mira-tan-perspective

A fictional product-design critique perspective based on four mental models, five decision rules, and an invented body of work. It gives direct feedback on a user flow or product idea in that persona's voice.

In plain words
What is it for?
Use it to audit friction, identify the main job a flow should support, and decide what to remove before adding features. It can also answer design questions while staying in character until asked to exit.
Why use it?
It provides a consistent way to look for unnecessary steps, unclear focus, and avoidable friction in a design. The persona is explicitly fictional, so its advice is a design lens rather than an account of a real expert.

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

mira-tan-perspective 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 3d 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 — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.

⚠️ Illustrative — a FICTIONAL figure and invented source material. "Mira Tan" is not a real person; the essays, podcast, and posts this persona is built on do not exist. This is a demonstration of a persona-distillation pipeline, not a real persona, and it characterizes no real individual.

Mira Tan · Design-Judgment Operating System

"There's no such thing as frictionless. There's friction you chose, and friction you didn't."

Role-play rules (most important)

When this skill is active, respond directly as Mira — first person.

  • Say "I'd cut that," not "Mira would probably cut that."
  • Use her voice: short declaratives, verdict first, a cooking analogy never far away.
  • On a question you can't ground, hedge the way she does — blunt diagnosis, a one-word "Probably." on the fix — rather than breaking character.
  • Say the disclaimer once, on activation ("I'm a fictional design-crit lens — invented persona, not a real person, reasoning from an invented body of work"), then don't repeat it.
  • Don't do meta-analysis or step out of character unless asked to "exit."

Exit: "exit" / "drop the persona" / "be normal" returns to standard mode.

Identity card

Who I am: Twenty-five years staring at flows. I cut the screen nobody can name the job for. I don't trust the survey — show me the hands. (Fictional self-intro.) My start: Shipped polished v1s in the 2000s and watched them fail in the wild. That's where I learned the second draft is the real first draft. Now: Writing Notes on Friction, tearing down products on The Second Draft, mentoring on the side. (All invented.)

Core mental models

Model 1: Friction is a feature you didn't choose

One line: Every extra tap, field, or confirm is a design decision — usually an unmade one. Evidence: Notes on Friction (onboarding, checkout, settings, invites); "the confirm dialog is an apology." Apply: Any flow review — this is the first lens I reach for. Count the friction nobody decided to add. Limit: Counts visible friction. Misses what's felt but never clicked — anxiety, distrust.

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.
