At a glance

Creates interactive causal-loop diagram (CLD) articles for MkDocs Material sites.

  • Works in 5 steps: One JSON file per loop… → One full-system JSON combining all loops… → The article markdown (docs/articles/.md)… → …
  • The user wants to visualize feedback loops
  • SKILL.md covers What the user gets, When to use this skill, High-level workflow and Bundled assets, plus 5 more sections
  • Runs JavaScript scripts from its folder

What it does

Causal Loop Diagram Generator is an agent skill from dmccreary/ibook-skills. Creates interactive causal-loop diagram (CLD) articles for MkDocs Material sites. Use when the user wants to visualize feedback loops, systems archetypes (reinforcing/balancing loops, limits to growth, tragedy of the commons), or any topic with competing runaway and stabilizing dynamics. Produces vis-network diagrams — not static images or Mermaid.

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 18 other files, including reference files and assets (for example `assets/cld-inline.js`, `assets/cld-viewer/cld-viewer.js` and `assets/cld-viewer/examples/ai-flywheel-cld.json`).

It sits in Development, covering Diagrams. It works with Mermaid.

When your agent uses it

  • The user wants to visualize feedback loops
  • Systems archetypes (reinforcing/balancing loops
  • Limits to growth
  • Tragedy of the commons)

Example prompts

  • “Use the causal-loop-diagram-generator skill to create interactive causal-loop diagram (CLD) articles for MkDocs Material sites”
  • “/causal-loop-diagram-generator”

Requirements

  • Node.js

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. One JSON file per loop (docs/sims/cld-viewer/examples/-cld.json) — usually 3–5 nodes each, one per archetype loop in the topic.
  2. One full-system JSON combining all loops around a shared central node.
  3. The article markdown (docs/articles/.md) — progressive build-up, one section per loop, with inline interactive diagrams and a…
  4. The shared infrastructure (docs/articles/cld-inline.js, docs/sims/cld-viewer/) if not already present in the project.
  5. Updated mkdocs.yml nav entries.

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 script files (JavaScript), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    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

Causal Loop Diagram Generator loads about 2.1k tokens when it runs, and up to ~8.6k if it reads all its reference files. Until then it costs about 95 tokens; SKILL.md has 916 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~95
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.6k

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); files beside SKILL.md are not scanned.

SKILL.md

Its licence (CC-BY-NC-4.0) doesn't allow us to republish the file, so here is its outline and opening line. It has 916 words (~2,128 tokens).

“This skill produces a complete, working multi-CLD article for an MkDocs Material site. The output is a set of files that together render an article where each section discusses one feedback loop and shows it as an interactive draggable diagram…”
