name: memory-write description: Persist a decision or learning to Mother-Harness long-term memory

Memory Write Skill

Saves decisions, rationale, and learnings to persistent memory for later retrieval.

When to Use

Use this skill when you want to:

• Record an important design decision
• Save a learning or insight from a project
• Store rationale that should be retrievable later
• Document an architectural choice

Input Format

Provide structured information:

CopyDecision: [The decision that was made]
Rationale: [Why this decision was made]
Project: [Project name - optional]
Tags: [Comma-separated tags - optional]

Example

CopyDecision: Use PostgreSQL over MongoDB for the user service
Rationale: Need strong consistency for financial transactions, relational queries are primary use case, team has more SQL expertise
Project: payment-platform
Tags: database, architecture, infrastructure

What Happens

1. The decision is sent to the n8n memory-write webhook
2. An embedding is generated for semantic search
3. The record is stored in both Qdrant (vector) and Postgres (relational)
4. You receive a confirmation with the record ID

Implementation

Call the n8n webhook at: http://localhost:5678/webhook/memory-write

Copycurl -X POST http://localhost:5678/webhook/memory-write \
  -H "Content-Type: application/json" \
  -d '{
    "decision": "Use PostgreSQL over MongoDB",
    "rationale": "Strong consistency needed...",
    "project": "payment-platform",
    "tags": ["database", "architecture"]
  }'
