKILL.md. This keeps the same skill usable from either the
repository-local skill tree or the Novelist plugin.
Workflow
1. Read Context
Read:
AGENTS.mdproject.mdmaterials/_template.md- Existing files in
materials/ - Relevant
characters/,macguffins/,plot/,outlines/, andworld/files if referenced
2. Generate A Material Draft
From the user's prompt, infer a compact first-pass material note in Korean. Include:
- material category, such as
scene-seed,motif,object,line,research,theme,image,conflict, orclue - raw idea
- possible story use
- related characters, MacGuffins, plot threads, or settings
- whether it is canonical yet
- constraints, risks, or questions
- open decisions the user should make
Mark inferred items clearly. Keep uncertain ideas as status: seed and canonical: false.
3. Ask For Direction
Ask the user what role this material should play:
- background texture or major plot driver
- literal object or metaphor
- one-scene use or recurring motif
- clue, red herring, image system, dialogue seed, or research note
- canonical fact or scratch seed
Continue the feedback loop until the user says it is enough or gives enough detail to save.
4. Build The Material File
Use a filesystem-safe ASCII slug. Save to materials/<slug>.md; id must be material-<slug>.
Required frontmatter:
id: material-ascii-slug
type: material
title: ""
category: scene-seed
status: seed
source: ""
canonical: false
related_characters: []
related_macguffins: []
plot_threads: []
used_in_chapters: []
created: YYYY-MM-DD
updated: YYYY-MM-DD
tags: []
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

create-material is a skill published in the GitHub repository comfuture/novelist (5 stars, last pushed 1mo ago), licensed MIT. It adds 64 tokens to every session and 722 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
