Continuous-Claude-v3

Least-privilege permissions

• Restrict API keys by scope: Only grant Claude Code agents access to the specific APIs and data they need for their task—never provide master keys or admin-level credentials. If an agent only needs to read customer names, don't give it write access to billing systems.
• Isolate data handoffs: When agents pass information to external tools (MCP connectors), explicitly whitelist what data gets transferred. Review each handoff point to ensure agents aren't accidentally sharing passwords, tokens, or customer records they shouldn't.
• Segment agent roles: Assign different Claude agents different permission levels based on their job. A customer service agent shouldn't have the same access rights as a financial reporting agent.
• Rotate credentials regularly: Change API keys, database passwords, and service tokens frequently—at least monthly—to limit the window of exposure if a ledger (the stored state) is compromised.

Network isolation

• Air-gap sensitive systems: Keep high-risk databases (payroll, healthcare data, credentials vault) on separate network segments that Claude Code agents cannot directly reach. Use secure APIs with authentication as the only connection point.
• Monitor outbound connections: Log and alert on any network traffic Claude agents initiate to unfamiliar domains or internal systems they shouldn't contact. Unusual outbound calls could signal a compromised agent or injected malicious instructions.
• Use VPN or private endpoints: Route agent-to-tool communication through encrypted, private network connections rather than the public internet to prevent eavesdropping on sensitive context data.

Monitoring

• Audit ledger access and content: Log every time the state storage (ledger) is read, written, or flushed. Periodically review logs to spot unusual access patterns or sensitive data that shouldn't be there.
• Track context window handoffs: Record what data moves between agents and external tools at each step. Alert if an agent tries to pass unusually large payloads or restricted data types.
• Test for residual data: After each agent run, verify that the context storage is truly cleared. Perform spot checks to confirm no passwords, API keys, or personal information lingers in the system.
• Version-check the tool: Stay informed about security patches and updates for Continuous-Claude-v3. Given its early stage (very few users, limited production history), monitor security advisories closely and plan to upgrade promptly.

Red flags to watch for

• Unexplained data in ledgers: If API keys, passwords, or customer information appear in logs or stored state after an agent run, stop using the tool immediately and investigate how they got there.
• Over-permissioned handoffs: If you notice agents requesting or receiving more data than their job requires—especially credentials or system-wide access—treat it as a sign of possible prompt injection or misconfiguration.
• Silent or missing audit logs: If you cannot retrieve a complete record of what an agent accessed, sent, or stored, you've lost visibility into potential breaches.
• Inconsistent isolation: If the same sensitive data appears across different agent runs that should be isolated, the "context windows" may not actually be separate, creating cross-contam
