Anthropic Engineer Proposes 'Loop Engineering'
blaizedsouza · x · 2026-07-18
A senior Anthropic engineer shares the concept of 'Loop Engineering' for building agentic systems, advocating for building systems that prompt themselves instead of manual prompting.
The system operates on a Plan → Discover → Build → Verify → Repeat loop, with five key steps per cycle:
- Discover: Autonomously finding work (like failed CI, unresolved issues) rather than passively receiving tasks.
- Handoff: Assigning a dedicated git worktree to each task to avoid parallel agent conflicts.
- Verify: Introducing a second agent to act as an 'adversary', reviewing the code with the assumption that it has flaws.
- Persistence: Writing results to disk to prevent loss during context refreshes.
- Scheduling: Using cron jobs to wake up the agent and close the loop.
The core insight is that agents often 'grade their own homework' during self-evaluation, making external verification mechanisms essential.
