General tool: generate charts as image assets (for posts/media)

[chubes4]

Why

We frequently want to generate simple charts (bar/line/pie/comparison) as images for use in WordPress posts, social, or as sellable assets. Today this lives in external automation (Sweatpants), which limits composability for in-plugin agents.

Proposal

Add a general tool (AI Tool / ability) that can generate chart images from structured data and return either:

• a local file path (for subsequent steps), and/or
• an uploaded attachment_id via existing WP media helpers.

Suggested interface (rough)

Tool name idea: generate_chart
Inputs: chart_type, title, series[], labels[], width, height, theme, format (png/webp), optional alt_text, optional post_id (attach).
Outputs: path, optional attachment_id, mime_type, width, height.

Acceptance criteria

• Deterministic chart rendering (no AI image generation)
• Produces optimized PNG/WebP
• Works in background jobs (no UI requirement)
• Clear errors + remediation hints

Notes

Recipes plugin can wrap this for higher-level “content briefing” style workflows.
