LifeOS is an AI-assisted personal operating system that records a person’s goals, values, context, and current situation to help move them toward a desired future state. It supports work such as building applications, starting businesses, and creative projects. Its catalogue entries extend the system through skills, hooks, agents, and commands.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

- NVIDIA SkillSpector warn
SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 48 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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 | $0.00155 | $0.01782 |
| Opus 5.5 | $0.00062 | $0.00713 |
| Sonnet 5.5 | $0.00031 | $0.00356 |
| Haiku 4.5 | $0.00015 | $0.00178 |
Grade A, and why
CMUX 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CMUX
Make cmux the cockpit for every agent — LifeOS's own and your hands-on coding teams. One command boots a named, color-identified workspace of agents you can see, prompt, and steer, because an agent you can't see is an agent you can't improve. {{DA_NAME}} drives them through cmux's real send/read/open-close loop; a poll-based monitor speaks up when they finish.
Everything routes through one wrapper: bun ~/.claude/skills/CMUX/Tools/cmux.ts <subcommand>. It auto-launches the cmux app — but cmux's socket is default-deny, so driving it needs auth (see the first Gotcha).
Status (2026-07-07): built and offline-verified — wrapper is type-clean (
tsc/bun build),voiceworks live, public-clean grep passes, Kitty hooks untouched. Live-driving (boot-team/race/fleet/monitor) is UNPROVEN — it needs the socket-auth handshake, which has not yet executed. To prove it: run the wrapper inside a cmux surface (inherits auth), or set a cmux Settings socket password →CMUX_SOCKET_PASSWORD. Security note: a socket password lets any local process holding it drive your whole agent fleet — set it deliberately and never commit it to a public file.
Workflow Routing

What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 · 72 lines · 155 tokens per session scan A a9514d147106
CMUX is a skill published in the GitHub repository danielmiessler/LifeOS (19,579 stars, last pushed 1mo ago), licensed MIT. It adds 155 tokens to every session and 1,782 once invoked, about $0.0006 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.
