# Architecture Compass ADR Authoring ## Goal Turn rough decision notes into a reviewable first pull request that adds a reusable Architecture Compass decision and adopts the same decision in `stark-ai-de/agent-skills`, without making the maintainer restate the repository-specific PR prompt. ## When to use - A maintainer wants to add a new public, target-repository Architecture Compass ADR or propose a successor to one. - The input is a rough idea, discussion, or partial requirements list. - The requested outcome includes a pull request in `stark-ai-de/agent-skills`. ## When not to use - The task is to adopt an existing Architecture Compass ADR in another repository; use `architecture-compass`. - The decision is Architecture Compass implementation policy or belongs in `AC-INTERNAL-*`; this paired-adoption workflow does not apply. - The task only changes implementation under an already accepted ADR. - The user has not authorized repository writes or pull-request creation; stop after the requirements draft. ## Inputs to inspect - The user's decision intent, constraints, examples, and explicit exclusions. - Current `main`, repository instructions, `docs/adrs.md`, `docs/adrs/TEMPLATE.*.md`, and relevant repository ADR triplets. - `skills/engineering-workflows/architecture-compass/SKILL.md`, `skills/engineering-workflows/architecture-compass/references/adr-catalog.md`, and relevant exposed ADR triplets. - `scripts/validation/architecture-compass/validate.mjs`, its decision
