# Debugging Page JavaScript Use this skill when the task is about browser-side JavaScript behavior rather than navigation alone. ## Quick start - Use `eval` in the shell to print a value; in scripts `js` runs code and discards the result - Use `jsfile` for longer snippets or reusable helpers - Use collector scripts when the task needs structured console output over time ## Use this skill for - evaluating expressions in the page context - enabling and interpreting console output - capturing page errors or ad hoc telemetry - debugging page-side state during scripts or interactive sessions ## Read next - Console and JavaScript execution patterns: [references/console.md](references/console.md) - CLI-level command surface: [../operating-cdp-cli/SKILL.md](../operating-cdp-cli/SKILL.md)
