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.
# SVA Assertions Skill ## Overview Expert skill for SystemVerilog Assertions (SVA) development, enabling formal property specification and verification for FPGA designs. ## Capabilities - Write concurrent and immediate assertions - Create property specifications and sequences - Implement coverage properties (cover property) - Create assume properties for formal verification - Debug assertion failures with cause analysis - Generate assertion bind files - Optimize assertion performance - Integrate assertions with formal tools ## Target Processes - sva-development.js - constrained-random-verification.js - uvm-testbench.js - verilog-systemverilog-design.js ## Usage Guidelines ### Assertion Types - **Immediate Assertions**: Use for procedural checks within always blocks - **Concurrent Assertions**: Use for temporal properties across clock cycles - **Cover Properties**: Use for functional coverage collection - **Assume Properties**: Use for formal verification constraints ### Best Practices - Use `$rose`, `$fell`, `$stable` for edge detection - Apply `disable iff` for reset handling - Use `|->` for overlapping implication, `|=>` for non-overlapping - Create reusable sequences for common

What does the sva-assertions skill do?
Specialized skill for creating and debugging SystemVerilog assertions for FPGA verification
How do I install it?
Run `npx skills add a5c-ai/babysitter --skill sva-assertions --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.
