| Tool | Description | Behaviour |
|---|---|---|
| analyze_spintax | Reports 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. Answers "what variables must I supply" — it is NOT a variant-cardinality counter. | Read-only |
| render_spintax | Renders 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 validate_spintax first. | Read-only |
| spintax_authoring_guide | Read 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 it carries the agreement and case rules that decide whether the variants read as human writing, which is the hard part and the part a valid template can still get wrong; for ar, the six plural forms and their order. Returns text to read, not a template. | Read-only |
| validate_spintax | Static 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 some of them (plural.locale-missing) mean a block will not resolve. Pass knownVariables for names you will supply at render time to silence their variable.undefined warnings. | Read-only |
