Overview
Who it's for
Foremerge
Developers running several coding agents on the same project at once.Geiger
Developers and IT teams who want to know what AI tooling is installed and what it can access.Problem
Foremerge
Parallel agents in separate worktrees can each produce correct-looking changes that undo each other when merged.Geiger
AI agents and plugins can run commands, read files and hold credentials, but they're configured in dotfiles nobody checks.Solution
Foremerge
A local coordination layer with a deterministic conflict detector that flags intent conflicts early.Geiger
One scan that finds agent configs across ecosystems, labels their exposure, redacts credentials and suggests fixes.What makes it unique
Foremerge
Detects conflicts in intent, not just in lines of code, and installs itself from a one-line prompt to your agent.Geiger
Zero dependencies and read-only: it writes nothing unless you ask for a JSON report.
