What is Database Admin Free?
Database Admin Free is an Openclaw Skills package for handling foundational PostgreSQL administration tasks through an AI agent workflow. It focuses on the essentials: table design with primary keys, NOT NULL and DEFAULT constraints, common column types, single-row and batch inserts, basic SELECT queries, and transaction control.
This skill is designed for practical day-to-day database operations where speed and consistency matter more than advanced tuning. Openclaw Skills makes it easier to generate structured SQL, validate common database changes, and keep work aligned with a predictable input/output contract.
Database Admin Free Use Cases
- Designing a new PostgreSQL table for a small application or prototype
- Generating INSERT statements for single-row or multi-row data loading
- Running filtered, sorted, or grouped SELECT queries on structured data
- Wrapping write operations in BEGIN/COMMIT/ROLLBACK transactions
- Validating schema choices such as VARCHAR, INT, SERIAL, TIMESTAMP, and DECIMAL
- Supporting AI agent-driven database admin tasks with repeatable output
- Handling common inventory-style or record-keeping databases like stock_info
How Database Admin Free Works
- Receive an input request describing the database task, such as table creation, inserts, or query generation.
- Determine the required schema elements, including primary key strategy, nullable fields, defaults, and appropriate PostgreSQL data types.
- Produce SQL for CREATE TABLE, INSERT, SELECT, or transaction blocks based on the requested action.
- Execute or present the SQL in a structured workflow that supports batch operations and rollback-safe changes.
- Return the result in a predictable response format so the agent can verify execution and continue processing.
- Apply error-aware handling for common issues like duplicate keys, type mismatches, missing required values, or uncommitted transactions.
Database Admin Free Setup
- Ensure your AI agent runtime supports SKILL.md-based skills and PostgreSQL-oriented SQL generation.
- Configure the required LLM API key in your environment.
export API_KEY=${API_KEY:?Please set the environment variable}
- Restart the terminal session or agent session so the environment variable is available.
- Call the skill from the AI agent conversation and provide the required
inputplus optionaloptions. - If you are automating callbacks, provide
callback_urlfor asynchronous completion handling. - Verify the generated SQL output and apply it in your PostgreSQL workflow.
Supported environments mentioned by the skill include Claude Code, Cursor, Codex, Gemini CLI, Windows, macOS, and Linux.
Database Admin Free Data Schema & Taxonomy
The skill follows a simple request/response contract and uses PostgreSQL-flavored SQL as its primary data format.
Input fields
| Field | Type | Required | Purpose |
|---|---|---|---|
| input | string | Yes | The database admin task, command, or data payload to process |
| options | object | No | Additional configuration such as mode or formatting preferences |
| callback_url | string | No | Async callback endpoint after processing completes |
Core SQL patterns
| Area | Typical objects | Example constructs |
|---|---|---|
| Table design | schema definition | PRIMARY KEY, NOT NULL, DEFAULT, CREATE INDEX |
| Data types | PostgreSQL basic types | TEXT, VARCHAR(n), INT, SERIAL, TIMESTAMP, DECIMAL(p,s) |
| Inserts | single and batch writes | INSERT INTO ... VALUES ... inside BEGIN / COMMIT |
| Queries | read operations | WHERE, ORDER BY, GROUP BY |
| Transactions | write safety | BEGIN, COMMIT, ROLLBACK |
Output contract
The response is structured as JSON with:
success: boolean execution statusdata.result: the generated or processed resultdata.execution_time: runtime summarydata.metadata: version and processor identifiersexecution_log: ordered processing stepserror: null on success or an error object/message on failure
Metadata taxonomy
version: skill version identifierprocessor: logical processor name (database-admin)- SQL examples are centered around inventory-style tables such as
stock_info
