What changed and why

The AI chat renders charts, and there is a Save button meant to put one on a dashboard. It has never rendered. Not "rarely" — for no tool that exists.

The button sat inside a value.dashboard_url && (...) block that it shared with the "Open in dashboard" link. Those two controls answer different questions, and sharing a condition broke the button:

  • The four tools that produce a saveable ad-hoc chart (generate_report, get_funnel, get_rolling_active_users, preview_report_with_changes) all return through runReportFromConfig, whose return shape has no dashboard_url field. So the whole block was skipped and Save never rendered.
  • The one tool that does set dashboard_url, get_report_data, returns no report config, so it bails at the earlier !report || !report.chartType guard and never reaches the block at all.

This splits the condition. The link still requires dashboard_url, because it is a link to that URL. Save is now gated only on !report.id, which is the check that actually matters: it hides Save for a chart that is already a saved report. The container renders when either control has something to show, and Save carries ml-auto so it stays right-aligned when it is alone.

The change also passes the chart's title into the modal. Tools return the AI-generated title at the top level of the result, not inside the nested report object, so defaultValue={report.name} in the modal was pre-filling blank for every chat chart. Now it pre-fills what the chart is actually called.

One file, frontend only.

Evidence

  • apps/start/src/components/chat/tool-results/chat-report-result.tsx:86 — the single value.dashboard_url && block wrapping both controls; the !report.id check on the button is at :96.
  • packages/mcp/src/tools/analytics/reports.ts:311-352runReportFromConfig, the path taken by all four ad-hoc chart tools. Its declared return type at :322-329 is {chartType, interval, startDate, endDate, report, data}. No dashboard_url.
  • packages/mcp/src/tools/analytics/reports.ts:255-303runReport (get_report_data). Sets dashboard_url at :295, returns no report field, so it fails the guard at chat-report-result.tsx:57.
  • apps/api/src/agents/tools/base.ts:384 — the title is spread in as top-level name, alongside ...chart, rather than into the report object.
  • apps/start/src/modals/save-report.tsx:115defaultValue={report.name}, the field that was pre-filling blank.

No backend change is needed. report.create takes {report: zReport.omit({projectId: true}), dashboardId} (packages/trpc/src/routers/report.ts:34-40) and derives projectId from the dashboard row (:56). The only field in zReport without a default or optional marker is series (packages/validation/src/index.ts:243-245), and every chat config sets it. The modal already collects the two things a chat config lacks, name and dashboardId, and submits them itself (save-report.tsx:101-129).

Requested in

UserJot cmtmmqtc500yt0kpiaqkrtkfd, from Chris: "It seemed like it does it right in the chat, but I want it to create reports for me that I can insert into a dashboard."

Left out on purpose

  • get_report_data still renders no chart. It returns no report config, so it stops at the guard on line 57 and shows "Report data returned but no renderable config." That is a separate bug in a separate layer, and fixing it means changing the tool's return shape. Out of scope here. Worth its own issue.
  • dashboard_url on ad-hoc charts. Rather than make runReportFromConfig synthesize a URL, the link is simply gated on having one. Saving a chart is the thing that gets it a dashboard to link to.
  • Pre-existing lint in this file. biome check reports 17 diagnostics on this file (class ordering, JSX prop sorting, block statements) on the base commit and 17 after this change. I did not clean them up, to keep the diff readable. Only the Save button's own class string was reordered, because appending ml-auto would otherwise have added an 18th.

Checks

  • tsc --noEmit in apps/start: clean, 0 errors, after running pnpm db:codegen. Without the generated Prisma client the repo reports 318 errors; they are all @openpanel/db has no exported member cascades and unrelated to this change.
  • biome check on the changed file: 17 diagnostics, same count as base. No new lint debt.
  • pnpm vitest run could not run: it needs ClickHouse on 127.0.0.1:8123, which is not available in this environment. There are no tests covering chat/tool-results/ either way.

The behaviour itself is worth clicking through: generate a chart in chat, confirm Save appears, save it to a dashboard, and confirm a chart that is already a saved report shows no Save button.

Summary by CodeRabbit

  • Bug Fixes
    • Chat report actions now appear when a report can be saved, even if no dashboard link is available.
    • The “Open in dashboard” link only appears when a dashboard is configured.
    • The “Save” button is correctly shown for unsaved reports and aligned to the right.
    • Saving a report now preserves its existing details while applying the report name appropriately.

The Save button on chat chart cards has never rendered. It sat inside a
`value.dashboard_url &&` block along with the "Open in dashboard" link,
but every tool that produces a saveable ad-hoc chart returns through
runReportFromConfig, whose shape has no dashboard_url. The one tool that
does set dashboard_url, get_report_data, returns no report config and
bails at the earlier guard. So the button was unreachable for every tool
that exists.

The two controls answer different questions, so gate them separately:
the link needs a URL to point at, and Save only needs a chart that isn't
already a saved report.

Also pass the AI-generated title into the modal. Tools return it at the
top level of the result rather than inside the report object, so the
modal's name field was pre-filling blank.

Reported by a user who asked for chat charts he could put on a dashboard.

📝 Walkthrough

Walkthrough

The chat report footer now renders for unsaved reports without dashboard URLs. The dashboard link and Save button use separate conditions. The save modal receives the report fields with the resolved report name.

Changes

Chat report actions

Layer / File(s) Summary
Footer action rendering and save payload
apps/start/src/components/chat/tool-results/chat-report-result.tsx
The footer renders when a dashboard URL exists or the report has no ID. The dashboard link requires a dashboard URL. The Save button requires no report ID, aligns to the right, and passes the report fields with the resolved name to the modal.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to fe00c

Unsaved chat charts without an explicit generated name can open the save dialog with an incorrect or blank name instead of the displayed chart title. The save action is otherwise available as intended, but this prefill behavior should be corrected before merge.
