progressive-disclosure

by NCMcClure

Design and maintain file-based progressive disclosure memory systems for Claude Code projects. Use when a project needs durable knowledge persistence across sessions — architecture decisions, technical learnings, domain expertise, or people context that outlasts any individual task. Triggers include requests for "project memory", "session persistence", "knowledge base", "memories directory", "progressive disclosure", "remember across sessions", or "capture learnings". Complements the autonomous-loop skill: loops handle intra-task state (progress.txt), memory systems handle institutional knowledge that accumulates over the lifetime of a project.

interview-designer

by mikonos

Analyze resumes and design interview strategies using evidence-based methodology. Transforms interview prep from "read resume → ask questions" into "define standard → forensic evidence → future simulation". Combines Geoff Smart's Topgrading, Lou Adler's performance-based hiring, and Daniel Kahneman's bias control. Use when preparing for interviews, creating structured interview guides, or designing questions to validate candidate competencies.

react-router-loader-performance

by adrianbrowning

React Router v7 loader performance optimization techniques. Use when optimizing TTFB, eliminating waterfalls, consolidating database queries, or streaming secondary data in loaders. Triggers on "slow loaders", "optimize TTFB", "speed up React Router", "loader performance", or when loaders exceed 500ms response time.

goldy

by SacredTexts

"Global planning/orchestration skill. Use for: (1) Gold Standard plan creation and phased execution, (2) stack-aware decisions across TanStack/React/Neon/Drizzle/WorkOS/Radix/shadcn and other stacks, (3) session memory and deterministic resume capsules, (4) long-running /goldy-loop phase automation with checkpoints and resume chaining, (5) UI/UX module reuse from ui-ux-pro-max when design output is needed, (6) browser-based bug investigation and smoke testing via auto-detected backend (Chrome Extension for Claude Code, Playwright for Codex). Trigger for planning, roadmap, phase, architecture, implementation sequencing, or when user asks for /goldy or /goldy-loop behavior. Also auto-invokes on any coding work that lacks a pre-existing plan: fix, bug, implement, build, add, create, refactor, migrate, update, upgrade, feature, endpoint, component, test, debug, deploy, optimize, integrate, change, modify, remove, delete."

supabase-postgres-best-practices

by pm-minji

Postgres performance optimization and best practices from Supabase. Use this skill when writing, reviewing, or optimizing Postgres queries, schema designs, or database configurations.

Engram Conditional Memory (N-gram Hash Lookup + Offload/Prefetch)

by sovr610

This skill should be used when the user asks to "implement engram memory", "add N-gram hash lookup", "implement tokenizer compression", "add engram layer", "implement CPU offload embeddings", "add async prefetch", "implement multi-head hashing", "add context-aware gating", "implement depthwise causal conv", "add engram encoder", "implement hash embedding retrieval", "add collision mitigation", "implement offloadable embedding", "add prefetch scheduler", "implement engram augmented layer", "add residual fusion", "implement RMSNorm gating", "add engram telemetry", "implement streaming N-gram cache", "add prime-sized hash tables", "implement tokenizer equivalence merging", or mentions engram memory, N-gram hashing, deterministic addressing, CPU offload + prefetch, tokenizer compression, context-aware gating, depthwise causal convolution, hash embedding, encoder-competition mode, layer-augmentation mode, or DeepSeek-style conditional memory in the cognitive pipeline.

hiram-performance

by christopheraaronhogg

Provides expert performance analysis, bottleneck identification, and optimization assessment. Use this skill when the user needs performance audit, Core Web Vitals review, or scalability evaluation. Triggers include requests for performance review, load testing guidance, or when asked to identify bottlenecks. Produces detailed consultant-style reports with findings and prioritized recommendations — does NOT write implementation code.
