Run doctor, output is minimax is OK
Update to latest claude, still the same

Before it was fine

I am testing out MiniMax 2.1 and made a fix for this (using MiniMax 😅) see PR.

Additionally found a related bug in the same update:

Issue: ReferenceError: GREP_TOOL_NAME is not defined

file:///~/.cc-mirror/minimax/npm/node_modules/@anthropic-ai/claude-code/cli.js:4576
assistant: [Uses `${H9}` tool with subagent_type=`${UI.agentType}` to find files that handle client errors instead of using `${xX}` or `${GREP_TOOL_NAME}` directly]
                                                                                                                                           ^

ReferenceError: GREP_TOOL_NAME is not defined

Root Cause: The system prompt contains ${GREP_TOOL_NAME} which references an undefined variable in Claude Code 2.1.1. This should be ${xX} instead (where xX is defined as "Grep" in minified code).

Workaround: Both instances (minimax and zai) work after restoring from cli.js.backup:

cd ~/.cc-mirror/minimax/npm/node_modules/@anthropic-ai/claude-code
mv cli.js cli.js.broken && cp cli.js.backup cli.js

This affects both minimax and zai configurations. PR #28 fixes EJ.has but may not address this additional undefined variable.

We shipped v1.6.6 (2026-01-18) which bumps Claude Code to 2.1.12. Can you update (npx cc-mirror update or re-create) and confirm whether the EJ.has / GREP_TOOL_NAME errors persist? If they do, please paste the full stack trace, OS, Node version, and cc-mirror version.

cc-mirror version.

How I can check version of the current CC mirror?
Nothing in --help

[numman-ali]

Ah actually that's incorrect of me

Can you simply run npx cc-mirror update

And let me know if it fixed it?

Or remove existing variants and add new ones

[Set27]

npx cc-mirror update

Using this update cc-mirror to latest version, doctor is OK, running minimax and sent message get:

Can you try remove the variant and then add a new variant?
