# arc42 Documentation Skill This skill is vendored under the MIT license, copyright Melodic Software. The license is stored beside this file and must stay with any copy. It owns `docs/ARCHITECTURE.md` together with `c4-model`, as the project file set in `buzz-team-communication` states. The only change from the original is the step list below, which no longer requires a `docs-management` skill or a Perplexity MCP server; neither ships with this plugin. ## When to Use This Skill Use this skill when: - **Arc42 Documentation tasks** - Working on arc42 architecture documentation template and guidance - **Planning or design** - Need guidance on Arc42 Documentation approaches - **Best practices** - Want to follow established patterns and standards ## Overview Create comprehensive architecture documentation using the arc42 template. ## MANDATORY: Documentation-First Approach Before creating arc42 documentation: 1. **Read the project's existing architecture documentation** before writing, so the result continues it instead of replacing it 2. **Check the current arc42 version** at [`arc42.org`](https://arc42.org) when a web lookup is available, and say so when it is not 3. **Base guidance on the official arc42 template** ## arc42 Template Structure ```text arc42 Template (12 Sections): ┌─────────────────────────────────────────────────────────────────────────────┐ │ 1.
