environment-validation

Unify toolchain versions and validation rules (project, gitignored). Use when environment validation guidance is required.

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.
