Run from this skill directory, or replace scripts/ with the absolute path to
this skill's scripts directory:
python3 scripts/diagramctl.py doctor
python3 scripts/diagramctl.py build model.json --from ir -o architecture.drawio
python3 scripts/diagramctl.py build ./infra --from terraform --group \
--ir-output architecture.ir.json -o architecture.drawio
python3 scripts/diagramctl.py sync architecture.drawio ./infra --from terraform \
-o architecture.next.drawio

python3 scripts/diagramctl.py test architecture.drawio --rules policy.yml
python3 scripts/diagramctl.py review architecture.drawio -o review.md
python3 scripts/diagramctl.py query architecture.drawio --from internet --to orders-db
python3 scripts/diagramctl.py whatif architecture.ir.json --fail kafka \
--drawio kafka-failure.drawio -o impact.json
python3 scripts/diagramctl.py story architecture.ir.json -o walkthrough.html
doctor does not launch GUI tools unless --probe is passed. Core semantic
commands are offline and stdlib-only.
Infer the diagram type, audience, scope, output format, and location from the
request. Ask only when a missing choice materially changes the result;
default to PNG plus .drawio in the working directory.
Select the authoring route from the table above. For a data-backed diagram,
prefer Diagram IR and preserve provenance. For a large graph, use an importer
or autolayout.py; do not hand-place more than roughly fifteen nodes.
Resolve an explicitly named style preset, or the user's default preset, as
documented in references/style-presets.md. Structural diagram conventions
and visual presets compose; they do not replace each other.
Generate the .drawio, then run structural validation:
python3 scripts/validate.py diagram.drawio --score
When semantic metadata or an architecture policy is in scope, also run
diagramctl.py test. Do not present inferred semantic findings as verified
runtime facts.
Export a draft PNG without embedded XML and inspect it visually. Fix obvious
overlap, clipping, disconnected edges, edge-through-node routing, stacked
edges, and unreadable labels. Stop automatic vision repair after two rounds.
When the drawio binary is unavailable or a visual check is inconclusive,
verify the renderer's own DOM instead (--dump-dom on the viewer URL, see
references/troubleshooting.md): read each edge's <path> segments and
label anchor coordinates directly β vision alone both misses geometry
defects and hallucinates new ones.
Show the draft and apply targeted edits. Preserve existing geometry for
local changes. Use sync for source-backed changes and write a reviewable
output; use --prune only when deletion was requested.
After approval, create final requested formats and report both editable source and export paths.
Resolve the available binary once (drawio, draw.io, the macOS app path, or
the Windows executable) and use that exact binary for the run.
# Draft for visual inspection: never use -e here
drawio -x -f png --width 2000 -o diagram.png diagram.drawio
# Final editable PNG
drawio -x -f png -e -s 2 -o diagram.drawio.png diagram.drawio
python3 scripts/repair_png.py diagram.drawio.png
# Final editable SVG/PDF
drawio -x -f svg -e --embed-svg-images -o diagram.svg diagram.drawio
drawio -x -f pdf -e -o diagram.pdf diagram.drawio
Do not combine --width and -s. Embedded PNG exports require
repair_png.py; draft PNGs used by vision must not use -e. On Linux headless,
follow references/troubleshooting.md rather than improvising Electron flags.
If the CLI crashes in a macOS sandbox, try one permitted escalated run, then use
encode_drawio_url.py or deliver XML; do not repeatedly launch it.
0 or 1.<mxGeometry relative="1" as="geometry"/>.data-model-id, semantic properties, manual geometry, and
manual styles intact unless the user requests otherwise.edgeports.py; add waypoints when an
edge still crosses an unrelated shape. There is no CLI-only edge rerouter
that preserves node positions.An attractive diagram can still be wrong. Prefer source-backed relationships, show provenance where useful, distinguish exact extraction from AI inference, and keep architecture review findings framed as prompts. Story HTML must remain self-contained, keyboard usable, and include a text alternative. Never include secrets in node properties or provenance because they are embedded in outputs.
For all focused scripts and composition patterns, read references/toolbox.md;
load only the task-specific reference needed for the current request.
