dsh-input-history

Input history switcher for the DeepSeek Harness (DSH) composer.

Every submitted prompt — text plus attachment bytes — persists locally (localStorage metadata + IndexedDB blobs, newest first, capped at 50 entries; the oldest is dropped together with its blobs). With an empty composer, ↑ recalls the previous entry and continues to older ones, ↓ goes back; going past the newest clears the composer and ends the cycle. Any real edit ends the switching session, and a non-empty user-authored draft is never overwritten by accident.

Restore fidelity

Restored entries go through the product's own draft pipeline (conversation.createDrafts + the session input shell's setDraft/addAttachments actions), so:

• images come back as real thumbnails (fresh object-URL previews),
• files restart the background upload like a hand-picked attachment,
• @references in the text are preserved verbatim.

Entries whose blobs are gone restore text-only.

Install

dsh plugin --profile web add dsh-input-history
# restart dsh web / the desktop app (bundle layer applies at boot)

How it works

• Capture — wraps ConversationController.prototype.sendSession (the single funnel for composer submissions) and snapshots the ordered draft attachments (live File objects) before the original send consumes them. Capture is async and failure-swallowing: storage problems never break sending.
• Storage — metadata in localStorage["dsh-input-history:entries:v1"], bytes in IndexedDB dsh-input-history/blobs (key <entryId>:<index>).
• Active session — tracked via a conversation.composer.dock slot whose inject(sessionId) runs for the mounted composer, falling back to the most recently updated session.

Configuration

None. Zero npm dependencies.
