What it does
Rnd Tech Arch Diagrammer is an agent skill from chendongqi/OPB-Skills. Technical architecture diagram creator using Excalidraw MCP tools. Use when users need to (1) Create system architecture diagrams, (2) Draw flowcharts, sequence diagrams, or topology diagrams, (3) Visualize technical concepts (data flows, deployment architectures), (4) Generate documentation diagrams for code or infrastructure. Trigger keywords: 画图、架构图、流程图、时序图、diagram, flowchart, architecture, sequence diagram, data flow, topology, visualization.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/diagram-best-practices.md` and `references/excalidraw-file-format.md`).
It sits in Development, covering Diagrams. It works with Excalidraw. The repository describes itself as: 一套覆盖一个公司完整业务的SKILL，适用ClaudeCode，Codex，OpenCode等工具.

What it can do on your machine
Read from SKILL.md and the folder at commit d587882. 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
Rnd Tech Arch Diagrammer loads about 1.7k tokens when it runs, and up to ~6.8k if it reads all its reference files. Until then it costs about 119 tokens; SKILL.md has 687 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 687 words (~1,735 tokens).
“Create clear, professional technical diagrams using Excalidraw MCP tools. Translate technical concepts into visual representations including architecture diagrams, flowcharts, sequence diagrams, and more.”
