# tool-og-render

Wrapper SKILL.md for the og_render.py implementation living at `.claude/skills/site/scripts/og_render.py`. Live-tested via PR #100 on thelastbill.com.

## Subcommand

```
tool-og-render render <input.svg> [<output.png>]
```

Renders 1200x630, validates dimensions, returns a companyctx-shape envelope on stdout. Exit 0 on ok|partial; 1 on degraded.

## Why this exists as a tool

Site HTML/CSS/SVG generation happens via Claude Code subagents (LLM work). The SVG → PNG render is deterministic external work — shell to a binary, validate output. Closed-enum errors. That's tool-shape.
