What it does
Diagram Design is an agent skill from byungjunjang/slide-master. Diagram design reference library (14 types — architecture, flowchart, sequence, state, ER, timeline, swimlane, quadrant, nested, tree, org chart, layers, venn, pyramid). In ppt-master this is consumed by the Executor when hand-authoring diagram-type SVG pages — it is NOT a standalone HTML generator here. Read for deep per-type layout conventions.
Its SKILL.md is about 340 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Diagrams and HTML artifacts. It works with Python. The repository describes itself as: AI 에이전트가 PowerPoint에서 진짜 편집되는 네이티브 PPTX를 만드는 워크플로우. The licence is MIT.
When your agent uses it
- Tasks that involve Diagrams
- Tasks that involve HTML artifacts
Example prompts
- “/diagram-design”
Requirements
- Python 3
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Read .claude/skills/diagram-design/SKILL.md (repo-root relative) in full and execute it
- Resolve paths: treat ${SKILL_DIR} as .claude/skills/diagram-design. Bare relative paths
- Run all commands from the repository root. On Windows installs without
What it can do on your machine
Read from SKILL.md and the folder at commit f2d9fef. 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
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
Diagram Design loads about 335 tokens when it runs. Until then it costs about 91 tokens; SKILL.md has 109 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); files beside SKILL.md are not scanned.

diagram-design (Codex discovery stub)
This file is generated by sync_codex_stubs.py so Codex discovers the skill.
The authoritative skill lives in this repository at .claude/skills/diagram-design/ — a single
source of truth shared by Claude Code and Codex. Do not hand-edit this stub;
edit the canonical tree, then re-run:
python3 .claude/skills/ppt-master/scripts/sync_codex_stubs.pyOn invocation:
- Read
.claude/skills/diagram-design/SKILL.md(repo-root relative) in full and execute it exactly as a runtime procedure. - Resolve paths: treat
${SKILL_DIR}as.claude/skills/diagram-design. Bare relative paths mentioned inside the skill (references/...,workflows/...,scripts/...,templates/...) resolve against that directory — never against.codex/skills/. - Run all commands from the repository root. On Windows installs without
python3.exe, rerun the same command withpython.
