Code context for people and agents. Find a function’s callers. Trace the path through your code. Know what breaks before you break it.
Simulated replay — the arbor commands and their output are real (tokio @ 178k LOC). Methodology: BENCHMARKS.md
v3.0.3 · Rust calls through module paths, macros and self are now edges. arbor diff --base origin/main reports a branch the way its pull request shows it, and a new function no longer inherits the blast radius of the file it lands in. Same-named symbols in different languages stay apart, and a graph built on another branch is refreshed instead of answered from. New: arbor receipt, a plain-English account of what each agent turn changed. Release notes
Why Arbor
Most AI coding tools treat code as text. Arbor builds a semantic dependency graph — functions, classes, and modules as nodes; calls, imports, and inheritance as edges — then answers execution-aware questions with deterministic precision:
No keyword guessing. No embedding hallucinations. One graph, every interface.
Where the graph is unsure, it says so — edges carry a confidence, and ambiguous resolutions are labelled rather than hidden. An honest unknown beats a confident wrong answer.
What's new in v3.0.3
A fix release. Every item below was a wrong answer, not a missing feature, and each ships with a regression test.
Shortened. The full README is on GitHub.
Nothing above is checked by us. What we check is on the safety report.
