Your AI Usage Card, in one paste.
A prompt you run in your own Claude Code. It audits your real setup and habits — verification, autonomy, parallelism, memory, cache — and prints a calibrated card: your level (L0–L5), your ≈ adoption step, and your one next unlock. Then the ladder below turns that level into a path.
Open Claude Code in any project, paste the whole prompt, let it run
(~1–2 min). It works entirely on your machine and sends nothing automatically.
At the end it prints your card plus a USAGE_CARD_JSON= line — sharing
that line back via the form on this page is optional.
What comes back
A real card — this one is mine, measured, not self-declared.
| Level | L4 — Harness Engineer |
|---|---|
| ≈ Cherny | Step 3 — Supervised Autonomy · next unlock: cost-lanes + exception-monitoring |
| Why | Authored, git-versioned hook lifecycle with an exit-2 stop verification gate; agent teams in use; scheduling evidenced. |
| Operates | verify: enforced · autonomy: wide+guardrails · steering: low · reviews: summaries |
| Parallel | routine-parallel — 549 subagent + 570 background runs, worktrees, 4 named teams |
measured 2026-07 · sharing the one-line JSON under the card is optional — one anonymous row, distributions only
Got your level? Find your rung.
Every rung expands into a hand-picked path — what to read, what to build next, and where I can help. That's the accompagnement: your card names the rung, the ladder hands you the path.
L5
Force Multiplier
Multi-agent at scale, evals & quality gates, tooling the whole team runs on.
Build
Evals over your own harness; share it as a team standard.
Work with me
CTO & longer missions — spread it across the org.
L4
Harness Engineer
You built and operate your own system: hooks, enforced verification, orchestration, living memory.
Build
Evals + exception-only monitoring; cost lanes per model.
Work with me
Half-Day Deep Dive — push toward team-scale.
L3
Agent Builder
Delegates real work to subagents & workflows, habitual verification, some machinery of your own.
Build
Your first lifecycle hook; give one agent living memory.
Work with me
1:1 Session or 4-Pack — author your harness.
L2
Power User
Tuned settings, skills & MCP in real use, some verification — still mostly hand-driving.
Build
A self-verification loop: make Claude prove its work before you read it.
Work with me
Power Hour — one concrete win on your setup.
L1
Daily Helper
Regular interactive use, little authored config, you eyeball the output.
Build
Plan mode before every non-trivial task; a real CLAUDE.md.
Work with me
Power Hour — set the foundations right.
L0
Explorer
Occasional chat-style use, default setup.
Build
Let it edit a real file today — agentic, not chat.
Work with me
Foundations session — the mental model first.
