## Purpose

Validate that the active development toolchain satisfies governance requirements (versions, availability, and basic configuration) and produce a concise status signal that downstream agents and skills can consume.

## IO Semantics

Input: Current shell/environment, installed tools, and configuration files.
Output: Validation results (pass/fail plus key findings) and remediation hints.
Side Effects: May trigger separate installation or remediation commands when invoked by higher-level workflows, but this skill itself should focus on detection and reporting.
