claude-code - 💡(How to fix) Fix [Bug] /effort command applies globally instead of per-session [1 comments, 2 participants]

[{"error":"Error: NON-FATAL: Lock acquisition failed for /home/sjunot/.local/share/claude/versions/2.1.118 (expected in multi-process scenarios)\n at ii$ (/$bunfs/root/src/entrypoints/cli.js:2758:2177)\n at R46 (/$bunfs/root/src/entrypoints/cli.js:2758:1257)\n at processTicksAndRejections (native:7:39)","timestamp":"2026-04-23T21:02:09.785Z"}]

TL;DR

The issue may be resolved by modifying the /effort command to only set the effort level for the current session, rather than all sessions.

Guidance

• The error message suggests a lock acquisition failure, which could be related to the /effort command affecting multiple sessions simultaneously.
• To verify the issue, try running the /effort command in a single session and check if the effort level is set correctly.
• To mitigate the issue, consider modifying the command to accept a session-specific parameter or flag to limit its scope.
• Investigate the cli.js file, specifically line 2758, to understand how the /effort command is implemented and how it interacts with session management.

Notes

The provided error message and code snippet are not directly related to the /effort command, but rather indicate a potential issue with lock acquisition in a multi-process scenario.

Recommendation

Apply workaround: Modify the /effort command to accept a session-specific parameter or flag to limit its scope, as this may help resolve the issue without requiring a full version upgrade.
