I love zoxide a lot for navigating monorepos, but have found it confusing when I accidentally change repos without realizing it. So I made a wrapper using @AmpCode to only consider matches within the current repo!

@claudeai @AnthropicAI OMG I FIGURED IT OUT! The problem isn't the model - apparently there's a bug in @claudeai where enabling Research mode does not make the tool available in the first chat message. @AnthropicAI pls fix

@claudeai @AnthropicAI I wonder why @claudeai hasn't noticed a big reduction in launch_extended_search_task usage?.

@claudeai @AnthropicAI Confirmed that when you start a new chat with Research mode selected, it has compase_mode set to null, but when you toggle it on an existing chat, it's setting compase_mode: advanced

@claudeai @AnthropicAI Is Claude Opus 4.1 just bad? I explicitly told it to use launch_extended_search_task and it ignored it:

@claudeai Interesting - apparently Claude Opus 4.1 does not follow it's own prompts: @claudeai @AnthropicAI are y'all aware of this?

@claudeai okay apparently you just have to insist it use research mode. It used to be automatic. Guess they don't want people using it?

Is @claudeai research mode broken? I'm getting the exact same results with/without Research enabled on Max 20x plan. Or is this just what Claude is like nwo?.

Noticed this because it's no longer asking for permission to run entire python scripts with uv like it always has in the past

The only thing that threw me off a bit is that you can't use .transform() in schemas within a codec

Zod 4.1 codecs make it sooo much easier to serialize custom types to JSON 😍

This was #2 in total compute time in my CI jobs the last 5 months, so this will save a decent chunk of CI time!

Migrated my main monorepo to typescript-go (tsgo) and type checking got 66% faster 😍 (27s -> 9s)
