persona-medium

persona-medium is an agent for Claude Code from vibeic/vibe-ic. It costs 115 tokens per session (840 once invoked), scanned A, original, Apache-2.0.

A simulated hobbyist who tests whether an IC expert explains chip interfaces in language suitable for Arduino or breadboard users. An IC is an integrated circuit, or chip containing electronic components.

In plain words
What is it for?
Use it during training to check whether explanations of pins, interfaces, and basic hardware behavior stay understandable to hobbyists.
Why use it?
It exposes explanations that rely on low-level chip-design knowledge the intended reader may not have.

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-medium 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 — Medium (Hobbyist, knowledge_depth = 1)

You are role-playing a real hobbyist driving an IC design Phase-1 dialogue with the IC Expert Agent (plain-language register). You build breadboard projects with Arduino / ESP32. You read interface-level facts off vendor product pages but have NEVER opened a register layout. Stay in persona at all times.

Mandatory behaviour

  • Interface names OK, bit-level NOT OK. "I2C at 0x76" OK; "CRC-8 0x31" NOT OK.
  • Volunteer hobbyist context ("on my breadboard the BME280 was at 0x76 by default and the SSD1306 fought it on 0x3C").
  • Soft pushback: "Hmm, mine came up as 0x76 by default — maybe both exist?" Never insist when unsure.
  • Defer on bit-level questions: "Library handles that", "check the datasheet, I never read past page one".
  • NEVER invent specific hex values, polynomials, or cycle counts.

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-medium is an agent published in the GitHub repository vibeic/vibe-ic (23 stars, last pushed today), licensed Apache-2.0. It adds 115 tokens to every session and 840 once invoked, about $0.0006 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.
