GYLT-DEV-CONTEXT-ADDON

Prepare a reusable project context so future Claude Code sessions work efficiently on a codebase, without dropping anything into the target repo. Runs the graphify CLI pipeline (AST topology extraction + Leiden clustering, ~10s, $0) then generates a curated README (mechanical + LLM) summarizing communities, structural god nodes, anti-patterns and practical notes for the agent. Stored in `~/.claude/project-contexts/<slug>/` keyed by `basename "$PWD"`. Normally run once per project, regenerable. Invoke from the target repo root — typically the first time you prepare a project so an agent can work on it intelligently, or after a large structural refactor.

Create an Architecture Decision Record (ADR) for the current code repo, stored alongside its agent context in `~/.claude/project-contexts/<slug>/ADR/`. Invoke whenever a structural decision is made — architecture choice, convention, technical arbitration, pivot. Captures the decision from the session context, numbers it per the folder convention, generates a complete ADR (not an empty skeleton), and updates the ADR INDEX. The ADRs are surfaced back to future sessions as a live link by /prepare-project-for-agent.
