codebase-explorer
Deep codebase exploration using semantic search and relationship mapping. Use when you need to understand the current codebase.
npx skills add majiayu000/claude-skill-registry --skill codebase-explorer --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.
## Search Query Analysis ### Query Optimization Skill Codanna's semantic search works best with technical terms and specific concepts. Analyze the situation and optimize your codebase explore queries for code search: Examples: 1. **If vague** (e.g., "that parsing thing") → Make it specific (e.g., "language parser implementation") 2. **If a question** (e.g., "how does parsing work?") → Extract keywords (e.g., "parsing implementation process") 3. **If conversational** (e.g., "the stuff that handles languages") → Use technical terms (e.g., "language handler processor") 4. **If too broad** (e.g., "errors") → Add context (e.g., "error handling exception management") **OptimizedQuery**: _{Claude: I will write my optimized query here, then use it below}_ Execute this command with your optimized query: ## Your Workflow <Workflow> ### Gather Context <Step_1 GatherContext> Use the Bash tool to perform semantic code search: Execute: `codanna mcp semantic_search_with_context query:"$OptimizedQuery" limit:5` **What Codanna returns:** - Relevance scores (how well each result matches) - Symbol signatures and documentation - Relationships (calls, called_by, implements, defines) - File locations wi

What does the codebase-explorer skill do?
Deep codebase exploration using semantic search and relationship mapping. Use when you need to understand the current codebase.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill codebase-explorer --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.
