# Database Context Map (Compiled by Schemap)

✓ Path found (2 hops): users → orders → payments

SELECT * FROM users

JOIN payments ON orders.id = payments.order_id;

The Dangerous Kind of Wrong

Looks right. Breaks in production.

AI agents confidently generate SQL matching familiar naming patterns—missing the actual relationships and foreign keys in your database.

Plausible query, broken relationship

SELECT orders.id, users.email
FROM orders
JOIN users
  ON orders.customer_id = users.id;

The query looks reasonable. But your schema uses orders.account_id, not orders.customer_id. The query crashes.

Explicit relationship context & zero guessing

orders.account_id
      ↓
accounts.id
      ↓
users.account_id

Schemap compiles the exact foreign key graph and anti-hallucination rules into your workspace.

Relationships get buried

Foreign keys and multi-table join paths disappear inside massive 10,000-token DDL dumps.

Names are not business context

acct_id or owner_id have specific meanings that models guess wrong without explicit context.

Token waste inflates agent costs

Dumping raw DDL every turn in autonomous loops burns hundreds of thousands of tokens per PR.

Developer FAQ

A few practical answers.

What is Schemap and how does it work?

Schemap is a local-first developer CLI compiler. It extracts schema metadata from PostgreSQL, SQLite, MySQL, Turso, or Oracle databases, computes AI Readiness scores, resolves foreign key join paths, and compiles compressed context files (schemap_database_context.md, CLAUDE.md, AGENTS.md) to prevent AI coding agents from guessing schema structures.

How do I update Schemap to the latest version?

Run pipx upgrade schemap-tool (or uv tool upgrade schemap-tool / pip install --upgrade schemap-tool). You can verify your active CLI version anytime with schemap --version.

Does Schemap send my database data to an AI?

Not by default. Extraction and compilation run locally. Optional --enrich sends compressed schema metadata to the configured OpenAI API. Licensed CI/CD usage also performs an online license check.

Does Schemap replace my ORM?

No. Schemap creates context for agents and SQL workflows. Your ORM, migrations, and application remain the source of truth for runtime behavior.

Can I use it with Cursor, Claude Code, Codex, or Copilot?

Yes. Generate Markdown context, CLAUDE.md, AGENTS.md, JSON, MCP, or framework exports for the workflow your agent already reads.

Which databases are supported?

PostgreSQL, SQLite, MySQL, Turso/libSQL, and Oracle are supported by the current extractors.

Give your database a context layer

Your AI is only as good as the context you give it.

Make the relationships explicit before your agent starts writing SQL.
