Explores the schema (tables, columns, row counts) and writes a SQL state file so subsequent queries can restore this session automatically via duckdb -init. argument-hint <path-to-database.duckdb> allowed-tools Bash You are helping the user attach a DuckDB database file for interactive querying. Database path given: $0 Follow these steps in order, stopping and reporting clearly if any step fails. State file convention : see the \"Resolve state directory\" section below. All skills share a single state.sql file per project. Once resolved, any skill can use it with duckdb -init \"$STATE_DIR/state.sql\" -c \"<QUERY>\" . Step 1 — Resolve the database path If $0 is a relative path, resolve it against $PWD to get an absolute path ( RESOLVED_PATH ). RESOLVED_PATH= \" $(cd \" $(dirname \" $0 \" ) \" 2>/dev/null && pwd) / $(basename \" $0 \" ) \" Check the file exists: test -f \" $RESOLVED_PATH \" File exists -> continue to Step 2. File not found -> ask the user if they want to create a new empty database (DuckDB creates the file on first write). If yes, continue. If no, stop. Step 2 — Check DuckDB is installed command -v duckdb If not found, delegate to /duckdb-skills:install-duckdb and then continue. Step 3 — Validate the database duckdb \" $RESOLVED_PATH \" -c \"PRAGMA version;\" Success -> continue. Failure -> report the error clearly (e.g. corrupt file, not a DuckDB database) and stop. Step 4 — Explore the schema First, list all tables: duckdb \" $RESOLVED_PATH \" -csv -c \" SELECT table_name, estimated_size FROM duckdb_tables() ORDER BY table_name; \" If the database has no tables , note that it is empty and skip to Step 5. For each table discovered (up to 20), run: duckdb \" $RESOLVED_PATH \" -csv -c \" DESCRIBE <table_name>; SELECT count() AS row_count FROM <table_name>; \" Collect the column definitions and row counts for the summary. Step 5 — Resolve the state directory Check if a state file already exists in either location: # Option 1: in the project directory test -f .duckdb-skills/state.sql && STATE_DIR= \".duckdb-skills\" # Option 2: in the home directory, scoped by project root path PROJECT_ROOT= \" $(git rev-parse --show-toplevel 2>/dev/null || echo \" $PWD \" ) \" PROJECT_ID= \" $(echo \" $PROJECT_ROOT \" | tr '/' '-') \" test -f \" $HOME /.duckdb-skills/ $PROJECT_ID /state.sql\" && STATE_DIR= \" $HOME /.duckdb-skills/ $PROJECT_ID \" If neither exists , ask the user: Where would you like to store the DuckDB session state for this project? In the project directory ( .duckdb-skills/state.sql ) — colocated with the project, easy to find. You can choose to gitignore it. In your home directory ( ~/.duckdb-skills/<project-id>/state.sql ) — keeps the project directory clean. Based on their choice: Option 1: STATE_DIR= \".duckdb-skills\" mkdir -p \" $STATE_DIR \" Then ask: \"Would you like to gitignore .duckdb-skills/ ?\" If yes: echo '.duckdb-skills/' >> .gitignore Option 2: PROJECT_ROOT= \" $(git rev-parse --show-toplevel 2>/dev/null || echo \" $PWD \" ) \" PROJECT_ID= \" $(echo \" $PROJECT_ROOT \" | tr '/' '-') \" STATE_DIR= \" $HOME /.duckdb-skills/ $PROJECT_ID \" mkdir -p \" $STATE_DIR \" Step 6 — Append to the state file state.sql is a shared, accumulative init file used by all duckdb-skills. It may already contain macros, LOAD statements, secrets, or other ATTACH statements written by other skills. Never overwrite it — always check for duplicates and append. Derive the database alias from the filename without extension (e.g. my_data.duckdb → my_data ). Check if this ATTACH already exists: grep -q \"ATTACH.*RESOLVED_PATH\" \" $STATE_DIR /state.sql\" 2>/dev/null If not already present, append: cat >> \" $STATE_DIR /state.sql\" << 'STATESQL' ATTACH IF NOT EXISTS 'RESOLVED_PATH' AS my_data; USE my_data; STATESQL Replace RESOLVED_PATH and my_data with the actual values. If the alias would conflict with an existing one in the file, ask the user for a name. Step 7 — Verify the state file works duckdb -init \" $STATE_DIR /state.sql\" -c \"SHOW TABLES;\" If this fails, fix the state file and retry. Step 8 — Report Summarize for the user: Database path : the resolved absolute path Alias : the database alias used in the state file State file : the resolved STATE_DIR/state.sql path Tables : name, column count, row count for each table (or note the DB is empty) Confirm the database is now active for /duckdb-skills:query If the database is empty, suggest creating tables or importing data.",
