Claude Managed Agents: Decoupling Brain, Hands, and Session
Aug 1
Anthropic's Managed Agents service virtualizes agent components—session (event log), harness (the Claude loop), and sandbox (execution environment)—into separate interfaces that can be independently swapped or replaced, similar to how OS abstractions like process and file decoupled software from hardware. This solves a 'pet vs. cattle' infrastructure problem where coupling everything into one container made sessions fragile and undebuggable, and baked in assumptions (like requiring code to live in the same container) that broke when customers needed different infrastructure setups.

Two-Agent Pattern for Long-Running Coding Agents
Aug 1
Long-running AI agents lose all memory between context window sessions, causing them to either attempt too much at once and fail mid-implementation, or falsely declare a project complete. The solution is a two-part system: an initializer agent that sets up project scaffolding (init script, progress log, initial commit), followed by coding agents that make incremental progress each session while leaving clean, documented state for the next session.

Loops are Replacing Prompts. Verification is About to Be Your Biggest Problem.
Arjun Iyer · Jun 21
Three eras of AI coding — prompt-driven, spec-driven, loop-driven — and why verification becomes the binding constraint as the human moves up a level each era. Loop economics: total cost = iterations-to-verified × cost-per-iteration.

How Coding Agents Work with LLMs
Simon Willison · Jun 7
Coding agents are software harnesses that extend LLMs with additional capabilities through invisible prompts and callable tools. LLMs work by completing text sequences using tokens (not words), with providers charging based on token usage. Chat templated prompts simulate conversations but require replaying entire conversation history each time, making longer conversations more expensive.
