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

container-tech-shell 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 6d 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.

What it actually says

container-tech-shell

Visual target (learned)

  • Near-dark or paper base with large framed containers defining composition
  • Containers drive hierarchy: bordered shells, inset panels, side rails, corner squares
  • Technical structure: thin borders, vertical frame lines, measured spacing
  • Optional focal energy (glow, ring, underlight) tied to brand accent, not a fixed hue family
  • Clean type + mono utility labels

Implementation

  1. Centered max-width master container with visible outer boundaries
  2. Layered treatments: framed cards, optional soft gradient edge, translucent panels when glass-shell-craft allows one shell
  3. Corner markers / rails (pairs with split-panel-technical brackets)
  4. Motion: masked reveals, slow pulse on focal glow only — pause offscreen / reduced-motion

Tuning knobs

Accent mood from brandAccent; roundness vs crisp frames; funk factor (focal objects); lighting concentrated on hero; structure density of rails/corners

Tell remap

  • Default accent = Taste brandAccent / --c-accent (never hardcode fuchsia/violet)
  • SaaS conversion still prefers product-proof over decorative orbs
  • Pair with paper-technical-frame or dark-premium shells

Avoid

Flat dark pages with accent but no container hierarchy; neon on every surface; generic equal card grids; mixing many unrelated accent colors.

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.
