Code Teardown

Category: Engineering  ·  Sub-category: testing  ·  Last updated:
Reverse-engineer an external repository or codebase (competitor OSS, reference implementation, trending project) and map every adoptable idea — architecture, code patterns, DX, tooling, testing, docs conventions — into a teardown report where each finding carries evidence (file:line), an adopt/adapt/already-have/reject verdict, and a constraint rationale for our context. Use when asked "faz um teardown desse repo", "analisa esse repositório pra ideias", "o que dá pra aproveitar desse projeto open-source", "evaluate X repo for insights", "what can we learn from this codebase". Read-only toward the target; clones to External HD. For live apps use app-teardown; to onboard for contributing use adt-repo-intake; to document our own architecture use doc-and-modernize.

From the source SKILL.md

Reads someone else's codebase to answer one question: what do they do that WE should do? Same contract as app-teardown (live apps); this one targets repos and reads code. Output is a decision artifact with verdicts, not an architecture tour — for "how does X work" documentation use doc-and-modernize.

What this skill does

Code Teardown is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/code-teardown/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when asked "faz um teardown desse repo", "analisa esse repositório pra ideias", "o que dá pra aproveitar desse projeto open-source", "evaluate X repo for insights", "what can we learn from this codebase". Read-only toward the target; clones to External HD.

Who uses this skill
