# 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

## Anti-Patterns

- [ ] Do not lead with `--force` / `--legacy-peer-deps` — it hides the conflict and breaks later
- [ ] Do not delete the lockfile as the first move — explain what that actually does
- [ ] Do not give a single fix when several are viable — rank them with trade-offs
- [ ] Do not skip verifying the resolution actually installs/builds
