V2 Model Support
mirage-project/mirage
End-to-end pipeline for adding or porting a model to MPK Runtime-V2 — from a compute-graph spec (shapes + draw.io graph + HF checkpoint + TP/EP plan) to a working multi-GPU demo.
Visually verify graphviz2drawio conversion fidelity by rendering a graphviz source side-by-side as a native graphviz PNG and a converted draw.io PNG, then reading both images to compare.

What it does
Compare Render is an agent skill from hbmartin/graphviz2drawio. Visually verify graphviz2drawio conversion fidelity by rendering a graphviz source side-by-side as a native graphviz PNG and a converted draw.io PNG, then reading both images to compare. Use this whenever modifying conversion code in graphviz2drawio/ (nodes, edges, styles, text, layout), fixing a rendering or fidelity bug, or whenever the user asks if output "looks right" or "improved" — even if they don't explicitly ask for a visual check. Always verify visually before declaring a conversion change done.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `evals/evals.json`).
It sits in Testing & QA. It works with draw.io. The repository describes itself as: Convert graphviz (dot) files to draw.io / lucid (mxGraph) format. Beautiful and editable graphs in your favorite editor. The licence is GPL-3.0.
When your agent uses it
- Asks if output looks right
- Improved — even if they dont explicitly ask for a visual check
Example prompts
- “looks right”
- “improved”
- “/compare-render”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Pick 1–3 relevant test inputs from test/ that exercise the feature
- Render the "before" state first if you haven't made changes yet
- Make your change, then render "after"
- Read both PNGs with the Read tool and compare them deliberately,
- Report what you see honestly. Name specific differences ("the edge
What it can do on your machine
Read from SKILL.md and the folder at commit 96c691c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
brewuv
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Compare Render loads about 1.2k tokens when it runs. Until then it costs about 131 tokens; SKILL.md has 491 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- Visually verify graphviz2drawio conversion fidelity by rendering a graphviz source side-by-side as a native graphviz PNG and a converted draw.io PNG, then reading both images to compare. Use this whenever modifying conversion code in graphviz2drawio/ (nodes, edges, styles, text, layout), fixing a rendering or fidelity bug, or whenever the user asks if output "looks right" or "improved" — even if they don't explicitly ask for a visual check. Always verify visually before declaring a conversion change done.
Compare Render: Visual Fidelity Checking
graphviz2drawio converts Graphviz files into draw.io XML. Correctness here is ultimately visual: the draw.io render should look like what graphviz itself produces. Unit tests and spec diffs can pass while the output looks wrong, so any change to conversion logic should end with an actual side-by-side look.
Core workflow
Pick 1–3 relevant test inputs from
test/that exercise the feature you're changing (see the table below). Prefer a small file plus one stress-test file.Render the "before" state first if you haven't made changes yet:
bash ./scripts/compare_render.sh test/directed/hello.gv.txt tmp_render/beforeSkip this if the change is already made — the graphviz PNG is the ground truth either way, so an after-only comparison is still meaningful.
Make your change, then render "after":
bash ./scripts/compare_render.sh test/directed/hello.gv.txt tmp_render/afterThis produces
<base>_graphviz.png(ground truth, rendered bydot) and<base>_drawio.png(your conversion, rendered by the draw.io CLI), plus the intermediate<base>.xml.Read both PNGs with the Read tool and compare them deliberately, checking each of:
- overall layout: node positions and relative arrangement
- node shapes, sizes, fill and border colors
- edge routing (straight vs curved, where they attach), arrowheads and their direction
- labels: text content, placement, font size; edge labels especially
- clusters/subgraphs: bounding boxes present and enclosing the right nodes
Report what you see honestly. Name specific differences ("the edge label sits on top of node B instead of beside the edge") rather than "looks good". If something regressed versus the before render or the graphviz reference, say so — a failed visual check is a finding, not a reason to skip the report.

Catching regressions beyond the file you're focused on
A fix for one feature frequently shifts output for many graphs. After the targeted comparison passes:
Textual spec check — converts every test input and diffs against the committed expected XML in
specs/(ignoring unstable ids):bash uv run ./scripts/test_specs.sh test tmp_outDifferences are not automatically failures — if the new output is better, the specs should be updated (see
scripts/generate_specs.sh). Decide by looking, not by diff size.Visual spec check — renders any spec XMLs you've modified as
_new.png/_old.png(HEAD version) /_reference.png(graphviz) trios:bash ./scripts/render_specs.sh test specs tmp_renderRead the trios for each changed spec to confirm new beats old.
Practicalities
- Run scripts from the repo root. Output dirs (
tmp_render/,tmp_out/) are gitignored — never commit renders. - The script needs
dot(brew install graphviz) and the draw.io CLI (brew install --cask drawio); it tells you which is missing. - The first draw.io CLI invocation can take ~10s while the app cold-starts; later runs are faster.
- If the draw.io PNG comes out blank or missing, the converted XML is likely
malformed — inspect the intermediate
<base>.xmlin the output dir before blaming the renderer.
