+*Repository Ability Registry Requirements*
+
+# **Product Requirements Document (PRD)**
+
+## **Repository Ability Registry (v0.1)**
+
+---
+
+# 1. **Purpose**
+
+The **Repository Ability Registry** provides a structured, inspectable orientation layer for code repositories by mapping them from **abilities → capabilities → features → implementation → evidence**.
+
+It enables developers, architects, and agents to:
+
+* understand what a repository is useful for
+* inspect how it implements that usefulness
+* compare repositories based on real functionality
+* search repositories using natural language
+
+---
+
+# 2. **Problem Statement**
+
+Modern code repositories suffer from **orientation opacity**:
+
+* usefulness is unclear from structure alone
+* README files are incomplete or misleading
+* functionality is scattered across code
+* reuse decisions rely on tribal knowledge
+
+This results in:
+
+* wasted time exploring repositories
+* duplicated work
+* poor architectural decisions
+* low reuse of existing assets
+
+---
+
+# 3. **Goals**
+
+## 3.1 Primary Goal
+
+> Enable users to **register a repository and understand its usefulness within minutes** via an inspectable ability map.
+
+---
+
+## 3.2 Secondary Goals
+
+* enable **natural language search** across repositories
+* provide **traceability from abstraction to code**
+* establish a **foundation for proof-of-ability integration**
+* support both **human and agent interaction**
+
+---
+
+## 3.3 Non-Goals (v0.1)
+
+* full automated benchmarking
+* advanced ontology enforcement
+* marketplace features
+* monetization features
+* full CI/CD integration
+
+---
+
+# 4. **Users**
+
+## 4.1 Developer / Architect
+
+* needs to find reusable functionality
+* needs to understand unfamiliar repos quickly
+
+## 4.2 Repository Owner
+
+* wants their repo to be understandable and discoverable
+
+## 4.3 Registry Curator
+
+* ensures quality and correctness of extracted data
+
+## 4.4 Agent / Automation
+
+* queries registry programmatically
+
+---
+
+# 5. **Core Concepts**
+
+```text
+Ability     = why the repository is useful
+Capability  = what behavior it provides
+Feature     = how the behavior is exposed/implemented
+Evidence    = why the capability can be trusted
+```
+
+---

+
+---
+
+# 12. **Risks**
+
+---
+
+## 12.1 Extraction Quality Risk
+
+* automated inference may be inaccurate
+
+**Mitigation:** human review required
+
+---
+
+## 12.2 Over-Complexity Risk
+
+* ontology becomes too heavy
+
+**Mitigation:** keep schema minimal in v0.1
+
+---
+
+## 12.3 Adoption Risk
+
+* users may not contribute metadata
+
+**Mitigation:** provide value via auto-analysis first
+
+---
+
+# 13. **Future Extensions**
+
+* integration with CI/CD for live updates
+* ability benchmarking integration (ties back to GIL)
+* capability maturity scoring
+* dependency graph across repositories
+* marketplace / discovery layer
+* automated code reasoning agents
+
+---
+
+# 14. **Positioning**
+
+> The Repository Ability Registry is the missing orientation layer between raw code and practical reuse—making repositories understandable, comparable, and actionable.
