diagram-design

diagram-design is a skill for Claude Code, Codex from baokhang83/fluencyloop. It costs 61 tokens per session (2,046 once invoked), scanned A, original, Apache-2.0.

A guide for creating technical and product diagrams as self-contained HTML files using inline SVG, a format for drawing scalable graphics.

In plain words
What is it for?
Use it to create architecture, flow, sequence, state, data, and process diagrams, including specified FluencyLoop documentation diagrams.
Why use it?
It helps choose a diagram type that clearly shows relationships, flows, structures, or states while keeping the result portable and free of external dependencies.

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.

Security

Grade A, and why

diagram-design 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 — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Diagram Design

Create one self-contained HTML file with inline SVG and CSS. Use a diagram only when it explains a relationship, flow, or structure better than prose or a table.

FluencyLoop embedded diagram fast path

Use this path when FluencyLoop asks for either docs/fluencyloop/diagrams/product-overview.html or a file under docs/fluencyloop/diagrams/records/. For a product overview, its prose is always docs/fluencyloop/distillations/product.md; its companion is always docs/fluencyloop/diagrams/product-overview.html. Never write docs/fluencyloop/product.md. It is a focused companion inside FluencyLoop's local site, not a branded design-system deliverable.

FluencyLoop owns the surrounding site design, but the diagram must still describe the product faithfully. Use a self-contained HTML document with inline SVG and CSS: no scripts, remote URLs, remote fonts, iframes, or embedded executable content. Support the reader's themes with local light tokens and a :root[data-fluencyloop-theme="dark"] token override.

Choose the rendering path by topology, not by the convenience of the renderer:

  1. Use the native renderer only when one of its layouts faithfully captures every material node and relationship: linear for a 2–6 step path, hub for a shared service/boundary with 2–7 direct participants, merge for inputs or short chains that end at one result, or layered for one-to-one adjacent-layer mappings. It supports 2–8 nodes and at most 10 edges. A graph with parallel flows that merge and then continue to another boundary does not fit these layouts; never recast the architecture merely to make the command pass.

  2. For a fitting native graph, run exactly one fluencyloop diagram command. Give each node its short id, label, and detail as separate fields, then give the directed edges. For example:

    fluencyloop diagram --output docs/fluencyloop/diagrams/product-overview.html --layout hub \
  --title "Dog selection" --hub selection \
  --node list --label "Dog list" --detail "Chooses a dog" \
  --node selection --label "Selection service" --detail "Owns selected dog" \
  --node detail --label "Dog detail" --detail "Reads selected dog" \
  --edge list selection --edge selection detail

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.
