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 Data Exfiltration · line 17 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
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 | $0.00109 | $0.02712 |
| Opus 5.5 | $0.00044 | $0.01085 |
| Sonnet 5.5 | $0.00022 | $0.00542 |
| Haiku 4.5 | $0.00011 | $0.00271 |
Grade A, and why
Daemon scanned grade A with 1 finding 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.

The opening of the file, as written. The whole thing — 207 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Customization
Before executing, check for user customizations at:
~/.claude/LIFEOS/USER/CUSTOMIZATIONS/SKILLS/Daemon/
If this directory exists, load and apply any SecurityOverrides.md or PREFERENCES.md found there. These override default security classification. If the directory does not exist, proceed with skill defaults.

Daemon Skill
What It Does
Manages your public daemon profile — a living page of what you're working on, thinking about, reading, and building. It pulls data from your LifeOS system, runs it through a deterministic security filter so only publicly safe content survives, and deploys a static site. Workflows cover update, read, preview, and deploy.
The Problem
You want a public presence that stays current without hand-editing a profile page every week, and without ever leaking private data. Your real context lives in LifeOS — goals, projects, ideas, identity — mixed with things that must never go public: contacts, finances, health, names, paths, credentials. Manually copying the safe parts is slow and one slip publishes something you can't take back. This skill aggregates the safe sources, blocks the sensitive ones at the code level, and gives you a preview-then-approve gate before anything ships.
How It Works
The DaemonAggregator reads LifeOS sources and merges them into daemon-data.json; a deterministic SecurityFilter (pattern matching, not an LLM) strips names, paths, credentials, and internal refs; the deploy step builds a fully static site. Sensitive files are never opened by the aggregator at all.
Workflow Routing
| Workflow | Trigger | File |
|---|---|---|
| UpdateDaemon | "update daemon", "refresh daemon" | Workflows/UpdateDaemon.md |
| ReadDaemon | "read daemon", "check daemon", "daemon status" | Workflows/ReadDaemon.md |
| PreviewDaemon | "preview daemon", "daemon diff" | Workflows/PreviewDaemon.md |
| DeployDaemon | "deploy daemon", "push daemon", "ship daemon" | Workflows/DeployDaemon.md |
What ships with it
7 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.

Daemon is a skill published in the GitHub repository danielmiessler/LifeOS (19,491 stars, last pushed 1mo ago), licensed MIT. It adds 109 tokens to every session and 2,712 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
