What it does

Visual Docs Diagrams is an agent skill from hashgraph-online/awesome-codex-plugins. Design and review visual content for developer documentation, including screenshots, architecture diagrams, boxes-and-arrows diagrams, flowcharts, swimlanes, video decisions, accessibility, performance, annotations, and visual maintenance. Use when creating or auditing diagrams, screenshots, visual explanations, or media in technical docs.

Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `guidelines.md`, `references/core/knowledge.md` and `workflows/design-technical-visual.md`). Compatibility notes: Codex, Claude Code, and other Agent Skills-compatible clients.

It sits in Development, covering Diagrams. The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is MIT.

When your agent uses it

  • Auditing diagrams
  • Visual explanations
  • Media in technical docs

Example prompts

  • “/visual-docs-diagrams”

Requirements

  • Compatibility (from SKILL.md): Codex, Claude Code, and other Agent Skills-compatible clients.

Workflow steps

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

  1. Load guidelines.md to choose the smallest useful reference set.
  2. Define what the visual must help the reader understand or do.
  3. Choose screenshot, diagram, flowchart, swimlane, or text-only based on the task.
  4. Use workflows/design-technical-visual.md for full visual design or review.
  5. Check accessibility, performance, placement, source files, and maintenance before finalizing.

What it can do on your machine

Read from SKILL.md and the folder at commit 78497e5. 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

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    Links to these hosts (documentation or services it may open):

    • link.springer.com

    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.

  • Compatibility

    Codex, Claude Code, and other Agent Skills-compatible clients.

    From compatibility in the SKILL.md frontmatter.

Context cost

Visual Docs Diagrams loads about 683 tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 91 tokens; SKILL.md has 255 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~91
When it runs · the whole SKILL.md, loaded when a task matches
~683
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.8k

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.

Visual Docs Diagrams

Use this skill to decide whether developer docs need visuals and to design or review those visuals for comprehension, accessibility, performance, and maintainability.

This skill is derived from Docs for Developers: An Engineer's Field Guide to Technical Writing, especially Chapter 6, "Adding visual content." The guidance is transformed and paraphrased; do not copy book prose into user outputs. Source: https://link.springer.com/book/10.1007/978-1-4842-7217-6

Quick Start

  1. Load guidelines.md to choose the smallest useful reference set.
  2. Define what the visual must help the reader understand or do.
  3. Choose screenshot, diagram, flowchart, swimlane, or text-only based on the task.
  4. Use workflows/design-technical-visual.md for full visual design or review.
  5. Check accessibility, performance, placement, source files, and maintenance before finalizing.

Default Output

When designing or reviewing visual docs, return:

  1. Visual purpose - what the reader must understand faster or better.
  2. Recommended visual type - screenshot, boxes-and-arrows, flowchart, swimlane, video, or no visual.
  3. Design notes - scope, labels, annotations, contrast, placement, and format.
  4. Accessibility and performance checks - alt text, captions, transcripts, SVG/image size, responsiveness.
  5. Maintenance plan - source file, owner, update trigger, and review cadence.

Core Posture

  • Use visuals to supplement text, not replace critical instructions.
  • Prefer one idea or level of detail per visual.
  • Treat accessibility and maintenance as part of visual design, not post-production polish.
  • Avoid video unless the motion itself is necessary and maintenance is realistic.
