Dependency Conflict Resolver Skill

Untangle "could not resolve dependency" hell into a clear, ranked plan.

Working from a brief

Infer the package manager and ecosystem from the error or files mentioned; label assumptions (assumed — confirm). Always deliver a concrete resolution path even from just the error text.

Input

The install error / conflict output, plus (if given) the manifest (package.json, requirements.txt, go.mod…) and lockfile, and the manager. Infer what's missing.

Output Structure

The conflict

Plain-English: package A needs X of C, package B needs Y of C, and they can't both be satisfied (name the actual packages/versions from the input).

Options (ranked by safety)

1. Safest — e.g. align versions, upgrade the constrained package, or find a compatible range. Exact command.
2. Pragmatic — e.g. an override/resolution (overrides, resolutions, constraints file) with the exact snippet — and the risk it carries.
3. Last resort — e.g. --legacy-peer-deps / --force — clearly flagged as masking the problem, not fixing it.

Give the exact commands/edits for each, and a recommendation of which to pick and why.

Verify & prevent

How to confirm the fix (npm ls <pkg>, a clean reinstall, the build), and one habit to avoid recurrence (lockfile committed, renovate/dependabot, version pinning policy).

Quality Checks

• Names the actual conflicting packages and versions from the input
• Options are ranked by safety with the trade-off of each stated
• --force/--legacy-peer-deps-style escapes are flagged as masking, not fixing
• Includes a verification step
