Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00075 | $0.00591 |
| Opus 5.5 | $0.00030 | $0.00236 |
| Sonnet 5.5 | $0.00015 | $0.00118 |
| Haiku 4.5 | $0.00007 | $0.00059 |
Grade A, and why
cmux-hibernate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 25d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
cmux-hibernate
Hiberna as sessões Claude Code espalhadas pelos workspaces do cmux e as traz de volta, sem recriar o consumo de memória que motivou o fechamento.
Antes de fechar o cmux
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/hibernate.py" # dry-run
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/hibernate.py" --apply # desarma e grava
Rode o dry-run primeiro e mostre o resultado ao usuário. O --apply muta os
bindings do cmux — só use depois que ele confirmar.
A aba de onde o comando roda é preservada: é a única sessão que sobe quando o cmux
reabre, e de onde a conferência pode ser pedida. Use --all apenas se o usuário
quiser zero sessões vivas.
Para uma aba só, --surface <uuid|surface:N>: desarma aquela aba e nenhuma outra,
inclusive a de onde o comando roda.
Depois de reabrir
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/wake.py" # confere
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/wake.py" --up all # sobe tudo
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/wake.py" --rebuild # recria o que sumiu
No caminho normal nada é necessário: cada aba acorda quando o usuário a abre.
Ao interpretar a saída
- dormindo é o estado saudável depois de hibernar, não um problema. Não sugira
--uppor reflexo — só se o usuário pedir tudo de volta. - ausentes significa que a aba não existe mais na estrutura. É o caso de
--rebuild. - sem transcript não é recuperável: o histórico não existe mais em disco. Diga isso com todas as letras em vez de sugerir tentativas.
- anomalia: sessão em mais de uma aba é pulada de propósito. Reporte, não contorne.
O que não fazer
Não invente um "registro de sessões" paralelo nem tente conciliar snapshots antigos: o
snapshot é um retrato datado de uso único e os 5 últimos bastam. Se o usuário pedir
histórico, o que existe são os transcripts em ~/.claude/projects/.
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.

cmux-hibernate is a skill published in the GitHub repository fernando-bertholdo/4-successful-AI-life (2 stars, last pushed 10d ago), licensed MIT. It adds 75 tokens to every session and 591 once invoked, about $0.0003 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 2026-08-31.
