What it does
Pp Air Quality is an agent skill from mvanhorn/printing-press-library. Use OpenAQ and AirNow source-backed recipes for air-quality snapshots, nearby monitors, sensor history, point comparison, and AirNow AQI setup/current observations. Trigger phrases: air quality, OpenAQ, AirNow, AQI, PM2.5, nearby monitor, air-quality-pp-cli.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Official library of CLIs generated by the CLI Printing Press. Endorsed, tested, and community-contributed. The licence is Apache-2.0.
When your agent uses it
- Phrases: air quality
- Air-quality-pp-cli
Example prompts
- “/pp-air-quality”
Requirements
- Node.js
- A credential in AIR_QUALITY_OPENAQ_API_KEY
- A credential in AIR_QUALITY_AIRNOW_API_KEY
- Pre-approved tools (allowed-tools): Read, Bash
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and…
- Verify: air-quality-pp-cli --version
- Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.
What it can do on your machine
Read from SKILL.md and the folder at commit d9a1696. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadBash
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
gonpx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
AIR_QUALITY_AIRNOW_API_KEYAIR_QUALITY_OPENAQ_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Pp Air Quality loads about 1.1k tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 377 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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/binon macOS/Linux and%LOCALAPPDATA%\Programs\PrintingPress\binon Windows:bash npx -y @mvanhorn/printing-press-library install air-quality --cli-only - Verify:
air-quality-pp-cli --version - Ensure the reported install directory is on
$PATHfor 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@latestIf --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.
Show full SKILL.md (150 more words)Show less
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 --agentUse 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 --agentUse this when an agent needs candidate locations, sensors, and provider metadata.
Known OpenAQ Location
air-quality-pp-cli location 2178 --agentUse this when a workflow already has an OpenAQ location ID.
Sensor History
air-quality-pp-cli history --sensor 3917 --days 7 --agentUse 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 --agentUse 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 --agentUse this only when AIR_QUALITY_AIRNOW_API_KEY is configured.
Source Coverage
air-quality-pp-cli sources --agent
air-quality-pp-cli doctor --agentUse these before a larger workflow to confirm which source families are configured.
