Middleware for the sampling loop: check_tool_use() evaluates tool_use
blocks before execution (blocks dangerous bash commands, detects PII),
check_result() scans results before feeding back to Claude (redacts
PII/secrets).
- Local bash pattern matching for fast client-side blocking (rm -rf,
credential exfiltration, curl|bash)
- Server-side policy evaluation via mcp_check_input/output
- Connector type derivation: computer_use.{action} for computer tool,
computer_use.{name} for bash/text_editor
- CheckResult dataclass with allowed, block_reason, redacted_result
29 tests, 95% coverage on computer_use.py. Lint clean.
Ruff import ordering (isort) requires alphabetical module order. Moved computer_use import before langchain/langgraph.

Summary
ComputerUseGovernoris a middleware for Anthropic's Computer Use sampling loop. Drop it in at two points:check_tool_use(block)— evaluates tool_use blocks before executioncheck_result(name, result)— scans results before feeding back to ClaudeFeatures
