✅ 5/5
🔷 SkillSpec L3
pm-engineering
Explain what a piece of code does in plain English, at the depth the reader needs. Use when asked to explain code, walk through a function, understand an unfamiliar snippet, or onboard to a file. Produces a one-line summary, a step-by-step walkthrough, the non-obvious parts called out, and any bugs or smells spotted along the way.
✅ The bar it holds itself to
Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.
✓The one-line summary stands alone
✓The walkthrough explains *why*, not just restating the code in words
✓Non-obvious behaviour (side effects, complexity, edge cases) is surfaced
✓Any bug/smell spotted is flagged with a fix
⚠️ What it refuses to do
Do not narrate line-by-line in English ("this line sets x to 5") — explain intent and structure
Do not skip the gotchas — the value is in the non-obvious parts
Do not assume expert level if the question reads like a beginner's (or vice-versa)
Do not ignore a bug you can see just because you weren't asked to review it
