KnowAir Forecast — Hourly & Daily Weather Forecasts
Query detailed hourly and daily weather forecasts for any location using the Caiyun Weather API.
Prerequisites
- A valid Caiyun Weather API token set as
CAIYUN_TOKENenvironment variable, or stored in~/.config/knowair/token. - Coordinates (longitude, latitude) for the target location.
Quick Start
python3 scripts/query_forecast.py --lng 116.3176 --lat 39.9760 --type daily --days 7
Workflow
- Resolve coordinates — convert city name to longitude and latitude if needed.
- Choose forecast type —
hourlyordaily. - Run the script:
python3 scripts/query_forecast.py --lng \x3CLNG> --lat \x3CLAT> --type \x3CTYPE> - Present results — highlight temperature ranges, precipitation probability, and notable weather changes.

Failure Handling
- Missing token → exit code 2 with setup instructions.
- API error → exit code 1 with error details.
- Network unreachable → suggest the user check connectivity.

Usage Guidance
This skill appears to be a straightforward Caiyun weather client. Before installing: 1) Confirm you trust the skill source (source/homepage are unknown). 2) Be aware it requires a Caiyun API token (CAIYUN_TOKEN); the script will also read ~/.config/knowair/token if the env var is not set—remove or secure any token file you don't want the skill to read. 3) The script makes network requests only to api.caiyunapp.com; if you need stronger isolation, run it in a sandbox. 4) If you expect automatic geocoding from city names, note the script requires explicit lng/lat (you or the agent must resolve names separately). If any of the above are unacceptable, do not install or provide your token.
Capability Analysis
Type: OpenClaw Skill
Name: knowair-air-quality
Version: 1.0.0
The skill is a standard implementation for querying weather forecasts from the Caiyun Weather API. The core logic in `scripts/query_forecast.py` uses Python's standard library to perform HTTP requests and handle API tokens via environment variables or a local configuration file (~/.config/knowair/token). No evidence of data exfiltration, malicious execution, or prompt injection was found.
Capability Assessment
Purpose & Capability
Name/description match the code and runtime instructions. The script implements hourly/daily forecasts using the Caiyun API and requires python3 and CAIYUN_TOKEN — both appropriate for this purpose. Note: the SKILL.md mentions resolving city names to coordinates but the included script requires explicit lng/lat inputs (geocoding is not implemented in the script). This is a minor documentation gap, not a functional mismatch.
Instruction Scope
Runtime instructions only direct running the included Python script and presenting forecast output. The script makes HTTP GET requests to https://api.caiyunapp.com and prints JSON results. It reads only the CAIYUN_TOKEN environment variable (with a local fallback file) and does not reference other system credentials, unusual files, or external endpoints. Network access is required and explicitly declared.
Install Mechanism
No install spec (instruction-only) and included code is small and straightforward. Nothing is downloaded from arbitrary URLs or installed from untrusted package sources. Risk from installation is low.
Credentials
The skill requires a single credential (CAIYUN_TOKEN), which is proportionate. However, the script falls back to reading ~/.config/knowair/token if the env var is absent; the registry metadata declared no required config paths, so this local-file access is not documented in the metadata. This is a minor inconsistency to be aware of.
Persistence & Privilege
The skill is not always-included and does not request elevated or persistent platform privileges. It does not modify other skills or system-wide settings. Autonomous invocation is enabled by default (normal for skills) but not elevated.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install knowair-air-quality - After installation, invoke the skill by name or use
/knowair-air-quality - Provide required inputs per the skill's parameter spec and get structured output
