+# Dependency Management Skill
+
+Investigate whether a dependency is actually necessary, check existing versions/conventions, minimize dependency additions, and update lockfiles deliberately.
+
+## Subagents
+When you need to delegate sub‑tasks, use the `pi-subagents` skill.
+
+**Example:** To evaluate a new dependency, use a **scout** to check if the functionality exists in the standard library, another **scout** to compare versions and licensing of alternatives, and a **reviewer** to verify the lockfile update doesn't introduce transitive conflicts.
+
+*You may adapt the delegation pattern to fit the exact requirements of the codebase.*
+
+## Process
+
+### 1. Necessity
+- Can this be done with stdlib?
+- Is there an existing internal utility?
+- What's the maintenance cost?
+
+### 2. Conventions
+- Check existing similar dependencies
+- Follow version pinning policy
+- Use approved registries
+
+### 3. Minimize
+- Prefer fewer, well-maintained deps
+- Avoid transitive dependency bloat
+- Consider vendoring for small utils
+
+### 4. Update
+- Update lockfiles atomically
+- Test after updates
+- Document breaking changes
