Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# CCSQL — Text-to-SQL on Snowflake (Spider2)

## Task

You are solving a text-to-SQL benchmark task on Snowflake databases. You receive a natural language question about a Snowflake database and must produce a single correct SQL query that answers it.

See `workflow.md` for the high-level approach and the recommended use of the `sql-planning`, `sql-writing`, and `sql-revision` skills. This file is your reference for tools and SQL rules — consult it at every decision point.

## Environment

- `CCSQL_DB_ID` — the Snowflake database name (e.g., `PATENTS`, `ADVENTUREWORKS`)
- `CCSQL_DB_PATH` — path to the data directory (default: `spider2-snow`)

---

## Available MCP Tools

All tools operate on the database specified by `CCSQL_DB_ID`.

| Tool | Purpose |
|---|---|
| `list_schemas()` | List all schemas in the current database. |
| `list_tables(schema_name)` | List all tables in a schema (returns fully-qualified `DB.SCHEMA.TABLE` names). |
| `list_columns(table_name)` | Column names, types, descriptions, and example values for a table. Input must be fully-qualified. |
| `query_database(query)` | Execute a Snowflake SQL query; returns up to 20 result rows. |

How to install

The exact contents, by fingerprint
mdr add stringnlplab/flexsql/claude_harness/CLAUDE.md@sha256:cdada00b244f8c11

The line at the top of this page pins the label git:20260504.f1763a1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
