# Environment Health Diagnose the user's Claude Code environment health. Outputs either an inline markdown report or a self-contained interactive HTML dashboard. Covers 10 diagnostic areas — 6 graded scores against official thresholds (§4 splits into §4a at-rest and §4b post-compact; §9 Skill Security Scan uses security baselines rather than docs-cited thresholds) plus 5 observational areas (raw numbers, no tier). ## Instructions ### Input Parsing Parse these arguments: | Flag | Values | Default | Meaning | |------|--------|---------|---------| | `--format` | `html` \| `md` | `html` | Output mode. `html` generates a full interactive dashboard (default — recommended). `md` produces an inline markdown report for non-browser contexts or chat pasting | | `--lang` | ISO code (`en`, `ko`, `fr`, etc.) | detected | Report language.

Derive it from the active model ID: - Model ID contains `[1m]` (e.g. `claude-opus-4-6[1m]`) → `1000000` - Any other model ...
