Skills · not prompts

Installable skills for Claude Code — built from a brain that actually runs.

These aren't prompt templates. They're SKILL.md packages you drop into Claude Code and it gains a new capability — same shape as installing a package from GitHub. Each one was extracted from the workflows of a live 11-node AI brain in production at Praefex.

If you know much about programming, the architecture story below is the part you'll enjoy. If you just want the skills, scroll to the catalog.

★ Flagship

The skill that fixes the one thing everyone hates about AI: it forgets.

$2 / month · cancel anytime · your data stays yours

Point Claude Code at a folder once. From then on, every session reads it, writes to it, and picks up exactly where you left off. Decisions you made. Preferences you stated. Mistakes you already corrected once and never want to correct again. Your project's actual context — not the cheerful "Hi! How can I help?" you've heard a thousand times.

Subscription Radar
Catches the $9.99 that quietly became $12.99, the free trial that auto-converted in week three, the streaming services you forgot overlap by 80%. Doesn't cut anything for you — refuses to let things slide.

Statement Scrub
Drop your last bank statement in — PDF, CSV, copy-paste, doesn't matter. Couple seconds later you're looking at where the money actually went. Stays local. Pays for itself the first month.

$15
Unanchor
A safety layer for any Claude session that touches your host system. Audits every shell command before execution. Doesn't trap your AI — just makes it show its work before pulling the trigger.

$5
Verified Answer
For the moment you need to KNOW, not guess. Forces source citation, flags weasel-words, refuses to fabricate when sources are silent — and tells you it refused, which is the part you actually need.

$7
Fleet Pulse
Up to 10 endpoints, scheduled health checks, learns the normal traffic shape over 24 hours, shouts when something deviates. Honest, small, sleeps when you sleep. Datadog at indie scale.

$8
Safe Nightly Reboot
Drains gracefully, snapshots state, reboots, runs post-boot health check, reports back. If data would be lost, refuses and tells you why instead of just doing it.

$15
Token Thrift
Watches how your sessions actually consume tokens. Pushes the cheap stuff to cheap tools, summarizes when context bloats, reports your weekly savings in dollars. People typically see 5-10× reduction.

$9
Digest First
Catches the moment before you paste 4,000 lines of log into Claude. Pre-summarizes with head/tail/grep/structured-extraction. Same answer, fraction of the tokens, faster too.
Buy on Polar
$12
Agent Offload
Roughly half the things Claude gets asked to do, bash already does better. Routes the trivially scriptable stuff to bash, saves Claude's actual thinking for the part that needs a brain.

Local Transcribe
Audio in, transcript out, nothing touches the cloud. Built on whisper.cpp with large-v3-turbo. Custom lexicon for industry jargon. Most technically grounded skill in the catalog.

How it's built

Skills extracted from a live consensus brain

These skills weren't speculated. They were lifted from the daily workflow of an 11-node Praefex brain currently running consensus-pathway verification, curriculum-gated learning, and append-only hash-chained audit.

What that means in practice:

The skills you can buy here are the procedural patterns from that brain, packaged as installable SKILL.md files. Same shape, smaller surface area, immediately useful in any Claude Code session.

Built by a single operator-architect using today's AI engineering technology — architectural design, methodology, and constitutional rules are human-authored; code execution is delegated to AI agents working across an 11-node mesh. From concept to functioning brain in roughly four months.
