Dependency Conflict Resolver

Q: How do I know the Dependency Conflict Resolver output is good?

The skill verifies itself against its own 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.

🔵 Stable🕐 updated 2026-10-06 ✅ 4.8/5 🔷 SkillSpec L3 pm-engineering

Resolve a dependency or version conflict (npm, pip, yarn, pnpm, Maven, Go modules) step by step. Use when an install fails with peer-dependency or version-conflict errors, packages won't co-exist, or a lockfile is fighting you. Produces the conflict explained, the resolution options ranked by safety, exact commands, and how to keep it from recurring.

“npm install fails with a peer-dependency error.”“pip can't resolve these versions.”“These two packages won't co-exist.”“My lockfile keeps fighting me.”

What to give it

▸The install error — the conflict output exactly as the tool printed it

▸The manifest — package.json, requirements.txt, go.mod, pom.xml, whichever applies

▸The lockfile — if one exists, since it is usually where the conflict is pinned

▸The package manager — npm, pnpm, yarn, pip, Maven, Go modules; infer what's missing

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓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

⚠️ What it refuses to do

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
