# Features

Generated from the capability catalogue (`crates/engine/src/catalogue.rs`) by
`cargo run -p modelcraft-cli -- features > docs/features.md`; a test fails when it is out of date.
Every entry is a toolbar button. **Ready** entries run their command; **coming soon** entries are
shown greyed with the roadmap milestone that brings them (ROADMAP.md). Scripts, the command line,
the control channel and AI agents over MCP (docs/mcp.md) run the same commands.

52 ready, 51 coming soon.
