Every example on these pages is a complete one you can run right now — the whole gallery ships inside the binary: ```bash theme={"system"} nika examples run showcase/t1-meeting-actions --model mock/echo # offline · zero key ``` The YAML you read here is projected verbatim from [`nika-spec/examples/showcase/`](https://github.com/supernovae-st/nika-spec/tree/main/examples/showcase), where each file passes the same conformance gate as the spec's own test suite. If a file is on this page, it parses — and it runs. These {SHOWCASE.count} workflows ({SHOWCASE.t1} starters · {SHOWCASE.t2} chains · {SHOWCASE.t3} fan-outs · {SHOWCASE.t4} epics) plus the foundation set exercise **all {CANON.builtins} builtins**, the {CANON.verbs} verbs, and {CANON.providers} providers — cloud, local and mock. ## How to read a workflow diagram Tasks are colored by verb, the same palette everywhere in the Nika universe: ```mermaid theme={"system"} flowchart LR A["infer · call a model"]:::infer --> B["exec · run a process"]:::exec B --> C["invoke · call a tool"]:::invoke --> D["agent · drive a loop"]:::agent classDef infer fill:#5b8cff22,stroke:#5b8cff,color:#5b8cff classDef exec fill:#ff7a3c22,stroke:#ff7a3c,color:#ff7a3c classDef invoke fill:#22d3ee22,stroke:#22d3ee,color:#22d3ee classDef agent fill:#b07bff22,stroke:#b07bff,color:#b07bff ``` ## T1 · Starters Four tasks or fewer, one chain or one diamond. You can run one of these in your first five minutes. **Engineering** — your standup note, written from what you actually committed yesterday. **Every office** — transcript in, tracker-ready typed action items out. **E-commerce** — a price-drop alert with zero model calls. **Marketing** — one post becomes a thread, a LinkedIn post and a newsletter blurb, in parallel. ## T2 · Chains Four to six tasks. Structured outputs, human gates, and the data builtins start pulling their weight. **Engineering / DevRel** — git log → typed notes → CHANGELOG edited in place → team pinged. **SEO / Content** — a brief grounded in what your competitor actually published. **Finance / Freelance** — reminders drafted, and NOTHING goes out until a human says yes. **Customer support** — the overnight queue classified, first replies drafted, urgent ones escalated. **Legal** — clause extraction on a LOCAL model. The contract never leaves the machine. **Data engineering** — bad batches degrade to a quarantine file instead of killing the pipeline. **DevOps** — dependency feeds diffed against last run. Only the NEW ships reach you. ## T3 · Fan-out `for_each` over collections the workflow discovers at runtime, with retry, bounded parallelism and jq fan-ins. **Strategy / PMM** — everything they shipped last week, read in parallel, one Monday brief. **Product / i18n** — the whole docs tree translated, voice intact, zero copy-paste. **SRE / Platform** — only unsanctioned prod drift wakes anyone. jq decides; the model explains. **Engineering** — a read-only review agent per changed file. A swarm with a leash. **HR / Recruiting** — one local-model rubric per candidate, ranked deterministically. PII stays home. ## T4 · Epic Multi-stage pipelines: agents under budget, human gates, runs that report on themselves. **Research / VC** — plan → budgeted research agent → thinking-model synthesis. Auditable end to end. **SRE / On-call** — evidence in parallel, a typed timeline, and a recovery check before the draft. **Founders / Execs** — market + engineering + KPIs synthesized — and the ping tells you what the run cost. **DevOps / Release** — parallel gates, a human GO, a hold until the window. Time as a first-class citizen. ## Find the example that teaches X Looking for one construct?

reference is an edge** · `${{ tasks.X }}` anywhere requires `depends_on: [X]`. The DAG has no invisible edges. * **`mock/echo` by default** · files run with zero API keys wherever the job allows; real providers only where the job demands one; local models where the data is sensitive. * **Projection, not copy-paste** · these pages and the [nika.sh use-cases explorer](https://nika.sh/#use-cases) render the same files, projected by `showcase-projector.py`.
