Tools it offers

4 tools, as the server itself reported during our check on Oct 31, 2026.

• validate_spintaxStatic validation: returns diagnostics with severity, stable code, message and 1-based line/column. No "error"-severity diagnostic means the template is structurally sound — read the warnings before rendering, because so
• render_spintaxRenders up to 20 variants. With a seed the output is deterministic (variant i uses seed "<seed>#<i>"); without one it is random. The engine is lenient: structural mistakes never throw, they surface in the output — run va
• analyze_spintaxReports what the template needs and contains: refs (variables referenced), sets (#set macros, re-picked per reference), defs (#def, rolled once per render), includes, diagnostics, and best-effort construct counts. Answer
• spintax_authoring_guideRead this BEFORE writing or editing a spintax template — it is the canonical authoring guide the whole spintax toolchain is written against, not a tutorial. Pass the locale you will author in: for ru/uk/be and sr/hr/bs i
