Core Features & Use Cases

  • Per-persona drift scoring and drifted-attribute identification
  • Cross-backlog and feature signals fusion to surface misalignments
  • Actionable recommendations to update VPC attributes

Quick Start

Run /specrails:vpc-drift to generate a drift report for your project.

FAQPage Schema
How do I detect user persona drift in my product backlog?▼

User persona drift is detected by analyzing backlog signals, implemented features, and agent-memory patterns to surface alignment gaps between documented VPC attributes and actual delivery. This produces per-persona drift scores and concrete recommendations.

What is VPC persona drift and how is it measured?▼

VPC persona drift is the misalignment between defined user personas and actual usage patterns. It is measured by fusing cross-backlog and feature signals to generate per-persona drift scores, identify drifted attributes, and output structured JSON or Markdown reports.

How do I fix persona alignment gaps in my VPC?▼

To fix persona alignment gaps, the analysis generates actionable VPC update recommendations across multiple phases based on detected drifted attributes. It uses keyword-based matching and semantic assessment to provide clear drift levels and misalignment indicators.

Can I export VPC drift reports in structured formats like JSON or Markdown?▼

Yes, VPC drift reports can be exported in structured JSON or Markdown formats. The system outputs per-persona drift scores, drifted attributes, and concrete VPC update recommendations with clear drift levels and misalignment indicators for downstream use.

Does VPC drift detection require external dependencies or components?▼

VPC drift detection operates without external dependencies or components, relying on internal analysis of backlog signals, implemented features, and agent-memory patterns to evaluate alignment gaps and generate per-persona drift scores.

When should I run a VPC drift report for my project?▼

You should run a VPC drift report when documented user personas potentially diverge from actual delivery. The analysis identifies drifted attributes and alignment gaps using semantic assessment and cross-backlog signal fusion to recommend VPC updates.
