Why Schemap?

Modern AI coding agents (Claude Code, Cursor, GitHub Copilot, Codex) struggle with complex production databases.

Raw pg_dump SQL dumps waste 10,000+ tokens, introduce noisy system metadata, cause broken multi-table JOINs, and force LLMs to guess business relationships.

Schemap solves this. Schemap is a deterministic CLI compiler that extracts database schemas, computes AI Readiness Scores, and generates compressed, token-optimized context maps (database_context.md, CLAUDE.md, AGENTS.md).

• Token-optimized context: Run schemap benchmark against your own schema to measure the raw-vs-compiled token footprint.
• Local-first & deterministic: Schema extraction and compilation run locally by default. Optional --enrich uses the configured OpenAI API, and licensed CI/CD usage performs an online license check.
• Sub-2ms Compilation: Compiles 200+ table database schemas in under 3 milliseconds.
• Multi-Database Support: PostgreSQL, MySQL, Turso / libSQL, SQLite, and Oracle.

Benchmark: Raw SQL vs. Schemap Context

Compression varies by schema. Run schemap benchmark to measure the token footprint, relationship coverage, AI Readiness Score, and generation latency for your own database.

Metric	Raw SQL Dump	Schemap AI Context	Difference
Token Footprint	Full raw schema estimate	Compiled context	Measured per schema
Relationship Mapping	Implicit / Scattered	Explicit FK Graph	Instant JOIN Clarity
AI Readiness Score	Unmeasured	Diagnosed (e.g. 78/100)	Actionable Fix Roadmap
Agent Rule Files	None	CLAUDE.md & AGENTS.md	Native Agent Integration

Installation & Quick Start

Install Schemap globally as a developer CLI via pipx (recommended) or uv / pip:

pipx install schemap-tool

Alternative package managers:

• uv: uv tool install schemap-tool
• pip: pip install schemap-tool

1. Verify Installation

schemap --version
# Schemap 0.8.0

2. Initialize Configuration

Generate a lightweight schemap.yaml config file:

schemap init

For full boilerplate options (domain mappings, schema overrides):

schemap init --full

2. Run Database Health Diagnostic (schemap doctor)

Diagnose database readiness and identify missing foreign keys, undocumented tables, or ambiguous column names:

schemap doctor

Output:

==================================================
 Schemap AI Database Health Check
==================================================
  Connection:            Connected (39 tables)
  Relationships Analyzed: 26
--------------------------------------------------
  AI Readiness Score:
  [###########---------] 53/100

  Top Issues Identified:
  - [Priority 1 - Missing Documentation] 39 tables lack descriptions/comments (-20 pts)
  - [Priority 2 - Disconnected Entities] 20 tables have no foreign keys (-7 pts)
  - [Priority 3 - Ambiguous Naming] 44 unresolved abbreviations detected (-20 pts)
--------------------------------------------------
 Recommendation: Run `schemap context` to generate AI-ready database context.
==================================================

3. Compile AI Database Context (schemap context)

Compile database_context.md containing relationship maps, central tables, and standard SQL JOIN snippets:

schemap context

4. Generate Agent Instruction Files (schemap agents)

Generate CLAUDE.md and AGENTS.md rules for your workspace:

schemap agents

5. Benchmark Context Efficiency (schemap benchmark)

Measure real-time token compression and compilation speed:

schemap benchmark

Supported Databases

• PostgreSQL (postgresql://user:password@localhost:5432/my_db)
• Turso / Remote libSQL (libsql://...)
• Local SQLite (sqlite:///path/to/db.sqlite3)
• MySQL (mysql://user:password@localhost:3306/my_db)
• Oracle (oracle://user:password@localhost:1521/my_db)

CI/CD Integration & Licensing

Automate context map updates on every migration commit with GitHub Actions:

• Free Tier: Full local CLI for databases up to 100 tables, including inspection, scoring, context, diffs, benchmarks, and exports.
• Pro Tier: Unlimited tables, CI/CD GitHub Actions integration, and production workflow support.

License management

Activate a purchased license globally with the schemap activate command. Use schemap status --verify to check it against the license service, and schemap logout to remove global credentials. The CLI resolves command-line, environment, global, and legacy project configuration credentials in that order. CI/CD should provide SCHEMAP_LICENSE_KEY through the repository secret store.
