Claude Code plugin that gives Claude graph-aware context for every edit. Before each Grep / Glob / Bash invocation, the CodraGraph hook surfaces the blast-radius, callers, and process participation for symbols Claude is about to touch. Claude can also load FeatureCluster packs for product areas like Settings, Auth, AI, or Billing, so it does not have to grep blindly.

Install

# Install the codragraph CLI first
npm install -g @codragraph/cli
# or: bun add -g @codragraph/cli --trust
codragraph setup

# Then add the plugin to Claude Code
claude plugins install integrations/claude

What's in the box

Hooks: PreToolUse on Grep/Glob/Bash runs a bounded side-channel CodraGraph query and prepends the result to Claude's context. PostToolUse only performs a cheap staleness check; it never starts analyze in the background.
Feature context: feature_clusters and feature_context expose focused files, line ranges, dependencies, and flows for one product area.
Skills: 7 skill packs Claude can invoke directly:
- codragraph-impact-analysis — what breaks if I change this?
- codragraph-pr-review — review a diff with full graph context
- codragraph-refactoring — coordinated multi-file edits
- codragraph-exploring — orient in a new codebase
- codragraph-debugging — trace a bug back to its root
- codragraph-guide — generate ARCHITECTURE.md from the graph
- codragraph-cli — invoke any codragraph CLI command from chat

Configuration

API keys live in ~/.codragraph/config.json — the same file the CLI uses. Set them with:

codragraph config set claude --api-key sk-ant-...
codragraph config set openai --api-key sk-...
