# test(integration): e2e coverage for IDE context tag stripping (\#1423)

`fa6de74`→[main](/content/gh/entireio/cli/commits/main/index.html)·

Drives the real user-prompt-submit hook with an <ide_opened_file> block and
asserts the stored session LastPrompt (title/prompt display) contains only the
user's text. Fails against the pre-fix lifecycle.go, passes with it.

// TestIssue1423_IDEContextTagStrippedFromSessionPrompt is a full-flow
// reproduction of #1423: Claude Code inside the VS Code extension prepends an
// <ide_opened_file> context block to the prompt, which leaked verbatim into the
// session/checkpoint title and prompt display.
//
// It drives the real user-prompt-submit hook binary with such a prompt and then
// reads the stored session state's LastPrompt (the value used for the session
// title / prompt display) — it must contain only what the user typed.
