# 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:

1. Install via the Printing Press installer. It defaults binaries to `$HOME/.local/bin` on macOS/Linux and `%LOCALAPPDATA%\Programs\PrintingPress\bin` on Windows:
   ```bash
   npx -y @mvanhorn/printing-press-library install air-quality --cli-only
   ```
2. Verify: `air-quality-pp-cli --version`
3. Ensure the reported install directory is on `$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:

```bash
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:
