# Authoring Nika workflows Nika turns repeatable AI work into files: one `.nika.yaml`, four verbs, audited **before** it runs. You author the file; `nika check` is the oracle; the human runs it. ## The loop (always) 1. **Start from a template or example**, never from scratch: `nika examples list` · `nika examples show <slug>` · `nika new --from <template> <file>.nika.yaml` 2. **Write the file.** Envelope is always `nika: v1` + `workflow: <kebab-id>` + `tasks:`. Pick models and builtins from the embedded catalogs — `nika catalog` (providers · models · capabilities · which env var each needs) and `nika catalog --tools` (the `nika:*` builtins an `invoke` reaches without MCP); before a run, `nika inspect <file>` shows the anatomy: tasks · waves · the cost floor. 3. **Check it**: `nika check <file>` (exit 0 = clean · 2 = findings), then `nika check --native-strict <file>` — it fails on any `native-first` hint (an `exec:` a builtin covers). 4. **Repair**: `nika check <file> --fix` applies the machine-applicable renames first (typo'd fields · tools · args · `after:` targets · `${{ }}` references — typed did-you-mean only, ambiguity is skipped with a note, never guessed) and re-audits; repair what remains from the diagnostics — they name the exact task, reference and fix. Unknown code? `nika explain NIKA-XXXX`. 5. Repeat 3–4 until clean. **Never hand a file to the human that does not pass `nika check`** — and pass `--native-strict` t
