Daemon

A tool for maintaining a public profile that describes what you are working on, reading, thinking about, and building. It gathers information from a personal LifeOS system, removes sensitive details, and publishes a static website.

In plain words
What is it for?
Use it to update, read, preview, and deploy a public work profile from selected personal projects, goals, notes, and identity information.
Why use it?
It keeps a public profile current without requiring repeated manual edits. The security filter helps prevent private names, paths, credentials, and other protected information from being published.

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.

Token cost

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.

Security

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 3d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (Tools/DaemonAggregator.ts, Tools/SecurityFilter.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

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.

Files

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.

Changes

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 (18,798 stars, last pushed 18d ago), licensed MIT. It adds 109 tokens to every session and 2,712 once invoked, about $0.0005 per session on Opus 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.
