Layer2 Research Visuals

Research Visuals Router

Use this skill only after the matching research workflow has completed authentication, subject resolution and evidence retrieval.

Presentation Priority

1. When a real tool result is already linked to and rendered by a negotiated MCP App, keep the interactive App as the primary view and add only a short text interpretation. Do not render the same evidence again with show_widget.
2. When the host does not render the linked App and WorkBuddy exposes both read_me and show_widget, use one compact Widget for the smallest useful visual.
3. Otherwise return the same normalized evidence as a compact table and text.

MCP App and Widget share returned values, dates, units, sentiment labels, radar dimensions and source semantics. Widget is a WorkBuddy adapter, not an independent data or product layer.

Use When

• 用户明确要求“画图、走势图、K线、收益对比、事件表现、图表、研报图片”。
• 已取得的时间序列、方向对比或事件窗口数据用图形能明显降低理解成本。
• 用户需要普通问答中的图表，而不是完整 HTML 报告、仪表盘或 Playbook 页面。

Do Not Use When

• 只有一个数值或几行短表，图表只会重复信息。
• 本轮认证未成功、主体未解析、时间窗口不清楚或证据不足。
• 用户要求个人持仓收益、仓位建议、价格预测、策略回测、买卖指令或收益承诺。
• 用户明确要求行业多空风向标或事件因子解读 HTML；分别使用 layer3-industry-windvane 或 layer3-event-interpretation，并由它们调用 layer2-html-research-playbook 共享渲染。

Progressive References

Load only the references needed for the request:

• references/common.md: WorkBuddy inline visual gate, Fallback first, rendering safety, color, accessibility and failure behavior.
• references/market-charts.md: daily candlestick/volume, close or metric trend, and event-window return charts.
• references/widget-svg-runtime.md: chart-family template router and shared payload boundary.
• references/widget-kline-runtime.md: dedicated K-line, moving-average, volume and hover-detail runtime.
• references/widget-trend-runtime.md: dedicated one/two-series trend runtime.
• references/widget-event-runtime.md: dedicated signed event-window runtime.
• references/widget-compare-runtime.md: dedicated column/grouped-column comparison runtime.
• references/widget-combo-runtime.md: dedicated line-column runtime with evidence-governed dual axes.
• references/widget-radar-runtime.md: dedicated radar runtime requiring aligned values and an explicit source scale.
• references/report-images.md: stable report-image eligibility, source verification, MCP image boundaries and no-fake-link fallback.

Workflow

1. Finish the original Layer 2 route and its required Layer 1 contract preflight. This skill does not call a business data source by itself.
2. Identify the smallest useful visual: candlestick/volume, line trend, event-return bars, grouped comparison, line-column combination, calibrated radar or eligible report image.
3. Normalize the evidence once and prepare the compact text/table representation first.
4. Load references/common.md, the chart-specific reference, references/widget-svg-runtime.md, and exactly one selected family template for numeric charts.
5. If no MCP App already renders this result and the WorkBuddy inline visual gate passes, serialize the normalized payload once and run the packaged scripts/render_widget.mjs relative to this Skill directory. Pass its show-widget JSON output to show_widget without editing or reconstructing widget_code.
6. If the renderer exits non-zero, the visual gate does not pass or display fails, return the prepared table and text. Never expose raw widget markup or renderer errors.
7. Add the evidence window, source type, missing-data boundary and four-part financial disclaimer.

Hard Boundaries

• The visual is a presentation layer, not a new source. It must not add, interpolate, repair or predict data.
• Source data must come from the current authenticated turn. Do not reuse prior-turn evidence after an authentication failure.
• A chart cannot be the only user-visible result; include a short interpretation and a readable fallback.
• Every user-visible financial visual remains AI-generated public-information research. 用户可见内容必须明确：AI 生成、仅基于公开信息整理、不构成投资建议、不构成个股推荐。
• Do not show API keys, raw MCP JSON, physical database names, internal document IDs, model scores, holdings or trade history.
• Report images follow references/report-images.md; normal chart data follows references/market-charts.md.
• Same Boat research-visual/1 is an optional visual-evidence contract. Route each supported entry by kind, status and chart_type; never make a second visual call for an ordinary text answer.
• fallback_only, unsupported versions and invalid alignment must use the returned fallback_table or source text. Do not coerce them into a Widget.
• WorkBuddy-only rendering instructions remain internal. Other clients receive the same evidence as a compact table and text.
• A Same Boat viewpoint list/detail rendered through ui://tongzhou-fin-research/viewpoints/v1 must not trigger a duplicate Widget. Use Widget only as the non-App host fallback or for a separate chart the user explicitly requested.
• Normal-answer rendering may execute only the packaged scripts/render_widget.mjs with one ephemeral normalized JSON input. Do not write ad hoc Python/Node renderers, compute SVG coordinates in the model, edit the renderer output, or retain temporary SVG/PNG/HTML artifacts.
