Lists multiple specific concrete actions: 'Diagnoses and resolves package dependency conflicts' with explicit types 'version mismatches, diamond dependencies, cycles' and names specific ecosystems 'npm, pip, Maven, Cargo'.

Clearly answers both what ('Diagnoses and resolves package dependency conflicts...across npm, pip, Maven, Cargo') AND when with explicit 'Use when' clause covering three specific trigger scenarios: install failures, version incompatibilities, and upgrade breakages.

Excellent coverage of natural terms users would say: 'dependency conflicts', 'version mismatches', 'install fails', 'resolution error', 'incompatible versions', 'upgrading', 'breaks' - all phrases developers naturally use when encountering these issues.

Clear niche focused specifically on dependency resolution conflicts with distinct triggers like 'resolution error', 'diamond dependencies', 'incompatible versions' - unlikely to conflict with general coding or package management skills.

Every section earns its place. No explanation of what dependencies are or how package managers work. Tables are dense and scannable. The worked example is necessary to show the resolution process, not padding.

Provides exact commands for every ecosystem (npm ls, cargo tree -i, mvn dependency:tree), concrete override syntax for each package manager, and a complete worked example with real error messages and JSON config. Copy-paste ready throughout.

Clear 3-step sequence (see tree → diagnose → resolve) with explicit validation checkpoint ('Test. Run the app. Chart renders → done'). The resolution ladder in the worked example shows feedback loop: override → test → if breaks, fork and fix.

Well-organized with tables for quick reference, expandable worked example, and clear sections. At ~150 lines, appropriately self-contained without needing external files. The output format template at the end provides structure without bloat.
