claude-code - 💡(How to fix) Fix [Feature Request] Expose reasoning effort and thinking level in statusLine stdin JSON [1 participants]

[{"error":"Error: NON-FATAL: Lock acquisition failed for /home/kim/.local/share/claude/versions/2.1.117 (expected in multi-process scenarios)\n at Dn$ (/$bunfs/root/src/entrypoints/cli.js:2756:2177)\n at tq6 (/$bunfs/root/src/entrypoints/cli.js:2756:1257)\n at processTicksAndRejections (native:7:39)","timestamp":"2026-04-22T13:39:18.245Z"},{"error":"Error: Request was aborted.\n at makeRequest (/$bunfs/root/src/entrypoints/cli.js:50:3448)\n at processTicksAndRejections (native:7:39)","timestamp":"2026-04-22T13:39:32.920Z"}]

TL;DR

To address the issue, modify the statusLine command to include the current reasoning effort and thinking level in the JSON payload received on stdin.

Guidance

• Review the settings.json file to understand how the effortLevel is persisted and how it differs from the live session value.
• Investigate the cli.js file, specifically lines 2756:2177 and 50:3448, to understand the lock acquisition failure and request abortion errors.
• Consider adding the current reasoning effort and thinking level to the statusLine stdin JSON payload, reflecting the live session value.
• Verify that the statusLine command can access and include the live session values for effort and thinkingLevel in the JSON payload.

Example

No code snippet is provided as the issue lacks specific implementation details.

Notes

The provided errors may be unrelated to the feature request, but rather indicate issues with lock acquisition and request handling in the cli.js file.

Recommendation

Apply workaround: Modify the statusLine command to include the current reasoning effort and thinking level in the JSON payload, as this directly addresses the feature request and may not require a version upgrade.
