PRISM - Immediate Action Plan

Goal: Get to a working MVP in 1 week Status: 75% Complete → 95% Complete

Phase 1: Critical Fixes (Days 1-2)

Fix 1: TypeScript Compilation Errors (4 hours)

Problem:

src/vector-db/MemoryVectorDB.ts(334,26): error TS1003: Identifier expected.
# 50+ cascading syntax errors

Solution:

# Step 1: Locate the syntax error
cd /home/user/prism
grep -n "Example:" src/vector-db/MemoryVectorDB.ts | head -5

# Step 2: Fix template literal in comment (likely line 334)
# The issue is probably an unclosed string or template literal
# in a JSDoc comment or markdown-style documentation

# Step 3: Test compilation
npm run typecheck

# Step 4: Build if successful
npm run build:ts

Expected Outcome:

✅ TypeScript compiles without errors
✅ dist/ directory created
✅ MCP server compiled to dist/mcp/cli.js

Fix 2: Implement Real File Indexing (8 hours)

Current State:

// daemon/server.js - Mock search only
simpleSearch(query) {
  return [{
    file: 'README.md',
    content: `Found search query: "${query}"`,
    score: 0.9,
    line: 1
  }];

Update: /home/user/prism/claude-code-plugin/daemon/server.js

Test:

# Start server
cd /home/user/prism/claude-code-plugin
node daemon/server.js

# Test indexing (in another terminal)
curl http://localhost:8080/project
curl -X POST http://localhost:8080/index
curl -X POST http://localhost:8080/search -d '{"query":"function"}' | jq '.'

Expected Outcome:

✅ Files indexed to .prism/index.json
✅ Search returns real results from project
✅ Results ranked by relevance

Phase 2: MCP Integration (Days 3-4)

Test:

curl http://localhost:8080/tools/list | jq '.'
curl -X POST http://localhost:8080/tools/call -d '{"name":"search_repo","arguments":{"query":"error","limit":5}}' | jq '.'

Expected Outcome:

✅ MCP protocol working
✅ Claude Code can discover tools
✅ Tools return real results

Phase 3: Polish & Testing (Day 5)

Fix 4: Add Persistence & Auto-reload (2 hours)

Features:

✅ Index saved on shutdown
✅ Index loaded on startup
✅ Incremental updates (optional)

Already implemented in file-indexer.js above!

Fix 5: Testing & Validation (4 hours)

Test Suite:

# Create test script
cd /home/user/prism/claude-code-plugin
cat > test-integration.sh <<'EOF'
#!/bin/bash

echo "=== PRISM Integration Test Suite ==="

# Start server in background

# Test 1: Health check

# Test 2: Project info

# Cleanup
kill $SERVER_PID
echo "=== Tests Complete ==="
EOF

chmod +x test-integration.sh
./test-integration.sh

Phase 4: Documentation (Day 6-7)

Fix 6: Update Documentation (4 hours)

Update Files:

README.md - Add "Known Limitations" section
QUICK-START.md - Update with current reality
API.md - Document HTTP endpoints
TROUBLESHOOTING.md - Common issues and fixes

Known Limitations Section:

## Known Limitations (v1.0)

✅ **What Works:**
- Basic keyword search
- Project detection
- File indexing
- HTTP API
- MCP protocol

⚠️ **What's Limited:**
- Search is keyword-based (not semantic)
- No vector embeddings (planned for v2.0)
- No file watcher yet (manual reindex)
- Single project only

❌ **What's Not Implemented:**
- WASM chunking
- Incremental indexing
- Team collaboration

Success Criteria

Minimum Viable Product (MVP)

Must Have:

Nice to Have:

File watcher
Semantic search (v2.0)
Incremental indexing
Performance metrics

Definition of Done

When can we say "it works"?

✅ Server starts without errors
✅ Project auto-detected
⏳ Files indexed automatically
⏳ Search returns relevant results
⏳ MCP tools work in Claude Code
⏳ Index persists across restarts
⏳ All integration tests pass

Current Status: 2/7 complete (28%) Target: 7/7 complete (100%) ETA: 5 working days

Timeline

Day	Tasks	Hours	Status
Day 1	Fix TypeScript errors	4h	⏳ Pending
Day 2	Implement file indexer	8h	⏳ Pending
Day 3	Replace mock search	4h	⏳ Pending
Day 3	Add MCP tools	4h	⏳ Pending
Day 4	Add persistence	2h	⏳ Pending
Day 4	Write tests	4h	⏳ Pending
Day 5	Run tests + fix bugs	6h	⏳ Pending
Day 6-7	Update docs	4h	⏳ Pending
Total		36h	0% Done

Risk Mitigation

If TypeScript Fix Takes Longer

Plan B: Skip TypeScript compilation for now

Use JavaScript-only plugin
Add semantic search later as v2.0
Focus on working MVP first

If Integration is Complex

Plan B: Start with HTTP API only

Document as "HTTP API mode"
Add MCP tools as optional enhancement
Users can call HTTP endpoints directly

If Performance is Poor

Plan B: Add indexing limits

Only index files <100KB
Only index most common file types
Add configuration for max files
