Workflow templates

Compose new Arka tasks from reusable prompts and loops.

arka template list
arka template show research_brief
arka template use research_brief --set topic="local LLM serving"
arka template use repo_release

Templates are inspectable text, not hidden agent behavior. Prompt templates produce a prompt; loop templates produce a command you can review and run. Create a new workflow by copying a template output into arka iterate,

Code starters are also available for fast, distinctive scripts:

arka template list
arka template use python_cli --set description="CSV inspector" --out tools/inspect.py
arka template use api_health_check --set url="https://example.com/health" --out tools/health.py
arka template use data_pipeline --out tools/normalize.py
arka template use browser_smoke --out tests/smoke.py
arka template use walk_folder --set pattern="*.py" --out tools/list_python.py

--out refuses to overwrite an existing file. Templates are intentionally small and inspectable so Arka can customize them without hiding generated logic.

The walk_folder starter handles one folder by default and includes nested folders with --recursive:

python tools/list_python.py src --recursive --pattern "*.py"

Automatic prompt optimization

Arka automatically applies a local, deterministic pass to natural-language requests sent to AI routing. It clarifies the objective and expected output without inventing URLs, files, requirements, or facts. Symbolic routing keeps the original text, and code blocks, JSON, shell commands, and URLs are left unchanged. Use arka llm route "..." --skills "..." --no-optimize when exact prompt text must be preserved, or set ARKA_PROMPT_OPTIMIZE=0 globally.

Screenshots captured by web_screenshot and browser_check are temporary by default and cleaned up when the command exits. Pass --output when a review artifact must be retained for later inspection. arka loop, or another skill.
