AdvSim2Real : Training Web Agents Against Adaptive Prompt Injection in a Web World Model
Introduces AdvSim2Real, a training framework for web agents that defends against adaptive prompt injection by simulating attacks in a web world model.
Kiro — Workflows, Safer Untrusted Workspaces, and Enterprise Sign-In Controls
Claude Sonnet 5.5 is now available with experimental support across the Kiro IDE, CLI, Crew, and Web for Pro, Pro+, Pro Max, and Power customers in us-east-1 (IAD) and eu-central-1 (FRA); the Oct 2, 2026 changelog update also ships Workflows, safer untrusted workspaces, and enterprise sign-in controls.
Devin: October 5, 2026
Session workspace gets a Terminal tab for running commands on Devin's machine — the Files tab can now be opened while Devin is asleep, and opening Files or Terminal wakes Devin. Also in this cut: a ⌘K command palette, Devin Review effort levels, and Slack user-group mentions rendering as named @group mentions in the webapp.
OmniSeek: Native Tool Integration for Multi-turn Audio-Visual Reasoning
Adobe paper on native tool integration for multi-turn audio-visual reasoning; the page notes code, weights, and data are under Adobe's internal review.
4 new model(s) priced in the LiteLLM registry
Four new models added to LiteLLM's pricing and context registry: chatgpt/gpt-6-astra, chatgpt/gpt-6-luna, chatgpt/gpt-6-sol, and chatgpt/gpt-6.1-sol.
Devin: October 2, 2026
Oct 2 notes: sidebar search now surfaces matching sub-sessions and workflow sessions under collapsed parents, and the session status stops prompting to review/approve/merge a PR once that step is done. Long-session fixes cover transcript flicker/blanking on background-tab return and self-scrolling while reading older history.
Claude platform release notes — October 1, 2026
Models API adds a `line` field: `GET /v1/models` and `GET /v1/models/{model_id}` now return the model line (Opus 4.5 and 4.6 both report `opus`; null for a model in no line). Same page: Claude Sonnet 4.5 (`claude-sonnet-4-5-20250929`) is deprecated, retirement on the Claude API scheduled for November 30, 2026 — migrate to Claude Sonnet 5.5.

Warp's post on defining its software factory in code, Terraform-style — the pattern behind Warp Factories, which run fleets of coding agents across the SDLC (first-pass review on every PR, bug reproduction and routing).
Getting the most out of Opus 5.5 in Claude and Claude Code
claude.dev post on getting the most out of Opus 5.5 in Claude and Claude Code — 238 points and 157 comments on HN; a commenter describes giving Opus general directives to speed up CI while caring about billing minutes.
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.
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 ` .devinenterprise.com` instead of `app.devin.ai` — re-run `/
EVOKE: Eliciting World Knowledge in Agents for Transferable Decision-Making
HF Daily Papers selection on eliciting world knowledge in agents for transferable decision-making.

Uses tool-augmented reinforcement learning to bridge causal transitions for video event prediction.
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.
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.
1jehuang
1Jehuang/Jcode 0.90.1
OpenAI-compatible providers that answer 529 or another 5xx "heavy usage" error are now retried automatically instead of failing the turn, and /usage shows real quota windows for Kimi Code, Cursor, and the Z.ai Coding Plan.
can1357
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.
earendil-works
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`.
NousResearch
Pinned inputs 8
Hermes Agent release 'Pinned inputs 8' — no release notes in the feed; the tag is the only source.
ordewell
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.
RunMaestro
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.
socai-io
Socai-Io/Socai 0.6.4
Adds per-platform browser pacing, cloud session workers, and click-first deep reads on X; telemetry errors now redact provider API key values.
the-open-engine
The-Open-Engine/Zeroshot 10.10.1
Preserves the invoking shell's USER in local Claude processes so macOS Keychain login works without a wrapper; hosted processes still ignore native context.
vercel-labs
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.
