claude-cc is a tiny npm-installable bash wrapper around Claude Code that automatically finds and resumes the most recent Claude session for your current git branch when you launch it. It reads .claude/projects/ history, matches by branch name, and passes the --resume flag — or starts fresh if no prior session exists. Supports all native Claude CLI flags. Written in mostly bash with some JavaScript; zero external dependencies beyond Claude CLI and Python 3. Surfaced on Hacker News today, scratching a specific context-loss itch many Claude Code power users have.

Dirac is an open-source AI coding agent built by Dirac Delta Labs that shot to the top of TerminalBench-2 with a 65.2% score using Gemini Flash — while costing 64.8% less than competing agents. Forked from Cline and rebuilt with a performance-first architecture, it handles file modifications, multi-file refactoring, terminal commands, and browser automation through an approval-based workflow. What sets Dirac apart is its technical substrate: hash-anchored edits replace fragile line-number targeting with stable content hashes, AST-native processing understands language structure for TypeScript, Python, and C++, and multi-file batching reduces LLM roundtrips by processing several files per call. The result is a leaner context that preserves model reasoning quality without burning through tokens. Available as both a VS Code extension and an npm CLI, Dirac supports Anthropic, OpenAI, Google, Groq, and Mistral as backends. Its Apache 2.0 license and strong TerminalBench showing on the affordable Gemini Flash model make it a compelling pick for developers who want production-grade coding assistance without the per-token bill shock.
Reviewer scorecard
“This is the definition of a tool that should exist. Switching branches to fix a bug, then returning to your feature work, you always lose the conversation thread. claude-cc makes context persistence the default. It's tiny, it has no dependencies, and it does exactly one thing right. Every Claude Code user should have this aliased.”
“Topping TerminalBench-2 while being 64.8% cheaper is the kind of benchmark that actually matters to developers. The hash-anchored editing and AST-native approach fix the two most annoying failure modes of existing coding agents — wrong line edits and syntax-blind refactors.”
“This is a 50-line script masquerading as a tool. Anthropic will ship this natively in Claude Code within the next update cycle, at which point claude-cc becomes dead weight. Building a dependency on someone's weekend project for core workflow automation is poor risk management. Just alias the --resume flag yourself and move on.”
“It's a Cline fork with smart optimizations — not a ground-up rethink. TerminalBench-2 scores are reproducible only if you're running similar tasks; complex real-world codebases may tell a different story. Also, requiring your own API key still means real money.”
“The interesting signal here isn't the script — it's the demand. When a tiny utility for session resumption hits Hacker News and resonates, it means developers are spending significant time on persistent AI coding sessions across multiple branches simultaneously. That's a new workflow pattern that tooling hasn't caught up to yet.”
“The race to build the cheapest, most accurate coding agent is the real infrastructure play of 2026. Dirac's multi-provider support and lean context model are exactly the primitives that make agentic coding deployable at scale — not just on powerful machines.”
“I installed it in 30 seconds and it just worked. The fallback-to-new-session behavior is thoughtful — it never blocks you, it just tries to help. For non-developers who rely on Claude Code for writing or research workflows, this kind of friction reduction matters a lot. Simple tools that do one thing are often the most valuable.”
“The VS Code extension makes it approachable for designers who code. Approval-based workflows mean it won't silently rewrite your carefully named CSS classes. Worth trying if you've been burned by agents that act first and apologize later.”
