Visual Source Artifact

Visual Source Artifact

Use this skill when a human needs to inspect product, business, data, research, UX, or mockup work visually while agents need durable source they can diff, update, and verify.

Core Rule

Use a source-first pair:

• Canonical source: Markdown, TOON, JSON, YAML, specgraph-compatible docs, model text, or structured data.
• Generated review surface: static HTML, dashboard, state board, prototype, journey map, schema map, evidence board, or comparison page under generated/review/.
• For human-facing discovery and planning, the generated review surface should be infographic-style HTML under generated/review//.

Generated visual files are never the only durable source. Edit source first, then regenerate or discard the review surface.

Default Fidelity

• High-fidelity is the default for UI, product, customer-facing workflow, and mockup review.
• Low-fidelity sketches are scratch artifacts only unless the project explicitly records them as research evidence.
• Use realistic states, dense data, error paths, accessibility cues, assumptions, and evidence strength in the review surface.
• Use scan-friendly metrics, charts, timelines, evidence/freshness panels, and source links for non-UI human review artifacts.
• Use Mermaid for authored diagrams, Vega-Lite as the default chart grammar, Observable Plot for compact exploratory charts, D3 for bespoke static layouts, Graphviz for node-edge maps, ECharts only as generation-time/static output, RAWGraphs for exported design-led SVGs, and Chart.js only through server-rendered/static output or an equivalent static chart.
• Put chart and graph intent in artifact-infographic JSON fences or manifest infographics arrays when the project has the generic renderer.

Artifact Families

• Product: PRD, opportunity brief, feature map, roadmap, acceptance matrix.
• Business: business model, pricing assumptions, stakeholder map, operating risk, go-to-market assumptions.
• Data: schema, data dictionary, metric definition, lineage, quality rule, sample records.
• Research: claim-evidence matrix, literature theme map, interview synthesis, assumption register.
• UX: design brief, component state spec, interaction flow, high-fidelity prototype source, journey map.

Agent Team

• requirements-analyst owns product intent, requirements, and acceptance criteria.
• delivery-manager owns business viability, stakeholder impact, rollout, and risk.
• backend-engineer owns data shape, schemas, integrity, and metrics implementation constraints.
• research-writer owns citations, claim strength, research synthesis, and gaps.
• ux-researcher owns task evidence, prototype critique, high-fidelity UX review, and accessibility concerns.
• system-modeler owns UML/UWE/C4/workflow impact when structure or behavior changes.
• quality-reviewer owns freshness, manifest completeness, evidence sufficiency, and readiness risks.

Process

1. Name the decision the visual artifact supports.
2. Select the artifact family and owner agent.
3. Define the canonical source path under docs/artifacts/source// unless a domain docs path is better.
4. Define the generated review path under generated/review//.
5. List evidence links and label real evidence separately from synthetic user or agent-simulation evidence.
6. Add or update the manifest entry with source, review surface, owner, evidence, status, freshness, and reviewRequired: true when a generated HTML surface is expected.
7. Add artifact-infographic specs for charts, graphs, timelines, or source-backed infographic panels when useful.
8. Run node scripts/generate-artifact-review.mjs when available.
9. Run manifest and HTML policy checks before handoff when the project has them.
