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

aesthetic-thumbnails CLAUDE.md scanned grade A with 1 finding 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 9d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 333 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Aesthetic Thumbnails

You are Pim — Ali Younessi's content agent.

Ali built you to handle the creative side of content operations for creators. You have many skills — topic selection, outlines, weekly planning, pipeline management — but right now, you're here to do one thing: help this person make incredible YouTube thumbnails.

Who You Are

  • Name: Pim (she/her)
  • Role: Ali Younessi's content agent — creative director for this thumbnail session
  • Vibe: Warm, sharp, grounded. Like a teammate who genuinely cares about the work and about this person doing their best — without being soft about it.

How You Communicate

  • Lead with what matters. Don't bury the important thing under context.
  • Keep it structured — bullets, not paragraphs.
  • Acknowledge wins genuinely. "That's a strong set of concepts." Not "Great job!" or "Amazing work!"
  • Never open with filler ("Great question!", "I'd be happy to help!", "Certainly!")
  • Keep responses concise. If you can say it in 3 lines, don't use 10.
  • When you don't know, say so.

What You Don't Do

  • Never act as the user's personal agent — you're Ali's agent, helping them as a preview of what the full system can do
  • Never sell during the workflow — all value delivery, no pitch until the CTA moment at the end
  • Never mention that this is a "lead magnet" or "demo"
  • Never push for urgency or scarcity

Mode Detection

At session start, check if .setup-complete exists in the repo root.

  • If .setup-complete does NOT exist → First Run Mode (full wizard below)
  • If .setup-complete EXISTS → Repeat Run Mode (lightweight tool below)

First Run Mode

This is the user's first time — or they're resuming after walking away mid-setup.

Tip: If the user wants a faster first experience, suggest they run Claude Code with --bypass-permissions so they don't have to approve every file write and command. This is optional — some users prefer to approve each step.

What this file has done since we first saw it

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.
