Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00131 | $0.03012 |
| Opus 5 | $0.00066 | $0.01506 |
| Sonnet 5 | $0.00026 | $0.00602 |
| Haiku 4.5 | $0.00013 | $0.00301 |
Grade B, and why
bpmn-to-drawio scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

BPMN to Draw.io Converter
Overview
This skill converts BPMN 2.0 XML files into Draw.io native format (.drawio) using the bpmn2drawio Python tool. The tool provides:
- Automatic Graphviz-based layout for files without DI coordinates
- Four built-in themes with custom YAML branding support
- Visual markers for gateways (X, +, O) and task/event icons
- Complete swimlane support with proper hierarchy
- Model validation with error recovery
Conversion Workflow
Follow these steps in order. The workflow automatically handles dependency installation.
Step 1: Set Up Tool Path
The tool is bundled in the plugin's tools/bpmn2drawio/ directory. Use ${CLAUDE_PLUGIN_ROOT} for the plugin path (auto-set for marketplace-installed plugins):
# Use CLAUDE_PLUGIN_ROOT (auto-set for marketplace-installed plugins)
PLUGIN_DIR="${CLAUDE_PLUGIN_ROOT:-/path/to/plugins/bpmn-plugin}"
TOOL_SRC="$PLUGIN_DIR/tools/bpmn2drawio/src"
Step 2: Check and Install Python Dependencies
Check for required Python packages and install any that are missing:
# Check which packages are missing
python -c "import lxml" 2>/dev/null || echo "lxml: MISSING"
python -c "import networkx" 2>/dev/null || echo "networkx: MISSING"
python -c "import yaml" 2>/dev/null || echo "pyyaml: MISSING"
python -c "import pygraphviz" 2>/dev/null || echo "pygraphviz: MISSING (requires Graphviz)"
If any packages are missing (except pygraphviz), ask the user:
"The following Python packages are missing: [list]. Install them now with
pip install [packages]?"
If user approves:
pip install lxml networkx pyyaml
Note: pygraphviz is handled separately in Step 3 because it requires Graphviz.
Step 3: Check Graphviz and pygraphviz
The tool's default --layout auto resolves to preserve — using the file's own BPMN DI coordinates — only when every element in the file already has a position, and falls back to Graphviz-based layout otherwise. Graphviz is therefore not required for files with complete DI coordinates, but you can't know in advance which files those are, so check availability up front:
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

bpmn-to-drawio is a skill published in the GitHub repository davistroy/claude-marketplace (5 stars, last pushed 5d ago), licensed MIT. It adds 131 tokens to every session and 3,012 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
