fix(cursor): resolve the cursor agent binary as \agent\ or \cursor-agent\ - #1257
fix(cursor): resolve the cursor agent binary as \agent\ or \cursor-agent\#1257asiqur-rahman wants to merge 2 commits into
agent\ or \cursor-agent\#1257Conversation
…ent` Cursor's official CLI installs as `agent` (curl https://cursor.com/install -fsS | bash -> ~/.local/bin/agent), while this codebase and older setups used `cursor-agent`. On hosts that only have `agent`, the provider reported "Cursor CLI not found or not installed" even though the CLI and login existed. Add server/shared/cursor-cli-path.ts which prefers an explicit CURSOR_CLI_PATH override, then whichever of cursor-agent/agent exists on PATH (cached), falling back to cursor-agent. Use it in the cursor auth provider, runtime, shell command builder, and the login modal (which now tries `cursor-agent login || agent login`). Co-authored-by: CommandCodeBot <noreply@commandcode.ai>

Escape CURSOR_CLI_PATH before building the shell command.
When CURSOR_CLI_PATH contains spaces, resolveCursorAgentCommand() returns the raw path, and handleShellConnection() passes it to bash -c or powershell.exe -Command. Both Cursor branches can fail. Quote the path for the active shell or pass executable arguments separately. Add launch and resume tests with paths that contain spaces.

Resolve executable commands instead of existing paths.
isExecutableOnPath uses existsSync, so a directory or non-executable cursor-agent can win before a usable agent candidate. The resolver also misses Windows PATHEXT targets such as agent.exe and then returns the unusable fallback. Use platform-aware lookup and test both cases.

The new server/shared/cursor-cli-path.ts was not in the boundaries/elements allowlist, so oxlint's boundaries/no-unknown failed on any import of it (the websocket shell service). Add it to the backend-shared-utils element pattern so backend modules may import it. Co-authored-by: CommandCodeBot <noreply@commandcode.ai>

Summary
Fixes the Cursor provider so it finds Cursor's real CLI. Cursor's official installer (
curl https://cursor.com/install -fsS | bash) puts anagentbinary on PATH, while this codebase hard-codedcursor-agent. On machines that only haveagent(fresh Linux installs, containers, CI), the provider reported "Cursor CLI not found or not installed" even when the CLI and a valid login existed.What changed
server/shared/cursor-cli-path.ts: resolves the Cursor agent command by preferring an explicitCURSOR_CLI_PATHoverride, then whichever ofcursor-agent/agentactually exists on PATH (probed once and cached), falling back tocursor-agentto preserve prior behavior.cursor-auth.provider.ts):checkInstalled()andcheckCursorLogin()now spawn the resolved command instead of the hard-codedcursor-agent.cursor-runtime.provider.js): session runs spawn the resolved command.shell-websocket.service.ts): the interactive Cursor shell / resume command uses the resolved command.ProviderLoginModal.tsx): Cursor login now runscursor-agent login || agent loginso it works whether the host has the old or new binary name.Verification
npm run typecheck— passes (server + frontend).agentbinary mounted on PATH, the Cursor provider status flips from "Cursor CLI not found or not installed" to "Not logged in", i.e. the CLI is now detected and its login state is evaluated.Notes
cursor-agent(older installs) andagent(current official installs) both resolve;CURSOR_CLI_PATHforces either for unusual layouts.agent login.Summary by CodeRabbit
