Publicly Shared Claude Conversations Expose Embedded API Keys and Secrets to Search Engines
Publicly shared Claude chat URLs (`claude.ai/share`) are being actively indexed by search engines like Google. Developers sharing conversation transcripts have inadvertently leaked API keys, credentials, and confidential codebase fragments.
Why it matters. Engineers using Claude share links must audit active shared chats to prevent sensitive key exposure.

SHACKLE Releases SP-1.0 Circuit Breaker Specification to Prevent AI Agent Loops
SHACKLE introduced SP/1.0, an open-source specification and runtime daemon designed to act as a circuit breaker for autonomous AI agents. By executing deterministic checks against budget limits, tool repetition counters, and error amplification signals, it prevents rogue agents from burning thousands of dollars in retry loops.
Why it matters. Autonomous AI agents can easily get stuck in expensive retry loops, draining API budgets in minutes. SHACKLE provides a critical mediation layer to enforce safety limits before actions are executed.
