What this skill does


## Usage

All scripts can be executed using Node.js. Replace `<param_name>` and `<param_value>` with actual values.

**Bash:**
`node <skill_dir>/scripts/<script_name>.js '{"<param_name>": "<param_value>"}'`

**PowerShell:**
`node <skill_dir>/scripts/<script_name>.js '{\"<param_name>\": \"<param_value>\"}'`

Note: The scripts automatically load the environment variables from various .env files. Do not ask the user to set vars unless skill executions fails due to env var absence.


## Scripts


### database_overview

Fetches the current state of the PostgreSQL server, returning the version, whether it's a replica, uptime duration, maximum connection limit, number of current connections, number of active connections, and the percentage of connections in use.

### list_replication_slots

List key details for all PostgreSQL replication slots (e.g., type, database, active status) and calculates the size of the outstanding WAL that is being prevented from removal by the slot.



---

### list_roles

Lists all the user-created roles in the instance . It returns the role name, Object ID, the maximum number of concurrent connections the role can make, along with boolean indicators for: superuser status, privilege inheritance from member roles, ability to create roles, ability to create databases, ability to log in, replication privilege, and the ability to bypass row-level security, the password expiration timestamp, a list of direct members belonging to this role, and a list of other roles/groups that this role is a member of.

#### Parameters

| Name | Type | Description | Required | Default |
| :--- | :--- | :--- | :--- | :--- |
| role_name | string | Optional: a text to filter results by role name. The input is used within a LIKE clause. | No | `` |
| limit | integer | Optional: The maximum number of rows to return. Default is 10 | No | `50` |


---

### replication_stats

Lists each replica's process ID, user name, application name, backend_xmin (standby's xmin horizon reported by hot_standby_feedback), client IP address, connection state, and sync_state, along with lag sizes in bytes for sent_lag (primary to sent), write_lag (sent to written), flush_lag (written to flushed), replay_lag (flushed to replayed), and the overall total_lag (primary to replayed).

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

Backend & APIsscripts

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
