Trust the Model, Audit the Binary
A coding agent's client is the most privileged binary on your machine. Claude Code's hidden prompt fingerprint shows why you audit it, not trust it.
AWS Monthly (June '26): Agents Get a Feedback Loop
June 2026 on AWS: the Summit in New York turned production traces into agent improvement, shipped Continuum for security, and took the AgentCore harness to GA.
Agents on Call, Part 5. The Team: Supervisor and Three Specialists
A supervisor delegates to triage, runbook, and cost agents over the network, AgentCore Memory ties their findings together, and when one agent still wins.
AWS Built a Sandbox for AI-Generated Code: Lambda MicroVMs
AWS Lambda MicroVMs give AI agents a place to run model-generated code, isolated at the VM level. The missing piece for production agents was the runtime.
Your Multi-Agent System's Real Limit Is Tokens Per Minute
Amazon Bedrock now exposes per-model tokens-per-minute quotas in Service Quotas. For agents, TPM is the real scaling ceiling. Plan for it before the 429s start.
Estonia Is Giving AI Agents an ID. That Is the Easy Part
Estonia plans to issue AI ID codes to AI agents, a world first. The identity is the easy part: authority, delegation, and accountability are the real work.

There is no AI model called Le Chaton Fat. No weights, no API, no benchmark. Here is how a Mistral cat joke became the AI community's favourite running gag.
Agents on Call, Part 4. Tools and the Gateway: MCP, Allowlists, Read-Only Default
Tools move behind AgentCore Gateway: scoped Lambdas, cross-account read-only roles, and the one gated path that is allowed to change anything.
AI Coding Agents Need Staging Environments Too
Teams gave coding agents production credentials and called it velocity. An agent is a contributor with no judgment, and it needs the same environment ladder.
Agents on Call, Part 3. First Agent: Incident Triage in Strands
The first agent ships: a Strands triage agent on AgentCore Runtime, its evidence-first system prompt, two read-only tools, and the Terraform that deploys it.
