Configuration

Kraft's configuration is a set of YAML files under $KRAFT_HOME/config/ (default ~/.kraft/config/). This page maps each file to its reference page and says how the directory is created and edited.

Files

How Kraft treats the directory

• Seeding. Kraft copies the shipped defaults into config/ on first run and never overwrites it afterwards, so an upgrade cannot clobber an edited policy. Upgrade your configuration takes what a new release ships in library.yaml and chains/. The files marked "You" or "The first save in Settings" are never seeded.
• Editing. The Templates screens edit library.yaml and chains/. Settings edits the rest, except sandbox.yaml, detectors.yaml and harnesses/, which no screen edits. Editing any file by hand is equally supported.
• Moving it. KRAFT_HOME and KRAFT_CONFIG_DIR move the directory; see Environment variables.
• Validation. Kraft validates each file when it loads it, and reports a file that fails with the offending key named. Chain rules such as extends and reject_to are in Chain file keys.
• An old directory. Before 2.0, the directory was templates/; see Upgrade from 1.4. A home still in the 0.x template format (a registry.yaml, hook names or gate_after) is refused until you run kraft admin update; see Migrating a home from 0.x.

Three commands check and reload the files:

• kraft admin doctor reports anything that does not parse.
• kraft admin reload rereads policy.yaml, library.yaml with its chains, and intake.yaml without a restart. A change to access.yaml's bind or port needs a restart, and a hand edit of notify.yaml takes effect at the next save in Settings or a restart.
• kraft admin templates lint checks the whole library and every chain at once, and writes nothing.

In this section

• repos.yaml: every field in repos.yaml, and the pages for how connect proposes commands, detectors.yaml and workspaces.
• policy.yaml: every field in policy.yaml: caps, budget, concurrency, archiving, defaults and maxima.
• Library and chains: the sections of library.yaml, and how chains/*.yaml files compose them into chains.
• harnesses.yaml: every field in harnesses.yaml, for harness profiles and agent profiles.
• access.yaml: every field in access.yaml: bind address, port, password, session expiry and allowed hosts.
• intake.yaml: every field in intake.yaml: autonomous pickup from beads, and cron schedules.
• notify.yaml: every field in notify.yaml: the notification webhook and the events that post to it.
• theme.yaml: every field in theme.yaml: colors, density, the diff and the board.
• Sandboxed workers: the sandbox key of repos.yaml, and the pages for the container's resource limits, callbacks, network, credentials, Kits, sandbox.yaml and git.
• Environment variables: the variables that move this directory, every other variable Kraft reads, and the variables a worker gets.
