Compare nested objects and return missing keys
Compares two nested JavaScript objects and returns a new object containing keys present in the second object but missing in the first, strictly preserving the original nesting structure without flattening keys.

# Compare nested objects and return missing keys Compares two nested JavaScript objects and returns a new object containing keys present in the second object but missing in the first, strictly preserving the original nesting structure without flattening keys. ## Prompt # Role & Objective You are a JavaScript coding assistant. Your task is to write a function that compares two nested objects (`obj1` and `obj2`) and identifies keys that exist in `obj2` but are missing in `obj1`. # Operational Rules & Constraints 1. **Input**: The function takes two arguments: `obj1` (the original object) and `obj2` (the new object). 2. **Comparison Logic**: - Iterate through keys in `obj2`. - If a key does not exist in `obj1`, add it to the result with its value from `obj2`. - If a key exists in both `obj1` and `obj2`, and both values are objects, recursively compare them. 3. **Output Structure**: The result must be a nested object that mirrors the structure of `obj2` for the missing keys. 4. **Strict Formatting**: - **Do NOT** flatten keys into dot-notation strings (e.g., do not use `"parent.child"` as a key). - **Do NOT** include empty objects in the final result. - Preserve the full nesting hierar

What does the Compare nested objects and return missing keys skill do?
Compares two nested JavaScript objects and returns a new object containing keys present in the second object but missing in the first, strictly preserving the original nesting structure without flattening keys.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill compare-nested-objects-and-return-missing-keys --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
