Reference

Look-up surfaces. Nothing here teaches — these are the pages you come back to with a specific question.

Answering a specific question#

Question	Go to
Is this valid syntax?	Grammar — the full EBNF
Does target X support construct Y?	Target matrix — measured, per term
How does this keyword behave?	/corpus/, or `faber explain <term>`
What changed in this version?	Releases
Why is the language like this?	Design notes
Where does the source live?	Repositories

The fastest of these is usually the CLI:

faber explain redde
faber explain ⇥
faber targets

From the terminal#

faber explain reads the same corpus that generates these pages, so it will not drift from the site. faber targets prints the live capability notes for every backend — the same data the target matrix is built from.

Machine surfaces#

These are locale-less and live at the site root, not under /reference/:

Surface	Purpose
`/llms.txt`	index for models — start here
`/llms-full.txt`	expanded corpus frontmatter reference
`/agents/index.md`	learning path for agents
`/.well-known/agent-skills/`	focused skill guides

Pages here#

Page	What it is
Grammar	the full EBNF, rendered from the compiler's own specification
Releases	generated release inventory with assets and checksums
Design notes	the design laws, deferred features, and how the language got here
Repositories	the faberlang organization, repo by repo
