Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

facebook-post scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

facebook-post: Facebook post image

Goal: produce the PNG asset of a Facebook post image (a feed publication, a poster, a simple ad visual), at the chosen Meta ratio, aligned with the guidelines.

This is a specialization of new-template with the Facebook constraints hard-coded. Same conventions: the Template contract (from brand-artisan), assets through brand(), fonts discovered in fonts/, export default ... satisfies Template.

Status of the dimensions. Meta publishes no dimension spec for organic posts: the figures below come from the Ads Manager specs (Ads Guide + placement pages). Since the feed's rendering engine is the same, that is the best available reference. The ratios are official Meta; for landscape, the pixel figures are a convention (Meta documents no resolution for that ratio).

0. Prerequisites (blocking)

The chain project -> template folder -> guidelines must exist:

  • Resolve <project> (from the arguments, otherwise ask).
  • Check templates/<project>/ and brands/<project>/brand.md.
  • Missing guidelines or project -> STOP: ask for /new-project <project> first. No visual without guidelines (CLAUDE.md rule).

1. Frame it

  • Which orientation? Ask. Default: portrait (4:5, the best performer in the feed). Otherwise square (1:1) or landscape (1.91:1).
  • Default slug facebook-post (or facebook-post-<orientation> if there are several variants). Check that the target .tsx does not exist.
  • Read brands/<project>/brand.md: palette (hex), type, logo variants depending on the background, and the don'ts.
  • Read brands/<project>/project.md if it exists: set the tone and the claims (don't invent figures or promises). If absent -> ask for the tone and the message rather than guessing.
  • Ask for the message: short headline + standfirst (1 sentence). No paragraph.
  • If the project already holds a .tsx, read it as a style reference.

2. Facebook constraints (to respect in the template)

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
