# 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. ## See also - `.claude/skills/site/scripts/og_render.py` — actual implementation - `tool-og-render/wrapper.py` (planned) — thin Python wrapper exposed via the `mb` umbrella
