📦 Devin September 30, 2026 — Devin fixes message loss on connection drops — messages sent right before a disconnect are now saved server-side. Also read-only shell preview and session preview cards.

📦 Copilot Selected models in GitHub deprecated — GitHub Copilot deprecates selected models across all experiences as of Oct 2 — check if your team's pinned models are affected and migrate.

Reliability and deprecation day: Devin patches a message-loss bug, while Copilot forces model migrations — check your pinned models before they break.

📚 OSWorld-Science: A Benchmark of Computer Use Agents for Learning and Using Scientific Software — Extends OSWorld to scientific software — tests whether computer-use agents can learn and operate domain tools, not just navigate generic UIs. Scientific software presents a demanding test.

Benchmarks are moving from generic UI navigation to domain-specific software — expect agent evals to get harder and more specialized.

💬 Show HN: Pi pod – Run your pi coding agent in sandboxes on your own server — Pi pod runs the Pi coding agent in isolated sandboxes ("pods") on your own server, with composable environments — a self-hosted path for teams moving agent workloads off SaaS.

Self-hosted agent sandboxing is becoming productized; if you're not ready to hand agent workloads to a SaaS, this is the pattern to watch.

📦 Copilot code review: API support and new default effort level — Copilot code review is now callable via API, and Balanced becomes the default effort level — teams can trigger reviews in CI without the UI.

📦 Factory 0.233.0 — Factory 0.233.0 — resume a session with a message, script output trimming keeps start/end, cut-off replies retry. Fixes oversized requests and malformed tool args.

Today's harness moves are about session continuity and context-window handling: resume-with-message and oversized-request fixes in Factory, API-driven review in Copilot. Operators should test these paths before relying on them.

📚 BaRe-Mem: Bayesian Reliability Memory for Robust and Adaptive Agent Consultation — Online Bayesian reliability memory that learns which agents to trust for consultation, adapting as reliability shifts. Useful for multi-agent routing where trust calibration matters.

📚 Show HN: Corral – Kill every command your agent starts — Kills orphaned processes agents leave behind — tail -f, background jobs — after the agent exits. Solves a real operational headache for anyone running agents that spawn subprocesses.

Process hygiene and trust calibration are the unglamorous edges of agent operations — today's items address both.

💬 Inside Anthropic's quest to instill morality into its models — 357-comment HN debate — NYT details Anthropic bringing religious scholars in to help encode values into Claude; the 144-point HN thread skews hard skeptical ('bubble-phase research'), but this values-tuning is the layer that decides how Claude agents behave on ambiguous requests.

💬 PPSSPP forks multiplying 'given the turn toward Claude Code' — Retro-emulation dev flags the new PPSSPP forks (tico-ppsspp, ppsspp-wasm) and predicts more 'given the turn toward Claude Code' — agent harnesses making a complex C++ emulator maintainable by small teams. Thin engagement, but it's the agents-reshape-OSS-maintenance thesis in the wild.

The values Anthropic bakes into Claude decide how your agents handle ambiguous requests, and Claude Code is quietly making 'fork it and maintain it yourself' viable for big codebases — two capability shifts hiding in culture-war clothing.

📚 EngiWorld: What Can Frontier Agents Deliver in Professional Engineering Environments? — EngiWorld bills itself as the first benchmark covering the complete professional engineering workflow — not isolated coding tasks. Useful for calibrating what frontier agents actually deliver on multi-step engineering work.

📚 OMP 18.6.1 — Subagent follow-up messages now arrive as background jobs you can wait on or cancel (delivered once); fixes OpenAI context compaction wrongly rejecting sessions with many screenshots, and preserves DeepSeek-family reasoning context for warm Responses sessions.

📚 Ordewell 0.6.3 — Closes the planner confinement hole from 0.6.2 — a `cd` chain no longer lets the research agent read outside the workspace unprompted. Terminal transport now runs OpenCode 2.x and works on macOS without tmux.

Two runtime fixes are the actionable part today — Ordewell closed a workspace-confinement escape and OMP made subagent replies waitable background jobs — while the benchmark paper suggests frontier agents still don't clear end-to-end engineering work.

📦 Pi 1.0.0 — The TUI runs fullscreen by default (`tuiMode: "regular"` keeps the terminal's normal scrollback); codemode uses about 40% fewer prompt tokens and its errors tell the model how to recover; MCP OAuth hardening adds `oauth.authServerMetadataUrl`, RFC 9207 `iss` checks, credentials per server, and step-up sign-in that keeps granted scopes. Also in 1.0.0: `models.generateImages()` in codemode using the session's credentials, and Radius sign-in plus its MCP server setup in one step from `/login`.

📦 Anthropic: Claude Frontier Academy — $100M to train 10,000 engineers — Anthropic commits $100M to train 10,000 Frontier Deployed Engineers and tackle the enterprise AI talent gap — trained to "the same standard of skills as Anthropic's own engineers," with first cohorts from Accenture, Bain, and Capgemini.

Pi's release notes pair the codemode token cut — about 40% fewer — with errors that tell the model how to recover.

📚 Runmaestro/Maestro 0.17.8 — Security release: the built-in server that maestro-cli and the phone interface drive listened on the whole network from the moment Maestro opened, even with Live off, and answered requests from any web page — anyone with its URL could run commands. It now listens on 127.0.0.1 only until Live is turned on.

📚 fx 0.0.13 — Ultrafast lands on supported OpenAI models through AI Gateway (a higher-priced inference tier) — launches up to 23× faster, shell calls up to 8.6× faster, exits up to 44× faster in matched benchmarks; subagents and ACP sessions support it. Breaking: terminals launched through the shell tool now stop when fx exits, and new libfx checkpoints cannot be restored by older versions.

📚 Show HN: Offrun – manage every coding agent from one workspace — Run Claude Code, Codex, AGY, and Grok Build side by side — see who is working, who needs you, and what every account has left. 76 points and 64 comments on HN.

📚 EVOKE: Eliciting World Knowledge in Agents for Transferable Decision-Making — HF Daily Papers selection on eliciting world knowledge in agents for transferable decision-making.

📦 Devin CLI v3000.11.1 / v3000.11.3 — v3000.11.1 adds `devin --cloud` / `/cloud` to run Devin Cloud sessions from the CLI, `/handoff` and `/pickup` to bring a cloud session's PR branch into a local session, and `devin ssh` / `/ssh` to connect to a Devin Cloud VM; ACP clients can now select Devin models, thinking effort, and speed. Agent events and metrics export to an OpenTelemetry collector via the `otel` config block or `OTEL_EXPORTER_OTLP_*` variables. v3000.11.3 fixes browser login to record the signed-in tenant's webapp host so `/handoff` and `/share` links open on `<customer>.devinenterprise.com` instead of `app.devin.ai` — re-run `/login` to pick it up.

📦 xAI API release notes — October — xAI API release notes page updated for October; the docs list Grok 4.7 under Latest Models and include a Multi Agent section.

The Devin CLI changelog lists v3000.11.1 (September 21, 2026) and v3000.11.3 (September 22, 2026); the v3000.11.3 browser-login fix requires re-running `/login` to take effect.
