Midjourney Prompt Learning System

A skill that knows Midjourney. The foundation is a structured understanding of Midjourney V7 built from the official documentation — every parameter, prompt syntax rule, reference system, and style code mechanic. On top of that, a learning loop: each session extracts patterns from what worked and what didn't, building a knowledge base of craft that improves first-attempt quality over time.

Architecture

You are a multimodal reasoning model. You don't need pipelines — you ARE the visual critic, gap analyzer, and prompt rewriter. You analyze MJ output images directly, score dimensions, identify gaps, and rewrite prompts.

The one thing you can't do natively is remember across sessions. That's what the persistent layer provides — the database, patterns, and evidence tracking.

Knowledge Foundation (ships with the skill)

File What It Contains Source
knowledge/v7-parameters.md Every V7 parameter, prompt structure rules, breaking changes from V6 Official docs
knowledge/translation-tables.md Visual quality → prompt keyword mappings (lighting, mood, material, color, composition) Official docs + tested refinements
knowledge/official-docs.md Documentation map linking each MJ feature to its official page URL docs.midjourney.com
knowledge/failure-modes.md Diagnostic framework for common MJ failure patterns Session-learned, evidence-backed
knowledge/learned-patterns.md Auto-generated pattern summaries (grows through use) Extracted from sessions
knowledge/keyword-effectiveness.md Keyword effectiveness rankings (grows through use) Extracted from sessions

The static files (v7-parameters, translation-tables, official-docs) are the skill's baseline knowledge — what a skilled MJ user would know from reading the documentation carefully. The dynamic files (failure-modes, learned-patterns, keyword-effectiveness) are populated through real sessions and grow over time.

Module Dependencies

Module Purpose Required MCP
Core rules (core-*) Reference analysis, prompt construction, scoring, iteration None
Learning rules (learn-*) Pattern lifecycle, reflection, keyword tracking sqlite-simple
Automation rules (auto-*) Browser automation for midjourney.com playwright

Core only (manual): Load core-* rules. Copy prompts to MJ manually. Core + Learning: Add learn-* rules + sqlite MCP. Patterns persist across sessions. Full system: Add auto-* rules + playwright MCP. Hands-free iteration.

# SQLite (for learning rules)
claude mcp add sqlite-simple -- npx @anthropic-ai/sqlite-simple-mcp mydatabase.db

# Playwright (for automation rules)
claude mcp add playwright -- npx @playwright/mcp@latest --headed

# Initialize the database
sqlite3 mydatabase.db < schema.sql

Rules Quick Reference

Rule What It Covers
core-reference-analysis 7-element visual framework, vocabulary translation
core-prompt-construction V7 prompt structure, keyword practices, knowledge application
core-research-phase Coverage assessment, community research workflow
core-assessment-scoring 7-dimension scoring, confidence flags, agent limitations
core-iteration-framework Gap analysis, action decisions, aspect-first approach
learn-data-model Database schema, session structure, ID generation
learn-pattern-lifecycle Confidence graduation, decay, knowledge generation
learn-reflection Session lifecycle, automatic reflection, contrastive analysis
auto-core-workflows Prompt submission, smart polling, batch capture, animation
auto-reference-patterns Selector strategy, error handling, image analysis

Scoring

All iterations scored on 7 dimensions: subject, lighting, color, mood, composition, material, spatial. All 7 always scored (1.0 for "not applicable"). Scores are preliminary until user-validated. See rules/core-assessment-scoring.md.

Commands

Command Purpose
/new-session Start a session with full knowledge application
/log-iteration Log a generation attempt with scoring and gap analysis
/reflect Cross-session pattern analysis and knowledge extraction
/research [focus] Research community techniques for a challenge
/show-knowledge [category] Display learned patterns
/apply-knowledge <desc> Pattern-informed prompt for a description
/discover-styles Browse and catalog MJ style codes
/validate-pattern [id] Mark pattern as validated or contradicted
/forget-pattern [id] Deactivate a pattern

Key Principle

Every pattern must have logged evidence. The system learns from real iteration data, not assumptions. Confidence levels (low/medium/high) reflect how many times a pattern has been tested and its success rate.
