e2e-ocr SKILL.md skillA
e2e-ocr from nerds-odd-e/doughnut is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

E2E OCR assertions with Tesseract.js for canvas-only UI such as PDF pages in Cypress page objects. Use when asserting canvas-only E2E text with OCR.
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
# E2E OCR Rules
Use this skill when asserting text that is not in the DOM, such as PDF content drawn only to `<canvas>`. Keep OCR in test infrastructure, not product code.
## Tesseract Setup
- Use `tesseract.js`, a root devDependency, for canvas-only assertions via `cy.task`.
- Register a Node task in `e2e_test/config/common.ts`.
- The task should call `tesseract.js` `createWorker` and `recognize` on image bytes, such as base64 PNG without the `data:image/png;base64,` prefix.
- Example task name: `ocrCanvasImage`.
## Language Data
- Commit `e2e_test/tesseract/eng.traineddata` uncompressed.
- Pass `langPath` and `cachePath` to that directory when creating the worker.
- This prevents Tesseract from writing `eng.traineddata` to the repo root. Root-level traineddata files are gitignored as a fallback.
## Page Object Pattern
- Wait until the canvas has real ink before OCR. Sampling `getImageData` for dark pixels is better than checking only non-zero alpha, because an empty white fill can still have alpha.
- Export with `toDataURL("image/png")`.
- Strip the data URL prefix.
- Use `cy.task(..., { timeout: ... })` for slow OCR.

How to install
mdr add nerds-odd-e/doughnut/e2e-ocr@sha256:309d62635643f9adThe line at the top of this page pins the label git:20260916.b334104, 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.
