Specialized skill for finite state machine design and optimization in FPGAs
npx skills add a5c-ai/babysitter --skill fsm-design --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.
# FSM Design Skill ## Overview Specialized skill for finite state machine (FSM) design and optimization, ensuring robust and efficient control logic implementation in FPGA designs. ## Capabilities - Design Moore and Mealy state machines - Apply state encoding (one-hot, binary, Gray) - Implement illegal state recovery - Generate state diagrams and transition tables - Optimize FSM for area or speed - Apply safe FSM coding patterns - Debug FSM behavior with assertions - Handle FSM with multiple clock domains ## Target Processes - fsm-design.js - rtl-module-architecture.js - vhdl-module-development.js - verilog-systemverilog-design.js ## Usage Guidelines ### FSM Types - **Moore Machine**: Outputs depend only on current state - **Mealy Machine**: Outputs depend on state and inputs - **Registered Outputs**: Mealy with registered outputs for timing ### State Encoding - **One-Hot**: Fast, low combinational logic, more flip-flops - **Binary**: Compact, minimal flip-flops, more logic - **Gray**: Useful for CDC, single-bit transitions - **Custom**: For specific optimization requirements ### Safe FSM Patterns - Explicit default state in case statements - Illegal state detection and recovery -

What does the fsm-design skill do?
Specialized skill for finite state machine design and optimization in FPGAs
How do I install it?
Run `npx skills add a5c-ai/babysitter --skill fsm-design --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.
