Phase 3: Integration Test Design ✅

Test 1: Create → Save → Recall Workflow

Purpose: Validate the complete end-to-end flow of the context recall system.

Steps:

1. Create conversation context using compress_conversation_summary()
2. Save compressed context to database via POST /api/conversation-contexts
3. Recall context via GET /api/conversation-contexts/recall?project_id={id}
4. Verify format_for_injection() output is ready for Claude prompt

Validation:

• Context saved successfully with compressed JSON
• Recall endpoint returns formatted markdown string
• Token count is optimized for Claude prompt injection
• All critical information preserved through compression

Test 2: Cross-Machine Context Sharing

Purpose: Test context recall across different machines working on the same project.

Steps:

1. Create contexts from Machine 1 with machine_id=machine1_id
2. Create contexts from Machine 2 with machine_id=machine2_id
3. Query by project_id (no machine filter)
4. Verify contexts from both machines are returned and merged

Validation:

• Machine-agnostic project context retrieval
• Contexts from different machines properly merged
• Session/machine metadata preserved for audit trail

---

Phase 4: Hook Simulation Test Design ✅

Hook 1: user-prompt-submit

Scenario: Claude user submits a prompt, hook queries context for injection.

Steps:

1. Simulate hook triggering on prompt submit
2. Query /api/conversation-contexts/recall?project_id={id}&limit=10&min_relevance_score=5.0
3. Measure query performance
4. Verify response format matches Claude prompt injection requirements

Success Criteria:

• Response time < 1 second
• Returns formatted context string
• Context includes project-relevant snippets and decisions
• Token-efficient for prompt budget

Hook 2: task-complete

Scenario: Claude completes a task, hook saves context to database.

Steps:

1. Simulate task completion
2. Compress conversation using compress_conversation_summary()
3. POST compressed context to /api/conversation-contexts
4. Measure save performance
5. Verify context saved with correct metadata

Success Criteria:

• Save time < 1 second
• Context properly compressed before storage
• Relevance score calculated correctly
• Tags and decisions extracted automatically

---

Phase 5: Project State Test Design ✅

Test 1: Project State Upsert Workflow

Purpose: Validate upsert functionality ensures one state per project.

Steps:

1. Create initial project state with 25% progress
2. Update project state to 50% progress using upsert endpoint
3. Verify same record updated (ID unchanged)
4. Update again to 75% progress
5. Confirm no duplicate states created

Validation:

• Upsert creates state if missing
• Upsert updates existing state (no duplicates)
• updated_at timestamp changes
• Previous values overwritten correctly

Test 2: Next Actions Tracking

Purpose: Test dynamic next actions list updates.

Steps:

1. Set initial next actions: ["complete tests", "deploy"]
2. Update to new actions: ["create report", "document findings"]
3. Verify list completely replaced (not appended)
4. Verify JSON structure maintained

---

Phase 6: Usage Tracking Test Design ✅

Test 1: Snippet Usage Tracking

Purpose: Verify usage count increments on retrieval.

Steps:

1. Create snippet with usage_count=0
2. Retrieve snippet 5 times via GET /api/context-snippets/{id}
3. Retrieve final time and check count
4. Expected: usage_count=6 (5 + 1 final)

Validation:

• Every GET increments counter
• Counter persists across requests
• Used for relevance score calculation

Test 2: Relevance Score Calculation

Purpose: Validate relevance score weights usage appropriately.

Test Data:

• Snippet A: usage_count=2, importance=5
• Snippet B: usage_count=20, importance=5

Expected:

• Snippet B has higher relevance score
• Usage boost (+0.2 per use, max +2.0) increases score
• Age decay reduces score over time
• Important tags boost score
