L1
Core OS
CLAUDE.md · brain/ · memory · command center · session continuity
10 components
▾
What it is: The foundation Claude reads at every session start. Tells Claude who you are, how you work, what's locked, what NOT to ask. Persistent across sessions, version-controlled, self-improving.

AI Executive Team
Autonomous agents that act as CMO, CTO, CFO, VP CS, VP Revenue
10 agents
▾

Quality Gates
Code-enforced checks. Bad output never ships.
10 gates
▾
What it is: A wall of automated validators that block low-quality output before it reaches you or your customers. Every "must" in your CLAUDE.md becomes code, not a wish.
Visual QA — Renders pages, catches empty tables + stale data.
Deploy gate — Hard block on bad deploys, fail-closed.
Drift detector — Flags when reality drifts from spec.
Honesty check — Catches "claimed done but isn't" lies.
Spec validator — Output checked against contract.
Brand consistency — Pricing + positioning never drift.
PII scrubber — Personal data never leaks customer-facing.
Content quality scorer — Email + social must score ≥8 to send.
Regression checks — Old features still work after new fixes.
Verify-before-complete — "Done" requires gate-pass, not text.
L5
Self-Improvement Engine
Every error becomes a permanent automated check.
8 components
▾
What it is: The OS gets smarter every day. When something goes wrong, the engine writes a new rule, wires a new gate, and prevents that class of error forever. Compounds over weeks.
Learning engine — Captures patterns from every session.
Error pattern tracker — Spots recurring issues + proposes fixes.
Rule promotion — Validated patterns auto-promote to enforcement.
Session scorecard — Every session graded; trend tracked.
Loop metrics — Throughput, accuracy, cost per task.
