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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00084 | $0.00763 |
| Opus 5 | $0.00042 | $0.00381 |
| Sonnet 5 | $0.00017 | $0.00153 |
| Haiku 4.5 | $0.00008 | $0.00076 |
Grade A, and why
IterativeDepth 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 6d 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 — 62 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/IterativeDepth/
If this directory exists, load and apply any PREFERENCES.md, configurations, or resources found there. These override default behavior. If the directory does not exist, proceed with skill defaults.
IterativeDepth
What It Does
IterativeDepth examines one problem through several structurally different lenses — literal, stakeholder, failure, temporal, and more — merging what each angle surfaces into ISC criteria a single pass misses. Grounded in 20 established techniques across cognitive science, AI/ML, requirements engineering, and design thinking (see ScientificFoundation.md).
The Deliverable
A done run produces:
- A deduplicated ISC set — each criterion binary-testable, 8-12 words, phrased as a state not an action. No two criteria restate each other.
- Refinements to existing criteria, each noting what changed and why.
- Anti-criteria — failure modes that must NOT happen.
- At least one surprising cross-angle finding — a requirement that only appeared because two lenses collided. A run that surfaces nothing a single pass would have missed added no value.
Passes stop when a new lens repeats what earlier lenses already found. Non-redundant angles are what matter; more angles for their own sake are not.
The Lenses
TheLenses.md is a catalog of eight exploration angles. Draw from it — pick the lenses the problem calls for, in whatever order, as many as earn their keep. No fixed count, no prescribed sequence: a security problem leans on the failure and adversary angles, a UX problem on the experiential one. Let the problem select the lenses.

What ships with it
3 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.

IterativeDepth is a skill published in the GitHub repository danielmiessler/LifeOS (18,899 stars, last pushed 2d ago), licensed MIT. It adds 84 tokens to every session and 763 once invoked, about $0.0004 per session on Opus 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.

maaslalani-cli-style
Build CLIs and terminal tools in the style of maaslalani (slides, nap, sheets, gambit, typer, invoice, gum). Use when designing or building a new CLI/TUI tool, restructuring an existing one, or reviewing a terminal tool's UX, layout, keybindings, or README.
i-have-adhd
Action-first, zero-filler replies for a reader who loses the thread in prose. Use when the user asks for terse or direct answers, says too long, get to the point, tldr, stop rambling, or when replies keep getting cut off or ignored.
plan-devex-review
Interactive developer experience plan review. Explores developer personas, benchmarks against competitors, designs magical moments, and traces friction points before scoring. Three modes: DX EXPANSION (competitive advantage), DX POLISH (bulletproof every touchpoint), DX TRIAGE (critical gaps only). Use when asked to…
plan-tune
Self-tuning question sensitivity + developer psychographic for gstack (v1: observational). Review which AskUserQuestion prompts fire across gstack skills, set per-question preferences (never-ask / always-ask / ask-only-for-one-way), inspect the dual-track profile (what you declared vs what your behavior suggests), and…
tabw
Use when the user asks to "continue every session", "send this to all windows", "/ar:tabw". Acts on Claude sessions across tmux windows; destructive to in-flight work, so it states what it will do before doing it.
tabs
Use when the user asks to "list my claude sessions", "which windows are waiting", "/ar:tabs". Discovers Claude sessions across tmux windows and reports which need attention.
