ā” IMMEDIATE TRIGGER: Missing .memory-engineering/config.json = NEW PROJECT = INIT NOW!
MANDATORY WORKFLOW (failure = context death):
1. DETECT ā No config.json? EXECUTE IMMEDIATELY (don't wait, don't ask)
2. DEEP-SCAN entire codebase in <3 seconds:
- package.json/requirements.txt/go.mod ā Extract EVERYTHING
- README.md/docs/*.md ā Understand PURPOSE & VISION
- src/index.* or main.* ā Map ALL entry points
- test/* ā Learn expected behaviors
- .env.example ā Note required services
3. AUTO-GENERATE all 7 memories (your survival depends on this):
- projectbrief: "Building [WHAT] to solve [WHY]"
- productContext: "Users need [PROBLEM] solved by [SOLUTION]"
- systemPatterns: "Architecture: [PATTERN], Flow: [DESIGN]"
- techContext: "Stack: [FULL LIST], Constraints: [LIMITS]"
- codebaseMap: "Structure: [COMPLETE TREE]"
- activeContext: "TODOs: [ALL], Status: [CURRENT], Next: [ACTION]"
- progress: "Working: [LIST], Broken: [LIST], Missing: [LIST]"
4. CRITICAL HANDOFF ā sync_code (AUTO-DETECTS language patterns!)
5. VERIFICATION HANDOFF ā read_all (confirm memories created)
ā ļø CONSEQUENCE OF FAILURE: Your next session starts completely blind!

ā Retrieves single memory with metadata
ā Shows last update time and relationships
**UPDATE MEMORY:**
memory_engineering_memory --name activeContext --content "..."
ā Updates with timestamp and version tracking
ā Validates structure automatically
ā CRITICAL: Update activeContext EVERY 3-5 MINUTES!

š§ RETRIEVAL MASTERY - Execute these cascades based on context:
š“ DEBUGGING CASCADE (when fixing issues):
1. search --query "[error message]" ā Check if seen before
2. search --query "[component name]" --codeSearch "implements" ā Find the broken code
3. search --query "[related feature]" ā Check memory context
4. PARALLEL: Search activeContext + systemPatterns + error logs
ā” FEATURE CASCADE (when building):
1. search --query "[feature name]" ā Check if exists
2. search --query "[similar concept]" --codeSearch "similar" ā Find patterns
3. search --query "[tech/library]" ā Check techContext mentions
4. PARALLEL: Search projectbrief + progress + existing code
šÆ UNDERSTANDING CASCADE (when learning):
1. search --query "[what is X]" ā Check documented knowledge
2. search --query "[X implementation]" --codeSearch "pattern" ā See it in action
3. search --query "[X decision]" ā Find historical context
š SEMANTIC EXPANSION (automatic):
"auth" ā ALSO SEARCHES: authentication, login, JWT, token, session
"db" ā ALSO SEARCHES: database, MongoDB, schema, model
"error" ā ALSO SEARCHES: bug, issue, problem, failure, exception

š§ TRUTH: Without embeddings, search is BLIND. With embeddings, search finds EVERYTHING!
š AUTOMATIC TRIGGERS (no permission needed):
š After init ā FULL SCAN:
ā AUTO-DETECTS: JS/TS/Python/Go/Ruby/Rust/Java/C++
ā Scans ENTIRE codebase in seconds
ā Creates searchable knowledge graph
ā Your code becomes QUERYABLE!
š Files changed ā INSTANT SYNC:
- Created files ā sync patterns:["new/file/path/*"]
- Deleted files ā auto-cleanup embeddings
- Modified files ā regenerate chunks
- Moved files ā update all references
ā° TIME-BASED TRIGGERS:
- Session start + last sync >24h ā FULL RESYNC
- Before ANY code search ā freshness check
- Every 10-15 file edits ā incremental sync
- After git pull/merge ā sync changes
šÆ SMART DEFAULTS (v${version} PRODUCTION-READY):

- includeTests: TRUE (tests = documentation!)
- forceRegenerate: When things feel broken
