Operating System Visualization is an agent skill from mingchen666/Reviva. Use this skill whenever the user wants visual learning for operating systems, process states, CPU scheduling, Gantt charts, synchronization, semaphore/PV problems, deadlock, Banker's algorithm, memory management, paging, address translation, page replacement, file systems, disk scheduling, or 408 OS review.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including assets (for example `config.json`).
It sits in Product & Project Management, covering Project management and Translation. The repository describes itself as: Local-first AI learning workspace — ask, note, review and create around your own materials. Wiki KB, Agents, Skills, creation tools.Private NotebookLM Alternative.AI….
Read from SKILL.md and the folder at commit 24bde40. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
file_readfile_writeFrom allowed-tools in the SKILL.md frontmatter.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Operating System Visualization loads about 1.2k tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 487 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.
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.
Without a licence we can't republish the file, so here is its outline and opening line. It has 487 words (~1,164 tokens).
“Create visual explanations for operating system mechanisms. The goal is to make queues, states, resources, and address mappings observable.”

Run `npx skills add mingchen666/Reviva --skill operating-system-visualization -a claude-code`. Or copy the skill folder (electron/builtin-assets/skills/operating-system-visualization in mingchen666/Reviva) into .claude/skills/operating-system-visualization in your project. Claude Code loads it when a task matches its description.
Run `npx skills add mingchen666/Reviva --skill operating-system-visualization -a codex`. Or copy the skill folder (electron/builtin-assets/skills/operating-system-visualization in mingchen666/Reviva) into .agents/skills/operating-system-visualization in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add mingchen666/Reviva --skill operating-system-visualization -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/operating-system-visualization, .gemini/skills/operating-system-visualization, .github/skills/operating-system-visualization and .opencode/skills/operating-system-visualization in your project.
SKILL.md names no scripts, command-line tools or credentials: Operating System Visualization is instructions for the agent only. Its frontmatter pre-approves these tools: file_read, file_write.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
No licence was found for Operating System Visualization or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
About 1.2k tokens (SKILL.md is roughly 4.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
