Building a Claude Code Mod — Locking the Reply Language and a Finished Notice

A mod is a small add-on that bolts your habits onto Claude Code. Before writing one we counted what we actually repeat most.

Conversations counted
30 days · 2,195
‘Answer in Korean’ repeats
13
‘Continue’ repeats
67

Working with an AI, you end up saying the same things. We wanted numbers rather than a feeling, so we counted 2,195 conversations over 30 days: about 40 ‘is it done?’ checks, 13 ‘answer in Korean’, and 67 ‘continue’.

What the owner said

I’m tired of telling it to answer in Korean and asking if it’s finished. Make a machine do that.

So here is what I did

  1. Automatically attach a Korean-language rule to every prompt
  2. If an English answer comes back, re-ask exactly once (to prevent a loop)
  3. While working, show ‘N min · N tool calls’ next to the spinner
  4. When a reply ends, show ‘✅ Done 3:42 pm’ and usage in dim text
  5. Jobs longer than 10 minutes send a Telegram alert (can be switched off)
  6. Warn above the input box when the conversation passes 50% or the usage limit passes 70%
  7. Block frequent mishaps: opening Edge, resizing the Chrome window, and git add -A right after cd

What tripped us up

All 8 tests pass, and we confirmed the Korean rule is attached in a real window. The on-screen indicators (spinner, finished mark) are still being checked in daily use.

Plenty here is still unsolved. If you know a better way, say so — it gets read and answered.
