opencv SKILL.md skillA
opencv from marielynneblock/arcanum-artifex is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add marielynneblock/arcanum-artifex/opencv@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

[TODO] Define the specific workflow this skill standardises, including default libraries, quality checks, and expected deliverables.
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
## What this skill does [TODO] Define the specific workflow this skill standardises, including default libraries, quality checks, and expected deliverables. ## When to use it [TODO] List concrete user intents and trigger phrases that should activate this skill. ## Instructions 1. Clarify the objective, data assumptions, and success metrics. 2. Execute a leakage-safe and reproducible workflow for this skill domain. 3. Validate outputs with diagnostics, edge-case checks, and documented caveats. ## Output format - A concise plan of action - Executable code or commands - Validation summary with assumptions and risks ## Examples ### Example 1 - baseline workflow **Input:** User asks for help in opencv. **Expected output:** A reproducible, validated workflow using the skill's core tools. ## Notes - Prefer documented, stable APIs over experimental shortcuts. - Record assumptions explicitly when data quality or labels are uncertain.

How to install
mdr add marielynneblock/arcanum-artifex/opencv@sha256:83d27f542303fea8The line at the top of this page pins the label v1.0.0, 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.
