What this skill does


# Google Calendar Skill

## Overview
This skill provides a thin wrapper around the Google Calendar REST API. It lets you:
- **list** upcoming events (optionally filtered by time range or query)
- **add** a new event with title, start/end time, description, location, and attendees
- **update** an existing event by its ID
- **delete** an event by its ID

The skill is implemented in Python (`scripts/google_calendar.py`). It expects the following environment variables to be set (you can store them securely with `openclaw secret set`):
```
GOOGLE_CLIENT_ID=…
GOOGLE_CLIENT_SECRET=…
GOOGLE_REFRESH_TOKEN=…   # obtained after OAuth consent
GOOGLE_CALENDAR_ID=primary   # or the ID of a specific calendar
```
The first time you run the skill you may need to perform an OAuth flow to obtain a refresh token – see the **Setup** section below.

## Commands
```
google-calendar list [--from <ISO> --to <ISO> --max <N>]
google-calendar add   --title <title> [--start <ISO> --end <ISO>]
                     [--desc <description> --location <loc> --attendees <email1,email2>]
google-calendar update --event-id <id> [--title <title> ... other fields]
google-calendar delete --event-id <id>
```
All commands return a JSON payload printed to stdout. Errors are printed to stderr and cause a non‑zero exit code.

## Setup
1. **Create a Google Cloud project** and enable the *Google Calendar API*.
2. **Create OAuth credentials** (type *Desktop app*). Note the `client_id` and `client_secret`.
3. Run the helper script to obtain a refresh token:
   ```bash
   GOOGLE_CLIENT_ID=… GOOGLE_CLIENT_SECRET=… python3 -m google_calendar.auth
   ```
   It will open a browser (or print a URL you can open elsewhere) and ask you to grant access. After you approve, copy the `refresh_token` it prints.
4. Store the credentials securely:
   ```bash
   openclaw secret set GOOGLE_CLIENT_ID <value>
   openclaw secret set GOOGLE_CLIENT_SECRET <value>
   openclaw secret set GOOGLE_REFRESH_TOKEN <value>
   openclaw secret set GOOGLE_CALENDAR_ID primary   # optional
   ```
5. Install the required Python packages (once):
   ```bash
   pip install --user google-auth google-auth-oauthlib google-api-python-client
   ```

## How it works (brief)
The script loads the credentials from the environment, refreshes the access token using the refresh token, builds a `service = build('calendar', 'v3', credentials=creds)`, and then calls the appropriate API method.

**Note:** This skill does not require a GUI; it works entirely via HTTP calls, so it is suitable for headless servers.

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.
