바이트코드 컴파일러 + 스택 VM 설계 가이드. An agent skill from revfactory/claude-code-harness.

- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Bytecode Vm Design is an agent skill from revfactory/claude-code-harness. 바이트코드 컴파일러 + 스택 VM 설계 가이드. MiniLang을 바이트코드로 컴파일하고 VM에서 실행할 때 사용한다.
Its SKILL.md is about 460 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/closure-upvalue.md` and `references/opcode-reference.md`).
Example prompts
- “/bytecode-vm-design”
What it can do on your machine
Read from SKILL.md and the folder at commit 267005c. 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 (its code samples are javascript).
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
Bytecode Vm Design loads about 463 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 21 tokens; SKILL.md has 20 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 20 words (~463 tokens).

How do I install Bytecode Vm Design in Claude Code?
Run `npx skills add revfactory/claude-code-harness --skill bytecode-vm-design -a claude-code`. Or copy the skill folder (experiments/results/case-013/harness/.claude/skills/bytecode-vm-design in revfactory/claude-code-harness) into .claude/skills/bytecode-vm-design in your project. Claude Code loads it when a task matches its description.
How do I install Bytecode Vm Design in Codex?
Run `npx skills add revfactory/claude-code-harness --skill bytecode-vm-design -a codex`. Or copy the skill folder (experiments/results/case-013/harness/.claude/skills/bytecode-vm-design in revfactory/claude-code-harness) into .agents/skills/bytecode-vm-design in your project. Codex loads it when a task matches its description.
Can I use Bytecode Vm Design in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add revfactory/claude-code-harness --skill bytecode-vm-design -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/bytecode-vm-design, .gemini/skills/bytecode-vm-design, .github/skills/bytecode-vm-design and .opencode/skills/bytecode-vm-design in your project.
What does Bytecode Vm Design need to run?
SKILL.md names no scripts, command-line tools or credentials: Bytecode Vm Design is instructions for the agent only.
Does Bytecode Vm Design access the network?
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.
Is Bytecode Vm Design safe to install?
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.
What licence does Bytecode Vm Design use?
No licence was found for Bytecode Vm Design or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Bytecode Vm Design use?
About 463 tokens (SKILL.md is roughly 1.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1k tokens, read only when the agent opens those files.
