Can agents use it anyway?
Yes. Arbor produces the grounded brief; an agent can use that brief to write tests or keep a patch scoped.

Pricing
Start free. Pay when it has earned it.
Use Arbor where the feedback is easiest to trust: one PR comment, one path map, one clear next check. Your first 10 walks are free on any repository, public or private — no card, and a walk that fails never counts against them. After that, Pro is $9 per developer and Team is $60 flat for up to 10.
Pricing
Half the price of LLM reviewers.
None of the guessing.
Your first 10 walks are free, no card. Deterministic graph walks cost us almost nothing per PR, so they cost you less too — no usage metering, no per-repo surcharge.

FAQ
Common questions.
How Arbor walks PRs, how agents can use the brief, and how it fits a small-team workflow.
Does Arbor run my code?
No. The worker parses and walks source structure. It does not execute your app, tests, install scripts, or runtime commands.
What if the map is incomplete?
The missing edge is named in the PR so a reviewer or agent knows where the uncertainty is.
