Claude Code v2.1.222 ·

Task output files use a memoized path and lazy directory creation

Task output files skip repeated path work and only create folders when actually writing.

What

Task output writing resolves its file path once per task and creates the containing directory only when the file is opened, replacing an upfront directory-creation step.

Details
  • <taskId>.output is resolved through a per-task path cache
  • The parent directory is created at open time with mkdir(dirname, { recursive: true })
  • The previous upfront directory creation helper was removed
  • The cache entry is dropped when the task output is flushed, cleared or cleaned up
Evidence

.output

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
