SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Overnight reflexion collects build evidence and regenerates an improved PRD (prd.json) to capture lessons from overnight autonomous coding runs, enabling cleaner rebuilds and faster iteration.

Core Features & Use Cases

  • Multi-judge critique and knowledge extraction over the full evidence trail (post-build-findings.json, observer notes, regression data) to refine PRD.
  • Generates an updated prd.json with e2e-derived criteria, expert hints, and observer-guided improvements for the next cycle.
  • Stores updated assets (CONSTITUTION.md, CLAUDE.md, AGENTS.md) and a reflexion report for audit and reuse.

Quick Start

Trigger the nightshift reflexion to generate an updated PRD from post-build findings.

FAQPage Schema
How do I refine a PRD using post-build findings from autonomous coding runs?

Post-build reflexion analyzes post-build findings to regenerate a refined PRD. It extracts lessons learned from overnight autonomous coding runs to drive concrete improvements and guardrails for the next cycle.

What is overnight reflexion and how does it improve autonomous coding cycles?

Overnight reflexion is a quality-loop process that collects build evidence and regenerates an improved prd.json. This enables cleaner rebuilds and faster iteration by capturing lessons from the previous run.

How do I trigger nightshift reflexion to generate an updated PRD?

You trigger the nightshift reflexion to generate an updated PRD from post-build findings. The process outputs a structured, machine-parsable payload that informs PDR generation and future skill guidance.

Does post-build reflexion work with Firebase robo data and e2e test results?

Yes, post-build reflexion focuses on content gate, e2e results, and Firebase robo data. It uses these inputs along with observer interventions to refine the PRD with e2e-derived criteria.

What assets are updated when analyzing post-build findings for lessons learned?

Analyzing post-build findings stores updated assets including CONSTITUTION.md, CLAUDE.md, and AGENTS.md. It also generates a reflexion report for audit and reuse alongside the refined prd.json.
