Select optimal data structure based on operation requirements

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Data Structure Selector Skill ## Purpose Select the optimal data structure based on required operations, their frequencies, and time/space constraints. ## Capabilities - Analyze required operations (insert, delete, query, update) - Match to optimal data structure - Consider time/space trade-offs - Suggest augmentations for custom requirements - Compare alternatives with complexity analysis ## Target Processes - data-structure-implementation - algorithm-implementation - complexity-optimization ## Selection Framework ### Operation Analysis 1. What operations are needed? 2. What are the frequency/priority of each operation? 3. What are the constraints (N, Q, time limit)? 4. Is persistence needed? 5. Are range operations required? ### Common Selection Patterns | Operations | Best Choice | |------------|-------------| | Insert, Delete, Search | BST / Hash Map | | Range sum, Point update | Fenwick Tree | | Range query, Range update | Segment Tree + Lazy | | Union, Find | DSU | | Min/Max with add/remove | Multiset / Heap | | Predecessor/Successor | Ordered Set / BST | ## Input Schema ```json { "type": "object", "properties": { "operations": { "type": "array", "items": { "type": "object"

Select optimal data structure based on operation requirements
How do I install it?
Run `npx skills add a5c-ai/babysitter --skill data-structure-selector --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 a5c-ai/babysitter, a repository with 1,642 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.
