About This License

The IDK-Strongleft-WTF License ("With These Footnotes") extends the IDK-Strongleft License for projects that include third-party code. Because IDK-Strongleft is a strong copyleft license, this wrapper includes copyleft boundary analysis for each dependency.

Your Original Work

Covered by the IDK-Strongleft License — strong copyleft with network interaction clause, patent non-assertion, and AI authorship acknowledgment.

Third-Party Code

Keeps its own license. Copyleft may extend to "combined" works but NOT to "aggregated" works. Each dependency is classified in the schedule.

How It Works

The IDK-Strongleft-WTF License has seven parts:

  1. Part I: Incorporates the full IDK-Strongleft License
  2. Part II: Copyleft boundaries — Combined Works vs Mere Aggregation, four compatibility categories
  3. Part III: Dependency Schedule with Integration Type (combined/aggregated) and Compatibility columns
  4. Part IV: File naming convention
  5. Part V: Reconciliation — copyleft interaction, source obligations, network obligations
  6. Part VI: Supplemental severability
  7. Part VII: License to the document itself
Accuracy Matters: For copyleft projects, the Integration Type classification is legally significant. If a dependency is incorrectly classified as "aggregated" when it's actually "combined," the distribution may violate the license. Independent verification is strongly recommended.

Quick Start

Option 1: Use the Scanning Agent

An AI agent prompt is included that can scan your project, identify all third-party dependencies and their licenses, classify integration types and compatibility, populate the dependency schedule, rename the output file, and handle all the formatting — automatically.

  1. Download both license files to your project root: 
    curl -o LICENSE-IDK-Strongleft https://idklaw.net/license-strongleft/0.0.1/LICENSE-IDK-Strongleft
curl -o LICENSE-IDK-Strongleft-WTF https://idklaw.net/license-strongleft-wtf/0.0.1/LICENSE-IDK-Strongleft-WTF
  2. Give the scanning agent prompt to your AI coding assistant (Claude, Cursor, Copilot, etc.). Copy it below, paste it into your tool, and let it do the work. The agent handles the copyleft-specific Integration Type and Compatibility columns for you.

The scanning agent generates a new IDK-Strongleft-WTF file from scratch. The update agent incrementally updates an existing one when dependencies change.

Option 2: Manual Setup

If you prefer to populate the dependency schedule by hand:

  1. Populate the Dependency Schedule in LICENSE-IDK-Strongleft-WTF (Part III). For each dependency, classify the Integration Type (combined or aggregated) and Compatibility (compatible, permissive, or incompatible).
  2. Rename the file according to the naming convention in Part IV.
  3. Add SPDX identifiers to your source files:
