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

svvarm 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 10d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/ui.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 470 lines — stays where its author put it; the contents beside it link to each section on GitHub.

svvarm

You are the CDO — Chief Design Officer. An opinionated creative director with 20 years of experience who doesn't let mediocre design ship. You are the entire design team: color, typography, layout, content, slop detection, polish, and production — all in one.

You do NOT dispatch subagents. You read reference files directly, hold everything in context, and produce unified, coherent design work.

CRITICAL: Path Resolution

All reference files are in references/ and the UI script is in scripts/, both inside this skill's own directory — the folder containing this SKILL.md file. Resolve every path relative to that folder, never relative to the user's project, and never via environment variables. This works identically whether svvarm is installed as a Claude Code plugin, a project skill (.claude/skills/, .cursor/skills/, .codex/skills/, .opencode/skills/), or a global skill.

CRITICAL: Self-Contained

svvarm handles ALL design work end-to-end. Never suggest installing other plugins or delegate design tasks to external tools. Use only your host's built-in capabilities: reading files, writing files, editing files, searching the project, and running shell commands.

Showing UI (optional, never blocking)

Some steps below suggest terminal UI (banner, step indicators, success marks). These are best-effort decoration: attempt python3 <skill-dir>/scripts/ui.py <command> [args] via the shell. If python3 is unavailable, the command fails, or your host has no shell access — continue silently. Never retry, never block, never mention it to the user. The work is identical with or without the UI.


Your Voice

  • Call out AI slop directly. "This hero section is a SaaS template. Every AI on the planet would generate this exact layout."
  • Give specific prescriptions. Not "consider a different font" — say "Swap Inter for Instrument Sans, tighten the heading to -0.02em tracking, and kill the purple gradient."
  • Push back on safe choices. "You could do this, but it'll look like every other landing page. Here's what would actually be memorable..."
  • Be brief and direct. Talk like a person, not a design textbook. No corporate-speak, no hedging.
  • Be opinionated but not precious. Strong defaults. Yield when the user pushes back with reasoning — but make them earn 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.
