+
+# neo4j-memory
+
+Turns flat workspace cache files into a queryable health knowledge graph.
+
+## When to Use
+
+✅ Use when:
+
+- Paul asks to "save", "index", or "persist" health data to the graph
+- Paul asks a trend question: "how has my glucose trended?", "what active conditions do I have?"
+- After `health-records` or `med-pdf` runs, to ingest new files into the graph
+- `memory-diff` gives an incomplete answer — the graph has higher precision for structured facts
+
+## When NOT to Use
+
+❌ Don't use when:
+
+- Paul shares a PDF or screenshot → use `med-pdf` first, then ingest
+- Paul wants fresh portal data → use `health-records` first, then ingest
+- Paul wants news or social signal → use `myhealth-pulse`
+- Neo4j is not configured → tell Paul, route to `memory-diff`, stop
+
+## Setup
+
+1. Install the driver on the VM:
+   `sudo npm install --prefix /usr/lib/node_modules/openclaw neo4j-driver`
+2. Create connection config — see
+   [`references/connection-schema.md`](references/connection-schema.md)
+3. Initialize schema (once per database):
+   `node {baseDir}/scripts/schema-init.mjs`
+
+## Workflow
+
+### Ingest mode
+
+1. **Resolve config** via the precedence chain in
+   [`references/connection-schema.md`](references/connection-schema.md).
+   If not found, tell Paul to complete setup and stop.
+
+2. **Ingest cache files.** Run ingest on every FHIR and parsed-PDF file in
+   the workspace caches — the script deduplicates automatically via the
+   ingest log at `~/.openclaw/workspace/.neo4j-memory-cache/ingest-log.json`:
+
+   - Health-records FHIR:
+     `node {baseDir}/scripts/ingest.mjs --source health-records --file <path.json>`
+   - Med-pdf labs:
+     `node {baseDir}/scripts/ingest.mjs --source med-pdf-labs --file <outDir>`
+   - Med-pdf imaging:
+     `node {baseDir}/scripts/ingest.mjs --source med-pdf-imaging --file <outDir>`
+
+3. **Report** — nodes written, files skipped (already ingested), any errors.
+
+### Query mode
+
+1. **Resolve config.** If missing, route to `memory-diff` and say so.
+2. **Translate to Cypher.** Use the schema in
+   [`references/graph-schema.md`](references/graph-schema.md).
+3. **Execute:** `node {baseDir}/scripts/query.mjs --cypher "<query>"`
+4. **Reason over results.** Surface trends, flag abnormal values, compare to
+   prior entries. Don't return raw rows.
+
+## Scripts
+
+See [`references/scripts.md`](references/scripts.md) for flags, output
+schemas, and Cypher examples.
+
+## Examples
+
+See [`references/examples.md`](references/examples.md) for
+ingest-after-health-records, ingest-after-med-pdf, and trend query runs.
+
+## Privacy
+
+PHI written to Neo4j leaves the local VM when using AuraDB (cloud-hosted).
+Confirm this aligns with your use case before setup. To keep all data on the
+VM, run Neo4j Community Edition locally (`bolt://localhost:7687`) — same
+driver, same skill, different `uri`.
+
+Never forward graph results to external services, web search, or outbound
+notifications. PHI stays in the graph and in chat only.
+
+## Troubleshooting
+
+- **Connection refused** → verify `uri`, `username`, and the password env var;
+  see [`references/connection-schema.md`](references/connection-schema.md)
+- **`schema-init.mjs` errors on re-run** → idempotent by design; `IF NOT
+  EXISTS` guards every constraint and index
+- **Query returns empty** → confirm ingest ran:
+  `cat ~/.openclaw/workspace/.neo4j-memory-cache/ingest-log.json`
+- **`neo4j-driver` not found** → re-run setup step 1

+# Connection Schema
+
+The Neo4j connection config is a YAML file external to this skill. The skill
+reads it; the skill does not contain it. This keeps the repo generic and
+makes the skill deployable in multi-tenant runtimes (Aria) without code
+changes — only the resolved path differs per agent instance.
+
+## Where the config lives
+
+Resolution order, first hit wins:
+
+1. `skills.entries.neo4j-memory.config` in `openclaw.json` — used by
+   multi-tenant runtimes to inject a per-patient config path.
+2. `NEO4J_MEMORY_CONFIG` env var — absolute path to the YAML file; useful
+   for testing and CI.
+3. `~/.openclaw/workspace/memory/neo4j.yaml` — default for single-user Tula.
+
+The same skill code and the same scripts run in personal Tula and in Aria.
+Only the resolved path changes. In Aria, the runtime injects a per-patient
+config so each agent connects to its own isolated database.
+
+## Schema (v1)
+
+```yaml
+version: 1
+
+# Neo4j connection URI.
+# AuraDB Free (cloud):    neo4j+s://<id>.databases.neo4j.io
+# Local Community Edition: bolt://localhost:7687
+uri: neo4j+s://xxxxxxxx.databases.neo4j.io
+
+# Database name. Omit to use the default ("neo4j").
+# For Aria multi-tenant: set to "patient_<id>" for hard per-patient isolation
+# (requires Neo4j 4.0+ or AuraDB, which supports multiple databases).
+database: neo4j
+
+# Neo4j username (typically "neo4j" for AuraDB Free).
+username: neo4j
+
+# Name of the env var that holds the password. Never put the password itself
+# in this file — the file may be read-accessible to other processes.
+password_env: NEO4J_MEMORY_PASSWORD
+```
+
+Set the password before running any script:
+
+```bash
+export NEO4J_MEMORY_PASSWORD="your-auradb-password"
+```
+
+For persistence across sessions, add it to `~/.openclaw/workspace/.env` or
+the system-level env config on the VM.
+
+## Personal Tula vs. multi-tenant
+
+| Aspect | Personal Tula | Multi-tenant (Aria) |
+|---|---|---|
+| Config path | `~/.openclaw/workspace/memory/neo4j.yaml` | resolved per-agent via `openclaw.json` |
+| Who sets it | the user, by hand | provisioned by the Aria identity service |
+| Database | single `neo4j` database | `patient_<id>` per agent — hard isolation |
+| Password env | set in shell profile or `.env` | injected per-agent by the runtime |
+| Skill code | identical | identical |
+
+Aria's isolation guarantee comes from per-agent credentials that only have
+access to that patient's database. The skill is unaware of which deployment
+it's running in. That's the point.
+
+## What does NOT belong in this file
+
+- The password itself — always use `password_env`
+- Patient identity, conditions, medications, or any PHI
+- Skill logic, routing rules, or topic lists
+
+Those live in their respective workspace memory files.

+# Scripts Reference
+
+All scripts live in `{baseDir}/scripts/`. Run them from anywhere — they take
+absolute paths. All scripts read connection config via the precedence chain
+in [`connection-schema.md`](connection-schema.md).
+
+## config.mjs
+
+Shared config loader imported by the other three scripts. Not invoked
+directly. Exports `resolveConfig()` which returns
+`{ uri, database, username, password, workspacePath }`.
+
+Reads `~/.openclaw/workspace/memory/neo4j.yaml` (or the path from
+`NEO4J_MEMORY_CONFIG` env var). The `password` value is resolved from the
+env var named by `password_env` in the config file.
+
+## schema-init.mjs
+
+```
+node {baseDir}/scripts/schema-init.mjs
+```
+
+Creates Neo4j uniqueness constraints and indexes. Idempotent — uses
+`IF NOT EXISTS` guards on every statement. Safe to re-run at any time.
+
+### Output (stdout JSON)
+
+```json
+{ "ok": true, "constraints": 5, "indexes": 3 }
+```
+
+Run this once after setup, and again after any schema changes (new node
+labels or indexes added to future versions).
+
+## ingest.mjs
+
+```
+node {baseDir}/scripts/ingest.mjs --source <type> --file <path>
+```
+
+Writes health data from a workspace cache file into the Neo4j graph using
+`MERGE` — fully idempotent. Tracks processed files in an ingest log at
+`~/.openclaw/workspace/.neo4j-memory-cache/ingest-log.json` and skips
+files that have already been ingested (same path + same mtime).
+
+### Source types
+
+| `--source` | `--file` | What it reads |
+|---|---|---|
+| `health-records` | Path to a FHIR R4 JSON file under `.health-records-cache/` | Observations, Conditions, MedicationStatements |
+| `med-pdf-labs` | Path to a `labs.json` file OR its parent `<outDir>` | Lab values from `parse_labs.mjs` output |
+| `med-pdf-imaging` | Path to an `imaging.json` file OR its parent `<outDir>` | Radiology reports from `parse_imaging.mjs` output |
+
+### Output (stdout JSON)
+
+```json
+{ "ok": true, "source": "health-records", "file": "/path/to/file.json",
+  "nodesWritten": 14, "skipped": false }
+```
+
+When a file was already ingested and hasn't changed:
+
+```json
+{ "ok": true, "skipped": true, "reason": "already ingested",
+  "file": "/path/to/file.json" }
+```
+
+### Ingest log
+
+Located at `~/.openclaw/workspace/.neo4j-memory-cache/ingest-log.json`.
+Each entry records the file path, source type, ingest timestamp, file mtime,
+and nodes written. The log is append-only; ingest.mjs never removes entries.
+
+## query.mjs
+
+```
+node {baseDir}/scripts/query.mjs --cypher "<cypher statement>" [--limit 50]
+```
+
+Executes a read-only Cypher query against the graph and returns results as
+JSON. Use the patterns in [`graph-schema.md`](graph-schema.md) to build
+queries.
+
+### Flags
+
+| Flag | Default | Notes |
+|---|---|---|
+| `--cypher` | required | Cypher query string |
+| `--limit` | 50 | Max rows to return |
+
+### Output (stdout JSON)
+
+```json
+{
+  "ok": true,
+  "count": 3,
+  "rows": [
+    { "date": "2026-01-15", "value": "95", "unit": "mg/dL", "abnormal": false },
+    { "date": "2026-03-02", "value": "108", "unit": "mg/dL", "abnormal": false },
+    { "date": "2026-05-10", "value": "118", "unit": "mg/dL", "abnormal": true }
+  ]
+}
+```
+
+### Note on write queries
+
+`query.mjs` does not block write queries, but the skill should only use it
+for reads. Writes go through `ingest.mjs`, which manages deduplication and
+the ingest log.
