Generates fact-checked infographic posters by separating claim verification from image rendering. Claude plans the content, verifies every statistic against peer-reviewed sources via web search, gets user approval, and only then hands a locked prompt to a text-to-image model. Use this skill whenever the user asks for a poster, infographic, or data visualization that contains numeric claims, statistics, or cited studies — especially comparison ("versus") posters, which invite fabricated mirror-statistics. Trigger phrases include "make a poster about X", "create an infographic comparing X and Y", "generate a data visualization of...", "design a poster that shows...". Skip only for purely decorative images or when the user supplies pre-verified data and just needs layout help.

What this skill does


# Verified Infographic Generator

**Version:** 1.0

## Overview

This skill produces high-quality infographic posters where **fact-verification is done by Claude in text** and the text-to-image engine is invoked **only in the final rendering step**, after all content has been locked and approved.

It exists because one-shot text-to-image generation of fact-based infographics has a very high fabrication rate. In one observed session generating a poster about biophilic design, 8 of 10 numeric claims (80%) were unsupported by the cited sources, and 2 of 5 citations were fictional or misattributed. Once incorrect text is baked into pixels, it cannot be corrected without regenerating, and readers have no way to audit where the numbers came from.

## Core Principles

1. **Separate facts from pixels.** Never let the image model choose which numbers to display.
2. **Evidence before composition.** No visual layout work begins until every claim has a verified source.
3. **Bake nothing unverified.** Any unverified claim blocks the pipeline, is downgraded to qualitative language, or is replaced.
4. **Preserve an audit trail.** Every number and citation in the final image must be traceable to a specific source URL and quoted passage in a sidecar file.
5. **Break symmetry bias.** Two-column "versus" layouts must explicitly allow asymmetric content — missing data on one side is a first-class output, not something to fabricate around.

## When to Use

Use this skill when the user asks for:

- A poster, infographic, or data visualization containing numeric claims
- A comparison ("X vs. Y") graphic where percentages or study results appear
- An evidence-based summary poster citing research, studies, or data
- An Earth Day / science communication / educational poster with statistics

Do **NOT** use this skill for:

- Purely decorative images with no factual claims
- Diagrams where the user supplies pre-verified data and just needs a layout rendered
- Artistic posters, logos, or illustrations without numeric content
- Static diagrams of known objects (use `interactive-infographic-overlay` for annotated scientific illustrations)

## Prerequisites

- Web search access (for Phase 2 source discovery)
- A text-to-image model available in the final step (OpenAI Images 2.0, Gemini, DALL·E, etc.)
- A project output directory (default: `docs/posters/`) where the poster, verification report, and sidecar source file will be saved together

## Workflow

The skill runs in **8 phases**. Phases 1–6 are executed by Claude. Phase 7 is the one image-model call. Phase 8 is a Claude audit of the final render.

### Phase 1: Intake & Claim Planning

Gather from the user:

- **Topic** of the poster
- **Intended audience** (grade 9-12, general public, policy maker, etc.)
- **Format** (landscape/portrait, dimensions, style preference)
- **Comparison structure** if any (A vs. B, single-subject, timeline, etc.)
- **Known references** the user wants to incorporate

Produce a **Claim Plan** — a structured list of 5–10 factual claims the poster must make. For each claim, record:

- Subject (what it's about)
- Metric type (percentage, count, range, qualitative descriptor)
- Polarity (positive outcome, negative outcome, neutral)
- Desired prominence (hero number, supporting stat, footnote)

Flag any planned comparison that invites symmetry bias. Tell the user explicitly: **"The 'versus' side may end up with less data than the main side. We will not invent numbers to balance it."**

Save the claim plan to `docs/posters/<slug>/01-claim-plan.yaml` using the template in `references/claim-plan-template.yaml`.

### Phase 2: Source Discovery

For each claim in the plan:

1. Run **at least two independent web searches** with different query phrasings.
2. Collect candidate sources. For each, record: title, authors, year, publisher or journal, URL, and a quoted sentence that directly supports the claim.
3. Prefer, in order:
   - Peer-reviewed journal articles
   - Systematic reviews and meta-analyses
   - Government reports (EPA, NOAA, USGS, UK GBC, WHO, etc.)
   - Named institutional studies with authors
4. Reject:
   - Blog posts citing unnamed "studies"
   - Marketing pages and vendor whitepapers
   - Wikipedia as a sole source (can be a pointer to primary sources)
   - Statistics without a traceable primary paper
   - Social media posts as primary sources

### Phase 3: Verification & Classification

Classify each claim into one of four buckets:

| Bucket | Meaning | What happens in the poster |
|---|---|---|
| **VERIFIED** | Specific number matches a specific peer-reviewed paper with a quoted passage | Use the exact number |
| **DIRECTIONAL** | Effect direction is well-established but the exact number differs across studies | Use a range (e.g., "+6% to +15%") or best-supported single study |
| **QUALITATIVE-ONLY** | Effect is supported but not quantified reliably | Use words ("lower," "significant," "elevated") — no fake percentage |
| **REJECTED** | No credible source | Remove from the poster or replace with a VERIFIED claim on a related subject |

For every VERIFIED and DIRECTIONAL claim, store a citation record:

```yaml
- claim_id: wellbeing_increase
  value: "+15%"
  source: "Human Spaces / Interface (2015)"
  authors: "Cooper, C. et al."
  year: 2015
  url: "https://..."
  quote: "employees who work in environments with natural elements report a 15% higher level of well-being"
  classification: VERIFIED
```

Save the full **Verification Report** to `docs/posters/<slug>/02-verification-report.md` using the template in `references/verification-report-template.md`.

**Abort condition:** If more than 20% of planned claims are REJECTED, stop the pipeline and tell the user the topic may not support the original framing. Offer to reshape the poster around the VERIFIED claims that remain.

### Phase 4: User Checkpoint (MANDATORY)

Present the Verification Report to the user. Show:

- Every original claim and its verdict
- Which claims survived with exact numbers
- Which were softened to qualitative language
- Which were dropped entirely
- Any fabrication risks detected (e.g., a "vs." side with thin evidence)

Wait for explicit user approval before proceeding. The user may:

- Approve the final claim set as-is
- Request additional sources for a specific claim
- Reshape the poster (remove comparison, change topic, widen scope)
- Accept qualitative language in place of a missing percentage

**Do not proceed to layout or rendering without this approval.** This is the single most important safety checkpoint in the pipeline.

### Phase 5: Layout Specification

Draft a structured layout spec in YAML (use `references/layout-spec-template.yaml`). Every text element must reference a `source_id` from the verification report, or be marked as a non-factual design element (title, decorative label, caption).

Key layout constraints:

- **Asymmetric layouts are allowed.** If the comparison side has only 3 verified claims to the main side's 5, render 3 vs. 5 — do not invent filler.
- **Mark qualitative claims clearly.** Use descriptor words instead of fake percentages ("Elevated," "Reduced," "Significant").
- **Cite in-place where possible.** Small parenthetical "(Author, Year)" under each statistic, with a full source list at the bottom.
- **One source per statistic minimum.** If a claim has no `source_id`, it cannot appear in the layout.

Save to `docs/posters/<slug>/03-layout-spec.yaml`.

### Phase 6: Image Prompt Assembly

Programmatically compose the text-to-image prompt from the approved layout spec. **Never re-author numbers at this stage** — copy them verbatim from the spec.

The assembled prompt must include these explicit instructions to the image model:

```
Render the following exact text verbatim. Do not substitute any numbers,
paraphrase any labels, or invent additional statistics, rows, or citations.
All percentages, author names, years, and institution names must appear
exactly as written below. If you cann
