Codebase Explorer
Search and understand code structure, dependencies, and architecture using semantic analysis.
Installation
- Make sure Claude is on your device and in your terminal.
Skills load from
~/.claude/skills/when Claude Code starts up β so you need it on your machine first. If you don't have it yet, install it once with the command below, then runclaudein any terminal to verify.One-time setupnpm i -g @anthropic-ai/claude-codeAlready have it? Skip ahead.
- Paste into Claude Code or into your terminal.
This copies the whole skill folder into
~/.claude/skills/codebase-exploration-giancarloerra/β the SKILL.md plus any scripts, reference docs, or templates the skill ships with. Safe default: works for every skill.Faster alternative (instruction-only skills)
Skips the clone and grabs only the SKILL.md file. Don't use this if the skill ships Python scripts, reference markdowns, or asset templates β they won't be downloaded and the skill will fail when it tries to load them.

Quit and reopen Claude Code (or any other agent that loads from
~/.claude/skills/). New skills are picked up on startup. - Just ask Claude.

When Claude uses it
Explore and understand codebases using SocratiCode semantic search, dependency graphs, and context artifacts. Use when exploring code, understanding architecture, finding functions/types, analysing dependencies, searching database schemas or API specs, or when socraticode/codebase_search tools are available. Activates when the user asks about code structure, wants to find where a feature lives, or needs to understand how code is organised.
What this skill does
SocratiCode Codebase Exploration
Use SocratiCode MCP tools to explore codebases efficiently. The core principle: search before reading β the index gives you a map of the codebase in milliseconds; raw file reading is expensive and context-consuming.
Workflow
1. Start most explorations with codebase_search
Hybrid semantic + keyword search (vector + BM25, RRF-fused) runs in a single call.
- Broad queries for orientation: "how is authentication handled", "database connection setup", "error handling patterns"
- Precise queries for symbol lookup: exact function names, constants, type names
- Prefer search results to infer which files to read β do not speculatively open files
- Use
fileFilterto narrow to a specific file path,languageFilterfor a specific language - Adjust
minScore(default 0.10) for precision vs recall β lower for more results, higher for stricter matching
When to use grep instead: If you already know the exact identifier, error string, or regex pattern, grep/ripgrep is faster and more precise β no semantic gap to bridge. Use codebase_search when exploring, asking conceptual questions, or when you don't know which files to look in.
2. Follow the graph before following imports
Use codebase_graph_query to see what a file imports and what depends on it before diving into its contents. This prevents unnecessary reading of transitive dependencies.
codebase_graph_queryβ imports and dependents for any file (pass relative path)codebase_graph_statsβ architecture overview: total files, edges, most connected files, orphans, language breakdowncodebase_graph_circularβ find circular dependencies (these cause subtle runtime bugs; check proactively when debugging unexpected behaviour)codebase_graph_visualizeβ Mermaid diagram colour-coded by language, circular deps highlighted in red. Passmode: "interactive"to open a self-contained HTML explorer (file + symbol views, blast-radius overlay, search, PNG export β works offline) instead.
The graph is auto-built after indexing. Use codebase_graph_status to check if the graph is ready.
3. Read files only after narrowing via search
Once search results clearly point to 1-3 files, read only the relevant sections. Never read a file just to find out if it's relevant β search first.
A single codebase_search call returns ranked, deduplicated snippets from across the entire codebase in milliseconds. This gives you a broad map at negligible token cost β far cheaper than opening files speculatively.
4. Leverage context artifacts for non-code knowledge
Projects can define a .socraticodecontextartifacts.json config to expose database schemas, API specs, infrastructure configs, architecture docs, and other project knowledge that lives outside source code.
codebase_contextβ list available artifacts (names, descriptions, paths, index status)codebase_context_searchβ semantic search across all artifacts (or filter withartifactName)- Artifacts are auto-indexed on first search and auto-detect staleness
Run codebase_context early to see what's available. Use codebase_context_search before asking about database structure, API contracts, or infrastructure.
5. Check status if something seems wrong
codebase_statusβ check index status, progress, watcher state, graph status- If search returns no results, the project may not be indexed yet
- If the watcher is inactive, results may be stale β run
codebase_updateor start the watcher
6. Get an overview of all tools
codebase_aboutβ quick reference of all SocratiCode tools and a typical workflow
