Can ShardStitch recover a stuck Cursor Composer chat?

ShardStitch can read persisted Cursor conversation state locally in read-only mode and combine it with verified repository state. It cannot recover model output that Cursor never persisted or applied.

Cursor Composer stuck on Generating or Taking longer than expected?

Q: What should I do when Cursor says Taking longer than expected?

Preserve the current Git state and copy the Request ID. Try one short continue prompt if the stream merely paused. If it remains stuck, use Cursor's network diagnostics, HTTP/2 workaround, or index resync before moving the task to a fresh Composer chat.

Q: Will restarting Cursor erase files already written?

Restarting Cursor does not normally erase files already written to the workspace, but incomplete streamed output or unapplied edits may not exist on disk. Inspect Git status and the working diff before another agent edits the project.

Protect the files that already changed, identify whether the request, network path, index, or one conversation is stuck, then continue from a clean verified state.

Do this first: run git status --short and git diff --stat, save the Request ID from the chat menu, and note the last file Cursor changed. Do not delete Cursor data or edit its database to fix an active request.

Wait, continue, or restart?

Output is still moving

Wait while tokens, terminal output, or file changes are still appearing. The status alone does not prove that the request is wedged.

The stream stopped mid-line

Send one short continue prompt. Cursor users have reported that this can release the known Taking longer than expected pause. Do not repeat it indefinitely.

Nothing changes

Preserve the Request ID and working tree, then test a fresh Composer chat with one tiny request. This separates a single broken conversation from a wider network or IDE problem.

Every new chat hangs

Run Cursor Network Diagnostics. Cursor support also recommends testing with HTTP/2 disabled and resyncing the codebase index.

Use the failure boundary to choose the fix.

Preserve what reached disk. Record changed files, untracked files, current branch, recent commands, and the smallest verification step. A faded or incomplete line in Composer is not proof that the code was written.

Capture Cursor's evidence. Open the chat menu and copy the Request ID before closing the conversation. If the issue needs support, the Request ID is more useful than a screenshot of the spinner alone.

Test one fresh Composer. Ask for a read-only summary of one file. If the fresh chat works, move the task with a compact handoff instead of continuing to feed the damaged conversation.

Test the network path. In Cursor Settings, run Network Diagnostics. Compare a tiny read-only request in an empty folder with the failing workspace. If the failure also occurs there and points to a network issue, try "cursor.general.disableHttp2": true in User Settings JSON, restart Cursor, and repeat the same request. Treat this as a diagnostic experiment, not a universal fix; restore the previous setting if it does not help.

Resync only when indexing is implicated. Use Cursor Settings, Indexing and Docs, Codebase Indexing, then Resync Index. An indexing fix is appropriate when retrieval or project awareness is also failing; it is not a universal fix for every stalled response.

In the February 2026 Cursor support discussion, support recommended network diagnostics and an HTTP/2 setting experiment, but users also reported that these steps did not resolve their stalls. Record your Cursor version, Request ID, diagnostic result, and whether a new empty-folder chat fails before escalating. Source reviewed September 5, 2026; this is not a locally reproduced fix.

If one old chat will not load.

A request stuck while streaming and a conversation stuck on Loading Chat are different failures. Cursor persists Composer history locally, but direct database editing is a high-risk troubleshooting step. Before any maintenance, fully close Cursor and copy the database to a separate backup location.

Windows: %APPDATA%\Cursor\User\globalStorage\state.vscdb
macOS:   ~/Library/Application Support/Cursor/User/globalStorage/state.vscdb
Linux:   ~/.config/Cursor/User/globalStorage/state.vscdb

Keep the original untouched. Start with Cursor's supported diagnostics and a fresh chat. Database repair instructions from forum posts may apply to a particular Cursor version or Loading Chat failure, but they should not be treated as the first fix for a normal Generating hang.

What ShardStitch can recover from Cursor.

ShardStitch reads persisted Cursor conversation state locally in read-only mode. It combines the recovered messages with repository evidence such as Git diff, changed files, recent commits, local notes, failed checks, and the next verification action. The continuation packet can return to a fresh Cursor chat or move to another supported coding tool.

Recoverable

Persisted conversation messages, files already written, repository changes, recent commits, local notes, and verification evidence.

Not recoverable

Tokens that never reached Cursor, streamed text that was never persisted, and unapplied code that does not exist in the database or working tree.

Trust boundary

Conversation text is context. Git state, file contents, command output, and tests are evidence. ShardStitch keeps those categories separate.

Give the fresh chat a bounded continuation.

Goal:
Files already changed:
Verified working behavior:
Exact Cursor failure and Request ID:
Attempts that did not work:
Next safe action:
Verification command:

Ask the new Composer to inspect the current diff before editing. This prevents a clean chat from repeating work that the stuck run already wrote.

If the terminal command is the blocker.

If Cursor is not just generating but waiting on a shell command, use the Cursor terminal command stuck guide. It covers interactive prompts, watchers, servers, hidden terminal output, and bounded retries.

Sources and verification.

Cursor staff describe Taking longer than expected as a known issue and recommend disabling HTTP/2, resyncing the project index, running Network Diagnostics, and preserving the Request ID. Older Cursor reports also show that opening a new Composer can isolate a conversation-specific hang. ShardStitch's read-only Cursor recovery path and role mapping are covered by the current product test suite.

FAQ.

What should I do when Cursor says Taking longer than expected?

Preserve the diff and Request ID. Try one short continue prompt. If it stays stuck, test a fresh chat, run Network Diagnostics, and use Cursor's HTTP/2 or index-resync workarounds when the evidence points to those layers.

Will restarting Cursor erase files already written?

Files already written normally remain on disk. Incomplete streamed output or unapplied edits may not. Inspect the working tree before another agent edits anything.

Can ShardStitch recover the conversation?

It can recover conversation messages that Cursor persisted locally and combine them with verified repository state. It cannot reconstruct output that was never saved.

Scope note: Cursor failure causes vary by version, model, network, extension state, and workspace. Diagnose the layer before changing local state.
