Presets

Presets

Definition. A preset is one JSON file describing a stack: the commands to set up, run, lint, test and check; the layout (where backend, frontend, docs, contracts live); the path globs that scope rules; and the conventions for each language. It carries no code. That is what makes anycrew boilerplate-agnostic: your stack is a description, not a template you must adopt.

What the preset becomes

Field	Shows up in
commands	the command table in AGENTS.md, the constitution's quality bar, the spec loop
layout	the repository sketch in AGENTS.md and docs/13
rules.*_globs	the paths / globs / applyTo of generated rules
*_conventions	the 20-backend and 30-frontend rules and docs/13 section 4

Your own

Copy a shipped preset, change the fields, and run anycrew init --preset ./my-preset.json. A good preset's conventions are the ten sentences a senior engineer would tell a new hire on day one, not a style guide.
