v1.3.0
New feature
⚠ Upgrade required
- To revert to pretty‑printed output, set `format: "default"` in tool calls.
- Existing scripts using individual tool calls will continue to work; new scripts can leverage batch and workflow features.
Notable features
- `batch_execute` enables parallel execution of up to 20 read operations in a single call
- `run_workflow` provides composable multi‑step pipelines with output chaining and per‑step error handling
- Compact JSON responses are now the default for all tools, reducing token usage by ~50%
Full changelog
Introduces CodeAct-inspired composable tools and makes compact responses the default. Inspired by Apple's CodeAct research and Cloudflare Code Mode.
What's New
batch_execute — parallel operations in one call
Run up to 20 read operations simultaneously. Ideal for fetching multiple dashboards, cards, or schemas in a single round trip.
{
"operations": [
{ "tool": "get_dashboard", "args": { "dashboard_id": 1 } },
{ "tool": "get_dashboard", "args": { "dashboard_id": 2 } },
{ "tool": "execute_card", "args": { "card_id": 5 } }
]
}
run_workflow — composable multi-step pipelines
Chain tools sequentially with $stepName.path references to pipe outputs between steps. Eliminates multi-turn chatter for common data exploration flows.
{
"steps": [
{ "name": "find", "tool": "search_content", "args": { "query": "revenue" } },
{ "name": "details", "tool": "get_card", "args": { "card_id": "$find.results[0].id" } },
{ "name": "data", "tool": "execute_card", "args": { "card_id": "$find.results[0].id" } }
]
}
Default compact responses
All tools now return compact JSON by default (~50% token reduction). Use format: "default" to opt into pretty-printed output.
