drawing-with-pycairo SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
drawing-with-pycairo from oaustegard/claude-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add oaustegard/claude-skills/drawing-with-pycairo@v0.1.0Pins v0.1.0 in mdr.lock. Pin the fingerprint instead.

Draws images, PDF/SVG vector files and animation frames with pycairo, and supplies what cairo lacks: shaped text for Arabic, Indic and other scripts, text along curves, blur/glow/drop shadows, path booleans, stroke-to-outline, and Gouraud-shaded 3D. Use when writing pycairo or cairo drawing code, generative art, custom diagrams or posters rendered in Python, or when cairo output needs non-Latin text, soft effects, merged shapes or shaded surfaces.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Drawing with pycairo Cairo paints paths with solid colours, gradients, mesh gradients and images, and composites them with 20-odd operators. It writes PNG, PDF, SVG and PostScript. It does **not** shape text, filter pixels, combine paths, outline strokes, or do depth. `scripts/cairokit.py` fills each gap; `scripts/selftest.py` exercises all of it. Both were verified on pycairo 1.29.1 / cairo 1.18.0 / Python 3.11. ## Setup ```bash pip install --break-system-packages pycairo numpy uharfbuzz fonttools skia-pathops python3 /mnt/skills/user/drawing-with-pycairo/scripts/selftest.py /tmp/cairo-selftest ``` The self-test prints the cairo version, whether Pango is usable, per-panel timings, and the path of a 2×2 contact sheet. `Read` that sheet: panel A shows joined Arabic in green next to broken toy-API Arabic in red, B shows four boolean results and an outlined wave, C shows glow and a soft shadow, D shows a smooth-shaded torus. Then: ```python import sys; sys.path.insert(0, "/mnt/skills/user/drawing-with-pycairo/scripts") from cairokit import * ``` …

How to install
mdr add oaustegard/claude-skills/drawing-with-pycairo@sha256:3bc996a6ebdace30The line at the top of this page pins the label v0.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
