Prerequisites
surreal CLI -- brew install surrealdb/tap/surreal (macOS) or see install docs
Python 3.10+ -- Required for skill scripts
uv -- brew install uv (macOS) or pip install uv or see uv docs
Optional:
Docker -- For containerized SurrealDB instances (docker run surrealdb/surrealdb:v3)
SDK of choice -- JavaScript, Python, Go, Rust, Java, .NET, C, PHP, or Dart
Security note: This skill documents package-manager and container installs
only. Prefer auditable installs through Homebrew, apt/dnf, Cargo, npm, or
Docker rather than remote one-line shell installers.
Quick Start
Credential warning: Examples below use root/root for local development
only. Never use default credentials against production or shared instances.
Create scoped, least-privilege users for non-local environments.
# Start SurrealDB in-memory for LOCAL DEVELOPMENT ONLY
surreal start memory --user root --pass root --bind 127.0.0.1:8000
# Start with persistent RocksDB storage (local dev)
surreal start rocksdb://data/mydb.db --user root --pass root
# Start with SurrealKV (time-travel queries supported, local dev)
surreal start surrealkv://data/mydb --user root --pass root
# Connect via CLI REPL (local dev)
surreal sql --endpoint http://localhost:8000 --user root --pass root --ns test --db test# Import a SurrealQL file
surreal import --endpoint http://localhost:8000 --user root --pass root --ns test --db test schema.surql
# Export the database
surreal export --endpoint http://localhost:8000 --user root --pass root --ns test --db test backup.surql
# Check version
surreal version
# Run the skill health check
uv run {baseDir}/scripts/doctor.py
Environment Variables
Variable
Description
Default
SURREAL_ENDPOINT
SurrealDB server URL
http://localhost:8000
SURREAL_USER
Root or namespace username
root
SURREAL_PASS
Root or namespace password
root
SURREAL_NS
Default namespace
test
SURREAL_DB
Default database
test
These map directly to the surreal sql CLI flags (--endpoint, --user, --pass, --ns, --db) and are recognized by official SurrealDB SDKs.
Core Capabilities
SurrealQL Mastery
Full coverage of the SurrealQL query language: CREATE, SELECT, UPDATE, UPSERT, DELETE, RELATE, INSERT, LIVE SELECT, DEFINE, REMOVE, INFO, subqueries, transactions, futures, and all built-in functions (array, crypto, duration, geo, math, meta, object, parse, rand, string, time, type, vector).
See: rules/surrealql.md
Multi-Model Data Modeling
Design schemas that leverage SurrealDB's multi-model capabilities -- document collections, graph edges, relational references, vector embeddings, time-series data, and geospatial coordinates -- all in a single database with a single query language.
See: rules/data-modeling.md
Graph Queries
First-class graph traversal without JOINs. RELATE creates typed edges between records. Traverse with -> (outgoing), <- (incoming), and <-> (bidirectional) operators. Filter, aggregate, and recurse at any depth.
See: rules/graph-queries.md
Vector Search
Built-in vector similarity search using HNSW and brute-force indexes. Define vector fields, create indexes with configurable distance metrics (cosine, euclidean, manhattan, minkowski), and query with vector::similarity::* functions. Build RAG pipelines and semantic search directly in SurrealQL.
See: rules/vector-search.md
Security and Permissions
Row-level security via DEFINE TABLE ... PERMISSIONS, namespace/database/record-level access control, DEFINE ACCESS for JWT/token-based auth, DEFINE USER for system users, and $auth/$session runtime variables for permission predicates.
See: rules/security.md
Deployment and Operations
Single-binary deployment, Docker, Kubernetes (Helm charts), storage engine selection (memory, RocksDB, SurrealKV, TiKV for distributed), backup/restore, monitoring, and production hardening.
See: rules/deployment.md
Performance Tuning
Index strategies (unique, search, vector HNSW, MTree), query optimization with EXPLAIN, connection pooling, storage engine trade-offs, batch operations, and resource limits.
See: rules/performance.md
SDK Integration
Official SDKs for JavaScript/TypeScript (Node.js, Deno, Bun, browser), Python, Go, Rust, Java, .NET, C, PHP, and Dart. Connection protocols (HTTP, WebSocket), authentication flows, live query subscriptions, and typed record handling.
See: rules/sdks.md
Surrealism WASM Extensions
New in SurrealDB 3: extend the database with custom functions, analyzers, and logic written in Rust and compiled to WASM. Define, deploy, and manage Surrealism modules.
See: rules/surrealism.md
Ecosystem Tools
Surrealist -- Official IDE and GUI for SurrealDB (schema designer, query editor, graph visualizer)
Surreal-Sync -- Change Data Capture (CDC) for migrations from other databases
SurrealFS -- AI agent filesystem built on SurrealDB
# Full diagnostic (Rich output on stderr, JSON on stdout)
uv run {baseDir}/scripts/doctor.py
# Quick check (exit code 0 = healthy, 1 = issues found)
uv run {baseDir}/scripts/doctor.py --check
# Check a specific endpoint
uv run {baseDir}/scripts/doctor.py --endpoint http://my-server:8000
The doctor script verifies: surreal CLI installed and on PATH, server reachable, authentication succeeds, namespace and database exist, version compatibility, and storage engine status.
Schema Introspection
# Full schema dump (all tables, fields, indexes, events, accesses)
uv run {baseDir}/scripts/schema.py introspect
# List tables with summary
uv run {baseDir}/scripts/schema.py tables
# Inspect a specific table
uv run {baseDir}/scripts/schema.py table <table_name>
# Export schema as SurrealQL (reproducible DEFINE statements)
uv run {baseDir}/scripts/schema.py export --format surql
# Export schema as JSON
uv run {baseDir}/scripts/schema.py export --format json
Introspection uses INFO FOR DB, INFO FOR TABLE, and INFO FOR NS to reconstruct the full schema.
# 1. Export v2 data
surreal export --endpoint http://old-server:8000 --user root --pass root \
--ns myapp --db production v2-backup.surql
# 2. Review breaking changes (see rules/surrealql.md v2->v3 migration section)# Key changes: range syntax 1..4 is now exclusive of end, new WASM extension system# 3. Import into v3
surreal import --endpoint http://localhost:8000 --user root --pass root \
--ns myapp --db production v2-backup.surql
# 4. Verify schema
uv run {baseDir}/scripts/schema.py introspect
Data Modeling for a New Domain
# 1. Read rules/data-modeling.md for schema design patterns# 2. Read rules/graph-queries.md if your domain has relationships# 3. Read rules/vector-search.md if you need semantic search# 4. Draft schema.surql with DEFINE TABLE, DEFINE FIELD, DEFINE INDEX# 5. Import and test
surreal import --endpoint http://localhost:8000 --user root --pass root \
--ns dev --db test schema.surql
uv run {baseDir}/scripts/schema.py introspect
Deploying to Production
# 1. Read rules/deployment.md for storage engine selection and hardening# 2. Read rules/security.md for access control setup# 3. Read rules/performance.md for index strategy# 4. Run doctor against production endpoint
uv run {baseDir}/scripts/doctor.py --endpoint https://prod-surreal:8000
# 5. Verify schema matches expectations
uv run {baseDir}/scripts/schema.py introspect --endpoint https://prod-surreal:8000
Upstream Source Check
# Check if upstream SurrealDB repos have changed since this skill was built
uv run {baseDir}/scripts/check_upstream.py
# JSON-only output for agents
uv run {baseDir}/scripts/check_upstream.py --json
# Only show repos that have new commits
uv run {baseDir}/scripts/check_upstream.py --stale
Compares current HEAD SHAs and release tags of all tracked repos against the
