What it does
Microsim Generator is an agent skill from dmccreary/ibook-skills. Creates interactive educational MicroSims, routing to the best-matched generator - p5.js, Chart.js, Plotly, Mermaid, vis-network, timelines, maps, Venn, causal-loop/feedback-loop diagrams (CLD), concept-classifier sorting quizzes, infographic overlays with callout labels, Docker Python labs (runnable code blocks), and fact-verified statistics posters (every numeric claim checked against a cited source before rendering). Generates complete MicroSim packages with HTML, JavaScript, CSS, documentation, and metadata.
Its SKILL.md is about 11k tokens, which your agent loads only when the skill is triggered. The skill folder holds 133 other files, including scripts, reference files and assets (for example `assets/causal-loop/cld-inline.js`, `assets/causal-loop/cld-viewer/cld-viewer.js` and `assets/causal-loop/cld-viewer/examples/ai-flywheel-cld.json`).
It sits in Data & Analytics, covering Diagrams, Data visualization and Infographics. It works with Python, Docker, JavaScript and Chart.js.

What it can do on your machine
Read from SKILL.md and the folder at commit 6789126. 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 1 file in scripts/ (JavaScript, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
python3pipplaywright
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:
dmccreary.github.io
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Microsim Generator loads about 11k tokens when it runs, and up to ~121k if it reads all its reference files. Until then it costs about 134 tokens; SKILL.md has 4,403 words of instructions outside code blocks.
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 4,403 words (~11,196 tokens).

What does Microsim Generator need to run?
Going by SKILL.md and its folder, Microsim Generator needs JavaScript for the scripts in its folder and the command-line tools its instructions call (python3, pip and playwright). Our summary lists: Python 3; Node.js; Docker.
Does Microsim Generator access the network?
SKILL.md names 1 domain. In commands or code: dmccreary.github.io; the agent is likely to contact it when it follows the instructions. This is read from the text; nothing was executed.
Is Microsim Generator safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Microsim Generator use?
No licence was found for Microsim Generator or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Microsim Generator use?
About 11k tokens (SKILL.md is roughly 45k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 110k tokens, read only when the agent opens those files.
