+# ClinicalMatch AI — Project Memory
+Full-stack clinical trial matching agent for "Agents Assemble: Healthcare AI Endgame Challenge" on Prompt Opinion. Submission uses FHIR R4, MCP, and A2A standards.
+**Stack:** FastAPI + Neo4j + LangChain GraphRAG + Next.js 16 + Recharts + Leaflet
+**LLM:** aimlapi.com (OpenAI-compatible) with claude-opus-4-7. Never use Anthropic SDK directly.
+## Completed features
+- `/intake` — SI-unit clinical intake form (no patient ID), scores against graph trials, optional graph save
+- Trial Finder (`/`) — real-time CT.gov sorted by recency, passive graph enrichment on every search, Graph Intelligence panel per trial
+- `/screening` — FHIR patient combobox loading 500 graph patients, A2A pipeline (5 states)
+- `/recruitment` — kanban board, AI outreach generation (3 channels)
+- `/dashboard` — KPI cards, enrollment funnel, demographics pie chart
+- `/map` — Leaflet site map with patient density clusters
+- `/graph` — GraphRAG with custom Cypher prompt
+- 500 synthetic patients seeded, ~250 real NCT trials, ~9,100 ELIGIBLE_FOR edges
+- MCP server (6 tools, stdio transport)
+- `trial_enrichment.py` — passive upsert on search, batch eligible-patient counts, similar-trials graph walk
+- `intake_matching.py` — BIOMARKER_REGISTRY, SI unit conversion, regex ECOG + lab threshold parsing
+## Known constraints
+- Turbopack broken — always `next dev --webpack`
+- `next/font/google` removed (hangs compilation) — use Tailwind `font-sans`
+- Sync CT.gov wrappers use `httpx.Client` not `asyncio.run()` (breaks in FastAPI event loop)
+- Leaflet uses raw API via useEffect, not react-leaflet (SSR issues)
+- Mock FHIR patients: P001–P005 (fhir_adapter.py). Graph patients: P_C50_0001 etc.
+- `suppressHydrationWarning` on `<body>` in layout.tsx for Grammarly extension
+- After Python file changes, uvicorn may need manual restart if --reload doesn't trigger
+See `CLAUDE.md` at repo root for full agent instructions.

+# ClinicalMatch AI — Agent Instructions
+> Project memory (build state, completed features, constraints) is also tracked in `.claude/project_memory.md` in this repo.
+This is a hackathon submission for **"Agents Assemble: Healthcare AI Endgame Challenge"** on the Prompt Opinion platform. Judging criteria: MCP compliance, A2A workflow, FHIR R4 standards, AI quality, impact, feasibility.
+## Stack at a glance
+| Layer | Technology |
+|---|---|
+| Backend | FastAPI (Python 3.12), uvicorn |
+| Graph DB | Neo4j Community 5.x via bolt |
+| LLM | claude-opus-4-7 via aimlapi.com (OpenAI-compatible) |
+| GraphRAG | LangChain `GraphCypherQAChain` + custom Cypher prompt |
+| Frontend | Next.js 16 (webpack mode), React 19, Tailwind CSS 3, Recharts, Leaflet |
+| Standards | FHIR R4 · MCP (stdio) · A2A state machine |
+## Critical: LLM API
+**Never use the Anthropic SDK directly.** All LLM calls go through aimlapi.com or a compatible alternative using the OpenAI-compatible interface:
+```python
+from openai import OpenAI
+client = OpenAI(
+    api_key=os.getenv("OPENAI_API_KEY"),
+    base_url=os.getenv("OPENAI_BASE_URL", "https://ai.aimlapi.com/v1"),
+)
+model = os.getenv("OPENAI_MODEL", "claude-opus-4-7")
+```
+See `backend/llm_client.py` for the canonical pattern. Do not add `import anthropic` anywhere.
+## Starting the services
+```bash
+# Backend — always use --reload for hot reload
+cd backend && source venv/bin/activate
+uvicorn main:app --reload --port 8000
+# Frontend — always use --webpack (Turbopack is broken on this system)
+cd frontend && npm run dev   # runs: next dev --webpack
+# MCP server (separate process, stdio transport)
+cd backend && python mcp_server.py
+# Seed graph data (~15 min first run)
+curl -X POST http://localhost:8000/seed
+```
+After changing backend Python files, uvicorn `--reload` should pick them up. If a 404 appears for a newly-added endpoint or old errors persist, the server needs a manual restart — kill the process and re-run the uvicorn command.

+## Neo4j graph schema
+```
+(Patient)         id, name, age, sex, ecog, condition, city, state, ethnicity,
+                  biomarkers[], medications[], source, stage
+(Trial)           id (NCT), title, condition, phase, status, sponsor,
+                  eligibility_criteria, min_age, max_age, sex, enrollment,
+                  start_date, completion_date, last_updated, ctgov_url

+(Biomarker)       id (e.g. HER2_POS), name (e.g. "HER2 Positive")
+(Medication)      id (e.g. TAMOXIFEN), name
+(StudySite)       id, name, city, state, lat, lon, trials, enrolled, capacity
+Relationships:
+  (Patient)-[:ELIGIBLE_FOR {score}]->(Trial)
+  (Patient)-[:HAS_DIAGNOSIS]->(Diagnosis)
+  (Patient)-[:HAS_BIOMARKER]->(Biomarker)
+  (Patient)-[:TAKES_MEDICATION]->(Medication)
+  (Trial)-[:LOCATED_AT]->(StudySite)
+```
+**Graph scale after seeding:** ~500 patients, ~250 trials, ~9,100 ELIGIBLE_FOR edges.
+Patient IDs from seeder: `P_C50_0001` (breast), `P_C61_0001` (prostate), etc.
+Mock FHIR patients: `P001`–`P005` (used by screening/workflow pages).
+## Key backend modules
+### `clinicaltrials_api.py`
+- `search_trials()` — async, `sort=LastUpdatePostDate:desc`
+- `get_trial_details()` — async
+- `search_trials_sync()` / `get_trial_details_sync()` — sync using `httpx.Client` (NOT `asyncio.run()`). Safe to call from both sync functions and FastAPI async handlers.
+- `_normalize_study()` — extracts `last_updated`, `ctgov_url` in addition to core fields.
+**Do not** use `asyncio.run()` inside these sync wrappers — it breaks when called from a running FastAPI event loop. The sync wrappers use `httpx.Client` directly.
+### `intake_matching.py`
+Implements SI-unit clinical intake → trial eligibility matching without requiring a patient ID:
+- `BIOMARKER_REGISTRY` — maps graph node IDs to labels and eligibility text search terms
+- `score_intake_against_trial()` — weighted scoring: age (25), sex (15), ECOG (15), biomarkers (30), labs (15)
+- `_check_labs()` — parses thresholds from eligibility criteria text, converts SI units (creatinine μmol/L ↔ mg/dL, bilirubin μmol/L ↔ mg/dL)
+- `save_intake_as_patient()` — persists intake as `Patient` node for long-term graph enrichment
+### `trial_enrichment.py`
+- `enrich_trials_from_search()` — called as a `BackgroundTask` on every `/api/v1/trials/search` response; upserts Trial + StudySite nodes
+- `get_eligible_patient_counts()` — batch graph query, returns `{nct_id: count}`
+- `get_graph_intelligence()` — per-trial: eligible count + top biomarkers + similar trials
+### `graphrag.py`
+Uses a custom `_CYPHER_PROMPT` with explicit schema examples. Critical rules in the prompt:
+- Biomarker lookups use `id` property (`{id: 'HER2_POS'}`), never `{name: 'HER2', status: 'positive'}`
+- Condition lookups use lowercase on Trial nodes
+- Patient eligibility always via `(Patient)-[:ELIGIBLE_FOR]->(Trial)`
+### `a2a_workflow.py`
+Five-state machine: `INGESTING → PARSING_PROTOCOL → MATCHING → SCORING → RECRUITING`
+- Calls `search_trials_sync()` / `get_trial_details_sync()` — these are safe (use httpx.Client)
+- `run_pipeline()` is synchronous; called from async FastAPI endpoint without `await`
+## Key frontend pages
+### `/intake` — Eligibility Check
+The primary self-service interface. Accepts raw clinical data in SI units; no patient ID needed.
+- Six sections: Diagnosis & Demographics, Biomarkers, Lab Values, Treatment History
+- Biomarker registry loaded from `GET /api/v1/intake/biomarkers`
+- Submits to `POST /api/v1/intake/match`
+- Optional "Save to graph" checkbox persists profile as Patient node
+### `/` — Trial Finder
+- Sorted by `LastUpdatePostDate:desc` (most recently updated first)
+- Each search result triggers background graph enrichment
+- Expanded cards show Graph Intelligence panel: eligible patient count, top biomarkers, similar trials
+- Direct ClinicalTrials.gov link per trial
+### `/screening` — Patient Screening
+- Patient ID field is a `<input list="...">` combobox loading from `GET /api/v1/graph/patients`
+- NCT ID field is a combobox with quick-pick suggestions
+- Validates non-empty inputs before submitting
+- Two modes: Single Trial Screen and A2A Full Pipeline
+## API endpoints (key ones)
+```
+GET  /api/v1/trials/search          — real-time CT.gov search, sorted by recency, graph-enriched
+POST /api/v1/intake/match           — SI-unit clinical intake → ranked trial matches
+GET  /api/v1/intake/biomarkers      — biomarker registry for the intake form
+GET  /api/v1/trials/{nct_id}/intelligence — graph-derived insights per trial
+GET  /api/v1/graph/patients         — query Neo4j for seeded patient IDs
+POST /api/v1/patients/{id}/screen/{nct_id} — screen FHIR patient against trial
+POST /api/v1/workflow/run           — run full A2A pipeline
+GET  /api/v1/analytics/kpi         — dashboard KPIs
+GET  /api/v1/map/data               — site coordinates + patient clusters
+POST /api/v1/graph/query            — GraphRAG natural language
+POST /seed                          — trigger full graph seeding
+GET  /api/v1/graph/stats            — node/edge counts

+```
+## Known issues and constraints
+- **Turbopack is broken** on this machine — always use `next dev --webpack`. Never suggest `next dev` without `--webpack`.
+- **`next/font/google`** causes compilation to hang (network request during bundling). Geist font is installed as a package but the `next/font/google` import is removed. Use plain Tailwind `font-sans`.
+- **`asyncio.run()` from async context** — the sync CT.gov wrappers use `httpx.Client` to avoid this. Never re-introduce `asyncio.run()` into the sync wrappers; it will fail when called from FastAPI's running event loop.
+- **Leaflet SSR** — `MapComponent.tsx` uses raw Leaflet (not react-leaflet) via `useEffect`. The `MapComponent` dynamic import has `ssr: false`. Do not switch to react-leaflet's `MapContainer`.
+- **`suppressHydrationWarning`** on `<body>` in `layout.tsx` — required for Grammarly browser extension compatibility.
+- **Mock FHIR patients** (P001–P005) live in `fhir_adapter.py`. The 500 seeded graph patients (`P_C50_0001` etc.) are in Neo4j only. The screening page loads graph patients from `GET /api/v1/graph/patients` for the combobox.
+## Adding new features
+1. **New backend route**: add to `main.py`, import the module at the top, add a Pydantic request model if needed
+2. **New API function**: add a typed function to `frontend/src/lib/api.ts`
+3. **New page**: create `frontend/src/app/<name>/page.tsx`, add to `nav` array in `Sidebar.tsx`
+4. **Graph schema change**: update `neo4j_setup.py` constraints/indexes, update `_CYPHER_PROMPT` in `graphrag.py` with the new node/property examples
+5. **New biomarker**: add to `BIOMARKER_REGISTRY` in `intake_matching.py` and to `BM_GROUPS` in `frontend/src/app/intake/page.tsx`
+## Demo script (for judges)
+1. `GET /api/v1/graph/stats` — confirm 500+ patients and 9,100+ edges
+2. `/` — search "breast cancer" → observe recency sort, graph-matched patient count badges
+3. Expand a trial → Graph Intelligence panel shows eligible patients, top biomarkers, similar trials
+4. `/intake` — enter: Age 52, Female, ECOG 1, HER2+, Hgb 12.5 g/dL, Creatinine 88 μmol/L → ranked trials with pass/fail breakdown
+5. `/screening` — select P_C50_0001 from combobox → run A2A Pipeline → observe 5-state machine
+6. `/recruitment` — kanban board, generate PCP letter outreach
+7. `/dashboard` — KPI cards, enrollment funnel, demographics
+8. `/graph` — ask "which patients are eligible for breast cancer trials?"
+9. In Prompt Opinion: call MCP tool `find_trials(condition="breast cancer")`

+# ClinicalMatch AI — Precision Clinical Trial Matching & Recruitment Agent
+**"Agents Assemble: Healthcare AI Endgame Challenge"** — Prompt Opinion platform
+Standards: **FHIR R4 · MCP · A2A**
+> 80% of clinical trials fail to meet enrollment deadlines. 85% of eligible patients are never identified. This agent directly addresses that.
+---
+## What it does
+ClinicalMatch AI is a full-stack AI agent that matches patients to recruiting clinical trials using a knowledge graph, real-time data from ClinicalTrials.gov, and structured clinical eligibility scoring.
+**Key capabilities:**
+| Feature | Description |
+|---|---|
+| **Eligibility Check** | Individual enters raw clinical data (age, labs in SI units, biomarkers) — no patient ID required — and receives ranked, explainable trial matches |
+| **Trial Finder** | Real-time search of ClinicalTrials.gov sorted by most recently updated; results auto-ingest into the knowledge graph |
+| **Graph Intelligence** | Per-trial: eligible patient count, top biomarkers among matches, similar trials via graph-neighborhood walk |
+| **A2A Pipeline** | 5-state orchestration (INGEST → PARSE → MATCH → SCORE → RECRUIT) for FHIR patient profiles |
+| **Recruitment Hub** | Kanban board tracking patients through IDENTIFIED → ENROLLED; generates personalized outreach (PCP letter, patient email, social post) |
+| **GraphRAG** | Natural language queries over the knowledge graph ("which patients are eligible for breast cancer trials?") |
+| **MCP Server** | 6 tools callable by Prompt Opinion directly via stdio transport |

+**Data sources (all free, no auth):**
+| Source | Data |
+|---|---|
+| ClinicalTrials.gov v2 | Real recruiting NCT trials, sorted by recency |
+| RxNorm (NIH) | Medication RxCUI codes |
+| ICD-10 CM (NLM) | Cancer diagnosis codes |
+| PubMed (NCBI) | Supporting literature PMIDs |
+| OpenFDA | Drug labels and adverse events |
+| Synthetic | 500 realistic patient profiles matched to real trials |
+---
+## Graph Knowledge Base
+After seeding, the Neo4j graph contains:
+| Node type | Count | Key properties |
+|---|---|---|
+| Patient | 500 | age, sex, ECOG, condition, city, biomarkers[], medications[] |
+| Trial | ~250 | NCT ID, eligibility criteria, phase, last_updated |
+| Diagnosis | ~130 | ICD-10 codes across 10 oncology conditions |
+| Biomarker | 20 | HER2+/−, EGFR, ALK, BRCA1/2, MSI-H, FLT3, etc. |
+| Medication | 16 | Trastuzumab, Pembrolizumab, Olaparib, etc. |
+| StudySite | ~200 | lat/lon coordinates |
+| **ELIGIBLE_FOR edges** | **~9,100** | score, linking patients to trials |
+The graph grows passively — every Trial Finder search automatically upserts new Trial and StudySite nodes. Every Eligibility Check submission (with "Save to graph" enabled) adds a new Patient node with biomarker edges.
+---
+## Clinical Eligibility Check (SI Units)
+The `/intake` page accepts raw clinical data — no patient ID or account required. Fields:
+**Demographics:** Age (years), Sex, ECOG performance status (0–4), Disease stage (I–IV)
+**Biomarker status (toggles):**
+- Breast/Gynecologic: HER2+/−, ER+, PR+, BRCA1/2 mutation, Triple-Negative
+- Lung (NSCLC): EGFR mutation, ALK, ROS1 rearrangement, PD-L1
+- GI/Colorectal: MSI-High, KRAS wild-type, BRAF V600E
+- Hematology: FLT3, IDH1/2, BCR-ABL
+**Lab values (SI units):**
+| Field | Unit | Conversion |
+|---|---|---|
+| Haemoglobin | g/dL | — |
+| WBC | ×10⁹/L | — |
+| ANC | ×10⁹/L | — |
+| Platelets | ×10⁹/L | — |
+| Creatinine | **μmol/L** | auto-converted ÷88.4 → mg/dL for trial text |
+| eGFR | mL/min/1.73m² | — |
+| Bilirubin | **μmol/L** | auto-converted ÷17.1 → mg/dL for trial text |
+| ALT / AST | U/L | — |
+Matching score breakdown:
+- **Age** 25 pts — compared against trial min/max age
+- **Sex** 15 pts — compared against trial sex restriction
+- **ECOG** 15 pts — extracted via regex from eligibility criteria text
+- **Biomarkers** 30 pts — checks whether biomarker terms appear in trial eligibility text
+- **Lab values** 15 pts — parses thresholds from text, converts SI units, checks patient values
