Tools & Capabilities Breakdown

Repo Graph Tools (6)

orient

Get the lay of the land — ALWAYS the first call on a codebase. With no arguments: a counts + entry-points overview plus a `blind spots` note flagging which (language, edge-kind) extractions are partial so you know where to fall back to grep. With `seed=<node>`: the dense structural map scoped to that node's neighbourhood. With `full=true`: the whole-repo dense map (the full context dump). Orient first, then `find` to jump to nodes, `impact` for blast radius, `trace` for flows.

find

Turn any text into the ranked nodes that matter — the on-ramp to the graph. A symbol or keyword returns matching nodes; a pasted stacktrace / failing-test id / diff is resolved to the code it implicates and ranked by relevance. Set `expand=true` to fan out to the surrounding neighbourhood (spreading activation). Every row carries `path:line`, so `read` the top hits directly — no grep.

impact

Blast radius in one call: fan out from one or more nodes to everything they affect (forward) or depend on / are used by (backward), returned as a complete, deduped, Personalized-PageRank-ranked, located closure. Each row carries `path:line`, the edge `via` reason it's in scope, and a `⊘` when the engine finds it unreachable from any entry point (likely dead). Structural import/containment fan-out is excluded — no noise. Depth-1 in both directions is a node's immediate neighbours. Pass several comma-separated nodes to assess a whole diff at once.
