fix(desktop): make image paste work in remote and cloud workspace terminals - #6692
Merged
Merged
Conversation
The .superset/attachments directory and its filename rules were reimplemented in three places, two of which (terminal-adapter.ts and agent-launch-request.ts) had to produce byte-identical names because one writes the files and the other renders their paths into the prompt -- kept in sync only by a comment. Move the constant and naming helpers into @superset/shared/workspace-attachments and point the adapter, the prompt renderer, the mobile composer, and buildLaunchSpec at it. Behavior-preserving except two edges, both moving writer and renderer in lockstep: dotfiles now dedupe as .bashrc_1 instead of _1.bashrc, and a generated name colliding with a real file suffixes instead of incrementing N.
…minals
Pasting an image into a terminal forwards Ctrl+V and lets the TUI read
the OS clipboard -- of the machine the PTY runs on. For a workspace on
another host (relay-reached machine, cloud sandbox) that clipboard never
holds the user's screenshot, so the paste silently did nothing (Codex
surfaces "Failed to paste image").
Fix renderer-side, since deployed sandboxes bake their host-service at
image build and never update: TerminalPane registers a per-terminal
imagePasteOverride (plumbed through the runtime registry like link
handlers) for workspaces whose hostId isn't this machine's. The override
ships the clipboard bytes over the existing filesystem.writeFile
(base64) into the shared .superset/attachments/ worktree dir and pastes
the worktree-relative path, matching the agent-launch and mobile
composer convention. The directory self-ignores via a .gitignore ("*")
so attachments never dirty git status, and writes are create-only,
probing _1/_2 suffixes so a repeat paste never overwrites a path an
earlier prompt referenced. Drag-dropping plain files onto a remote
terminal reroutes through the same upload (local paths mean nothing
there); local workspaces keep the Ctrl+V forward.
Remote detection reads machineId + the host-workspaces list rather than
useWorkspaceHostTarget, which mints sandbox access credentials per
consumer and would multiply the broker loop across long-lived panes.
Verified over CDP against a real relay-routed second host: before the
fix a real Cmd+V pasted nothing; after, the path lands in the prompt,
the bytes are cksum-identical on the remote side, a second paste probes
to image_1.png, git status stays clean, and a local workspace still
forwards Ctrl+V unchanged.

- Around line 538-545: Update the TerminalPane drop handler’s allPlainFiles
check to feature-detect item.webkitGetAsEntry before invoking it, matching the
guard used by collectDroppedEntries; when unsupported, allow the existing
path-based fallback to run instead of throwing.
- Around line 355-373: The isRemoteHost calculation must not classify a missing
workspace as remote when the local workspace list is unavailable or
unsuccessful. Update the hostWorkspaces readiness check to require a successful
local-host list response, while retaining remote classification for
cloud-sandbox workspaces absent from a successfully loaded list and preserving
the existing machineId comparison.
In `@packages/shared/src/workspace-attachments.ts`:
- Around line 26-27: Update the attachment-name sanitization logic to return
null when the sanitized value is exactly "." or "..", while preserving the
existing fallback for empty or whitespace-only results and allowing other
sanitized names.
- Around line 70-74: Update the attachment-name collision logic around
attachmentNameWithSuffix to normalize candidate names consistently before
checking or adding input.used entries, so differently cased filenames collide on
case-insensitive worktrees while preserving the returned display name. Add a
regression test covering names such as image.png and Image.png.

Review follow-ups on #6692: - sanitizeAttachmentFileName rejects "." and ".." (they name the directory or its parent, not a file) and assignAttachmentFileName dedupes case-insensitively so a same-batch image.png / Image.png pair can't silently collapse to one path on APFS/NTFS. - uploadPastedFiles refuses files over 50MB and batches over 200MB before reading any bytes (same caps as the agent-launch writer) with a toast-ready message -- an accidentally pasted multi-GB Finder file would otherwise be FileReader-read and base64'd in renderer memory. - handleDrop guards webkitGetAsEntry before calling it. At the cap, read+base64 of 50MB measures ~13ms; a typical 5MB screenshot ~1ms. The text-paste hot path is untouched.

Image paste forwards
\x16and lets the TUI (Claude Code, Codex) read the OS clipboard — of the machine the PTY runs on. A remote host or sandbox never holds the user's local screenshot, so the paste silently did nothing (Codex shows "Failed to paste image"). Users hit this on every remote/cloud workspace.How It Works
TerminalPaneregisters a per-terminalimagePasteOverridethrough the runtime registry (same pattern as link handlers; survives runtime eviction) when the workspace'shostIdisn't this machine's — a cloud sandbox has no host row at all, so "list ready and no row" also counts as remote.Files, writes them via the existingfilesystem.writeFile(base64) into<worktree>/.superset/attachments/— the same directory agent-launch attachments and mobile composer attachments use — and pastes the shell-escaped worktree-relative paths..gitignorecontaining*, create-only) so attachments never dirty git status; this also covers launch/mobile attachments, which previously showed as untracked._1/_2suffixes against the real directory, so a repeat paste never overwrites a file an earlier prompt referenced (the batch-scoped dedupe in launch/mobile can't see prior batches).Manual QA (done — verified over CDP against the real app)
Stood up a genuinely remote target in dev: a second standalone host-service with a distinct machine identity, registered against the dev API and local relay, and a session workspace created on it through the actual new-workspace UI (Blaxel keys in dev are placeholders, so a real sandbox wasn't reachable;
