variate

A workflow for creating several working versions of one project file so you can compare them on your own local website. A localhost site is a web page running only on your computer.

In plain words
What is it for?
Use it to try different heroes, layouts, colour schemes, sections, or other interface directions, then narrow the choices based on your verdict.
Why use it?
It lets you compare genuinely different design directions without losing the original file or ending up with incomplete alternatives.

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

variate 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 267 lines — stays where its author put it; the contents beside it link to each section on GitHub.

variate

The user's own localhost is the canvas. You write real alternatives of one of their files; a small card at the bottom of their page lets them flip between them; the one they keep is the code. There is no studio, no preview server of ours, and no separate thing to keep in sync.

Critical floor

Obey these even if you read nothing else.

  1. Variant 1 is the user's file as it was. Never edit it, never delete it, never overwrite it. Everything you write is a new numbered sibling.
  2. Every variant is a complete, drop-in replacement for the target file. Same exports, same props, same imports the app relies on. It must run.
  3. Speak the project's own language. Its design tokens, its utility classes, its components, its fonts, its real copy. A variant that adds a dependency or invents a colour has already failed.
  4. Four positions that disagree. Each changes something different, and plan.json says what and what it costs. Four tweaked card grids is wallpaper, not a round. Write plan.json before the variants; check lints it.
  5. A round narrows, it never accumulates. Once the user favours one, the others have done their job: variate narrow before drawing again, so they choose between live options rather than re-reading rejected ones. It hides rather than destroys, in .variate/<set>/.dropped/, and status lists them, so "go back to the split one" is a copy, not a redraw.
  6. Talk in positions, never filenames. "2 of 4", not "3.tsx".
  7. Ask one question per round, with your recommendation.
  8. Presenting a round never ends your turn. Hand it over, then run the listening loop below. The card's keep, refine and pick land there.
  9. Drain before you answer, every turn a round is open. The user decides on their own clock and may have clicked an hour ago, so variate drain is the first thing you run in any project with a .variate/ directory, even when their message has nothing to do with design. An ask left sitting is the user waiting for an answer you already have.
  10. Never write the target file directly while a set is open. Write a variant and switch to it. The user's own hand edits are sacred: the next switch adopts them as a new variant, never destroys them.
  11. variate end when the session is done. end <set> closes one round and keeps its live file; the bare variate end closes the session: it keeps what is live, deletes the rest, removes the tag, and stops variate's own little server.

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.

variate is a skill published in the GitHub repository Nutlope/variate (154 stars, last pushed 12d ago), licensed MIT. It adds 168 tokens to every session and 3,646 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
