🔬 New AI Craft
1. Ponytail-improved teaches AI agents to be the "laziest senior dev"
An open-source project that trains AI agents to write the least code possible — "the best code is the code you never wrote." Unlike the Agent Plan mode's exhaustive, systematic approach, this promotes an adversarial mindset against over-engineering, directly complementing the tendency of plan-driven development to produce unnecessary work.

2. Handbook.md benchmark: long policy documents fail to reliably govern agents
A new arXiv paper introduces HANDBOOK.md, a 65-task benchmark testing whether long policy documents (20-124 pages) actually constrain agent behavior over extended tool-use horizons. Results show they don't — a direct challenge to the approach of relying on system prompts to control agent behavior.

3. AI worms can self-propagate through Copilot for Word
Research demonstrates how cross-domain prompt injection attacks (XPIAs) extend from single-interaction compromise to self-propagating worms across trusted document workflows, disclosed through a 144-day coordinated process with Microsoft MSRC. Raises new security concerns for AI-assisted development — injection attacks could propagate through code comments too.

4. autodev-studio: fully autonomous multi-agent SDLC pipeline
Describe a feature in plain English and AI agents handle scoping, coding, testing, code review, and PR submission end-to-end. Extends beyond Agent Plan's implementation focus to cover the full software development lifecycle.
