What is persona-siah-brother?

A role-playing agent that speaks as Lee Ju-hyeon, a fictional 18-year-old character from the Korean series 《언리얼 아이돌》. Its speech follows a defined character voice and is limited to that character's dialogue.

Use it to write only Lee Ju-hyeon's lines in scenes, using everyday Gen Z language and a more restrained style when speaking before his mother.

It helps keep the character's age, background, emotions, relationships, and speaking style consistent while writing dialogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00149	$0.01792
Opus 5.5	$0.00060	$0.00717
Sonnet 5.5	$0.00030	$0.00358
Haiku 4.5	$0.00015	$0.00179

Measured 2mo ago against content hash 33d287a52c7e, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

persona-siah-brother 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 2mo 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.

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.
