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.

What's Changed

• batch_execute tool — parallel execution of multiple read operations (#40)
• run_workflow tool — composable pipelines with output chaining and per-step error handling (#40)
• Compact responses by default — all 30 tools now use compact JSON (#40)
• 30 total tools (up from 28)
