1/3 Just got a nice DM from a big enterprise customer using Claude Code in one of the world's biggest codebases Here's how we made @-mentions 3x faster in large enterprise codebases 🧵2/3 After a few hours, I had a PR. The results were solid -- P99 got 3x faster after porting to TypeScript!3/3 The wins came from three places: 1. Pre-computing upfront in a clever way that doesn't block the main thread 2. Avoiding NAPI overhead for small result sets 3. Iteratively asking Claude to find perf improvements for faster file search
1/5 1/ Did you know Claude Code has a mobile app? Personally, I write a lot of my code from the iOS app. It's a convenient way to make changes without opening a laptop. Download the Claude app for iOS/Android > Code tab on the left.2/5 9/ Use /btw for side queries I use this all the time to answer quick questions while the agent works3/5 8/ Fork your session People often ask how to fork an existing session. Two ways: 1. Run /branch from your session 2. From the CLI, run claude --resume <session-id> --fork-session4/5 14/ Use --agent to give Claude Code a custom system prompt & tools Custom agents are a powerful primitive that often gets overlooked. To use it, just define a new agent in .claude/agents, then run claude --agent=<your agent's name> https://code.claude.com/docs/en/sub-agents5/5 12/ Use --bare to speed up SDK startup by up to 10x By default, when you run claude -p (or the TypeScript or Python SDKs) we search for local CLAUDE.md's, settings, and MCPs. But for non-interactive usage, most of the time you want to explicitly specify what to load via --system-prompt, --mcp-config, --settings, etc. This was a design oversight when we first built the SDK, and in a future version, we will flip the default to --bare. For now, opt in with the flag.
RT Lydia Hallie ✨ Claude Code now supports an `if` field in hooks It uses permission rule syntax to filter when a hook runs, which is useful when you want a hook on some bash commands but not every single one! Original tweet: https://x.com/lydiahallie/status/2037573738670297583

RT Felix Rieseberg Today's ship: Projects in Cowork! Built in memory across tasks is super useful, as is having a shared folder & connections setup for a group of tasks. Original tweet: https://x.com/felixrieseberg/status/2035066361719005294
RT Santiago Claude Cowork is mind-blowing. I still cannot believe you can do this on your phone and then come back to your computer to a complete report on the best plane tickets to buy. I wonder where we'll be by the end of the year. Original tweet: https://x.com/svpino/status/2034609603619803592
RT Lydia Hallie ✨ Btw you can add `context: fork` to run a skill in an isolated subagent. The main context only sees the final result, not the intermediate tool calls It gets a fresh context window with CLAUDE.md + your skill as the prompt. The `agent` field even lets you set the subagent type! Original tweet: https://x.com/lydiahallie/status/2033603164398883042

RT Mike Krieger Claude is #1 in the App Store today — I want to say a huge thank you to all of our new (and existing!) users for the support. We’re working hard for you, please share your thoughts and feedback along the way. Original tweet: https://x.com/mikeyk/status/2027882977422610586
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.
RT SemiAnalysis 4% of GitHub public commits are being authored by Claude Code right now. At the current trajectory, we believe that Claude Code will be 20%+ of all daily commits by the end of 2026. While you blinked, AI consumed all of software development. Original tweet: https://x.com/SemiAnalysis_/status/2027443723362042308

1/6 2/ Use worktree mode in the Desktop app If you prefer not to use terminal, head to the Code tab in the Claude Desktop app and ☑️ worktree mode https://code.claude.com/docs/en/desktop-quickstart#install2/6 1/ Use claude --worktree for isolation To run Claude Code in its own git worktree, just start it with the --worktree option. You can also name your worktree, or have Claude name it for you. Use this to run multiple parallel Claude Code sessions in the same git repo, without the code edits clobbering each other. You can also pass the --tmux flag to launch Claude in its own Tmux session.3/6 Introducing: built-in git worktree support for Claude Code Now, agents can run in parallel without interfering with one other. Each agent gets its own worktree and can work independently. The Claude Code Desktop app has had built-in support for worktrees for a while, and now we're bringing it to CLI too. Learn more about worktrees: https://git-scm.com/docs/git-worktree4/6 4/ Custom agents support git worktrees You can also make subagents always run in their own worktree. To do that, just add "isolation: worktree" to your agent frontmatter5/6 3/ Subagents now support worktrees Subagents can also use worktree isolation to do more work in parallel. This is especially powerful for large batched changes and code migrations. To use it, ask Claude to use worktrees for its agents. Available in CLI, Desktop app, IDE extensions, web, and Claude Code mobile app.6/6 5/ Also available for non-git source control If you're a Mercurial, Perforce, or SVN user, define worktree hooks to benefit from isolation without having to use Git

Just tried Claude Cowork now… and I seriously regret not using it sooner. This thing is actually insane/crazy good.
Thanks for having me on the pod @garrytan! I joined a YC startup back in the early days of YC in 2011. It’s crazy how much has changed for founders building today vs back then. Small teams (and their Claudes) can do so much now!
