Why Windsurf Needs Explicit Neon Schema Context
Windsurf is Codeium's agentic AI IDE. Like all LLM-powered coding tools, it has no native awareness of your database. Without explicit schema context, it will hallucinate JOIN paths, reference non-existent columns, query sensitive fields, and waste thousands of tokens per prompt.
Schemap solves this by extracting your live Neon schema and compiling it into .windsurfrules — a file Windsurf reads automatically from your project root.
Quickstart: Neon + Windsurf in 3 Steps
Step 1 — Install Schemap
pipx install schemap-tool
# or: uv tool install schemap-toolStep 2 — Connect to Neon
schemap quickstart
# Enter: postgresql://[user]:[password]@[endpoint].neon.tech/[dbname]?sslmode=requireStep 3 — Generate Windsurf database context rules
schemap agents --targets cursor
# Wrote .windsurfrules with safety guardrails in 2msWhat Schemap Injects into .windsurfrules
- Table Map — every Neon Postgres table with column types
- Foreign Key Graph — explicit JOIN relationships, no guessing
- Centrality Scores — most-connected tables highlighted
- [SAFETY] Guardrails — blocks sensitive column access and audit table mutation
- Candidate FK Detection — inferred missing relationships from naming patterns
Token Cost Savings on Neon Schemas
Raw Neon Postgres DDL dumps run 15,000–80,000 tokens. Schemap reduces that by 89%%. Run schemap benchmark --cost to calculate your exact monthly savings.

How do I give Windsurf Neon database context?
Install Schemap with pipx install schemap-tool, connect to your Neon Postgres database (postgresql://[user]:[password]@[endpoint].neon.tech/[dbname]?sslmode=require), then run schemap agents --targets cursor to auto-generate .windsurfrules with full schema context, foreign key maps, and anti-hallucination safety rules.
Does Schemap support Neon with Windsurf?
Yes. Schemap fully supports Neon (the serverless multi-tenant PostgreSQL cloud architecture) and generates native Windsurf database context rules that Windsurf reads automatically from your project directory.
What makes Schemap better than manually writing .windsurfrules for Neon Postgres?
Manual schema files go stale instantly. Schemap runs in sub-3ms, auto-infers foreign keys, injects SAFETY guardrails, and compresses your Neon Postgres schema by up to 89%% so Windsurf always has accurate context.
