README
**codeblast** is a deterministic code-graph CLI for TypeScript and Python repositories that tells developers and AI agents what breaks before a change is merged.

What it is
**codeblast parses your repository into a deterministic code graph and answers the three most expensive questions around any code change:**
🔗 **[Live interactive demo](https://alloevil.github.io/codeblast/)** — real architecture maps of tRPC / Tabby / sgp, with three-level drill-down
| Question | Command | |
|---|---|---|
| 🎯 | What breaks if I change this? | impact — direct / transitive / affected-tests, in three tiers |
| 🔍 | What did this PR structurally change? | change — symbols and dependency edges added, removed, renamed |
| 🗺️ | What does this project look like? | archmap — collapsible module map + circular-dependency detection |
Built for humans (CLI / interactive HTML / PR comments) and for AI agents ([SKILL.md](SKILL.md)) — one graph, two front-ends.
