Sandboxed WebAssembly plugins whose API is the command registry: - figcraft-plugin (new crate, L2): the figcraft-plugin.json manifest (menu commands with parameters, read/write access, command allowlist) and the sandbox: wasmi (pure Rust, no JIT, also in the web build) with fuel metering, a memory cap, no WASI and seven host functions (call, selection, reply_len, reply_read, log, notify, set_output). - Engine: plugin.list / plugin.import / plugin.remove / plugin.run, plugins.runLast (Alt+Cmd+P; Ctrl+Alt+Shift+P on Windows/Linux) and plugins.manage. A run is one undo step (Session::grouped, which command.batch now uses too) and is rolled back when it fails. Files, other documents, the undo history, dialogs and plugins are off limits; read-only plugins can't change the document. Installed plugins live in the preferences; development plugins re-read their module every run. - UI: installed plugins in the Plugins menu, a parameters form drawn from the manifest, Manage plugins, Plugins > Development > Import plugin from manifest. - plugins/: a no_std Rust SDK and two example plugins (Tidy names, Swatch grid), built for wasm32 by `cargo xtask plugins` (part of `cargo xtask wasm`). - Docs: docs/plugins.md (manifest, permissions, limits, ABI, SDK), docs/mcp.md, docs/control-protocol.md, README, ROADMAP, parity.
