explain-like-senior
Senior-level code explanations with deep technical insights and context
npx skills add majiayu000/claude-skill-registry --skill explain-like-senior --agent claude-code
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.
# Senior Developer Explanation I'll explain this code as a senior developer would, focusing on the why behind decisions. ## Token Optimization Strategy **Target Reduction:** 60% (4,000-6,000 → 1,500-2,500 tokens) **Optimization Status:** ✅ Optimized (Phase 2 Batch 3B, 2026-01-26) ### Core Optimization Patterns #### 1. Focused Scope Analysis (30-40% savings) **Problem:** Reading entire codebase for context wastes tokens **Solution:** Laser-focus on specified file/function only ```bash # ❌ AVOID: Exploring entire codebase Glob **/*.ts # 500+ tokens Read all related files # 2,000+ tokens # ✅ PREFER: Targeted analysis Grep "class UserService" --output_mode files_with_matches # 50 tokens Read src/services/UserService.ts # 300 tokens ``` **Token impact:** 2,500 → 350 tokens (86% reduction) #### 2. Architecture Context Reuse (20-30% savings) **Problem:** Re-analyzing project architecture each time **Solution:** Leverage cached `/understand` results ```bash # ❌ AVOID: Fresh architecture analysis Glob src/** # 400 tokens Read package.json, tsconfig.json # 500 tokens Analyze framework patterns # 800 tokens # ✅ PREFER: Reuse cached architecture Read .claude/cache/understand/architecture.json

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill explain-like-senior --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 majiayu000/claude-skill-registry, a repository with 534 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.
