Closes #163

The inspector record pane cannot show the standard record sidebar. itemEditor mode has no sidebar option.

Record chips now have an external-link action, and the agent has open_record_in_full_editor. Both open the normal DatoCMS record page in a new browser tab, which includes the standard sidebar and Web Previews. The chat stays in place. If the browser blocks the tab, the tool result includes the URL so the agent can share it.

Test plan

• npm test in dato-agent
• Click the external-link icon on a record chip and confirm the full record page opens
• Ask the agent for the standard sidebar and confirm it offers the full editor URL

Triage

Status: still relevant. Master has no way to reach the standard record sidebar from the Agent tab. setInspectorMode({ type: 'itemEditor' }) has no sidebar option, so a new tab is the right workaround.

Mergeability (head 641bd51):

• Based on current origin/master. GitHub reports MERGEABLE / CLEAN. No CI checks run on this PR.
• I ran npm ci, npm test (960/960 pass), npm run lint and npm run build in dato-agent. All pass.
• Trial merges with Fix Dato Agent sign-in: use oauth.datocms.com OAuth endpoints #157, Dato Agent: avoid Anthropic output-limit failures on large writes #160 and Dato Agent: redact credentials from copied failure diagnostics #161 apply cleanly. Fix Dato Agent sign-in: use oauth.datocms.com OAuth endpoints #157 and Dato Agent: redact credentials from copied failure diagnostics #161 also touch AgentFrame.test.tsx, but in other hunks.

Review

The approach matches the existing pattern in master: mentionHost.ts already opens about:blank during the click, nulls opener, then calls location.replace. The new projectUrl.ts helper also deduplicates mentionHost.ts's URL builder.

Findings, none blocking:

1. Agent-tool path is almost always a blocked popup. open_record_in_full_editor calls window.open after a model round-trip, with no user gesture. Most browsers block it. The fallback works: the tool returns the URL, and AgentFrame.tsx:3601 adds a record chip with the new external-link button. Consider making the chip the primary path and not attempting window.open from the tool.
2. Misleading activity label. activityLabels.ts:818 shows "Full editor ready" even when opened: false.
3. Silent failure on the chip button. AgentFrame.tsx:6130 ignores opened: false and swallows errors (for example a failed model lookup). The user gets no feedback.
4. Tool is also offered in the record sidebar. Both createInspectorNavigator and createSidebarNavigator implement it (navigation.ts:158, navigation.ts:221). In the sidebar the user is already on the full editor, so the tool only duplicates the tab. Consider exposing it only in the inspector.

Next step

1. Run the two unchecked manual test-plan items in a real project, in Chrome and Safari.
2. Optionally address findings 1-4.
3. Merge. It closes Dato Agent: no way to open the standard record sidebar from the Agent tab #163.
