# Decisions ADR-style records of single tactical decisions. ## What Belongs Here A decision doc captures **one specific choice**: what was decided, why, and what was ruled out. Keep them short and focused — usually one page. Write one when: - You picked one approach over another and want the reasoning on record. - A decision depends on or supersedes an earlier one (link across docs). - You want future contributors to understand why the code is the way it is. ## Decisions vs Design Docs Use a **design doc** (`internal/design/`) when you're specifying architecture, a feature, or a subsystem — forward-looking, often longer, status ranges from `draft` → `decided` → `implemented` → `superseded`. Use a **decision doc** here when you're recording a single trade-off within that work — short, always `status: decided`. A design doc often spawns several decision docs as implementation choices get made. ## Format ```markdown --- status: decided date: 2026-01-27 --- # Title ## Decision What you decided. Be direct. ## Context Why this came up. What problem triggered the decision. Link related decisions. ## Alternatives Considered - **Option A** — Why not chosen - **Option B** — Why not chosen ## Rationale Why this choice wins. Keep concise. ``` ## File Naming Lowercase with hyphens, name after the subject of the decision: ``` captions.md gestures-as-components.md provider-attach.md ``` ## See Also - [Design Docs](/internal/design/README.md) — Architecture specs and feature designs - [RFCs](/rfc/README.md) — Proposals needing buy-in - [Plans](/.claude/plans/README.md) — Implementation notes - [CLAUDE.md](/CLAUDE.md#design-documents) — How these relate
