Memory Bank Protocol

1. The Core Rule

"Read First, Write Last."

  • Start of Task: You MUST read MEMORY.md (at project root) to understand the project's current state, constraints, and architecture.
  • End of Task: You MUST update MEMORY.md if you have:
    • Added a new feature.
    • Changed the architecture.
    • Discovered a new bug or constraint.

2. File Structure Constraint

Your MEMORY.md updates must roughly follow this template to maintain readability:

## 1. Active Context

- **Goal**: [Current Objective]
- **Status**: [Progress]

## 2. Architecture & Tech Stack

- [Key tech decisions]

## 3. Known Issues & Technical Debt

- [List of things that are broken or hacky]

## 4. Operational Rules

- [Do's and Don'ts specific to this project]

3. Maintenance Triggers

  • New Pattern: If you implement a new pattern (e.g., "All lists must be virtualized"), add it to Operational Rules.
  • Bug Hunt: If you spend >10 mins debugging something, write the "Cause & Fix" in Known Issues so the next agent doesn't suffer.
  • Schema Change: If api/ changes, update Architecture.

4. Verification Checklist

  • Did I read MEMORY.md at the start?
  • Did I verify if my plan conflicts with "Known Issues"?
  • Did I update "Active Context" to reflect my completed work?
