## Industry News
- **xAI acquires Cursor for $60B**: SpaceX/xAI offered $10B upfront collaboration fee plus $60B acquisition rights, shelving Cursor's $2B fundraise. Microsoft had also evaluated but walked away. [link](https://x.com/pratyush_r8/status/2047326842819109372)
- **Anthropic locks 3.5GW TPU capacity through 2027**: Via Broadcom deal with Google, while Amazon commits $5B more to Anthropic ($13B total) with $100B+ AWS spend over decade. Infrastructure is now the moat. [link](https://x.com/pratyush_r8/status/2047326842819109372)
- **UAE launching AI-driven government**: 50% of government sectors will be AI-driven within two years under presidential directive, replacing traditional bureaucracy with autonomous systems. [link](https://x.com/HHShkMohd/status/2047325975)
- **GPT-5.5 and GPT-5.5 Pro spotted**: Both models appeared on OpenRouter with date 2026-04-23, and OpenAI removed "latest frontier" label from GPT-5.4 in Codex model list. [link](https://x.com/JasonBotterill/status/2047287040715436187)
- **Bitwarden CLI compromised in supply chain attack**: Version 2026.4.0 included malicious code after attackers abused GitHub Actions token, part of ongoing Checkmarx campaign. [link](https://x.com/TheHackersNews/status/2047327801485971799)

## Tips & Techniques
- **Ask agents about missing context when stuck**: When an agent isn't behaving as expected, directly ask "Are you missing any context?" - simple but effective prompt technique. [link](https://x.com/omarsar0/status/2047328075528983006)
- **State-first programming for AI agents**: Ground agents in modeling state rather than just chaining function calls - restores the lost abstraction boundary for building reliable complex software. [link](https://x.com/freddie_spirit/status/2047315890891329988)
- **Configure Claude Code auto mode with $defaults**: New v2.1.118 includes "$defaults" in autoMode.allow/soft_deny/environment settings - without it your custom rules replace built-in blocklist instead of adding to it. [link](https://x.com/dani_avila7/status/2047321755685962039)

## New Tools & Releases
- **GStack from YC's Garry Tan**: Open-source toolkit that turns Claude Code into an AI engineering team with multi-agent coordination capabilities. [link](https://x.com/ycombinator/status/2047329040399266039)
- **NanoClaw v2 with Vercel**: Complete rebuild enabling agent-to-agent communication, human-in-the-loop approvals, and support for 15 messaging platforms. [link](https://x.com/Scobleizer/status/2047325886509465924)
- **Tencent Hy3-preview released**: 295B total params, 21B active per token, 256K context window with 40% efficiency gain - built for agents with code/search/reasoning focus. [link](https://x.com/manna56749964/status/2047326667362963639)
- **Google agents-cli open-sourced**: CLI and skills package to turn existing AI coding assistants into "agent engineers" specialized for building/evaluating/deploying agents on Google Cloud. [link](https://x.com/El_Capitano_O/status/2047326093464441110)
- **OpenAI releases 1.5B privacy filter model**: Open-weights model for PII detection, ported to MLX runs 24-33x faster on Apple Silicon. Apache 2.0 licensed. [link](https://x.com/altryne/status/2047327388678435033)
