Workflow for evaluating and refining agent debugging capabilities using designated test cases and Swarm principles. Use when evaluating subagent performance or creating benchmarks. Do not use for regular bug fixing.
Workflow for agent self-improvement via isolated execution, evaluation, and process refinement. Use when evaluating historical bugs or self-correcting skills. Do not use for new feature development.
Handles installation and configuration of clangd-mcp for V8. Use when clangd-mcp is missing or needs configuration for the current workspace. Do not use for general C++ editing.
Running benchmarks with Crossbench.
Analyzes recent commits and uses a smart AI subagent to check if they invalidate any documentation in docs/.
Evaluates JavaScript using the official ECMAScript specification

| description | How to use jsvu for cross-engine testing. |
Use jsvu to install and test across multiple JavaScript engines (e.g., v8, spidermonkey, javascriptcore, chakra).
For non-interactive installation and updating of specific engines on Linux, run:
npx jsvu --os=linux64 --engines=v8,spidermonkey,javascriptcore
You can customize the --engines flag with the engines you wish to test (e.g., v8,v8-debug,spidermonkey,javascriptcore,graaljs).
Once installed, the engines are available in ~/.jsvu/bin/. You can run them directly:
~/.jsvu/bin/v8 my_test.js
~/.jsvu/bin/spidermonkey my_test.js
~/.jsvu/bin/javascriptcore my_test.js
This allows you to easily cross-reference behaviors and bugs against other major JS engines.
