An engineer from Ant Group named Chen Cheng reverse-engineered Claude Code 2.1.81 and discovered that its tool invocation requires passing through a four-layer decision pipeline to ensure safety review. The classifier design prioritizes cost and latency, monitors multiple risk categories, and includes allowlist exceptions and circuit breaker mechanisms. Meanwhile, the frequency of behavioral prompt injection is finely controlled to ensure efficiency and stability.

Ant Group engineer Chen Cheng reverse-engineered Claude Code 2.1.81 source code, revealing its Auto Mode decision-making mechanism. This mechanism employs a four-layer decision pipeline to determine tool invocations, only calling an independent AI classifier for security review when the first three layers cannot make a determination. The classifier design focuses on risk monitoring, featuring a circuit breaker mechanism and behavior prompt injection frequency controls.

Open source AI coding tool OpenCode's founder Dax Raad announced that due to receiving legal requirements from Anthropic, all Anthropic-related integrations, including relevant plugins and prompt files, will be removed in version 1.3.0. Despite attempting to communicate with Anthropic to support developer freedom of choice, the effort was unsuccessful. OpenCode is currently one of the most popular open source AI coding tools, with over 126,000 GitHub stars.

Users discovered that Tencent SkillHub automatically injects a system prompt during installation that instructs prioritizing SkillHub's features, causing continuous token consumption for users. Source code analysis reveals it functions merely as a prompt injector with no actual business logic, prompting users to express strong dissatisfaction and label it as malicious software.

CoinFello released the open-source skill OpenClaw on March 12, allowing AI agents to securely connect to MetaMask and execute on-chain transactions without accessing user private keys. The skill is built on ERC-4337 and ERC-7710, enabling users to grant minimal permissions to avoid prompt injection attack risks and supporting various on-chain functionalities.
