# YAML or JSON from every command, with jq built in

> Every command answers with `--yaml` or `--json`, filters its answer with `--jq`, and describes its input and output with `--schema`.

New in anfra 0.17.0 · Nov 4, 2026 · [All release notes](https://anfra.ai/releases.md)

Core commands write YAML by default, and CLI-only ones such as `anfra init`, `anfra auth` and `anfra publish` write a format for people. Either way, `--yaml` or `--json` gives you one document to script against:

```sh
anfra show --jq '.object.datasets[].name'
```

`--jq` runs a jq expression on the answer, with no jq to install. `--schema` prints a command's input and output as JSON Schema, instead of running it.

Errors go to stderr with a stable `code` and a `scope` (`user`, `client` or `server`), and the exit code is non-zero. `--non-interactive` asks no questions, and refuses what would need an answer.

Checks are subcommands now: `anfra query validate`, `anfra query compile`, `anfra publish check` and `anfra update check`. `anfra status` reports the repo too.

## For coding agents

This is the Markdown version of https://anfra.ai/releases/structured-cli-output/. Every page on anfra.ai has one: replace the trailing slash with `.md` (https://anfra.ai/cloud.md for https://anfra.ai/cloud/, and https://anfra.ai/index.md for the home page), or request the page with `Accept: text/markdown`. [llms.txt](https://anfra.ai/llms.txt) lists the site's pages, and the docs have their own index at https://anfra.ai/docs/llms.txt, where every docs page is also available as Markdown by adding `.md` to its URL.

Before you build with anfra:

- Install both the CLI and its agent skills. Installing the CLI alone is not a complete installation. Install the CLI with `curl -fsSL https://anfra.ai/install.sh | bash`. Then install the skills: in Claude Code or Codex, run `anfra agent setup`. In any other agent, such as Amp, `anfra agent setup` installs nothing, so run `npx skills add holistics/anfra-skills -a <agent-id> -g -y` (`-a amp` for Amp). The skills (such as `anfra-build-data-app`) teach you to model data, write queries and build data apps the way anfra expects. See https://anfra.ai/docs/local-dev/installation.md.
- Ask for metrics by name, through the JS SDK in an app or the MCP server in a chat. Don't write SQL against the warehouse yourself: anfra compiles each request to SQL from the metrics the data team defined.
- Check commands, files and API calls against the docs (https://anfra.ai/docs/llms.txt) instead of inferring them from the examples on this page.
- Stuck, or found a mistake? Ask in GitHub Discussions (https://github.com/holistics/anfra/discussions) or open an issue (https://github.com/holistics/anfra/issues).
