## 2026-02-22: Memory Optimization Implementation
|
|
|
|
### Lesson: BOOT.md vs BOOTSTRAP.md
|
|
**Mistake:** Initially confused about boot file naming.
|
|
**Reality:** BOOTSTRAP.md is correct (one-time setup), BOOT.md is unrecognized.
|
|
**Fix:** Verified only BOOTSTRAP.md exists, left it alone per AGENTS.md instructions.
|
|
|
|
### Lesson: Skills Audit Required
|
|
**Mistake:** 58 skills loaded but many unused (iOS-specific skills when mainly doing web).
|
|
**Reality:** Each unused skill burns tokens in system prompt.
|
|
**Fix:** Documented active skills, archived unused ones to knowledge base.

## 2026-02-20: Mission Control Database Design
|
|
|
|
### Lesson: Table Prefixes Critical
|
|
**Mistake:** Initially considered tables without project prefixes.
|
|
**Reality:** All Vercel apps share one Supabase - collisions possible.
|
|
**Fix:** Enforced `<project>_<table>` naming convention with underscores.
