The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill's verification scripts download and install the mitata benchmarking library (version 1.0.34) from the npm registry. This is a standard and well-known tool in the JavaScript performance community and is used as intended for the skill's purpose.
[COMMAND_EXECUTION]: The skill utilizes spawnSync to run performance tests in separate processes. This is a recommended practice in performance engineering to prevent 'type feedback pollution' where different code versions affect each other's execution speed in the same process.
[DYNAMIC_EXECUTION]: The skill uses Worker threads and node:inspector sessions to perform accurate CPU and memory profiling. These are standard features of the Node.js and Bun runtimes for diagnostic and performance work.
[INDIRECT_PROMPT_INJECTION]: The skill is designed to ingest and execute JavaScript workloads to profile their performance.
Ingestion points: The skill takes JavaScript code snippets and reproduction scripts provided by the user.
Boundary markers: The skill instructs the use of equivalence oracles to ensure optimized code matches baseline behavior.
Capability inventory: The skill uses child process execution, worker threads, and file system access to temporary directories for profiling logs and snapshots.
Sanitization: The skill implements process isolation to bound the execution of profiled code.
