Document zero-argument contract signatures#49
Merged
Conversation
Add an lspServers entry so the Claude Code plugin connects the allium-lsp language server to .allium files, giving Claude checker diagnostics, go-to-definition and hover immediately after each edit without a separate `allium check` invocation. Note in the README that allium-lsp is not bundled and must be installed separately (and be on PATH), consistent with official marketplace LSP plugins.

The language server calls createConnection(ProposedFeatures.all), which requires a transport flag on argv, so it must be launched as `allium-lsp --stdio` (per allium-tools CONTRIBUTING). Add args: ["--stdio"] to the lspServers entry; without it the server errors on startup. allium-lsp is not published to npm (the bare and @juxt-scoped names both 404), so drop the `npm install -g allium-lsp` instruction and point to the allium-tools repo for installing the server onto PATH instead.

Note that contract operations can take an empty parameter list, `name: () -> ReturnType`, for parameterless operations (list-all, fetch global state, health checks). Mirrors the v3 language reference in allium-tools and matches the parser fix in juxt/allium-tools#55. Refs #37 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

What
Documents that contract operations can take an empty parameter list —
name: () -> ReturnType— in the skill's language reference (contracts section).Why
Parameterless operations (list-all, fetch global state, health checks) are common at integration boundaries. This keeps the plugin's reference (which Claude reads when writing specs) in sync with the v3 language reference and the parser fix.
