Problem

Part of prompt partials (#100897), after #102076. References work end to end through the API, but the editor gives no help: users must hand-type @@@prompt:...@@@ tags from memory, tags render as opaque text, and there is no way to see what a fetch will actually return.

Changes

  • The prompt editor gains an "Insert reference" button: a searchable picker lists every other prompt with one row per label (follows the label) and one for the latest version (pinned), and inserts the tag at the cursor.
  • Reference tags render as clickable chips ("References: guardrails @ production") under the content in both view and edit mode, linking to the referenced prompt, mirroring the existing variables row.
  • View mode gains a "Show resolved" toggle when the prompt has references: it fetches the assembled content from the get-by-name endpoint and shows exactly what an SDK receives, with an "Includes:" row naming the spliced versions.
  • One shared module mirrors the backend tag grammar (promptReferences.ts, comment points at the authoritative backend regex).
  • Mechanical: kea typegen updates in llmPromptLogic.ts.

How did you test this code?

  • Full frontend typecheck passes (after building the @posthog/quill and @posthog/hogvm workspace packages, which this worktree had never built; no errors in changed files).
  • Not yet verified visually: screenshots of the picker, chips, and resolved preview follow before this leaves draft.
  • No new Jest tests: the resolution behavior is covered by backend API tests in feat(prompts): resolve prompt references at fetch time #102076; the added frontend code is UI wiring over one loader and one reducer. Named untested path: the toggle firing the get-by-name fetch with the viewed version.
  • New PromptReferenceTags component ships with a story.

Docs update

None yet: posthog.com docs PR covers the editor flow together with the API, after the prompt-partials flag rollout.

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

Agent: Claude Code, Fable 5

  • PR 5 of 6 (record → validate → protect → resolve → editor → visibility).
  • The editing surface is a LemonTextArea, not Monaco, so "highlighting" is chip rendering rather than in-editor decorations, and insertion works through the textarea cursor.
  • The picker follows PromptLabelPicker's quill Combobox pattern, the in-scene precedent.
  • Post-open findings, all fixed: picker search server-side and key collision (Greptile), quill/Lemon split and button guard (Greptile), preview failure reset (Greptile), URL-version resolution (CodeRabbit), variables from displayed text (Graphite), empty-render story removed (CI), and per the stamphog gate the stale-preview class is closed structurally in 7ddacf8: preview state clears when any prompt load starts, the single entry point to different content, rather than on individual outcomes. Docs comment dismissed: no in-repo doc covers this surface; posthog.com PR follows the flag rollout.
  • Skills invoked: /writing-ui-components, /writing-kea-logics, /writing-user-facing-copy, /writing-tests, /writing-pr-descriptions, /reviewing-with-coderabbit.
  • CodeRabbit CLI signed out; opened without a local pass, matching the previous PRs.

⚠️ Comment density — 4% of added code lines are comments (14 of 388)

This section warns when comments are more than 3% of the code lines a PR adds, and alerts above 6%. Before agent-assisted PRs, the typical share was about 2%. Only full-line comments count. Docstrings, generated files, snapshots, migrations, and workflow files are left out.

Comments that restate the code, record how the change came about, or narrate the next line add noise for the next reader. Keep the comments that explain a reason the code cannot show, and remove the rest. See .agents/skills/writing-code-comments/SKILL.md for the house rules.

✅ Toolbar bundle — eager 2.35 MiB within budget

What the toolbar ships to customer pages, measured from the esbuild output (minified, post-tree-shake). The eager set is the entry plus everything statically imported from it — fetched before any feature runs; deferred chunks load lazily. The eager guardrail is 5.72 MiB. Each output file must also stay below 10 MB, where CloudFront stops compressing it. The module boundary is enforced separately by check-toolbar-graph.

📝 Walkthrough

Walkthrough

Adds frontend support for prompt references. The change defines reference parsing and tag construction, displays linked reference tags, and adds Storybook examples. A searchable control loads prompt options and inserts label or version tags into the editor. Prompt details can retrieve and display resolved prompt content, with loading and error state handling.

Priority: ⬇️ Low

Merge Risk: 🔵 Low · up to 5e46a

Version navigation can temporarily show resolved content from a previous prompt and hide references while a preview loads. Resetting preview state and rendering tags for the raw-text fallback should be addressed before merge.

Use distinct keys for label and version options.

A valid label such as v3 makes the label key at line 38 equal to the version key at line 44. The later Map.set replaces the label option, so the picker cannot insert that label tag.

Use a semantic unique key, or make the label and version item keys distinct.

715-723: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Prevent stale resolved content after a version switch.

loadPromptSuccess resets isShowingResolvedPreview but does not clear resolvedPreview. When preview is enabled for another version, kea-loaders 3.1.1 retains the previous result while loadResolvedPreview is pending. promptSceneComponents.tsx can therefore render v1 content for v2 until the request completes.

Associate resolvedPreview with the requested version, or render it only when resolvedPreview.version === values.prompt.version.

Render a distinct request-failure state.

When llmPromptsList rejects during the initial load, promptOptions remains empty and loading ends. InsertPromptReferenceButton then renders “No matching prompts,” which misrepresents the request failure as an empty result. Store the failure state and render an error with a retry action.

719-719: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use the URL-selected version for resolved preview requests. Back/forward navigation starts loadPrompt() while values.prompt still contains the previous version. The resolved-preview control has no promptLoading guard, and loadResolvedPreview() reads values.prompt.version, so it can request the previous version. Derive viewedVersion from getSelectedVersionFromUrl() instead.

604-605: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Clear resolved-preview state when navigation starts.

urlToAction dispatches loadPrompt for version navigation. The current reducers do not reset resolvedPreview or isShowingResolvedPreview on loadPrompt. The prompt remains unchanged until loadPromptSuccess, so the old resolved content can remain visible while the new version loads.

Reset both values on loadPrompt.

Proposed fix
 resolvedPreview: {
+    loadPrompt: () => null,
     loadPromptSuccess: () => null,
     setMode: () => null,
 },
 isShowingResolvedPreview: [
     false,
     {
+        loadPrompt: () => false,
         toggleResolvedPreview: (state: boolean) => !state,
         setMode: () => false,
         loadPromptSuccess: () => false,

101-103: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Reset resolved preview state when prompt loading starts.

Version navigation dispatches loadPrompt while the previous prompt remains in state. resolvedPreview and isShowingResolvedPreview do not reset on loadPrompt or loadPromptFailure. The previous version's resolved content can therefore remain visible while the new version loads or after loading fails.

When resolved-preview loading starts without resolved content, displayText falls back to raw text while PromptReferenceTags remains hidden because preview mode is active. Reset both preview values on prompt load and failure. Render PromptReferenceTags when resolvedText is null, not only when preview mode is inactive.

A CodeRabbit review on the current head flags a still-unaddressed functional bug: resolved-preview state (resolvedPreview/isShowingResolvedPreview) isn't reset when a new version starts loading or fails, so stale content from a previous version can render briefly during navigation. The diff confirms the reducers only clear on loadPromptSuccess/setMode, not on loadPrompt or loadPromptFailure, so this is a genuine unresolved concern rather than a stale complaint.

  • Author wrote 22% of the modified lines and has 308 merged PRs in these paths (familiarity MODERATE).
  • coderabbitai[bot] reviewed the current head.
  • Unaddressed current-head CodeRabbit comment on promptSceneComponents.tsx (~line 101-103) / llmPromptLogic.ts: resolvedPreview and isShowingResolvedPreview are not reset on loadPrompt or loadPromptFailure, so stale resolved content from a prior version can render during version navigation or after a failed resolve.
  • This is the third iteration of essentially the same stale-preview-state class of bug flagged across successive commits (d19d87f, 551cbe7, 18e48f0, current head) — earlier instances were fixed but a variant persists at head.

Approved.

Contained frontend feature (prompt reference picker, chip rendering, resolved-preview toggle) with no touch on auth, billing, data models, dependencies, or CI/deploy — outside risky territory, so my own read of the diff is sufficient. The stale-preview, key-collision, and stale-version bugs flagged across several CodeRabbit/Greptile review rounds are visibly fixed in the current diff (reducers reset on loadPrompt, distinct picker keys, URL-derived version), and no maintainer hold or unresolved substantive concern remains on the current head.

  • Author wrote 22% of the modified lines and has 308 merged PRs in these paths (familiarity MODERATE).
  • 👍 on the PR from greptile-apps[bot].
