ide-explore

A codebase exploration tool that uses an IDE’s language features to map project structure, follow calls between functions, and find where code starts running.

In plain words
What is it for?
Use it when joining a new project or investigating a module, entry point, call chain, or dependency relationship.
Why use it?
It helps when unfamiliar code is difficult to understand by showing how files, modules, and functions connect. It requires the Claude IDE Bridge and a connected VS Code extension.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ide-explore scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

IDE Codebase Explorer

Prerequisites

  1. Check if the getToolCapabilities MCP tool is available to you.
    • Not available (no MCP tool by that name): stop and tell the user: "This skill requires the Claude IDE Bridge with a connected VS Code extension. It uses LSP tools (type hierarchy, call hierarchy, references, hover, inlay hints) that have no CLI equivalent.

      To use this skill:

      1. Start the bridge: npm run start-all (in claude-ide-bridge/)
      2. Ensure the Claude IDE Bridge extension is installed in your IDE
      3. Use the claude --ide session (not remote-control)"
    • Available: call it. If extensionConnected is false: show the same message. If true: proceed.

Explore and explain a codebase using the IDE bridge's full LSP capabilities. Produces a structured architectural overview.

Workflow

Phase 1: Overview

  1. Use getProjectInfo to understand the project type, languages, and frameworks
  2. Use getFileTree with depth 3 to see the directory structure
  3. Use getToolCapabilities to see what language tooling is available
  4. Identify the focus area from the argument: $ARGUMENTS
    • If a specific file: explore that file and its connections
    • If a module/directory: explore the module's public API and internal structure
    • If a question: search for relevant code to answer it

Phase 2: Entry points and architecture

  1. Use searchWorkspace to find entry points (main, index, app.listen, export default, etc.)
  2. Use getDocumentSymbols on key files to list classes, functions, and exports
  3. For the focus area, use getTypeHierarchy on major classes to understand inheritance
  4. Use getCallHierarchy (outgoing) on entry points to trace the startup flow

Phase 3: Dependency mapping

  1. For the focus area's main exports:
    • Use findReferences to see who depends on them
    • Use goToDefinition on imports to trace dependencies
    • Use getHover on key functions to read their type signatures
  2. Use searchWorkspaceSymbols to find related types and interfaces
  3. Build a dependency map: what depends on what
