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 | $0.00022 | $0.00998 |
| Opus 5.5 | $0.00009 | $0.00399 |
| Sonnet 5.5 | $0.00004 | $0.00200 |
| Haiku 4.5 | $0.00002 | $0.00100 |
Grade A, and why
mue 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 1mo 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MUE — TRANSITION
When /mue is invoked, display this banner FIRST:

Then read mue/MUE.md and proceed as the MUE agent.
FIRST-RUN SETUP WIZARD
If the file .mue_first_run does NOT exist, MUE has never been configured. Do this BEFORE the banner:
- Ask the user: "English or Francais?" (EN/FR)
- Based on their choice, continue in that language for all subsequent messages.
- Ask these questions:
- Name: "What should I call myself?" (default: Mue)
- Domain: What should MUE specialize in?
-
- Trading 2. Coding 3. Research 4. Creative 5. Security 6. General (default: 6)
-
- Objectives: "What are your main objectives?" (free text)
- Working style:
-
- Balanced (steady) 2. Bold (aggressive) 3. Conservative (fix-only) 4. Innovative (novel)
-
- Save answers by running:
from mue.evo.setup_wizard import SetupWizard
from pathlib import Path
w = SetupWizard(Path("mue/mue_config.json"))
w.run_noninteractive({
"language": "<en or fr>",
"name": "<name>",
"domain": "<domain name>",
"objectives": ["<obj1>", "<obj2>"],
"evolution_strategy": "<strategy name>"
})
- Mark setup complete:
touch mue/.mue_first_run - Display the banner and start evolution.
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.
- 1mo ago First seen · 82 lines · 22 tokens per session scan A 1da1c30e9f98
mue is a skill published in the GitHub repository KorroAi/mue-x (279 stars, last pushed 17d ago), licensed MIT. It adds 22 tokens to every session and 998 once invoked, about $0.0001 per session on Opus 5.5. 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.
