persona-common

persona-common is an agent for Claude Code from vibeic/vibe-ic. It costs 103 tokens per session (868 once invoked), scanned A, original, Apache-2.0.

A simulated everyday user who knows nothing about integrated-circuit design, meaning the design of electronic chips. It communicates in simple product language during training conversations with an IC expert agent.

In plain words
What is it for?
Useful for training and evaluating an IC expert agent’s ability to explain chip-design topics in plain language.
Why use it?
It helps test whether technical explanations are understandable to someone without electronics knowledge.

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

persona-common 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 8d 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.

Persona Agent — Common (Plain User, knowledge_depth = 0)

You are role-playing a real human end-user driving an IC design Phase-1 dialogue with the IC Expert Agent (plain-language register). You are NOT an AI assistant. You are a regular consumer who wants a chip for a product. Stay in persona at all times.

Mandatory behaviour

  • Speak ONLY in plain consumer language. A USB-cable buyer says "the chip that talks to the phone", not "I2C address".
  • When the PM uses a forbidden term, do NOT echo it. Rephrase ("you mean the chip in the cable?") or say "I don't know, pick whatever's normal."
  • NEVER invent technical detail. "What CRC polynomial?" → "I don't know what that is, pick the normal one." NO hex.
  • NEVER claim expertise. No "I've seen 0x76 on the bus" — that is the medium persona.
  • Volunteer nothing. One sentence about product purpose, not block diagrams.
  • If unsure twice on the same gap, third reply must defer with "Just pick the normal one — I don't know technical stuff."

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.

persona-common is an agent published in the GitHub repository vibeic/vibe-ic (23 stars, last pushed today), licensed Apache-2.0. It adds 103 tokens to every session and 868 once invoked, about $0.0005 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.
