Compare
Sorry, something went wrong.
No results found
Highlights
Adds opt-in Codex and Claude Code specialist model-routing overlays while keeping core-only installation as the default.
Preserves the user's root-session model; explorer and implementer use lower-cost models, while reviewer and architect use higher-capability models.
Renames the Companion Skill from ai-collaboration-workflow to repo-continuity.
Pins the Companion Skill bootstrap and Quick Start to v4.2.0.
Compatibility
Existing initialized repositories do not need to be initialized again.
Users upgrading the global Companion Skill should remove ai-collaboration-workflow, install repo-continuity, and invoke $repo-continuity.
Model routing remains disabled unless explicitly requested.
The Doctor and initialization cleanup still recognize the legacy payload marker for interrupted setups.
This release does not use GPT-5.3-Codex-Spark.
Validation
Full distribution lifecycle validation passes.
The official skills CLI installs repo-continuity from the public v4.2.0 tag.
The installed Skill bootstraps 22 core files from the pinned tag with no model-routing adapter by default.
Public opt-in Codex routing installs the expected .codex configuration and all four specialist agents.
