v0.0.401

Version 0.0.401 (June 7, 2026)

• Agent run activity chart in /monitoring diagnosis — daily agent executions bucketed by status (success/error) with click-to-filter by day, backed by a new diagnosis timeseries endpoint
• Add a bagofwords MCP skill template documenting the core analysis workflow (create report, run tracked queries, build dashboards) for use with the BOW MCP connector
• MCP error handling: tool-level MCP failures (isError) now surface the server's real error message instead of None, so the agent can correct course instead of retrying blindly — and failed MCP calls no longer show a misleading green ✓ in the trace
• MCP planner context: the execute_mcp digest now echoes which underlying tool was called and with what arguments (plus the real error on failure), so the planner stops looping through call variants
• MCP tool UI: the tool card now shows the actual command/input invoked (tool + arguments for execute_mcp, query for search_mcps, code for write_csv), not just the result
