cz-cli-inner

name	cz-cli-inner
description	Use when answering operational ClickZetta Studio or Lakehouse requests from inside a cz-cli-aware agent, including listing metadata, running SQL, managing tasks, checking runs, or operating datasource and AI Gateway resources.

cz-cli Inner

Use cz-cli proactively for ClickZetta operational requests. Do not ask for information that can be discovered with cz-cli commands.

Core Rules

• Use cz-cli from PATH for Lakehouse and Studio operations.
• Run cz-cli <command> --help when exact flags are unclear.
• Prefer --format json for machine-readable output and preserve ai_message guidance.
• Use --profile <name> when the user names an environment or profile.
• On NO_PROFILE, guide the user to run cz-cli setup.
• Stop after the same command fails twice or repeated minor variations make no progress; report what failed and change approach or ask for guidance.
• Never fabricate URLs, task IDs, run IDs, table names, or profile names. Use exact command output.

SQL Rules

• Current default SQL mode is sync: cz-cli sql "SELECT ..." waits for results.
• Use --async for large or long-running queries, then inspect with cz-cli sql status <job-id> or cz-cli job status <job-id>.
• Write operations always require --write, including DDL and DML.
• If SQL contains quotes, $, backticks, backslashes, or newlines, write it to a file and run cz-cli sql -f <file> to avoid shell corruption.
• Use ClickZetta Lakehouse SQL syntax only. Before generating, modifying, validating, explaining, or running non-trivial Lakehouse SQL, load the Lakehouse documentation skill if available.

Studio Task Rules

• Always pass --type when creating tasks.
• Flow tasks use cz-cli task flow * commands for nodes; do not use normal task content/deploy commands on flow nodes.
• Confirm intent before destructive or state-changing operations: deploy, undeploy, execute, delete, refill/backfill, stop, rerun, and similar actions.
• For historical reruns or backfills, use cz-cli runs refill <task> --from YYYY-MM-DD --to YYYY-MM-DD; this is under runs, not task.
• For output table JSON flags such as --output-tables, pass the JSON array as one shell argument, usually with single quotes.

Output Handling

• --format json: best for parsing.
• --format toon: line-per-field output, useful with grep or head.
• --format table, --format csv, --format pretty: human-readable.
• --field <name>: extracts one field as raw text.
• Paginated list commands usually return page 1; check ai_message for next-page hints.
