Big Indexer
Index by behavioral role and emits architectural boundaries
BGI tries to group code based on what the code actually does (its behavior), not just which file imports what. - ahmedxuhri/bigindexer
What you can do with it
"Where should this boundary be before we refactor?"
BGI groups units by behavioral role (COV tokens + DRS clustering) so likely component boundaries are visible.
"Which subsystem coupling is risky?"
BGI surfaces high-coupling seams and fuse-boundary signals between clusters so integration risk is easier to spot.
"How do we plug architecture data into automation?"
BGI emits machine-readable artifacts (bgi-graph.json, fuse-graph.json) plus optional human context (bigindexer.md).
"How do we make AI changes less random?"
MCP tools (task_fingerprint, behavioral_twins, twin_context) ground prompts in in-repo behavior patterns.
"Can I run this automatically on PRs as a live example?"
Yes — use the dedicated action repo ahmedxuhri/bigindexer-pr-risk-bot to auto-comment PRs with blast radius, seams, and risk hints.
