AI Context Generator

A reusable skill for creating project knowledge bases that help coding agents work faster and smarter.

🎯 When to Use This Skill

Activate when:

• Setting up a new project for AI-assisted development
• User requests: "create ai-context", "setup project knowledge", "generate .ai-context"
• Existing .ai-context is outdated and needs regeneration
• After major project restructuring

Do NOT activate when:

• Project already has fresh .ai-context (check SKILL.md date)
• User asks for unrelated documentation
• Simple code tasks with clear existing context

📋 What This Skill Generates

Creates a .ai-context/ directory with:

.ai-context/
├── SKILL.md                    # Entry point with activation rules
├── DYNAMICS.md                 # Active issues & constraints (Dynamic)
├── references/
│   ├── PROJECT-ESSENCE.md      # What & why (High stability)
│   ├── ARCHITECTURE.md         # Component relationships (Medium stability)
│   └── DECISIONS.md            # Design decisions (Update on change)
└── meta/
    ├── MAINTENANCE.md          # How to maintain this knowledge
    ├── templates/              # (Optional) Custom templates
    └── scripts/                # (Optional) Maintenance scripts

🔧 Generation Process

Step 1: Gather Project Intelligence

Before generating, collect:

□ Read AGENTS.md (if exists) — operational rules
□ Read README.md — user-facing description
□ Read package.json — dependencies, scripts, entry points
□ Scan directory structure — identify components
□ Read docs/ or litho.docs/ — existing documentation
□ Identify key source files — main entry points
□ Note technology stack — frameworks, languages, platforms

Step 2: Extract Knowledge

For PROJECT-ESSENCE.md:

• What is this project? (one sentence)
• Why does it exist? (problem/solution)
• Who is it for? (target users)
• What does it provide? (key features)
• Core constraints? (security, compatibility)

For ARCHITECTURE.md:

• System diagram (ASCII or Mermaid)
• Component responsibilities
• Data flow between components
• Key dependencies
• Important patterns

For DECISIONS.md:

• Non-obvious design choices
• Trade-offs made
• Constraints accepted
• Decisions that might be revisited

For DYNAMICS.md:

• Current blockers
• Known workarounds
• Temporary constraints
• Recently resolved issues (brief)

Step 3: Generate Files

Use templates from templates/ directory:

1. Start with SKILL.md — entry point with activation rules
2. Generate references/PROJECT-ESSENCE.md — core identity
3. Generate references/ARCHITECTURE.md — component map
4. Generate references/DECISIONS.md — design rationale
5. Generate DYNAMICS.md — active issues
6. Generate meta/MAINTENANCE.md — upkeep guide

Step 4: Validate Quality

□ SKILL.md has clear activation triggers
□ PROJECT-ESSENCE.md readable in 2 minutes
□ ARCHITECTURE.md shows big picture (no code)
□ DECISIONS.md justified with rationale
□ DYNAMICS.md only contains current issues
□ All files dated at top
□ Total token budget < 4000 tokens

📝 Writing Principles

Do:

• ✅ Write for someone who knows nothing about the project
• ✅ Use diagrams over paragraphs
• ✅ Focus on "why" not "how"
• ✅ Keep files under 150 lines each
• ✅ Link between related sections
• ✅ Include "Last updated" dates

Don't:

• ❌ Copy-paste code snippets (link to files instead)
• ❌ Document every file/function
• ❌ Include details that change frequently
• ❌ Duplicate content across files
• ❌ Use jargon without context

🔄 Integration with AGENTS.md

AGENTS.md = "How to work" (commands, style, rules)
.ai-context = "What the project is" (architecture, decisions, issues)

Both should be read at session start. They serve different purposes and should not overlap.

📚 Template Reference

Templates are provided in templates/:

🛠️ Automation Scripts

Scripts in scripts/ can help with:

💡 Example Usage

User: "Setup ai-context for my project"

Agent:

1. Activate this skill
2. Read AGENTS.md, README.md, package.json
3. Scan directory structure
4. Generate each file using templates
5. Ask clarifying questions if needed:

- "What's the main problem this project solves?" - "Any non-obvious design decisions I should know about?" - "Current blockers or workarounds?"

⚠️ Important Notes

• Generated knowledge is a starting point, not final truth
• Agent should verify against actual code during first session
• User should review generated content for accuracy
• Schedule regular audits (monthly recommended)
