Coding agents

Stories

• Building a C compiler with a team of parallel Claudes (Anthropic Engineering)

  Anthropic engineering post · Story page

  Sixteen parallel agents built a Rust C compiler able to compile the Linux kernel, with little active supervision.

• Intervention Rates Are the New Build Times (Continue)

  Continue blog · Story page

  A proposal to track how often a human has to step in, the way teams once tracked build times.

• Letta Code: A Memory-First Coding Agent (Letta)

  Letta blog · Story page

  A model-agnostic coding agent that researches a codebase to form memories and can rewrite its own system prompt.

• Six parallel agent threads that survive closing the laptop (Theo)

  X post · Story page

  Six agent threads running in parallel over plane wifi, still working after the laptop shuts, and picked back up on a phone. Coding-agent sessions are drifting toward remote and persistent by default.

• EA-Graph: Artifact-Anchored Verification Memory for Coding Agents under Upstream Drift (arXiv)

  arXiv preprint · Story page

  EA-Graph anchors a coding agent's verification memory to the exact artifacts that supported each claim, and tracks evidence strength separately from freshness. When upstream code drifts or disappears, old claims get classified as affected or unprovable instead of quietly surviving as stale prose notes.

• How we built Claude Code auto mode: a safer way to skip permissions (Anthropic Engineering)

  Anthropic engineering post · Story page

  Auto mode uses classifiers to approve some commands and file changes automatically, aiming for a middle ground between prompting on everything and turning permissions off. The design is informed by incidents where agents deleted branches, exposed credentials, or attempted production migrations.

• Meta's Muse Code Tackles 24-Hour Coding Jobs Where Other AI Agents Quit (AlphaSignal)

  newsletter item · via @AIatMeta · Story page

  Meta launched Muse Code, a terminal coding agent built around persistent sub-agents and a co-trained model, aimed at jobs that run for 24 hours. Long-horizon autonomy is where today's harnesses fall apart, so this is the regime worth watching.

• Devin Outposts run on Vercel Sandbox microVMs (Cognition)

  X post · Story page

  Devin can now run inside isolated Vercel Sandbox microVMs, with Docker support, VPN access to private networks, and resume-from-snapshot that restores the repo, dependencies, and build state.
