# anchor_tasks_web — Dataset

A web-app generation benchmark. Each **task** is a multi-page UI taken from a public Figma community file. For every task we ship the textual page descriptions, the rendered mockup PNGs, the Figma node structure, the per-page click-annotations, and the distilled `data-testid` "anchors" that an evaluator uses to score a generated app.

The dataset is delivered in two layers:

1. **Ground-truth layer** — one folder per task (`1_newsletter/`, `2_real-estate/`, ...) holding *all* assets for that task.
2. **Input bundles** — one folder per **condition** (`c0/`, `c1/`, `c2/`, `c3/`) holding the strict subset of files that the generation agent receives, paired with a system-prompt file (`agent_system_promt_c{N}.md`).

`metadata.jsonl` describes both layers.

## Ground-truth assets (per task)

| File / Dir | What it is |
|------------|------------|
| `description.md` | The agent-facing brief. One section per page; every UI element that the eval scores carries an inline `<testid>` marker (kebab-case, between angle brackets). |
| `manifest.json` | `[{ index, page_name, file_key, node_id, png, structure_json, figma_meta }, ...]`. Maps page number → Figma frame. |
| `sitemap.md` | Auto-generated navigation graph derived from `interaction/*.json` (only annotations whose `type` is `navigate`). |
| `pages/<NN>_<Name>.png` | Rendered Figma frame for the page (the visual ground truth). |
| `pages/<NN>_<Name>.json` | Full Figma node tree for the page. |
| `pages/<NN>_<Name>_structure-only.json` | Pruned node tree (hierarchy + bbox + type, no styles/text content). Cheap input for c3. |
| `interaction/<page>_human_interaction_annotation.json` | Per-page list of human-tagged clickable elements: `{ id, type, interactable, navigateTo, node, bbox_png, subtype, reasoning }`. |
| `interaction/<page>_click_subtype.json` | Aggregate counts of click subtypes (`click_dead`, `click_popout`, `click_navigate`, ...). |
| `interaction/<page>_click_subtype_report.html` | QA visualization of the above. |
| `<task>_anchors.raw.json` | All annotations promoted to candidate anchors. |
| `<task>_anchors.json` | Filtered anchors. |
| `<task>_anchors.cleaned.json` | Final anchors used by the evaluator: `{ ann_id, testid, reasoning, bbox_png }` per page. |
| `interaction_index.json` (some tasks) | Top-level index of interaction files. |
| `interaction_index.verified.json` (some tasks) | Same, verified against the manifest. |

### Testid contract

The evaluator locates each scored anchor with `document.querySelector('[data-testid="<value>"]')`. Marker syntax in `description.md` is **`<value>`**, not `<testid>value</testid>` — angle brackets wrap the literal value. Examples: `<google>` → `data-testid="google"`; `<last-name>` → `data-testid="last-name"`. The cleaned anchors JSON pairs each testid with the bbox in PNG coordinates that the eval matches against.

## Conditions (input bundles)

| ID | What the agent sees | Bootstrap | System prompt |
|----|---------------------|-----------|---------------|
| `c0` | `description.md` only (no PNG, no Figma JSON) | hand-write everything | `agent_system_promt_c0.md` |
| `c1` | `description.md` + `pages/*.png` + `scaffold/` + `workspace/` | start from a pre-installed scaffold; **3 framework picks** under `c1/pick_{A,B,C}/`: A=Astro, B=Eleventy, C=Next.js 16 + React 19 + Tailwind v4 | `agent_system_promt_c1.md` |
| `c2` | `description.md` + `pages/*.png` | hand-write everything | `agent_system_promt_c2.md` |
| `c3` | `description.md` + `pages/*.png` + `pages/*_structure-only.json` | run an idiomatic scaffold yourself | `agent_system_promt_c3.md` |
| `c4` | same files as `c3` *(no separate `c4/` bundle is shipped — reuse `c3/<task>/`)* | hand-write from scratch (no scaffold artifact allowed) | `agent_system_promt_c4.md` |

### Why the conditions exist

The conditions form a 2×2×scaffold sweep over visual fidelity inputs vs. starter code:

- **Visual input axis**: text-only (c0) → text + PNG (c1, c2) → text + PNG + Figma structure JSON (c3, c4).
- **Bootstrap axis**: pre-installed scaffold provided (c1) vs. agent picks/runs scaffold (c3) vs. no scaffold allowed / hand-write (c0, c2, c4).
- **c1's three picks** isolate framework-choice variance under otherwise-identical inputs.

Sample count: `c0(10) + c1(10×3) + c2(10) + c3(10) = 60` input bundles. (`c4` reuses `c3` inputs and only swaps the system prompt, so it adds 10 more agent runs but no new files on disk.)

## metadata.jsonl

One JSON object per line; mixed `kind` field. Top-to-bottom order: dataset header (1) → task records (10) → sample records (60).

### `kind: "dataset"`
Header with name, conditions list, and the system-prompt files that pair with each condition.

### `kind: "task"`
One per ground-truth task folder.

```jsonc
{
  "kind": "task",
  "task_id": "1_newsletter",
  "task_index": 1,
  "task_title": "Task 1 — Newsletter / Blog Publication",
  "brand": "*BlogSprout* — a multi-author lifestyle/travel blog",
  "real_world_analogues": "Substack, Beehiiv, Medium",
  "figma_source": "Blog Sprout UI — FREE Figma Blog Web UI Kit and Design System (community)",
  "figma_file_key": "ymUMepRI8Lkg3TlPp5gqw0",
  "num_pages": 9,
  "pages_declared": 9,
  "page_files": ["01_Home.png", "02_Single-post.png", ...],
  "num_interactions_annotated": 9,
  "ground_truth_root": "1_newsletter",
  "anchor_files": ["1_newsletter_anchors.cleaned.json", "1_newsletter_anchors.json", "1_newsletter_anchors.raw.json"],
  "has_sitemap": true,
  "has_interaction_index": false
}
```

### `kind: "sample"`
One per (condition × task[ × pick]).

```jsonc
{
  "kind": "sample",
  "id": "c1/pick_A/1_newsletter",
  "condition": "c1",
  "pick": "A",
  "framework_pick_description": "Astro (with @astrojs/mdx, @astrojs/sitemap, @astrojs/rss).",
  "task_id": "1_newsletter",
  "task_index": 1,
  "task_title": "Task 1 — Newsletter / Blog Publication",
  "num_pages": 9,
  "agent_system_prompt": "agent_system_promt_c1.md",
  "input_root": "c1/pick_A/1_newsletter",
  "inputs": ["description.md", "pages/*.png", "scaffold/", "workspace/"],
  "ground_truth_root": "1_newsletter"
}
```

`input_root` is what the agent should be given as the project root. `ground_truth_root` is the canonical task folder used for evaluation only — never expose it to the agent.

## Quick recipes

**Iterate over all c1/pick_A samples:**

```bash
python3 - <<'PY'
import json
for line in open("metadata.jsonl"):
    r = json.loads(line)
    if r.get("kind") == "sample" and r["condition"] == "c1" and r.get("pick") == "A":
        print(r["id"], "→", r["input_root"])
PY
```

**Diff expected vs. actual testids for a generated app (matches the system-prompt verification step):**

```bash
TASK=1_newsletter
APP_DIR=/path/to/generated/app
grep -roE '<[a-z][a-z0-9_-]+>' "$TASK/description.md" | sed -E 's/.*<([^>]+)>.*/\1/' | sort -u > /tmp/expected
grep -roE 'data-testid="[a-z][a-z0-9_-]*"' "$APP_DIR" | sed -E 's/.*"([^"]+)".*/\1/' | sort -u > /tmp/actual
diff /tmp/expected /tmp/actual
```

**Pull the cleaned anchors for evaluation:**

```bash
jq '.anchors["01_Home"]' 1_newsletter/1_newsletter_anchors.cleaned.json
```

## Notes / gotchas

- `pages_declared` (from the description's `**Pages:** N` header) can disagree with `num_pages` (count of PNGs on disk) when the description groups several mockups under one logical page (e.g. settings tabs in `10_streaming_music-streaming`).
- `manifest.json` may contain entries with empty `file_key` / `node_id` for pages whose Figma annotation file was missing at extraction time (see the `_note` field on those entries). The PNG and structure JSON are still present.
- `pages/*.json` is the full Figma node tree; `pages/*_structure-only.json` is the pruned version. Only the latter is shipped in `c3/` to keep input size manageable.
- `c1/<pick>/<task>/scaffold/` and `c1/<pick>/<task>/workspace/` start as identical copies. `scaffold/` is read-only reference; the agent edits `workspace/`.
