How do I install the Pp Air Quality skill?

Run npx skillmds add mvanhorn-printing-press-libra/pp-air-quality in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is Pp Air Quality safe to use?

This skill has not completed SkillMD's automated safety review yet. Capability flags: makes network calls. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Air Quality - Printing Press CLI

Prerequisites: Install the CLI

This skill drives the air-quality-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:
```
npx -y @mvanhorn/printing-press-library install air-quality --cli-only
```
Verify: air-quality-pp-cli --version
Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead:

go install github.com/mvanhorn/printing-press-library/library/other/air-quality/cmd/air-quality-pp-cli@latest

If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.

Security note: this module declares toolchain go1.26.4 so environments with Go toolchain auto-download disabled should install Go 1.26.5 or newer before using the direct go install fallback.

When To Use

Use air-quality-pp-cli when an agent needs source-backed air-quality context:

Find nearby OpenAQ monitoring locations.
Fetch latest OpenAQ physical pollutant measurements near coordinates.
Fetch latest measurements for a known OpenAQ location.
Fetch a bounded recent measurement window for one OpenAQ sensor.
Compare two coordinate pairs using nearest OpenAQ snapshots.
Use AirNow current AQI observations by ZIP when an AirNow API key is configured.

When Not To Use

Do not use it for medical advice, emergency guidance, or regulatory decisions.
Do not convert OpenAQ physical measurements into AQI.
Do not use web-service commands for broad AirNow database population.

Setup

OpenAQ live commands require:

export AIR_QUALITY_OPENAQ_API_KEY="..."

AirNow commands require:

export AIR_QUALITY_AIRNOW_API_KEY="..."

Recipes

Current OpenAQ Snapshot

air-quality-pp-cli current --lat 40.7128 --lon -74.0060 --agent

Use this to find the nearest OpenAQ location and latest physical pollutant measurements.

Nearby OpenAQ Locations

air-quality-pp-cli nearest --lat 40.7128 --lon -74.0060 --agent

Use this when an agent needs candidate locations, sensors, and provider metadata.

Known OpenAQ Location

air-quality-pp-cli location 2178 --agent

Use this when a workflow already has an OpenAQ location ID.

Sensor History

air-quality-pp-cli history --sensor 3917 --days 7 --agent

Use this for a bounded recent measurement window. The CLI caps the window at 31 days.

Compare Two Points

air-quality-pp-cli compare --lat-a 40.7128 --lon-a -74.0060 --lat-b 34.0522 --lon-b -118.2437 --agent

Use this for source-backed comparison prose. Treat it as a snapshot, not exposure or health guidance.

AirNow Current AQI

air-quality-pp-cli airnow current --zip 10001 --agent

Use this only when AIR_QUALITY_AIRNOW_API_KEY is configured.

Source Coverage

air-quality-pp-cli sources --agent
air-quality-pp-cli doctor --agent

Use these before a larger workflow to confirm which source families are configured.
