Project Context Loader

Priority: HIGH - Use before any workflow or code generation Version: 1.1.0

When to Use

BEFORE:

workflow:start or any implementation
Any code generation or new files
Refactoring or writing tests

SKIP only for: Simple questions (no code), when session-context.toon already loaded

Loading Process

1. Check for Cached Context

# If session context exists and is recent (< 1 hour), use it
if [ -f ".claude/session-context.toon" ]; then
  Read .claude/session-context.toon
  # Skip full scan
fi

2. Generate Session Context (If Missing)

Scan Codebase Patterns

# File naming convention
ls src/components/ | head -5  # PascalCase or kebab-case?

# Import style
Grep: "^import.*from ['\"]@/" --type ts  # Absolute paths?
Grep: "^import.*from ['\"]\.\./" --type ts  # Relative paths?

# Export pattern
Grep: "^export default" --type ts
Grep: "^export (const|function)" --type ts

# Error handling
Grep: "Result<|Either<" --type ts  # Functional?
Grep: "try.*catch" --type ts  # Exception-based?

Generate TOON File

Write to .claude/session-context.toon:

# Session Context - Auto-generated
# Generated: {timestamp}

---

project:
  name: {from package.json}
  stack: {detected}

patterns[6]{type,convention,example}:
  file_naming,{PascalCase|kebab-case},{example}
  imports,{absolute|relative},{example}
  exports,{named|default},{example}
  errors,{result|exceptions},{example}
  testing,{jest|vitest},{example}
  styling,{tailwind|css-modules},{example}

workflow:
  phase: {current}
  feature: {name}
  branch: {git branch}

3. Load Project-Specific Config

Location: .claude/project-contexts/[project]/

File	Contains
`project-config.yaml`	Tech stack, integrations
`conventions.md`	Override patterns (optional)
`rules.md`	Project-specific rules

4. Merge Priority

session-context.toon (cached patterns)
  ↓
project-contexts/conventions.md (overrides)
  ↓
Aura Frog core rules (defaults)

Session Context Template

Token Efficiency

Approach	Tokens
Full convention docs	~500-1000
Session context TOON	~100-150
Savings	80-85%

Commands

Generate Context Manually

bash scripts/context-compress.sh

Clear Context (Force Rescan)

rm .claude/session-context.toon

If Context Missing

⚠️ **Project context not found!**

Generating session-context.toon from codebase scan...
Run `project:init` for full project config.
