Unclear The lookup also depends on two further internal checks whose names are not known, so it is unclear whether it runs at all.

What

The Projects tool lets Claude search and write documents in a claude.ai Project. Several parts of it changed:

  • project_search results can now include images, as image blocks next to the text. Before, results were text only. Images are removed when a result is stored and put back when the result is remapped (restoreTransientForRemap).
  • project_search now takes a number from the switch tengu_pebble_harbor, held between 0 and 4. Before, it took only n. Nothing has been read about this switch.
  • tengu_lovely_rain alone now gates writing into the document in view, and tengu_lucky_nebula only gates the variant that writes by file path. Before, writing needed both. tengu_toasty_owl is unchanged. For both tengu_lovely_rain and tengu_lucky_nebula, the flag server returned off for this site's account and for the anonymous baseline, and no reading has been taken under this release.
  • Writes and deletes go through a new approval check.
  • Stream events gain an internal optional owed_rows field. It lists the IDs of project_doc_reads rows, which record Claude Code reading a claude.ai Project's documents.
  • After a turn whose attachments include project_doc_reads, Claude Code starts a lookup of hashes (fingerprints) of those documents. The environment variable CLAUDE_CODE_PROJECT_DOC_LOOK_TIMEOUT_MS sets how long the lookup may take, and on a timeout it gives up for the rest of the session. In headless mode (running without the interactive screen) the ID of the project_doc_reads attachment is also collected into a list.

Why

Claude can now get pictures, not just text, back from a project search. Whether each kind of write is available depends on a different server switch than before. If the document lookup slows you down, CLAUDE_CODE_PROJECT_DOC_LOOK_TIMEOUT_MS bounds it.
