RepoSkillOpt — As-Is Architecture Analysis (Canonical Skill)

Purpose

This is the repo-specializing analysis layer of RepoSkillOpt. The generic understanding skill (repo-skillopt) is unchanged — it produces the repo-neutral Repository Specification. This skill specializes on a specific repository: it deepens that Repository Specification into an evidence-grounded view of the current architecture and answers "what would a change ripple into?" — before anything is touched. It produces an Architecture View and a Change-Impact (blast-radius) Analysis, and is the analyze as-is stage the plan to-be skill (repo-orchestration) consumes. The skill's own content is vendor-neutral (no coding-agent runtime dependency); its output is repo-specific.

Trigger Conditions

Activate when the user asks to map the architecture, assess dependencies/coupling/layering, or evaluate "what would change if we… / is it safe to change X" — or recognizable equivalents. Do not activate for unrelated requests.
