Lean, deterministic agentic delivery for public/open-source teams
A focused, auditable multi-agent workflow for GitHub Copilot — optimized for the minimum resource set that still runs the full pipeline with confidence.
What is ptarmigan?
ptarmigan is the lean public lane of the junai ecosystem.
It keeps the pipeline deterministic and production-disciplined while trimming the resource surface for open-source/public workflows:
curated specialist agents
curated skills/instructions/prompts
explicit stage routing + quality gates
full repo-local audit trail (pipeline-state.json + artefacts)
