bullish on Al tools. bearish on the hype. | engineer × creator @bytecodecrux

your /CLAUDE.md is probably too long.

frontier LLMs can follow ~150-200 instructions reliably. claude code's system prompt already uses ~50.

that leaves you ~100-150 before it starts ignoring everything.

not just the stuff at the bottom. all of it. uniformly.

[Mandy @bytecodecrux]

claude hitting me with the rate limit today, anyone else or am i the chosen one.

[Mandy @bytecodecrux]

good thing it's just the web, claude code is fine(as we speak).

[Mandy @bytecodecrux]

my favorite underrated command in claude code - /context

[Mandy @bytecodecrux]

@sama @gothburz FDEs can observe but can they refuse?

[Mandy @bytecodecrux]

@paulg confidence sure but also he already made the hard calls before the ama.

[Mandy @bytecodecrux]

@sama how do you enforce the 'human responsibility for use of force' principle in a classified environment where openai engineers can't audit every deployment in real time?

anthropic beefing with the pentagon and boris is here borisifying #borisify

[Boris Cherny @bcherny]

In the next version of Claude Code..

We're introducing two new Skills: /simplify and /batch. I have been using both daily, and am excited to share them with everyone.

Combined, these kills automate much of the work it used to take to (1) shepherd a pull request to production and (2) perform straightforward, parallelizable code migrations.

@cryptopunk7213 #borisify

[Mandy @bytecodecrux]

@fahd838_ yeah, this is how claude code works. i remember @bcherny saying /claude.md files load lazily, so it won't bloat anything. just keep root tight since that one always loads.

[Boris Cherny @bcherny]

In case it’s not clear in the docs:

- Ancestor https://t.co/pp5TJkWmFE’s are loaded into context automatically on startup
- Descendent https://t.co/pp5TJkWmFE’s are loaded *lazily* only when Claude reads/writes files in a folder the https://t.co/pp5TJkWmFE is in. Think of it as a special kind of skill.

We designed it this way for monorepos and other big repos, tends to work pretty well in practice.

here's the video btw https://t.co/bNgW34qSjW

[Mandy @bytecodecrux]

made a video about openclaw and this is what you get for being honest lol

[Mandy @bytecodecrux]

i regret making a youtube video on openclaw. period.

[Mandy @bytecodecrux]

@iruletheworldmo theo is so right on this. read a study a while back, frontier models start breaking past ~150 instructions and the system prompt already eats into that.

cut my /claude.md to ~30 lines and yeah, works way better.

4o image gen had me hooked when it dropped, thought that was the ceiling.

nah i was just sleeping on @grok

[Mandy @bytecodecrux]

i get it. the rivalry is real but steve and bill shared a stage while trying to bury each other. holding hands for 3 seconds isn't that hard. get your shit together.

[Yuchen Jin @Yuchenj_UW]

This is why Sam and Dario can’t hold hands.

Anthropic is on track to overtake OpenAI in revenue by mid-2026 if the trend continues according to @EpochAIResearch.

The power of brutal focus on coding and enterprise.

[Mandy @bytecodecrux]

claude my dear claude, sometimes you get on my nerves.

[Mandy @bytecodecrux]

@morganlinton been there

[Mandy @bytecodecrux]

the gap between people coding with AI and people who aren't isn't technical. it's a you had to be there thing

try explaining what changed to someone who hasn't. you just sound like you joined a cult and tbh they're not wrong.

[James Wang @draecomino]

I've followed tech for 25 years and I've never felt a larger gap between the ~1 million people using Codex/Claude and the rest of humanity.

[Mandy @bytecodecrux]

@forloopcodes they laid off the people who understood the code and replaced them with ai that doesn't understand it either. at least it's consistent
