Expert skill for bytecode virtual machine design including instruction set design, dispatch mechanisms, and stack/register architectures
npx skills add a5c-ai/babysitter --skill bytecode-vm --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Bytecode VM Skill ## Overview Expert skill for bytecode virtual machine design including instruction set design, dispatch mechanisms, and stack/register architectures. ## Capabilities - Design bytecode instruction sets - Implement stack-based vs register-based VMs - Implement efficient dispatch (switch, computed goto, threaded) - Design compact bytecode encoding - Implement bytecode verification - Handle exception handling in bytecode - Design inline caching for dynamic dispatch - Implement bytecode serialization/deserialization ## Target Processes - bytecode-vm-implementation.js - interpreter-implementation.js - jit-compiler-development.js - repl-development.js ## Dependencies VM implementation literature (Crafting Interpreters, Programming Language Pragmatics) ## Usage Guidelines 1. **Architecture Selection**: Choose stack-based for simplicity, register-based for performance 2. **Dispatch Mechanism**: Use computed goto/threaded dispatch for hot loops 3. **Encoding**: Design compact bytecode encoding to improve cache locality 4. **Verification**: Implement bytecode verification for security and debugging 5. **Inline Caching**: Add inline caching for polymorphic call sites ## Out

What does the Bytecode VM skill do?
Expert skill for bytecode virtual machine design including instruction set design, dispatch mechanisms, and stack/register architectures
How do I install it?
Run `npx skills add a5c-ai/babysitter --skill bytecode-vm --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From a5c-ai/babysitter, a repository with 1,642 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
