Add Svg

Add SVG Skill

Add SVG assets to draw.io research figures as evidence-aware visual elements, not decorative stickers. This skill follows the nature-figure and research-drawio-skill philosophy: establish the scientific message and visual role first, decide the SVG source explicitly, then integrate only assets that serve the diagram's logic and pass layout/export QA.

Mandatory Source Gate

Before doing any SVG search, drawing, download, file edit, or draw.io insertion, ask exactly one blocking question and stop:

SVG 来源选择：网络搜索，还是自行绘制？

Do this on every invocation. Continue only after the user answers. The answer sets source_mode:

• network / 网络搜索: search the web for multiple SVG candidates.
• self_design / 自行绘制: design new SVGs from vector primitives.

If the user already describes a preference in the same message, still confirm briefly before execution unless the conversation already contains an explicit answer to this exact source gate for the current invocation.

Routing Protocol

1. Read manifest.yaml.
2. Read every file listed under always_load:
   • static/core/contract.md
   • static/core/stance.md
3. Ask the mandatory source gate and wait for the user's answer.
4. Load the reference file for the chosen mode:
   • network search: references/network-svg-search.md
   • self design: references/self-design-svg.md
5. Load references/drawio-svg-integration.md before editing .drawio.
6. Load references/svg-qa-contract.md before final delivery.

Core Workflow

After the source gate is answered, create a compact SVG contract:

Scientific message:
Target draw.io file:
SVG role:
Source mode:
Needed concepts:
Candidate plan:
Integration targets:
Style constraints:
License/provenance notes:
Fallback plan:
QA checks:

Network Mode

Search for multiple SVG candidates for each requested concept. Keep candidates for later user selection rather than silently choosing one. For each candidate, record:

• concept
• preview/name
• source URL
• direct SVG URL if available
• license or usage note
• style fit for Nature-style draw.io figures
• any required attribution

If no suitable SVG is found for a concept, mark it as self-designed fallback and create a simple original SVG following references/self-design-svg.md.

Self-Design Mode

Create original SVGs from simple vector primitives. Keep them restrained, editable, and compatible with draw.io. Use one neutral family, one signal family, and one accent family. Avoid complex illustration, gradients, shadows, bitmap effects, and decorative detail.

Draw.io Integration Rules

• Preserve the user's existing .drawio content and layout.
• Insert SVGs as editable/vector-friendly draw.io image cells when possible.
• Encode SVG image values as draw.io-safe URL-encoded data:image/svg+xml, URIs. Do not use raw data:image/svg+xml;base64,... inside style=, because the semicolon in svg+xml;base64 breaks mxGraph style parsing.
• Treat an inserted SVG as the visual glyph for that concept. Do not also draw duplicate draw.io primitive glyphs for the same object unless the user asks for a hybrid editable reconstruction.
• After SVG insertion, re-balance the layout and remove empty placeholder zones so the figure remains compact rather than leaving the old self-drawn glyph space unused.
• Keep SVG labels separate from the icon body unless text is a scientific mark.
• Match the diagram's grid, spacing, color semantics, and connector rules.
• Run available QA checks and export a draw.io PNG/SVG preview when research-drawio-skill/scripts/export_drawio_preview.py is available. Do not treat XML validity as sufficient for SVG insertion; the exported preview must show the SVG assets rendered, nonblank, unclipped, and not overlapping labels.
