Summary

0.10.0 adds four Harnesses alongside Claude Code and Codex: Antigravity CLI (agy), Grok Build (grok), Muse Code (muse) and OpenCode (opencode). Each can be selected on the command line, in User config and in Setup (#442). It also makes interruption stop Harness, Git and GitHub work while letting finishing work complete.

• Four new Harnesses, each behind its own Harness adapter (Gather Claude and Codex into Harness adapters #441). Every adapter runs sessions and Resumes unattended, checks Model and Effort before any work, loads the Factory skills, reports progress, final reply and usage, and stops the whole process tree on interruption.
  • harness agy, with [harness.agy] (Add the agy Harness (Antigravity CLI) #445).
  • harness muse, with [harness.muse]; Setup proposes muse-spark-1.3 (Add Muse Code Harness #444).
  • harness grok; invalid Models and Efforts fail before a Claim, worktree or Command log is created (Add the Grok Build Harness #446).
  • harness opencode, with [harness.opencode] (Add the OpenCode Harness #447).
• Setup lists only installed Harnesses (Add the agy Harness (Antigravity CLI) #445, Add Muse Code Harness #444, Add the Grok Build Harness #446).
• A failed Harness turn now fails the Run even when the CLI exits zero. The PR stays draft and no Resume starts (Deepen completed Harness session interpretation #458).
• Interrupting a Command stops each session's whole process tree on every Harness. This includes commands that started their own process group or session, and commands started during the stop grace period (Stop every Harness session process tree on interruption #443). Sessions stay interruptible after the CLI exits (Unify Harness process lifetimes and preserve interruption #449).
• Model/Effort checks and Setup are interruptible. Cancelling terminal Setup exits 1 with interrupted, restores terminal attributes, and leaves User config and Credentials unchanged (Own all Model/Effort checks and make Setup interruptible #453).
• Ordinary Git and GitHub work stops when its Command is interrupted. Failed run salvage, confirmed Self-merge cleanup, Claim ending, worktree cleanup and Spec Ticket accounting still finish (Spec: Deepen Command execution for Git and GitHub #470, Share Command execution ownership for capture and streaming #469, Make Git execution interruptible with completion views #471, Make GitHub execution interruptible and preserve finishing workflows #472). An interrupted merge is accepted only when GitHub reports MERGED at the requested head. Waiting for a repository lock also stops on interruption (Honor Command interruption during repository lock acquisition #474).
• Failed Harness sessions keep recoverable usage and warnings while reporting the original transport error (Retain Harness interpretation after transport failures #462).
• Malformed Harness stderr no longer hides a child Run's actual ending (Own child Run execution for Spec runs and Base fixes #464).
• Concurrent Ticket Runs stay owned through teardown, with child salvage finished before Spec worktree cleanup (Own concurrent child Runs through collective teardown #476).
• Internal reworks of Setup's User config editing (Prepare User config documents behind one validated interface #451), Setup's Harness settings (Deepen Harness settings behind one Setup interaction #456), and Claude and Grok stream interpretation (Deepen Claude and Grok Harness stream interpretation #460).

Also: docs and research updates (#426, #430).
