What it does

Story Generator is an agent skill from dmccreary/ibook-skills. Generates illustrated graphic novel narratives about scientists, mathematicians, and historical figures for intelligent textbooks, with image prompts for each panel. Use when adding historical-figure or case-study stories to a textbook's Stories section.

Its SKILL.md is about 10k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `references/index-template.md`, `scripts/fix-references.py` and `scripts/generate-images.py`).

It sits in Media & Creative, covering Comics and storyboards.

When your agent uses it

Example prompts

Requirements

Python 3
A Bash shell

Workflow steps

4 steps, taken from the step headings in SKILL.md.

What it can do on your machine

Read from SKILL.md and the folder at commit 98a9991. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 4 files in scripts/ (Python and Shell), which the agent can run.
Shell commands in SKILL.md call:
- python3
- pip
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- en.wikipedia.org
- dmccreary.github.io
- mathshistory.st-andrews.ac.uk
- britannica.com
Also links to:
- aistudio.google.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- GEMINI_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Story Generator loads about 10k tokens when it runs, and up to ~12k if it reads all its reference files. Until then it costs about 68 tokens; SKILL.md has 5,075 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~68
When it runs · the whole SKILL.md, loaded when a task matches: ~10k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~12k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 5,075 words (~10,428 tokens).

“This skill generates complete graphic novel narratives about key contributors to science, mathematics, and technology — and fictional case-study stories — for intelligent textbooks built with MkDocs Material. The default story length is 12 panels plus a cover (13 images…”
