Nika Skill

Use Nika as a deterministic workflow worker orchestrated by the Hermes terminal tool. Nika is an open-source (AGPL) Rust engine that captures a repeatable AI task as a plain-text *.nika.yaml file, audits it before a single token is spent (plan, cost floor, secret flows, types), executes it against local or cloud providers (Ollama/llama.cpp/vLLM included), and records a tamper-evident trace.

Division of labor: Hermes orchestrates · Nika captures repeatable work as a checkable file and runs it with receipts. Nika is NOT another coding agent — for autonomous coding, use the opencode skill. Delegate to Nika when the work should be repeatable, budgeted, and auditable.

When to Use

• The user asks to run, check, or author a *.nika.yaml workflow
• A task will be repeated (daily digest, triage, ETL, report, multi-step LLM

pipeline) — capture it as a workflow instead of re-prompting

• The user wants a hard cost cap, a cost estimate before running, or

receipts/audit of what ran

• A pipeline mixes models/providers (local + cloud) or mixes LLM steps with

shell/HTTP/file steps

• The user wants a run they can replay, verify, or reproduce later

When NOT to use

• One-off questions or single tool calls — just answer or use a tool
• Autonomous code implementation/refactoring/PR review — use the opencode skill
• Interactive ba
