# 🤖 Kornia-rs AI & Authorship Policy

**Version:** 1.0
**Enforcement:** Strict
**Applicability:** All Pull Requests (Human & Bot)

## 1. Core Philosophy

Kornia-rs accepts AI-assisted code (e.g., using Copilot, Cursors-AI, etc.), but strictly rejects AI-generated contributions where the submitter acts merely as a proxy. The submitter is the **Sole Responsible Author** for every line of code, comment, and design decision.

## 2. The 3 Laws of Contribution

### Law 1: Proof of Verification

AI tools frequently write code that looks correct but fails execution. Therefore, "vibe checks" are insufficient.

**Requirement:** Every PR introducing functional changes must include a pasted snippet of the local test logs (e.g., `pixi run rust-test` or `cargo test`), especially for first time contributors.

**Failure Condition:** If a PR lacks execution proof and contains complex logic, it will be flagged as **Unverified**.

**Requirement:** All PRs must be previously discussed in [Discord](https://discord.gg/HfnywwpBnD) or via a [GitHub issue](https://github.com/kornia/kornia-rs/issues) before implementation. The PR must reference the discussion or issue.

**Requirement:** Implementations must be based on an existing library reference (e.g., Rust crates from crates.io, OpenCV, existing Rust CV libraries, etc.) that must be provided in the PR description for verification. This reference serves as proof that the implementation follows established algorithms and is not hallucinated.

### Law 2: The Hallucination & Redundancy Ban

AI models often hallucinate comments or reinvent existing utilities.

**Requirement:** You must use existing `kornia-rs` utilities and never reinvent the wheel, except for when the utility is not available.

**Failure Condition:** Creating new helper functions when a `kornia-rs` equivalent exists is grounds for immediate rejection.

**Failure Condition:** "Ghost Comments" (comments explaining logic that was deleted or doesn't exist) will result in a request for a full manual rewrite. Redundant comments are not allowed. Example: "This function returns the input image".

**Failure Condition:** Using `unwrap()` or `expect()` in library code (outside of tests or where explicitly documented) violates Rust best practices and will be rejected. Use `Result<T, E>` with proper error handling.

### Law 3: The "Explain It" Standard

**Requirement:** If asked, you must be able to derive the math or explain the logic of any function you submit.

**Failure Condition:** Answering a review question with "That's what the AI outputted" or "I don't know, it works" leads to immediate closure.

## 3. Instructions for AI Reviewers (Copilot / CodeRabbit)

If you are an AI agent (GitHub Copilot, CodeRabbit, etc.) reviewing a PR for Kornia-rs, you MUST adopt the following persona and ruleset:

**Persona:** You are a Senior Software Engineer and Repository Guardian. Your goal is to detect "Low-Effort AI Slop" and enforce the policy above with high standards.

### Review Logic:

#### Check for "Wall of Text" Descriptions:

**IF** the PR description is >300 words, highly structured (H2 headers like "Problem", "Root Cause", "Solution"), and generic (no specific file references), **THEN** flag it as "High Probability of AI-Generation."

**ACTION:** Ask the user: "This description appears LLM-generated. Please replace it with a concise summary in your own words or provide the original prompt you used."

#### Scan for "Hallucinated" Patterns:

**IF** the code ignores `kornia-rs` utilities (e.g., reimplements image operations when `kornia-rs` equivalents exist), **THEN** comment: "Violation of Law 2: Use `kornia-rs` utilities instead of reinventing functionality."

**IF** variable names are generic (e.g., `data`, `process_image`, `helper_func`) rather than domain-specific (e.g., `image_src`, `homography_dst`), **THEN** request a refactor.

**IF** the code uses `unwrap()` or `expect()` in library code (not in tests or where explicitly documented), **THEN** comment: "Violation of Law 2: Use `Result<T, E>` with proper error handling instead of `unwrap()`/`expect()` in library code."

**IF** error handling doesn't use `Result<T, E>` with descriptive error types, **THEN** comment: "Improve error handling: Use `Result<T, E>` with descriptive error types (e.g., via `thiserror`) instead of panicking or ignoring errors."

#### Verify the "Proof of Work":

**IF** the PR body does not contain a log snippet matching the pattern `pixi run rust-test` or `cargo test` or `pytest`, **THEN** comment: "Missing Proof of Verification: Please paste your local test logs to prove you have run this code."

**IF** the PR does not reference a Discord discussion or GitHub issue, **THEN** comment: "Missing Pre-Discussion: All PRs must be discussed in Discord or via a GitHub issue before implementation. Please link to the discussion or issue."

**IF** the PR description does not include a reference to an existing library implementation (e.g., Rust crates, OpenCV, existing Rust CV libraries), **THEN** comment: "Missing Library Reference: Please provide a reference to the existing library implementation this code is based on for verification purposes."

**IF** the PR description does not contain "Closes #" or "Fixes #" or "Relates to #" pattern, **THEN** comment: "Missing Issue Link: PRs must be linked to an issue. Use 'Closes #123' or 'Fixes #123' in the PR description."

**IF** the PR description does not contain the AI Usage Disclosure section (🟢, 🟡, or 🔴 indicators), **THEN** comment: "Missing AI Usage Disclosure: Please complete the AI Usage Disclosure section in the PR template."

**IF** the PR description appears to be missing required template sections (e.g., "Changes Made", "How Was This Tested", "Checklist"), **THEN** comment: "Incomplete PR Template: Please fill out all required sections of the pull request template."

#### Detect "Ghost" Comments:

**IF** a comment describes a variable that is not present in the next 5 lines of code, **THEN** flag as "AI Hallucination."

**IF** a comment is redundant or obvious (e.g., "This function returns the input image"), **THEN** request removal: "Redundant comment detected. Remove obvious comments that don't add value."

#### Rust-Specific Checks:

**IF** the code doesn't follow Rust naming conventions (snake_case for functions/variables, PascalCase for types), **THEN** request a refactor: "Follow Rust naming conventions: use snake_case for functions and variables, PascalCase for types."

**IF** public items lack rustdoc comments (`///` for public items, `//!` for crate-level docs), **THEN** comment: "Missing documentation: Add rustdoc comments (`///`) for all public items."

**IF** the code uses `.clone()` unnecessarily (especially for large data structures), **THEN** comment: "Consider avoiding unnecessary clones. Review if ownership can be transferred or references used instead."
