resolve-deps

Diagnose why Swift Package Manager won't resolve, or why a package that resolved still won't build.

What This Command Does

Launches the spm-conflict-resolver agent. It reads Package.swift and Package.resolved to reconstruct the declared and resolved dependency graphs, then explains the conflict rather than just reporting that one exists.

What It Checks

1. Version conflicts – two packages requiring incompatible versions of a shared transitive dependency
2. "No such module" – traced back to an unresolved package, a renamed product, or a target that never declared the dependency
3. Duplicate symbol link errors – usually the same package vendored twice through different paths
4. Swift 6 compatibility – packages that don't build under the language mode your target uses
5. Resolution vs. build failures – distinguishing "SPM cannot pick versions" from "SPM picked versions that don't compile together"

Usage

/axiom:resolve-deps
