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.

SkillSpector: 3 findings, up to high
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 →

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 | $0.00123 | $0.00947 |
| Opus 5.5 | $0.00049 | $0.00379 |
| Sonnet 5.5 | $0.00025 | $0.00189 |
| Haiku 4.5 | $0.00012 | $0.00095 |
Grade A, and why
ExtractWisdom 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 today.
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 — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ExtractWisdom — Dynamic Content Extraction
Pulls the best ideas out of videos, podcasts, interviews, and articles. It reads the content first, detects what kinds of wisdom are actually in there, then builds custom sections around what it finds instead of forcing the same headers every time. Five depth levels from Instant to Comprehensive. At Full (the default) and Comprehensive, output ends with a one-sentence takeaway, an "If You Only Have 2 Minutes" list, and references worth following. Alpha is the narrower cut: only the ideas that are new to a well-read reader, as N short ranked bullets. Both intents are our ports of Fabric's extract_wisdom and extract_alpha, written as ideal states.
Ideal State
- A reader who has two minutes gets the specific ideas, quotes and contrarian takes that make this piece worth their time, in sections named for this content rather than a fixed template.
- Every bullet sounds like the principal telling a friend about it, and every detail comes from this content, never from the calibration samples.
- Contrarian takes are mandatory: a genuinely hot take from the speaker appears undiluted, because spicy takes are the most memorable and shareable material.
- An Alpha run returns exactly the N ideas asked for (24 by default), ranked by how new they are, each short and faithful to the source, or fewer with a note when the content has fewer.
- The structure matches the requested depth level (Full by default) and passes the Quality Check in
Intents/Extract.md§ Output format; theextractwisdom-contracteval separately checks that insights come from the source and that a contrarian take appears.

What ships with it
4 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.

ExtractWisdom is a skill published in the GitHub repository danielmiessler/LifeOS (19,616 stars, last pushed today), licensed MIT. It adds 123 tokens to every session and 947 once invoked, about $0.0005 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.
