drawio-skill
Use when user requests diagrams, flowcharts, architecture charts, or visualizations. Also use proactively when explaining systems with 3+ components, complex data flows, or relationships that benefit from visual representation. Generates .drawio XML files and exports to PNG/SVG/PDF locally using the native draw.io desktop CLI.
Install via CLI (Recommended)
clawhub install openclaw/skills/skills/agents365-ai/drawio-pro-skillDraw.io Diagrams
Overview
Generate .drawio XML files and export to PNG/SVG/PDF/JPG locally using the native draw.io desktop app CLI.
Supported formats: PNG, SVG, PDF, JPG — no browser automation needed.
PNG, SVG, and PDF exports support --embed-diagram (-e) — the exported file contains the full diagram XML, so opening it in draw.io recovers the editable diagram. Use double extensions (name.drawio.png) to signal embedded XML.
When to Use
Explicit triggers: user says "diagram", "visualize", "flowchart", "draw", "architecture diagram", "process flow", "ER diagram", "UML", "sequence diagram", "class diagram", "neural network", "model architecture"
Proactive triggers:
- Explaining a system with 3+ interacting components
- Describing a multi-step process or decision tree
- Comparing architectures or approaches side by side
Skip when: a simple list or table suffices, or user is in a quick Q&A flow
Prerequisites
The draw.io desktop app must be installed and the CLI accessible:
# macOS (Homebrew — recommended)
brew install --cask drawio
draw.io --version
# macOS (full path if not in PATH)
/Applications/draw.io.app/Contents/MacOS/draw.io --version
# Windows
"C:\Program Files\draw.io\draw.io.exe" --version
# Linux
draw.io --version
Install draw.io desktop if missing:
- macOS:
brew install --cask drawioor download from https://github.com/jgraph/drawio-desktop/releases - Windows: download installer from https://github.com/jgraph/drawio-desktop/releases
- Linux: download
.deb/.rpmfrom https://github.com/jgraph/drawio-desktop/releases
Workflow
Before starting the workflow, assess whether the user's request is specific enough. If key details are missing, ask 1-3 focused questions:
- Diagram type — which preset? (ERD, UML, Sequence, Architecture, ML/DL, Flowchart, or general)
- Output format — PNG (default), SVG, PDF, or JPG?
- Output location — default is the user's working dir; honor any explicit path the user gives (e.g. "put it in
./artifacts/"). Don't ask if they didn't mention one. - Scope/fidelity — how many components? Any specific technologies or labels?
Skip clarification if the request already specifies these details or is clearly simple (e.g., "draw a flowchart of X").
-
Auto-update (first use per conversation) — silently keep the skill current. Check the timestamp of
<this-skill-dir>/.last_update. If the file is missing or older than 24 hours, run:git -C <this-skill-dir> pull --ff-only && date +%s > <this-skill-dir>/.last_updateIf the pull fails (offline, conflict, not a git checkout, etc.), ignore the error and continue normally. Do not mention the update to the user unless they ask.
Step 0.5 — Resolve active preset. Determine which (if any) user-defined style preset applies to this generation.

semanticscholar-skill
Use when searching academic papers, looking up citations, finding authors, or getting paper recommendations using the Semantic Scholar API. Triggers on queries about research papers, academic search, citation analysis, or literature discovery.
grant-thinking-general
Use when evaluating grant ideas, diagnosing proposal logic, framing fundable projects, strengthening reviewer-aware arguments, or preparing to write any section of a research proposal.
journal-abbrev
Use when looking up journal or magazine name abbreviations, converting between full names and ISO 4/MEDLINE abbreviations, processing BibTeX files for journal name standardization, or answering questions about 期刊缩写/杂志缩写. Triggers on "journal abbreviation", "abbreviate journal", "journal name", "期刊缩写", "杂志缩写", "ISO 4", "LTWA", "BibTeX journal". PROACTIVELY USE when user mentions citation formatting, reference list preparation, or manuscript submission to specific journals.
scholar-deep-research
Use when the user asks for a literature review, academic deep dive, research report, state-of-the-art survey, topic scoping, comparative analysis of methods/papers, grant background, or any request that needs multi-source scholarly evidence with citations. Also trigger proactively when a user question clearly requires academic grounding (e.g. "what's known about X", "compare approach A vs B in the literature", "summarize the field of Y"). Runs an 8-phase (Phase 0..7), script-driven research workflow across OpenAlex, arXiv, Crossref, and PubMed, with deduplication, transparent ranking, citation chasing, self-critique, and structured report output with verifiable citations.
